Title: Mold for press-molding optical element and production
Inventor: KURIBAYASHI KIYOSHI
IPC: C23F4/00
Filed: 1988-05-27
Abstract: PURPOSE:To produce a high-precision mold for press-molding an optical element by successively forming a heat resistant film of platinum group metals, a silicon film and the resist of a required pattern on the base material of sintered hard alloy having a required shape and performing dry etching. CONSTITUTION:A base material 11 of sintered hard alloy (or cermet) is worked to the shape close to a required shape and a platinum group metallic film (or an alloy film incorporating platinum group metals as a main component, a nitride film, a carbide film and a boride film) is coated on the surface as a heat resistant film 12 by a sputtering method. Furthermore after forming a silicon film 13 thereon by the sputtering method, a pattern is formed with a resist 14 so that a required final shape is obtained by photolithography. Then after performing anisotropic etching for silicon by a reactive plasma etching method and emphasizing the unevenness of the pattern formed with the resist 14, a high-precision mold for molding is manufactured by removing the whole part of both the resist 14 and the silicon film 13 and one part of the heat resistant film 12 by a plasma etching method. A high-precision optical element can be stably produced at low cost by utilizing this mold for molding.

Title: Signal recording position searching method and tape-like recording medium processor
Inventor: ITO KAZUNORI
IPC: G11B15/087
Filed: 1998-05-13
Abstract: PROBLEM TO BE SOLVED: To accurately search a tape position recorded with a required signal. SOLUTION: When a required target address Pt exists in an initial N segment of a track in ST (step) 3, tape fast-forwarding/rewinding is performed in ST10, and the tape position is moved to the top end side of the tape. When the address Pt doesn't exist in the segment, a present address Pd is discriminated in ST4. When the condition of ST6 is satisfied, and the address Pd is within the prescribed range set based on the address Pt, the searching is finished. When the condition isn't satisfied in ST6, a tape running amount is discriminated in ST7-9, and the tape position is moved within the prescribed range, and the searching is finished.

Title: Flow rate control device of air
Inventor: TAZAWA YOSHITOSHI
IPC: F16K31/10
Filed: 1990-05-23
Abstract: PURPOSE:To eliminate an over-shoot phenomenon, reduce hystersis, supply a stable rate of air by providing movable introducing passages and a seat with a sliding-valve mechanism. CONSTITUTION:When electric current is supplied to a solenoid valve 1, a controlling member 2 is attracted leftward and thereby an introducing passage 11 is opened by a rate corresponding to the supplied electric current. The position of the controlling member 2 is held with minute reciprocating movements. When the introducing passage 11 is opened, there is difference between values of pressure in an intake negative pressure chamber 13 and a pressure chamber 3, which is determined by the values in the intake passages 11, 14, whereby a valve body 5 is opened. Pressure difference is generated between an atmosphere chamber 12 and the negative pressure chamber 13, and applied to close the valve body 5. However, the valve body 5 is kept open because a diaphragm 6 has much effect. Then the air flows in a direction of an arrow to open the valve body 5, the introducing passage 11 is closed. The pressure difference between the passage 11 and the intake negative pressure chamber 13 is eliminated. Force of a spring 7 and pressure difference between the atmosphere chamber and the intake negative pressure chamber 13 are applied to close the valve body 5, and the introducing passage 11 is closed again.

Abstract: PURPOSE:To perform the recording/reproducing with a video track having the same recording length as a two-head type VTR and at the same time to attain miniaturization of a rotor, by using >=3 heads of the same azimuth angle which are attached to the rotor with equal angular intervals. CONSTITUTION:Six heads H1-H6 are attached to a rotor 6 with equal angular intervals, and the same azimuth angle is given to each head. A magnetic tape 2 is wound around the rotor 1 at angles alpha and beta for overlap recording with 300 deg. effective winding angle. Both the rotor 1 and the heads are revolved by F(n- n)/n number of revolutions per second (n: number of heads) when a video signal of field frequency F is recorded. The video signal is supplied selectively to either one of those heads by a switch circuit. For instance, the video signal is supplied only to the head H1 when it reaches the place near a guide pole 3. This supply of video signal is continued until the head H1 is set near a guide pole 4. Then the video signal is supplied to the head H2.

Abstract: PURPOSE:To utilize data stored in a memory for the use of plural kinds of devices by reading out the data of an outline character stored in the memory according to the set value of a storage means for reading method. CONSTITUTION:After developing outline font data for one character in a character data storage means 6, a value corresponding to a device in use is written in a storage means for reading method 8 through a CPU 1 or a data bus 10a. An address generating means 7 generates the address of the means 6 according to the set value of the means 8 and reads out the character data in order. Character data are changed to the read character data through a data changeover means 9 according to the set value of the means 8 and the read data are outputted to the bus 10a. When the character data stored in the means 6 are again read out successively for the use of another device, character data for a different device are read without again evolving an outline character by setting, in the means 8, a value fitted to a device to be used newly.

Abstract: PURPOSE:To impress a driving voltage to an electrostrictive element joined to a suspension spring, to reduce a starting torque at the time of a magnetic disk rotation, to keep the floating quantity of a magnetic head slider constant by controlling a spring pressure and to respond to a required heigh reliability and high density. CONSTITUTION:The driving voltage is supplied to an electrostrictive element 4 joined to a suspension spring 3 from a driving circuit 6 from the time when a magnetic disk 8 is stopped to the time when its rotation is accelerated, the electrostrictive element 4 is displaced in accordance with a voltage and the spring pressure of the suspension spring 3 is made small at the start and increased as a rotative speed is increased. Thus, a friction force at the time of sliding a floating head slider and the magnetic disk is made small. On the other hand, at the time of deciding a position on the rotating magnetic disk surface, the driving voltage is supplied to an electrostrictive element 5 and as the radius of a positional decision moves toward outer peripheral side, a controlling is operated so that the spring pressure of the suspension spring 3 becomes high and thus, the floating quantity from the inner periphery to the outer periphery of the disk is kept constant.

Abstract: PROBLEM TO BE SOLVED: To provide a compact unloading mat operating system of high reliability, by mounting a rack which can be engaged with a sprocket fixed on a roller shaft, and operating a support on which the rack is mounted, by an eccentric device which moves the rack to a position free from the engagement with the sprocket. SOLUTION: One of the rollers is engaged with a rail mounted in a machine during the conveying, to move a trolley to a desired inclination. When the trolley on which the baggage is loaded, is passed through an opposite part of the loading area, a controller of the machine operates an electromagnet 8, slides a cursor with a rack 13, and rotates a sprocket 14 on a shaft as a fulcrum. The shaft rotates an eccentric pin to lower a support member 17 and the rack 18, whereby the rack 18 is engaged with the sprocket 4 fixed on the shaft of the roller 3 which drives a mat. On this occasion, the roller 3 which conveys the mat, is rotated by the advancing motion of the trolley and the sprocket 4 to the rack 13, and the carried baggage is unloaded on a lower container.
