Title: Nanufacture for semiconductor device
Inventor: SATOU SHIGERU
IPC: H01L21/322
Filed: 1977-09-16
Abstract: PURPOSE: To block the intrusion of phosphorus by avoiding the reduction in Si 3 N 4  film in the manufacturing process, through the deposition of polycrystal Si or low temperature oxide film after depositing Si 3 N 4  film at the opposing surface of the element forming surface.  
     CONSTITUTION: Oxide film 13 and nitride film 14 are overlaid on the front and rear surface of the P type Si substrate 12. CVD SiO 2  is deposited on the both sides and field oxide film is made by opening with etching, removing all SiO 2  at the rear side. Next, polysilicon 17 is deposited with reduced pressure CVD method, electrodes 18a to c are formed on the layer 17a with phosphorus diffusion and they are covered with the oxide film 19. Similarly, the polycrystal silicon 20 is deposited, electrodes 21a and 21b are selectively formed by performing phosphorus diffusion on the layer 20a, and they are covered with oxide film 22. The layer 20b is removed after phosphorus diffusion. SiO 2  23 is deposited on the oxide film 22, and after removing the films 14 and 13 at the rear side of the substrate, CCD is constituted with phosphorus getter. Thus, the next process is proceeded without etching Si 3 N 4  at the rear side and the intrusion of phosphorus on the way can be avoided.

Title: High speed copying apparatus
Inventor: KUBO KIKUO
IPC: G03B27/00
Filed: 1977-09-14
Abstract: PURPOSE:To simultaneously produce a plurality of hard copies in a single scanning operation of an original by providing a plurality of writing sections. CONSTITUTION:A reading section 1 reads out the optical image signals S1, which are detected by scanning an original with an optical system, and converts them into electric image signals S2. A signal treating section 2 amplifies the image signals S2 so that they may be processed in a sample AND holding operation or in a converting operation into logic signals. Writing drive sections 3(31 to 3m) reform the processed electric signals such that they are suitable for subsequent writing sections 4(41 to 4n) so as to generate their drive signals. A control section 5 partly controls the operations of the components 1 to 3 in accordance with the outside control signals S3 following the command of an operator and partly monitors the operating conditions of the components 1 to 3 so that the control may be performed to maintain the most proper condition at all times.

Title: Control device for vehicle provided with automatic transmission
Inventor: KASHIWABARA MASUO
IPC: F16H63/50
Filed: 1994-05-25
Abstract: PURPOSE:To keep a driver from feeling uncomfortable by providing a means for inhibiting speed change to a low speed stage at the time of detecting a specific condition, and a means for judging the start of a vehicle, and increasing the torque of an engine at the start time of the vehicle in the inhibited state of speed change to the low speed stage. CONSTITUTION:Under a specific condition, that is, upon judging congestion, a control unit 50 inhibits speed change control based on a normal travel pattern and changes to a pattern of traveling at a small gear ratio preventing sudden start and the frequent generation of speed change shock by reducing the frequency of speed change. The control unit 50 controls the opening of an ISC valve 21 at the start time in the inhibited state of speed change to the first gear speed so as to increase intake air quantity Qa to increase driving force. This constitution can reduce the possibility of making a driver feel uncomfortable at the start time after judging congestion, that is, the generation of discomfort to the driver due to the shortage of driving force can be prevented while preventing overaccelerated, start in congested travel and frequent speed change after the start.

Title: Electronically controlled suspension device
Inventor: TAKEI FUMIAKI
IPC: B60G17/015
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To improve riding comfortability stability of a vehicle body attitude, and durability by quickly softening the damping force of hydraulic shock absorber and softening the spring constant of air springs after a prescribed time elapse. SOLUTION: When the relation between the direction of lateral acceleration and the steering direction is abnormal or the absolute value of the lateral acceleration becomes smaller than a prescribed value, a roll control is stopped. Then, while the damping force of hydraulic shock absorber 10 of the whole wheels is quickly switched to the soft, the spring constant of air springs 5 of the whole wheel is switched to the soft with a prescribed time delay. Namely, the damping force of the hydraulic shock absorber 10 is quickly softened, a prescribed time is counted by a timer, the spring constant of the air spring 5 is softened after the time is up, and the roll control mode is released. This constitution can improve the riding quality, the stability of a vehicle body attitude, and the durability.

Title: Work vehicle
Inventor: MORITA SAICHIRO
IPC: B62D55/12
Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To prevent the deposit of mud earth on a crawler belt while mud earth adheres on it by providing a crawler belt wound around front and rear driven wheels and a drive wheel and a rolling wheel guiding a lower turn side part of the crawler belt and arranging the drive wheel close to the rear driven wheel rather than the front driven wheel. SOLUTION: A drive wheel 15 is arranged at a more rearward position than a central position between front and rear driven wheels 11 and 13 and is arranged close to the rear driven wheel 13. Consequently, a width between front and rear parts of an upper turn side part of a crawler belt 16 positioned between the front driven wheel 11 and the drive wheel 15 becomes large, and as a result, the upper turn side part vibrates properly due to the vibration of a vehicle body to shake off the mud earth adhered on the upper turn side part and prevent the deposit of the mud earth on the crawler belt, thereby preventing coming off of the crawler belt by the deposited mud earth. Furthermore, a front side of the crawler belt 16 wound into a triangular shape can be formed into an acute angle when viewed from side.

Abstract: PURPOSE: To make it possible to obtain a measured value with high precision under no influence of thermal contraction of an insulating solution due to variation in ambient temperature, by forming either one of diaphragms of a conventional pressure measuring instrument in a wave shape.  
     CONSTITUTION: One external cylinder 24 with bottom 22 is equipped with diaphragm pedestal 29 and pipe 48, and the other with cradle plate 48 and wave- shaped 46, the both are hermetically sealed by welding. Diaphragm 30, insulator 35 and reference electrode plate 40 are pushed through plate spring 41. Insulator 35 has electrodes 32A and 32B of metal foil and electrodes, diaphragm 30 and reference electrode plate 40 are held at fixed intervals. Pressure to be measured operates on the both diaphragms through a through hole and insulating solution filling external cylinder 24. From variation in capacitor value between pressure measuring diaphragm 30 and electrode 32A, a difference in pressure between the right and left can be obtained, and force pulling diaphragm 30 in its radius direction never changes. Through the operation of wave-shaped diaphragm 46, no measured-value error is caused by variation in temperature.

Filed: 1986-05-15
Abstract: PURPOSE:To securely separate an optical path by a dichroic mirror by forming the 2nd light source having light wavelength different from the light wavelength of the 1st light source. CONSTITUTION:The light wavelength of the light beam 102 of the 1st light source 101 is so set that the light beam is reflected by the dichroic mirror 105; and the light wavelength of the light beam 111 of the 2nd light source 110 is so set that the light beam is transmitted through the dichroic mirror 105. The light wavelength of the light beam 102 of the 1st light source 101 and the light wavelength of the light beam 111 of the 2nd light source 110 overlap with each other at the time of information recording, but the light beam 102 of the 1st light source 101 is reflected by the dichroic mirror 105 and the light beam 111 of the 2nd light source 110 is transmitted through the dichroic mirror 105, so both light beams are utilized effectively. Even if the light beam 111 of the 2nd light source 110 is relatively small at the time of information reading operation, effective read information is obtained without any loss.
