Title: Self-hold type gas shut-off valve
Inventor: NUKUI KAZUMITSU
IPC: F16K31/06
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To change a shape of an attracted piece into a simple shape having no stepped structure so as to reduce cost. SOLUTION: A diameter of a permanent magnet 1A is substantially same as an inside diameter of an expanded section 121A of a seal pipe 12A, and instead, a shape of an attracted piece 5A is like a bar simply. Consequently, the travel of a first seal packing 14 in the axial direction is prevented by the permanent magnet IA to prevent coming off of it. The shape of the attracted piece 5A facilitates machining when compared with conventional stepped attracted piece so that machining cost is reduced.

Title: Fpc/ffc connector
Inventor: AOKI KAZUNORI
IPC: H01R12/79
Filed: 1999-07-26
Abstract: PROBLEM TO BE SOLVED: To reduce crosstalk between adjacent signal contacts by installing a pair of tabular earth members arranged in almost parallel each other, between which many signal contact groups are interposed. SOLUTION: When many signal contacts 20 are positioned between an earth surface 13a and a metal plating layer 41 arranged in parallel, an electromagnetic bonding value or electrostatic bonding value between adjacent contacts 20 is made small and crosstalk is made small. Distance between the earth surface 13a and the metal plating layer 41 arranged in parallel, or characteristic impedance between the signal contacts 20 and the earth surface 13a, and between the signal contacts 20 and the metal plating layer 41 is desirable to match with the characteristic impedance of an FPC/FFC.  Especially, by forming the metal plating layer 41 to be earthed on the surface of a slider 40, the distance between the earth surface 13a and the signal contacts 20 and between the metal plating layer 41 and the signal contacts 20 or materials of them are adjusted so as to match with the characteristic impedance of the FPC/FFC, and crosstalk can effectively be reduced.

Filed: 1987-08-25
Abstract: PURPOSE:To make a semiconductor substrate to have a high depression effect for slippage line and a strong gettering effect, by depositing a polycrystalline silicon on the rear of a single crystalline silicon substrate in which the oxygen concentration thereof is so controlled as to less than a specific value. CONSTITUTION:A single crystalline silicon substrate 11 with low oxygen concentration is produced using a CZ method in which the oxygen concentration thereof is so controlled as to be less than 14X10<17>atoms/cm<3>.

Title: Compression and expansion method for computer data
Inventor: YAMAMOTO TAKESHI
IPC: G06F5/00
Filed: 1995-08-18
Abstract: PROBLEM TO BE SOLVED: To improve the data compression rate and the data compression processing efficiency by applying compression processing to different records so as to compress same character strings and applying compression processing to consecutive character strings in same records. SOLUTION: The method includes a step of 1st compression processing compressing same character strings between different records and a step for a 2nd compression processing compressing consecutive character strings in same records. In the case of compression processing, the compression processing is requested by designating an acceptance code C1 for consecutive character compression processing and inter-record compression processing and data C5 to be compressed depending on a data characteristic. Thus, in addition to the consecutive character compression processing in a conventional same record, same characters are compressed between different records and the both processing methods are combined to considerably enhance the compression rate of computer data.

Abstract: PURPOSE:To prevent a separation belt from forming a separation black line by slanting the folded and overlaped separation belt in the contact area of a drum to a narrow width in its downstream rotation direction, and making its upper stage narrower than the lower stage. CONSTITUTION:The folding part of the folded and overlaped separation belt 3 is hooked to a pin 4 and the other terminal is clamped with a holding piece to extend the belt, and recording paper 7 is conveyed as shown by an arrow (a) in contact with the outer circumferential surface of the drum 1. The belt 3 has edges 3a and 3b which slant decreasing in width gradually toward the downstream side in the drum rotating direction in the contact area L with the drum 1, and the slanting edges forms a step while the side 3a contacting the recording paper 7 is wider than the side 3a contacting the drum 1. Therefore, toner is scraped and collected with the narrow side 3a and toner overflowing the end part is received by the wide side 3b and prevented from sticking on the recording paper 7, so the formation of a separation black line is prevented.

Title: Piezoelectric vibrator
Inventor: YAMADA SUMIO
IPC: H03H9/17
Filed: 1988-08-25
Abstract: PURPOSE:To obtain high performance by setting slip vibration to be one wave length displacement by specifying W/H when the thickness of a pole piezoelectric body in a segmented angle form, where a polarized inversion layer is generated in a vertical thickness direction with respect to a specified confronting main surface, in which an electrode is generated, to be H, and a width to be W. CONSTITUTION:In the piezoelectric vibrator 1 of a strip type, the segment surface of a 163 + or -15 degrees rotary Y plate consisting of a ninobic acid lithium single crystal is set to be the confronting surface. When the thickness vertical to the confronting surface is set to H, a length to L and the width to W, the piezoelectric body 2 is generated so that W/H shows 1.0-1.7 or 2.0-2.7. The piezoelectric body 2 generates a polarization Ps by a boring processing before the rotary Y plate is segmented from the single crystal and an inversion polarization Ps' by the generation of the polarized inversion layer 5. Thus, the thickness slip vibration which occurs by impressing the appropriate high frequency field on the electrodes 3 and 4 shows one wave length displacement. Consequently, a stable element superior in the vibration characteristic can be supplied.

Title: Method of variable speed control of motor
Inventor: TEJIMA MITSUNORI
IPC: H02P29/00
Filed: 1987-08-27
Abstract: PURPOSE:To control a motor stably for variable speed, by serially compensating a motor variable speed control system, using each finite time settling controller corresponding to the target value variation and disturbance from an impulse response of the motor variable speed control system. CONSTITUTION:Since the input series of a controller Dr(Z) to make a controlled value respond in finite time settlement to a target value will be E(Z) expressed as a formula I and its output series will be U(Z) expressed as a formula II, the controller Dr(Z) will be expressed as a formula III. On the other, the input series of a controller Dd(Z) to make a controlled value respond to a disturbance in finite time settlement will be X'(Z) expressed as a formula IV and its output series will be U'(Z) expressed as a formula V. The controller Dd(Z) will therefore be expressed as a formula VI. Consequently, using serial compensation controllers Dr(Z) and Dd(Z) as given by formulae III and VI, the optimum finite time settling response controller can be obtained. Application of this controller to the variable speed control device of a motor 4 will find a finite time settling response to both the target value (speed reference) and disturbance (load torque).

Filed: 1993-08-26
Abstract: PURPOSE:To miniaturize an OHP device and to make set space small by reducing and recording an original in a main body and copying the recorded reduced image on a transparent film. CONSTITUTION:The optical system of the coying part of this OHP device is set so as to scan an original image under an original platen 24. The optical system is constituted of a light source, mirrors 18 and 19, and a projection lens 10. The original image passes through the respective mirrors 18 and 19 and reaches a photoreceptor drum 16. Since the original image is reduced by the projection lens 10 at this time, the small-sized photoreceptor drum may be used. The original image recorded on the drum 16 is copied on the transparent film 15 by an electronic system copying means, whereby an OHP film is formed. The width of this film is smaller than that of the original platen 24 because the original is reduced and copied, so that the device is miniaturized. The original image on the film 15 is projected to a screen by a projection part set on the downstream side of the drum 16.
