Title: Ion flow electrostatic recording type recording device
Inventor: YUASA KAZUHIRO
IPC: B41J2/415
Filed: 1985-03-28
Abstract: PURPOSE:To obtain images which are high in SN ratio and contrast by providing a bias power source which impresses a bias potential of the same polarity with ions generated by an ion generating source to a couple of electrodes of an ion flow control head. CONSTITUTION:The 2nd bias power source 36 impresses superposedly a voltage which is substantially in phase with and lower than the AC voltage of a corona generating power source 38 to both electrodes 42 and 44. Consequently, the potentials of the electrodes 42 and 44 are lowered according to the polarity of ions generated by corona discharge, i.e. when the ions are negative to reduce the inflow of ions and the potentials of the electrodes 42 and 44 are raised when the ions are positive to reduce the inflow of the positive ions. Therefore, the density of ions with which a recording member is irradiated increases and an electrostatic latent image with a high SN ratio is obtained.

Title: Speed signal generation circuit for servo circuit
Inventor: SHINOHARA TORU
IPC: G05D3/12
Filed: 1989-03-16
Abstract: PURPOSE:To prevent loop response in seek control occurring and to perform stable and fast seek even when a seek difference quantity is few by varying the band area of a speed signal generation circuit corresponding to the seek difference quantity. CONSTITUTION:The speed signal generation circuit 14A generates real speed Vr that is a servo object based on a position signal Ps from a position signal demodulation circuit. A band area variable circuit 140 varies the band area of the speed signal generation circuit 14A corresponding to the seek difference quantity. In other words, a frequency is set at the one nearer to the resonance point of the servo object when the seek difference quantity is few, and it is set at the one lower than the resonance point as increasing the seek difference quantity. Thereby, it is possible to block the occurrence of the loop resonance in the seek control regardless of the level of the seek difference quantity, and also, to perform the stable and fast seek even when the seek difference quantity is few.

Title: Drive controller for unmanned carrier
Inventor: NAGANO YUJI
IPC: G05D1/02
Filed: 1985-03-27
Abstract: PURPOSE:To attain the drive control of an unmanned carrier by controlling the drive speed of one of right and left drive wheels with the 1st drive speed signal and the drive speed of the other wheel with the 2nd drive speed signal respectively. CONSTITUTION:The 1st and 2nd drive speed signals V1(7a) and V2(7b) are obtained from the drive speed signal 1 showing the revolving speed VC and the drive speed VF of an unmanned carrier 16 respectively. These drive speed signals V1 and V2 satisfy V1>V2 from VF>O and VC>O as shown in the equations since the forward drive of the carrier 16 is shown by an arrow head VF with the speed signal 1 set at the positive value. Then the signals V1 and V2 are used to control the drive speeds of the left and right drive wheels 6a and 6b of the carrier 16 respectively. Thus the revolving speed is obtained in the direction shown by an arrow head VC.

Title: Aluminum evaporated film
Inventor: OOKUBO TOSHIO
IPC: H01L21/28
Filed: 1981-04-27
Abstract: PURPOSE:To obtain the excellent ohmic contact for an Si substrate by a method wherein an Al thin film, which was evaporated in alow vacuum condition of 5X10<-6> or above, is superposed upon the Al thin film that was evaporated at 5X10<-6> torr or below. CONSTITUTION:The film, which was evaporated in the degree of vacuum below 5X10<-6>, has large crystal grains, a flat surface and a large directivity all over. Also the above film has an excellent ohmic contact with the Si substrate, but it sometimes fails to perform a recognition function when a wiring is formed and an automatic pattern recognition is performed, because the film has a large optical directivity. The film will have fine crystal grains, a rough surface and a small directivity in optical reflection when it is formed at 5X10<-6> torr or above. However, the film is susceptible to oxidation on the surface, and the ohmic contact with the Si substrate is not as good as the former. According to this constitution, the adhesive propertiy of the film is excellent, and an Al evaporated film having no trouble in pattern recognition can be obtained.

Title: Method for driving field effect type transistor
Inventor: YOSHIDA TAKUMI
IPC: H03K17/687
Filed: 1988-03-15
Abstract: PURPOSE:To set an action delay which an FET itself has to a dead time and to improve control precision and responsibility by generating a turn-on-signal with making that the inverse bias detection element of a transistor in one arm which is serial to the other arm to non-action as a prohibition condition. CONSTITUTION:The detection elements X11, X12, X21 and X22 which operate when respective transistors 3 and 4 are inversely biased are provided, and the turn-on-signal is generated with the non-action of the detection elements X11, X12, X21 and X22 of the transistor 4 or 3 in one arm to which a gate circuit 20A or 20B that generates the turn-on/turn-off signal of the transistor 3 or 4 in the other arm is connected in serial to the other arm as the prohibition condition. Since the gate circuit 20A or 20B of the transistor 3 or 4 in one arm does not generate the turn-on signal until the inverse bias is secured between the gate sources of the transistor 3 or 4 in the other transistor, the positive and negative arms are prevented from being shortened. Furthermore, the dead time can automatically be secured by the characteristics of the transistors 3 and 4, whereby it can be shortened to the shortest possible time on circuit constitution.

Abstract: PURPOSE:To form high quality vapor-deposited films at a low degree of vacuum by continuously increasing the quantity of electric current supplied to a heating source from a low value to a desired value without generating rush current when vapor of a metal is generated with the heating source. CONSTITUTION:A vacuum chamber 1 is evacuated to about 1X10<-2>Torr by a rotary pump 4, further evacuated to about 1X10<-3>Torr by the pump 4 and a mechanical booster pump 3 and finally evacuated to about 3-4X10<-4>Torr by the pumps 4, 3 and a diffusion pump 2. Electric current is then supplied from an AC power source 10 to filaments 5 through a current regulator 9 to evaporate the metal 5 for vapor deposition and to form thin metallic films on substrates 8. At this time, the quantity of electric current supplied to the filaments 5 is continuously increased from a low value to the value required to form the films without generating rush current. Thus, no gas is emitted and vapor deposition can be carried out without causing defects.

Filed: 1978-05-25
Abstract: PURPOSE: To improve processing precision by processing the inner side of the work by means of a grindstone, moving a sliding table forward and backward and causing a main shaft table to operate eccentric rotation.  
     CONSTITUTION: Main shaft spindle 20 is rotated, and at the same time, main shaft table 13 is moved in the direction of b by means of master cam 23. Work W is rotated eccentrically along the cam lead surface of master cam 23. When rod 33 of cylinder 32 is projected under this condition, sliding table 12 moves toward the side of the grindstone table, cam-follower 36 comes into contact with slant-face cam 37, and the inner surface of work W is placed opposite grindstone 8. Next, grindstone 8 is pushed into the inner side of work W by means of a push-in device. By this, the inner side of work W is ground. Its end position determines the finished size. Consequently, operation is made smooth. Since the work is rotated eccentrically and faithfully in accordance with the shape of the master cam, processing precision is greatly increased.
