Title: Optical information recording and reproducing device
Inventor: MURAKAMI TERUO
IPC: G11B7/24079
Filed: 1981-11-16
Abstract: PURPOSE:To perform accurate tracking and to obtain a stable reproduced output signal, by setting the width of the groove and the space between the grooves larger than the width of a laser light beam for an optical recording disk having guide grooves. CONSTITUTION:The light of a laser light source 13 is detected 14 by a signal 15, and a disk 11 having guide grooves via a lens 16, polarizing beam splitter 17, lens 18, 1/4 wavelength plate 19, rotary mirror 20 and lens 21. Thus the information is recorded. In a reproduction mode, the disk 11 is irradiated by the laser light 13 passed through the same route as that used in the reproducing mode and with an output reduced less than that used in the recording mode. The reflected light given from the disk 11 is detected by a 2-split optical detector 22 via the lens 21, the mirror 20, the plate 19, the lens 18 and the splitter 17. The mirror 20 is driven 25 with the difference between the outputs 1a and 1b via a differential device 23 so as to set the difference at 0. The outputs 1a and 1b are added together 26 to obtain the output signal 27. The width of the guide groove and the space between the guide grooves is set larger than the beam width. As a result, the accurate tracking is possible and the stable output signal is obtained.

Title: Rotating device for information disk
Inventor: IWATA KAZUMI
IPC: G11B19/28
Filed: 1995-06-26
Abstract: PURPOSE: To obtain a rotating device for information disk, which is stable to the defects of the information disk and can quickly control the speed to a specified rotating speed. CONSTITUTION: The signal, which is read out of an information disk 20 wherein an RLL codes are recorded, is binarized by a waveform shaping circuit 4. A maximum-inversion-interval detecting means 5 measures the inversion interval of the output of the waveform shaping circuit 4, detects the maximum value among a plurality of obtained values and outputs the value as the maximum inversion interval. A selecting means 6 outputs the value between this maximum value and the minimum value based on the values except for the maximum value and the minimum value among three or more maximum inversion intervals outputted from the maximum-inversion-interval detecting means 5. This is a rotating device for information disk, which controls a motor for rotating the information disk in correspondence with the output of the above described selecting means.  At the time of reproduction, this device is stable to the defects of the information disk, and the access time is shortened.

Title: Flip-flop
Inventor: KATOU GIICHI
IPC: H03K3/037
Filed: 1983-09-30
Abstract: PURPOSE:To generate a Q output and a Q' output in a nearly identical timing by connecting a transfer gate and an inverter in cascade and extracting a complementary output in a D flip-flop. CONSTITUTION:When a data input D is at a high level with a clock phi of L level, a transfer gate (TG)21 is turned on and TG23, 26 are turned off. Thus, although an output of the inverter (IV)22 goes to a low level and an output of an IV25 goes to a high level, the Q and Q' outputs remain in the preceding state. When the clock phi goes to a high level, the TG21 is turned off, the TG23, 26 are turned on and the outputs Q, Q' go respectively to high and low levels. With the data input at a low level, the outputs Q, Q' go respectively to a low and a high level similarly. The state of the data input D is transferred to the outputs Q, Q' at one period of the clock and the propagation delay to the outputs Q, Q' is made identical together in this way.

Filed: 1993-07-26
Abstract: PURPOSE:To deal with change of fluid conveying condition properly an smoothly, by adjusting and setting inner pressure resistance strength of a supple pipe line part in response to the inner pressure of a force feed pipe line. CONSTITUTION:The inner pressure resistance strength of a supple and elastic duct 1 is increased in the case of fluid force feed and pressure action to the outer peripheral face of the supple and elastic duct 1 is removed in the case of fluid low pressure feed, by applying pressure which is equal or a little larger than the force feed fluid pressure, to the outer peripheral face of the supple and elastic duct 1, when the fluid is conveyed by force feed into the supple and elastic duct 1. And thus, vibration or bending displacement is absorbed by the supple and elastic duct 1, by free elastic deformation of the supply and elastic duct 1.

Abstract: PURPOSE:To reconcile reduction in free acceleration smoke and security of motive power performance by reducing a fuel injection quantity at zero-boost time in a low revolution area of an engine in a fuel injection pump having a governor having a boost compensator stopper. CONSTITUTION:When boost pressure P acting on a diaphragm 11 becomes higher, for example, than the first prescribed value P, the diaphragm 11 is pushed down, and a boost compensator spring 12 is shortened, and a connecting pin 14 coming into contact with an adjusting pin 13 opposed to a stopper 15 is moved leftward. At this time, since a tension lever 16 is pulled rightward by a governor spring 17, a boost compensator lever 18 is rotated leftward with a fulcrum A as its center. As a result, a control sleeve 19 is moved in the fuel quantity increasing leftward direction through the tension lever 16. In such constitution, a fuel injection quantity at zero-boost time in a low revolution area of an engine is reduced more than an ordinary zero-boost value.

CONSTITUTION:An alloy WTi (containing Ti of 10wt%) 20 is connected onto a GaAs semiconductor substrate 10 in Ar by a sputtering method, and processed at the temperature of 500 deg.C for 10min in the stream of NH3 diluted with N2, and thereby a nitride layer 30 of WTi alloy is prepared. The layer 30 is made thicker as the temperature is higher and as a processing time is longer. Next, Au 40 is connected onto this layer, dry etching is applied thereto sequentially with a mask, a gate electrode is prepared by removing the mask, and further source and gate electrodes 51 and 61 are provided. The Schottky reverse-direction withstand voltage of the gate electrode nitride layer/WTi alloy of Au/WTi alloy does not lower even at the temperature of 850 deg.C, and a reaction due to the diffusion of Au is prevented. Therefore, the deformation, exfoliation and disconnection of wirings do not occur at all.
