IPC: B22D17/22
Filed: 1988-06-23
Abstract: PURPOSE:To detect lack of cooling water in water passage and to prevent mass-production of deteriorated products by arranging a water passage communicating with a cooling water passage for a die in inner part of a main body and connecting a cooling water detecting means for the water passage with electric circuit for transmitting output signal to an alarm.

Title: Logical gate circuit
Inventor: UMEKI YOSHITAKA
IPC: H03K19/084
Filed: 1980-11-06
Abstract: PURPOSE:To accelerate the propagation speed and reduce the power consumption, by connecting a diode between the collector of a level shift transistor and the connector of a phase dividing transistor. CONSTITUTION:A Schottky barrier diode SBDD5 is inserted between the collector of a level shift transistor (TR)Q1 and the collector of a phase dividing TRQ2 so that the cathode of the SBDD5 is connected to the collector side of the TRQ1. When an input voltage rises from the zero level and the TRQ1 becomes the active state, a current from a power source 3 through resistances R1 and R4 is flowed as the emitter current of the TRQ1 to raise the base potential of the TR Q2. Since the value of the resistance R4 is fairly small, the base current supplied to the TRQ2 turns on the TRQ2 in an instant to accelerate the propagation speed. When the TRQ2 becomes the conduction steady state, the collector potential of the TRQ2 becomes lower than that of the TRQ1, and the current of the SBDD5 disappears.

Title: Control circuit for semiconductor device
Inventor: ONDA KENICHI
IPC: H02M7/155
Filed: 1978-12-20
Abstract: PURPOSE: To obtain a control circuit which can adapt to voltage fluctuation without using a filter, by controlling the generation of a turn-on signal by a signal obtained by averaging the output of a semiconductor device throughout the generation term of the turn-on signal.  
     CONSTITUTION: When the output level of a flip-flop circuit 9 is high, integrators 71, 72 integrate a signal produced by voltage-dividing the output of a semiconductor device and other integrators 73, 74 integrate a constant DC voltage. A divider 75 divides the outputs of the integrators 71 and 73 or 72 and 74. When the output level of the flip-flop circuit 9 is high, sample/hold circuits 716, 726 perform sampling. Values, which are sampled when the output level of the flip-flop circuit has turned low, are held by the sample/hold circuits until the output level of the flip-flop circuit turns high. The output of a switching circuit 717 or 727, which is open when the output level of the flip-flop circuit 9 is high and which is closed when the output level is low, is compared with an output set signal at 78 to apply a comparison value to a turn-on signal generation circuit 8. As a result, an average voltage determined throughout a thyristor turn-on signal can be used for control and voltage fluctuation can be adapted without using a filter.

Title: Manufacture of thin film superconductor
Inventor: ICHIKAWA HIROSHI
IPC: H01B12/06
Filed: 1987-06-24
Abstract: PURPOSE: To improve superconductive characteristic and reproductivity of a thin film by depositing oxide superconductive thin film containing an A element, a B element and Cu while applying bias on a substrate surface.  
     CONSTITUTION: While introducing gas into a vacuum vessel 14, and oxide superconductive thin film containing at least an A element, a B element and Cu is deposited on a substrate 11. Namely the superconductor is made into a thin film and further its crystal property is controlled. Since the thinning of the film makes the raw material of the superconductor decomposed into ultra-fine particles of atomic state and deposited on the substrate 11, the composition of the superconductor formed is substantially uniform. Furthermore, applying bias on the substrate 11, the amount of oxygen in the film deposited can be freely controlled and the control of crystal property becomes easy. This makes it possible to obtain a superconductor of good reproductivity and stabilized high accuracy.

Abstract: PURPOSE: To provide the developing device of a simple constitution in which a detector is not required by controlling the developing bias with the output of detection which corresponds to the electric potential of a material to be developed resulting from the exciation at a magnet brush developing device.  
     CONSTITUTION: Electric potential in proportion to the surface potential of photoreceptor 11 is excited at magnet brush developing device 12. The excited voltage corresponding to the background of electrostatic latent image of the photoreceptor 11 is detected by the voltage follower A 1  of high input resistance and memorized by the charging of capacitor C 1  via image timing switch S 1  which closes when the forward tip of the electrostatic latent image reaches the device 12. Therefore the bias voltage of the magnet brush developing device 13 is automatically controlled with the added potential resulting from the multiplication of charged potential of capacitor C 1  by the predetermined coefficient due to arithmetic circuit A 2 .

Title: Scroll type fluid machine
Inventor: HIGUCHI YORIHIDE
IPC: F04C23/00
Filed: 1991-06-27
Abstract: PURPOSE:To reduce the deflection of a stationary scroll as well as to make it simple to form an oil feed passage to a fluid operating chamber by communicating the chamber with an oil sump within a casing with each other by the use of an oil passage furnished with a squeezing section, and concurrently communicating the bottom section of the chamber with the fluid operating chamber in an intermediate pressure range by the use of an oil feed path. CONSTITUTION:A chamber 7 at the back face of a stationary scroll 2 is communicated with a high pressure oil pump 97 within a hermetic casing 1 through an oil passage 6 furnished with a section squeezed by a main bearing 5. The chamber 7 is concurrently communicated with a fluid operating chamber 4 in an intermediate pressure range through an oil feed path 70. The inner pressure of the chamber 7 is maintained at the pressure which is decreased by a decrement equivalent to the passage squeezed by the main bearing 5 against high pressure, that is, at the intermediate pressure close to pressure within the operating chamber 4, oil is thereby introduced to the chamber 7 out of the oil sump 97, so that oil is therefore fed into the operating chamber 4 from the bottom section of the chamber 7 through the oil feed path 70. In this case, since pressure at the back face side of the scroll 2 falls in the intermediate pressure range, energizing force from the back face is prevented from being excessive, deformation due to the deflection of the scroll 2 can thereby be reduced.

When an full image projected on the screen 9 is not clear, the projection lens 7 and an upper reflection mirror 8 are moved in the direction of the optical axis of the projection optical system to make a part of the image clear. When the projection lens 7 is turned by centering around one straight line on the plane perpendicular to the optical axis of the projection lens which passes the intersection of the plane perpendicular to the optical axis of the projection lens and that of the projection optical system, the full image on the screen 9 becomes clear. These actions are repeated several times, then the full clear, uniform image can be obtained on the screen 9 which is not perpendicular to the optical axis of the projection optical system.

IPC: G11B21/10
Filed: 1988-06-24
Abstract: PURPOSE:To solve a problem such as slidable contact or attraction at the time of stopping the start-up of a magnetic disk, etc., by constituting a device in such a way that a force in a direction to separate from the magnetic disk is applied on a suspension spring via a first cushioning material by deflecting a first piezo element at the time of stopping the rotation of the magnetic disk and a vacuum slider is unloaded. CONSTITUTION:A voltage is applied gradually on the piezo element 8 according to the reduction of the rotation of the magnetic disk 10 at the time of stopping the device, and the force to separate from the disk 10 is applied on the suspension spring 3 via the cushioning material 9. Therefore, the vacuum slider 1 can be unloaded just before bringing into contact slidably with the surface of the disk 10 without being brought into contact with the surface of the disk 10. By realizing such operation by using a magnetic head supporting body, it is possible to always keep a floating head slider in a non-contact state with the surface of the disk, and to evade the problem such as the slidable contact with the disk or the attraction.
