Filed: 1986-07-01
Abstract: PURPOSE:To obtain a UVPROM-type semiconductor device of stable quality by shifting a center position of an ultraviolet transmitting glass window attached to a lid plate of insulator. CONSTITUTION:An ultraviolet erasable programmable read-only memory (UVPROM) has an ultraviolet transmitting window provided at a lid member of its package the center of the ultraviolet transmitting window of the lid member is deviated horizontally from the center of the semiconductor element in an insulating base substance. For instance, when a semiconductor element 3 bonded in a cavity 2 located in a cavity 2 located in the center of insulating base substrate 1 is sealed with the lid member 5 in such a manner that the window 7 in the lid member has an outer edge portion coincident with the circumference of the semiconductor element. The center C2 of the window is deviated from the center C1 of semiconductor element 3 by d in the transverse direction. In the same manner, the ultraviolet penetrating glass window 7 is installed on the lid plate 6 with the deviation from the center of lid plate. It is desirable that the deviation (d) is smaller than the diameter of the ultraviolet transmitting glass window.

Abstract: PURPOSE:To prevent the contact sliding or attraction between a slider and a disk by providing a piezo-element and a cushioning material, which arrive at the central part of a suspension spring, through an insulating material on the negative pressure slider existing side of a suspension spring rear edge part. CONSTITUTION:After a spindle starts rotation and the disk arrives at a stationary speed, when a voltage is impressed on a piezo-element 5, the tip of the piezo-element 5 generates displacement in a direction separate from a suspension spring 3, and when the already bent spring 3 approaches to a flat condition, a negative pressure slider 1 coupled through a gimbal spring 2 with the tip approaches the surface of a disk 7. The interval between the surface of the disk 7 and the sliding surface of the negative pressure slider 1 amounts to several tens microns, a self-loading operation is generated in the negative slider 1, and the negative slider 1 is smoothly loaded on the disk 7. Further, when the piezo-element 5 is bent, the cushioning material 6 is completely separated from the spring 3, and the piezo-element 5 does not affect the spring 3 at all.

IPC: H04J14/02
Filed: 1998-06-04
Abstract: PROBLEM TO BE SOLVED: To transmit a sub-signal by a simple structure without affecting the bit rate of a main signal. SOLUTION: An electrical-to-optical transducer 1 performs electrical-to-optical conversion of a main signal D1. A temperature control circuit 3 controls a transmission center wavelength of a filter 2 by changing the temperature of a wavelength variable filter 2 in accordance with a sub-signal D2. An optical signal that is outputted from the wavelength variable filter 2 becomes the one in which an amplitude component of the main signal is multiplexed by the sub-signal. An optical-to-electrical transducer 5 carries out optical-to-electrical conversion of an optical signal received from an optical transmission line 4. A discrimination reproduction circuit 7 reproduces the main signal D1 from an output signal of an equivalent amplifier circuit 6 and a discrimination reproducing circuit 9 reproduces the sub-signal D2 from the output signal of an envelope detection circuit 8.

Title: Photo mask blank substrate
Inventor: ITOU MASAKI
IPC: G03F1/58
Filed: 1977-12-23
Abstract: PURPOSE: To eliminate charging-up at the time of electron-beam exposure by using a photo mask blank substrate which has a support plate coated with a conductive  substance and then with an insulating and shielding substance except one part.  
     CONSTITUTION: Glass support plate 1 is coated with conductive substance 2 of chromium, etc., and then covered with insulating and shielding layer 3 of metal oxide, silicon, etc., with one part of layer 2 exposed, thereby obtaining a photo mask blank substrate. This substrate is applied with electron-beam resist 5 and after charge eliminating contact terminal 7 is made in contact with exposed part 4 of the conductive substance, the substrate is irradiated with electron beam 6. Since irradiated electrons propagates in conductive substance 2 and escape from exposed part 4 through charge eliminating contact terminal 7, the charging-up of the substrate is eliminated, so that a fine pattern can be formed.

