Title: Piezoelectric actuator
Inventor: TSURUGA TAKAHIRO
IPC: H01L41/09
Filed: 1989-02-06
Abstract: PURPOSE:To suppress increase of temperature of a piezoelectric actuator and to improve its reliability against temperature by providing electrode disks with radiating sections which are projected out beyond the periphery of piezoelectric bodies. CONSTITUTION:Columnar piezoelectric bodies 3 and electrode disks 4 are put one over another alternately. The electrode disks 4 are wider than the piezoelectric bodies 3 and a radiating section 4a is provided along the circumference of each of the electrode disks 4. Namely, the electrode disks 4 have the radiating sections 4a projected out beyond the periphery of the piezoelectric bodies. Therefore, configurations, size and arrangement of the radiating sections 4a are dependent on service conditions, etc., of the piezoelectric actuator. Heat generated within the piezoelectric bodies 3 is conducted to the electrode disks 4 and radiated by the radiating sections 4a of the electrode disks 4. According to this arrangement, increase of temperature in the piezoelectric actuator can be suppressed and reliability against temperature of the piezoelectric actuator can be improved.

Abstract: PURPOSE:To obtain the IGFET which consumes less power by providing a source region having the same conductive type as that of a drain region in a semiconductor substrate which is to become a drain region, and providing a control electrode surrounded by a gate electrodes on the surface therebetween. CONSTITUTION:The substrate 3 which is to become the drain region is constituted by an N<+> type semiconductor layer 2, which is located at the lower side, and an N<-> type layer 1 thereon.

Title: Information signal recording disc and its recording system
Inventor: TAKAHASHI NOBUAKI
IPC: G11B21/12
Filed: 1981-02-26
Abstract: PURPOSE: To control the moving speed of a reproducing element for pickup reproduction of a recording signal with the same circuit, by recording a burst signal in a frequeny other than that of a main information signal band through the selection of recording length at each revolution of a disc.  
     CONSTITUTION: A static capacitance formed between an electrode of a reproducing stylus 31 and a disc 29 is converted into a high frequency with a pickup circuit, and the signal is applied to a demodulation circuit 33, band pass filters 34 and 35, and an fp 3  detector 36 respectively. An output detecting signal FP 3  of the detector 36 is applied to an fp 3  length detecting circuit 41, where the burst length at a disc rotation period of the fp 3  detecting signal FP 3  reproduced is detected. In this case, since the burst signal is recorded by selecting the recording length at each rotation of a disc, the moving speed of a reproducing element to pick up and reproduce the recording signal can be controlled with the same circuit, to achieve low cost.

Title: Sheet lap delivery prevention device and sheet look stand
Inventor: TOGAMI MOTOYOSHI
IPC: G06K13/103
Filed: 1988-02-10
Abstract: PURPOSE:To make it possible to prevent lap delivery in conformity with sheets by mounting a plate near to the end part of the delivery side of a support stand, making the plate to unsliding, and composing the captioned device so that the adjustment of the inclination angle facing in the oblique direction to the plate surface of the support stand is made possible. CONSTITUTION:When sheets 2 are delivered in order as required from a plate 3 where the sheets 2 of plural sheets of cutforms and manuscript notes and the like are lapped, if two or more sheets 2 are concurrently delivered, the sheets other than the uppermost sheet 2a stop at an inclination part since the slide between the sheet 2 delivered with the seat 2a and the inclined part composed of a stopper part 10 to which an unsliding film 10a is sticked is worse than that between the uppermost sheet 2a and the sheet 2 delivered with the sheet 2a. Also the adjustment of an incline angle is necessary depending on a paper material, and the incline angle of a thick paper is made to gentle, and that of a thin paper to steep. Thus lap delivery in conformity with the sheet 2 can be prevented.

Title: Fault detector for secondary circuit in wound-rotor type induction motor
Inventor: MINETOMO KIYOHIRO
IPC: G01R31/34
Filed: 1981-02-26
Abstract: PURPOSE:To reduce the cost of a wound-rotor type induction motor and to simplify the insulator between a secondary circuit and a secondary circuit fault detector by employing a current transformer for detecting the secondary current of the motor. CONSTITUTION:A signal proportional to the secondary current of a wound- rotor type induction motor 1 in each phase is produced by a current transformer 10, and the signal is rectified and smoothed via a peak value detection type rectifying and smoothing circuit 11. Since the production of the secondary current with the transformer 10 is not performed by a conductor connection such as a shunt, but is performed by the connection of the terminal to the terminal, the insulator between the terminals can be simply formed. The output of the circuit 11 is compared by a comparator 6, and when either one of the outputs of the comparator 6 becomes at least higher than the prescribed value, a relay 8 is operated.

     SOLUTION: In a sputtering chamber 100, the magnetic field formed of a heart-shaped magnet assembly 110 composed of a permanent magnet 112 is confined by a backing magnet assembly 124. By this magnetron assembly 108, a plasma generating region 134 is formed on a target 116 to generate plasma, and sputtering is executed. In this way, as for sputtering atoms generated from the target 116, the orbit thereof is corrected by a collimator assembly 122, and they are introduced into a wafer substrate 120 and are deposited thereon to form a thin film. At this time, a plasma gas 132 such as Ar 126 is directly fed to the above plasma generating region 134. Thus, the collision between the sputtering atoms and the plasma gas is suppressed to prolong the free stroke thereof.
