Title: Heat insulating box body
Inventor: KOTORII TOSHIO
IPC: F25D23/00
Filed: 1989-06-28
Abstract: PURPOSE:To prevent the inflating deformation of an outer case during cooling operation as well as the inflating deformation of an inner case upon stopping the cooling operation by a method wherein the tape of aluminum foil, on the surface of which an urethane film is laminated previously, is employed for fixing a heat radiating pipe for the outer case of a heat insulating box body, which is made of a steel sheet, and a cooling pipe to an inner case made of plastics. CONSTITUTION:An urethane film 11 is laminated on the surface of the tape 4 of aluminum and is bonded strongly to a foamed insulating material 9 while the tape 4 of aluminum, on which an adhesive material 5 is laminated, is bonded to an outer case 2 made of a steel sheet and an inner case 6 made of a plastic. Accordingly, the foamed insulating material 9 will never be separated from the aluminum foil tape 4 because of the interposition of the urethane film 11 even when the aluminum foil tape 4 follows to the expansion of the outer case 2, made of a steel sheet, or the contraction of the inner case 6, made of a plastic, whereby any gap between both parts will never be produced. According to this method, the inflating deformation of the outer case 2 during cooling operation, which is generated by the stagnation of foaming agent in the foamed insulating material in the gap, or the inflating deformation of said inner case 6, which is generated by the expansion of the stagnated foaming agent due to a temperature rise near said inner case 6 upon stopping the cooling operation, may be prevented.

Title: Geometric shape test apparatus for sphere
Inventor: TEIBADARU FUERUDEI
IPC: G01B11/24
Filed: 1988-07-05
Abstract: PURPOSE: To obtain an accurate piece of information on the spherical property and the surface smoothness of a ball by projecting an image onto the ball to be tested and measuring a reflected image. CONSTITUTION: A ball 8 that is a body to be tested is placed on a seat surface 16 and a light source 10 projects a sharp image of a two-dimensional grid 1 onto the surface of the ball 8 via a semi-transmission mirror 2 and a lens system 3, thus enabling an image that is reflected from the corresponding part of the ball 8 to reach onto a screen 5 through a compensation lens 4 and hence determining the degree of sphere of the ball 8 from the formed image. Specifically, when the image indicates a cushion-shaped or a barrel-shaped distortion, the distortion indicates positive and negative deviation from an ideal diameter and the smoothness of the surface of the ball 8 can be determined from the change in the thickness of a grid line and the change in course.

Title: Semiconductor integrated circuit and manufacture thereof
Inventor: KANEKO SATOSHI
IPC: H01L21/822
Filed: 1995-06-30
Abstract: PURPOSE: To make it possible to form a resistor having no temperature characteristic without variation by diffusing impurities with which polysilicon is doped in a semiconductor layer through a slit to form a diffusion resistance region. CONSTITUTION: A slit 12 is formed in part of an insulating layer 11 on a semiconductor layer 10 to expose the semiconductor layer 10. A polysilicon layer 14 is formed which extends from the portion of the insulating layer 11 on one side of the slit 12 to the portion of the insulating layer 11 on the other side, covering the slit 12. Impurities in the polysilicon layer 14 are diffused in the semiconductor layer 10 through the slits 12 to form a diffusion resistor 18. This makes it possible to virtually determine the characteristics of the diffusion resistor only according to the impurity concentration of the polysilicon. Since the characteristics of the diffusion film can be determined only according to the condition of the polysilicon film, as mentioned above, it is possible to control variations and thus obtain a resistor having no temperature characteristic without variation.

Title: Electrode type water treating device
Inventor: TANAKA YOSHINORI
IPC: C02F5/00
Filed: 1995-06-08
Abstract: PURPOSE: To suppress the precipitation and adhesion of scale on the wall surfaces of water passages. CONSTITUTION: Electrodes 5, 6 are arranged to face each other via a spacing in a housing 4 connected to a water flow pipe and square polarity inverted voltage is impressed on these electrodes 5, 6. The inside walls of the passages in this housing 4 are insulated by an insulation coating of epoxy, etc., and the shortest distances B between both ends of the water flow passage in the housing 4 and the electrodes 5, 6 are formed larger than the inter-electrode distance A between the electrodes 5, 6, by which the flow of current to the water flow pipe side from the electrodes 5, 6 when the polarity inverted voltage is impressed on the electrodes 5, 6 is suppressed. The flow of the polarity inverted voltage between the electrodes 5 and 6 is thus ensured.  The water is activated by the current energy of the polarity inverted current, by which the dissolving degree of water is increased and the precipitation of the scale is suppressed.

Filed: 1981-10-19
Abstract: PURPOSE:To obtain defect-free sound nuggets by superposing two sheets of metallic plates allowing a clearance to exist therebetween, and maintaining the welding current value in the press-sticking period smaller than the current value in the melt sticking period. CONSTITUTION:Metallic plates 1, 1' to be joined are sandwiched by electrodes 2, 2' while a clearance is allowed to exist therebetween. Pressure is exerted between the electrodes 2 and 2', and the pressurizing force attains a set value, the  welding current for the 1st stage is run for a predetermined time (press sticking period). The weld tme is the time enough for the clearance between the plates 1, 1' to be eliminated and the plates to be press stuck thoroughly. The welding current is set at the value smaller than the welding current in the later deposition period. When the clearance between the plates 1 and 1' is eliminated and  both plates are press stuck thoroughly and fit well to each other, the welding  current required for ordinary deposition, that is, the current larger than the welding current for the 1st stage is run for the melt sticking period alone,  whereby the plates 1 and 1' are melt stuck to each other.

Filed: 1979-12-21
Abstract: PURPOSE:To perform accurate measurement over wide distances by mounting a transmitter and a receiver to the same structure and removing the evil effect by the signal component directly leaking from the transmitter to the receiver, without vibratively isolating these. CONSTITUTION:The 1st pulse which determines the generation time of the pulses transmitted from a transmitter 11 and the 2nd pulse of the pulse width larger than that of this pulse are generated from a pulse signal generating circuit 9, and the transmission pulses are transmitted toward an object 16 via the transmitter 11. The 2nd pulse is applied to a selective amplifier circuit 13 to which the signal of a receiver 12 is inputted so that amplifying operation is carried out only during that time. This is also applied to a processing circuit 14, so that the increase in the rate of attenuation of the receiving signal level caused with an increase in delay time along with an increase in the measuring distance is compensated. Hence, the signal component directly leaking from the transmitter 11 to the receiver 12 is eliminated and the accurate measurement is performed.

Title: Wide-band voltage variable oscillator
Inventor: KAWAGUCHI TAKATOSHI
IPC: H03B5/18
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To obtain a voltage variable oscillator having a function, where first and/or second feedback capacitances are reduced when an oscillation frequency is hightened by connecting the first feedback capacitance between a base and an emitter and connecting the second feedback capacitance between the emitter and a ground or the emitter and a collector. SOLUTION: The first feedback capacitance is constituted of a capacitor C1, a variable capacitor diode VD1 and a capacitor C2 in serial connection. The second feedback capacitance is constituted of the capacitor C3 and a variable capacitor diode VD2 in serial connection. The capacitances of the variable capacitor diodes VD1 and VD2 are increased when a synchronization voltage becomes low and decreased, when it is hightened. That is, the capacitance of the variable capacitor diodes VD1 and VD2 become larger, when the oscillation frequency is low and becomes smaller when the oscillation frequency is high. Therefore, the values of the first and the second feedback capacitances become smaller as the oscillation frequency lowers, so that an oscillation circuit is stabilized.
