Title: Composite lens plate for displaying three-dimensional video
Inventor: HAMAZAKI JOJI
IPC: H04N13/04
Filed: 1988-02-24
Abstract: PURPOSE:To simplify a structure and to reduce the loss of light quantity and the limit of visible area by composing a horizontal direction image-formation lens plate having a periodic curvature in a horizontal direction, a shield grid having early same period as the image- formation lens plate in a horizontal plane and a three-dimensional video reproduction lens plate having a periodic curvature in a horizontal direction. CONSTITUTION:The horizontal direction image-formation lens plate 2 has the curvature only in the horizontal direction and its focal distance and a distance D between the back surface of the three-dimensional video reproducing lens plate 4 and said lens plate 2 are selected so that a line image group on the back surface of a protective glass plate 1 can be formed in the horizontal direction on the back surface of the three-dimensional video reproducing lens plate 4 in nearly equal magnification. Supposing that the fine line image group turning to a vertical direction, obtained by making N lines drawn on the back surface of the protective glass plate 1 as one set is an object, the position, the form and the dimension of the shield grid 3 are fixed so that light beams emitted from the line image group are made to arrive at only back surface of one element lens of the three-dimensional video reproducing lens plate 4 which exists in front of the line image group. Since the curvature of the horizontal direction image-formation lens plate 2 is limited in the horizontal direction and the shield grid 3 is a vertical grid group, the structure is simplified and the loss of the light quantity can be reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device which enables miniaturization and adjustment of resistance value with high precision, and manufacture thereof. SOLUTION: An impurity diffusion layer 2 is formed on the surface of a single crystal silicon substrate 1, and a silicon oxide film 3 as an interlayer insulating film is deposited by a plasma CVD method or the like on the impurity diffusion layer 2 and on a plane of the single crystal silicon substrate 1 where the impurity diffusion layer 2 is formed. A contact hole 4 is formed in the silicon oxide film 3 on the impurity diffusion layer 2 by photolithography and etching techniques, and a wiring layer 5 is formed in the contact hole 4. Thus, a resistance element is manufactured. In this case, the impurity diffusion layer 2 is formed to have an impurity density gradient such that the impurity density near the surface increases with respect to the direction of depth, by adjusting the implantation energy in ion implantation.  Then, the resistance value is increased by performing laser trimming on the impurity diffusion layer 2 in such a manner as to break the current path with respect to the direction of depth. Thus, the resistance value is adjusted.

Abstract: PROBLEM TO BE SOLVED: To detect atmospheric pressure and rightly correct a target injection rate in association with detection of the atmospheric pressure by judging EGR non-execution in a condition in which a value detected by a negative pressure sensor is a prescribed atmospheric pressure corresponding value, when non- execution of an EGR is decided, or while a non-execution command signal is outputted. SOLUTION: In an EGR judging unit 6 for inputting rotating speed NE, a final target injection rate Qdsr, and intake negative pressure Pv, it is judged whether it is in an operating condition for executing the EGR or not. When it is in an EGR executing region, intake negative pressure PV is memorized in a memory as EGR negative pressure, and a flag showing execution of EGR is set. On the other hand, the intake negative pressure Pv is compared with a prescribed value corresponding to the atmosphere in an EGR non-execution region, the detected value Pv is memorized as the atmosphere when the intake negative pressure Pv is the prescribed value and less, and also the flag showing execution of the EGR is reset. When the detected value Pv is the prescribed value or more, a main routine is completed without renewing the EGR negative pressure and the atmosphere.

Title: Oscillation control device for railway rolling stock
Inventor: UCHIYAMA MASAAKI
IPC: B61F5/24
Filed: 1996-02-05
Abstract: PROBLEM TO BE SOLVED: To attempt proper oscillation restraint by carrying out control of a sky-hook theory without using a damper speed sensor. SOLUTION: A damping coefficient indication signal is output to a proportional solenoid 16 of a damper 8 by correcting a target damping coefficient by dividing a speed data V corresponding to the target damping coefficient by acceleration J for division corresponding to acceleration α. As a damping coefficient of the damper 8 is in inverse proportion to damper speed against a damping coefficient of a sky-hook damper and the damper speed is roughly in proportion to the car body cross acceleration α, that is, to the acceleration J for division, it is possible to compute the damping coefficient of the damper 8 by using the acceleration J for division, to constitute the sky-hook damper and to maintain a favourable damping property. Additionally, as the favourable damping property can be secured without using a damper speed sensor, cost increase of a device is not caused and maintainability is neither spoiled.

IPC: H04J3/17
Filed: 1981-03-23
Abstract: PURPOSE:To perform call and data communication simultaneously without interrupting voice communication by providing a multiplexer between a digital vocoder and an MODEM and communicating data between synchronous data terminals. CONSTITUTION:A voice signal is converted into a framed digital data by a digital vocoder 3. When detecting a specific code indicating no call or no voice in calling from a frame sent from the vocoder 3, the transmitting part of a multiplexer 1 replaces the spectrum information of the frame with a data from a synchronous data terminal 5. Then the transmitting part transmits the replaced data to the receiving part of a multiplexer 2 through an MODEM8, a transmission line 7 and an MODEM9 in the opposite side. When detecting the specific code,  the receiving part of the multiplexer 2 interprets that the transmitting part of  the multiplexer 1 has inserted the spectrum information data and sends the signal to a synchronous data terminal 6.
