Title: Ultrasonic endoscopic apparatus
Inventor: SHIONOYA KAZUNORI
IPC: A61B8/12
Filed: 1987-05-13
Abstract: PURPOSE:To prevent the generation of the noise caused by a contact system and to perform the transmission of a signal in spite of a small scale, by forming a signal transmitting means for converting the signal received by a rotationally driven ultrasonic vibrator to a magnetic signal and converting said magnetic signal to an electric signal in a non-contact system by utilizing galvanomagnetic effect. CONSTITUTION:A magnetic resistor element 17 showing galvanomagnetic effect is fixed in opposed relation to a coil 10 on the center axis of said coil 10 and an amplifying circuit 18 is provided behind said element 17 and amplifies a receiving signal to transmit the same to an external apparatus 4. In the ultrasonic endoscopic apparatus thus constituted, the signal received by an ultrasonic vibration part 6 is transmitted to a coaxial cable 16 and amplified by an amplifier 11 to enter the coil 10. The magnetic field of the coil 10 is detected by the MR element 1 to be converted to an electric signal which is, in turn, transmitted to the external apparatus 4 through the amplifying circuit 18. Herein, the element converting the magnetic field to the electric signal is put to practical use by the use of the MR element regenerating high density magnetic recording such as VTR and, since the size of the element is small, the apparatus can be made more small-scale in the case used in an ultrasonic endoscopic apparatus.

Title: Manufacture of composite molded item with steel
Inventor: KAMATA TAKASHI
IPC: B29K105/06
Filed: 1984-06-08
Abstract: PURPOSE:To produce a molded item excellent in strength and good in electromagnetic sheilding, by putting an expanded metal of a thin steel plate and a thermosetting resin together and molding them together. CONSTITUTION:A lath (expanded metal of a thin steel plate) 1 is worked into a shape in conformity with the shape of a bottom force 4. Then the lath and a molding material 2 of a thermosetting synthetic resin are put together and are inserted into the cavity defined by the bottom force 4 and a top force 3 that have been previously heated. Successively, the top force 3 is pressed, and the top force 3 and the bottom force 4 are heated to mold the lath 1 and the molding material 2 integrally. Thus a composite molded item 5 can be produced in the same conventional manner as for the molding of the thermosetting resins, and further the lath 1 can be prevented from breaking due to the molding material 2 that is filled in the cavity and is fluid when the molding is performed. The composite molded item 5 can be mass-produced and used as housing material for computers, etc.

Title: Steering structure fixed with vane
Inventor: MORI MASAHIKO
IPC: B63H5/16
Filed: 1982-07-05
Abstract: PURPOSE:To convert the rotary flow energy at the rear of a propeller effectively to thrust by securing upwardly inclined vanes having high base section on both sides of a member constituting a steering arranged at the rear of a propeller. CONSTITUTION:The vanes 2 secured on the steering 3 at the rear of a propeller 1 has the base section higher by the vertical distance H from the center P of the propeller shaft and inclined upwardly toward the tip. The inclination angle (beta) is determined by the vertical distance H to cross perpendicularly with the rotary flow Vtheta while the distance H is selected to be 0.2-0.4 of the propeller diameter to maximize the thrust with the magnitude of rotary flow and the vane area and the vane itself has the attack angle (alpha) against the oblique flow V2. Consequently the buoyancy L2 is increased to incline considerably against the vertical direction while the front and rear component Vx of buoyancy or the thrust is increased to reduce the shock pressure due to rolling.

Title: Production of aqueous dispersion and aqueous solution of water-soluble polymer
Inventor: CHIBA TOORU
IPC: C08L101/00
Filed: 1983-06-28
Abstract: PURPOSE:To provide a stable aqueous dispersion which can be transferred with a pump or filtered with a filter-press, etc. and gives a completely dissolved clear solution when mixed with an alkaline liquid, by compounding a water-soluble polymeric substance treated with an aldehyde compound, a carboxylic acid, a polyhydric phenol and water. CONSTITUTION:The objective dispersion is obtained by compounding a water-soluble polymeric substance treated with an aldehyde compound, a carboxylic acid, a polyhydric phenol, and an aqueous medium. As an alternative method, a water-soluble polymeric substance is treated with an aldehyde compound and a carboxylic acid, and compounded with a polyhydric phenol and an aqueous medium. The carboxylic acid is formic acid or acetic acid, and its amount should be increased when the aqueous dispersion is to be stored for a long period. The addition of the carboxylic acid inhibits the scission of the acetal bond between the aldehyde and the water-soluble polymer, promotes the dissolution-delaying effect of the polyhydric phenol, elongates the dissolution time of the water-soluble polymeric substance, and retains undissolved state for a long period without producing agglomerates.

Title: Probe
Inventor: MATSUZAKI MASAAKI
IPC: G01R13/20
Filed: 1993-05-19
Abstract: PURPOSE:To reduce the capacity of a capacitor at the end portion of a probe by using an amplifier having sufficient gains, in amplifying the output of a passive attenuating probe circuit having an amount of attenuation not less than a predetermined value, and restoring the amount of attenuation to an optimum value. CONSTITUTION:The low frequency component of an input signal is attenuated by resistances 1, 8 to a ratio of 20:1 and input to an amplifier 9. The high frequency component of the signal is divided by a capacitor 2 and by subsequent composite capacities, i.e., the composite input capacities of a cable 4, a variable capacitor 6 and the amplifier 9. In that case, the variable capacitor 6 is adjusted so that R1.C1=R2.C2 and a 20:1 attenuator having a flat frequency characteristic from DC to high frequencies on the screen of an oscilloscope is provided. The capacity of the capacitor 2 at an end portion 3 can be cut in half by setting the amount of attenuation to twice the conventional one. This attenuated signal is amplified and doubled by the amplifier 9, and the attenuation ratio is restored to 10:1 as the whole probe and the signal is input to an oscilloscope main body.