Title: Logic circuit
Inventor: AKITA YOHEI
IPC: H03K17/693
Filed: 1999-06-03
Abstract: PROBLEM TO BE SOLVED: To obtain a logic circuit that has the same delay time as that of a conventional logic circuit and acts like a D flip-flop circuit DFF. SOLUTION: Each data propagation path from an input terminal I1 (I2) to an output terminal O1 consists of two transmission gates TG10a (TG10b), TG11 and two inverters IV10, IV11 consisting of 4 logic gates as the path similarly to the case with a conventional DFF. An NOR12a receiving a clock CLK and an inverse of selection signal/sel (an NOR12b receiving a clock CLK and a selection signal sel) controls the TG10a (TG10b) and the CLK controls the TG11. The selection signal is used to select either of two input data and to provide an output of the selected data. Thus, a pipeline circuit is operated at a high-speed by using the Dff having a data selection function for the pipeline circuit in,spite of the same delay time.

Title: Refreshing system
Inventor: NISHIYAMA KAZUHIDE
IPC: G11C11/34
Filed: 1986-07-04
Abstract: PURPOSE:To improve the efficiency of an MPU operation by refreshing only the operating area of a memory device. CONSTITUTION:A memory 7 consists of a number of DRAMs decided by a data width of an MPU 1 and includes the unoperating area of the total capacity. A data representing the operating area of the memory 7 is stored in a refresh controller 3 by the MPU 1 and outputs a counter control signal CC in response thereto and a refresh control signal CR bringing the memory 7 into the refresh state. When a timing signal T from a timer 2 goes to 1, a counter 4 is incremented by 1 and the count becomes, e.g., N. Further, a switch 6 receives the signal CR and outputs a memory control signal CM to the memory 7 and a switch 5 receives a refresh address signal AR of the count N of the counter 4 and outputs the memory address signal AM to the memory 7. Thus, the row address N of the memory 7 is refreshed during T=1. The switches 5, 6 are switched at T=0 to complete the refresh. In repeating the processings above, the entire operating area of the memory 7 is refreshed.

IPC: G01L1/16
Filed: 1999-06-03
Abstract: PROBLEM TO BE SOLVED: To provide a catching detector having high detection accuracy and an opening/closing apparatus. SOLUTION: A flexible stripe piezoelectric sensor 6 is supported by an window frame 4 at a supporting part 10 in the widthwise direction thereof. When the piezoelectric sensor 6 touches an object M, an abutting part 11 is deformed flexibly and since a widthwise flexure is imparted in addition to a longitudinal flexure, a large deformation is produced and the output signal from the piezoelectric sensor 6 is increased. Since the signal component of catching can be discriminated easily from the signal component of external vibration or electric noise, detection accuracy can be enhanced.

Inventor: MURATA MINEO
IPC: H01L21/822
Filed: 1989-06-19
Abstract: PURPOSE:To obtain element isolation, wherein substrate surface is flat and internal stress is small and also lateral expansion of element isolation width is small, excellently in reproducibility by growing polysilicon so as to bury a trench formed on a semiconductor substrate, and then removing the polysilicon from the surface of the substrate by polishing, and successively oxidizing the substrate thermally. CONSTITUTION:A trench formed at the surface of a semiconductor substrate 1 is buried by growing polysilicon, and after growth of polysilicon, the polysilicon 5a is removed from the surface of the semiconductor substrate by polishing, and then the semiconductor substrate 1 is thermally oxidizing. That is, since the polishing method is used, even if there is a step at the surface of the polysilicon 5a before polishing, it does not matter, so the film thickness of polysilicon for embedding the trench can be thinned more than before, consequently it becomes possible to shorten the growth time of polysilicon. Further, since the surface is flat, the thickness of an oxide film 4b at the surface of the polysilicon 5 inside the trench can also be thinned. Hereby, it becomes enough with the oxidation at low temperature and in a short time, and the decrease of stress inside the trench and the lateral expansion of element isolation width attendant upon oxidation become possible, and the element isolation, where a trench is used, can be obtained excellently in reproducibility.