Title: Narrow-band noise eliminator
Inventor: SAKATA HARUO
IPC: H04J13/00
Filed: 1989-05-10
Abstract: PURPOSE:To reduce the deterioration of sent information by subtracting a composite signal from the output of an AGC when the level of the composite signal rises above a specific value. CONSTITUTION:An input signal 1 after being passed through a wide-band passing filter is multiplied by two mutually orthogonal subcarriers, passed through low-pass filters 13 and 14, and further multiplied by two mutually orthogonal subcarriers to generate their difference. Then when the difference is larger than a certain threshold value, the difference is subtracted from an original signal. Thus, the above-mentioned scan is repeated by using plural threshold values to remove narrow-band interference waves in order. Consequently, the narrow-band, large-amplitude interference wave of a spectrum spread(SS) signal which is received by a receiver is removed automatically to improved the SN ratio of an SS communication or increase the transmission distance of the communication.

Title: Vapor growth method of p type 3-5 group compound semiconductor
Inventor: MIZUTANI TAKASHI
IPC: H01L21/205
Filed: 1981-07-27
Abstract: PURPOSE:To obtain a p type III-V group compound semiconductor by simultaneously supplying the HCl and diethyl-zinc gases with the independent pipes from the upper-stream side of substrate and the lower-stream side of the III-group metal material. CONSTITUTION:The first and second bypass pipes 7 and 8 are provided. The mixed gas of the HCl introduced at a rate of 5cc/min and H2 introduced at a rate of 500cc/min from the pipe 1 reacts with the In 2 kept at a temperature of 800 deg.C and the InCl2 is sent to the lower-stream side. In the region 4, the pH3, diethyl-zinc and H2 are supplied respectively from the pipe 7 at the rates of 5cc/min, 0.004cc/min and 500cc/min, while the HCl and H2 from the pipe 8 respectively at the rates of 0.2cc/min and 500cc/min, and these are mixed and sent to the lower-stream side. Thereby the p type InP is deposited on the InP crystal 5 kept at 680 deg.C by the vapor growth deposition mthod. According to this method, the HCl and p type dopant(diethyl-zinc) introduced for suppressing growth on the pipe wall do not cancel each other the respective effects and can be introduced into the reaction pipe simultaneously. As a result, the growth rate of InP no longer depends on the flow rate of diethyl-zinc gas.

Title: Light-receiving circuit
Inventor: FUJIMURA KEIJI
IPC: G01J1/44
Filed: 1984-06-06
Abstract: PURPOSE:To prevent saturation of a photo-diode convert a photo-signal to an electric signl accurately, by installing a wave detecting circuit commanding change inversely proportional to an amplifier output signal level of a terminal voltage of a resistance circuit network and a control means consisting of transistor Q, etc. CONSTITUTION:An increased light quantity of a photosignal causes a composite resistance drop of a parallel circuit consisting of resistances R2 and Q and also of drop of a voltage appearing on an output terminal OUT. Reversely, a decreased light quantity of the photosignal increases the composite resistance of the parallel circuit consisting of resistances R2, Q and a level of a signal appearing on the output terminal OUT is kept constant. Further, an increase of a photosignal incident to a photo-diode PD lowers the composite resistance of the parallel circuit acting as a load resistance of the photo-diode consisting of resistances R2 and Q, preventing saturating condition of the diode PD. This prevents deterioration of S/N by an increase of a dark current.

Filed: 1991-05-22
Abstract: PURPOSE:To prevent the breakage of a light emitting tube, occurring when the cross section shape of the light emitting tube is formed in a noncircular one, without causing the lowering of ultraviolet ray strength. CONSTITUTION:This discharge lamp is a low-pressure mercury-vapor discharge lamp, in which electrodes 3 and 4 are sealedly mounted on both the end parts of a light emitting tube 1 composed of glass and also mercury and a rare gas are sealed in the light emitting tube, and which is lit by an input to a unit inner surface area or 0.3W/cm<2> or more. The luminous part cross section of the light emitting tube 1 is formed in a nearly elliptical or nearly square shape. Also the formulas of 0.7mm<=T1<=2.0mm and 0.9mm<=T2 are satisfied, where T1: the glass wall thickness in the short side direction of the luminous part cross section, and T2: the glass wall thickness in the long side direction. The mechanical strength of the light emitting tube can be improved without causing the lowering of ultraviolet ray strength, because the above conditions are satisfied by the glass wall thickness in the short side direction and that in the long side direction of the luminous part cross section which are actual irradiation directions of a ultraviolet beam.

Filed: 1984-06-08
Abstract: PURPOSE:To secure the even intensity of junction between the disk substrates and a spacer by bonding the spacer between two disk substrates with an adhesive and irradiating the ultraviolet rays on the revolving substrates to harden the adhesive. CONSTITUTION:Spacers 3 and 3' are attached to the inner and outer circumferential parts of a transparent substrate 1 containing a record layer 2 on a single side by means of adhesives 6 and 7. Then a substrate 1' containing a record layer 2' is put on the substrate 1. Both substrates 1 and 1' are adhered to each other and revolved slowly on a tool 5. At the same time, the ultraviolet rays are irradiated to adhesives 6-9 from an ultraviolet lamp 10. Thus these adhesives are hardened and a sealed hollow part 4 is formed between upper and lower substrates. This attains the even intensity of adhesion for both substrates, and the adhesion is possible even with an information recording substrate of a large diameter with irradiation of ultraviolet rays. This can increase the size of a device and avoid the rise of the heating temperature due to the increase of lamps.
