Title: Optical information reproducing device
Inventor: SHIMAMOTO MASAMI
IPC: G11B7/005
Filed: 1996-10-03
Abstract: PROBLEM TO BE SOLVED: To accurately detect an address from sector discriminating information by selecting a regenerative signal from an optimum reproducing means out of a difference signal or sum signal based on a quantitative criterion such as address detecting likelihood, etc. SOLUTION: When 1st and 2nd discriminating information areas disposed by displacing the sector discriminating information to the outer circumferential side and the inner circumferential side of a track in the radial direction as against its center at a fixed distance respectively are to be reproduced, the 1st discriminating information and the 2nd discriminating information are detected by separate detecting systems 28 and 29 respectively in a difference signal waveform shaping means 27. Thus, by detecting the 1st discriminating information, the 2nd discriminating information and user information with their individual detecting systems respectively, detecting conditions on these individual bits of information can be optimized, and as a result, detecting likelihood of the information is enhanced.

Title: Production of microencapsulated conductive filler
Inventor: DATE HITOAKI
IPC: H05K3/32
Filed: 1992-09-04
Abstract: PURPOSE:To obtain a conductive filler in a practical manner by dispersing fine conductive particles having one or more reactants on the surfaces thereof into water which may contain a reactant dissolved therein and heating the suspension or adding a catalyst thereto. CONSTITUTION:Fine conductive particles which have on the surfaces thereof either a solvent and a reactant (A) or the reactant (A) alone are dispersed as an oil phase into water containing a reactant (B) reactive with the reactant (A). Alternately, fine conductive particles which have on the surfaces thereof either a solvent and at least one reactant or at least one reactant alone are dispersed as an oil phase into water. The resulting suspension is heated or a catalyst is added thereto to thereby react the reactant(s) on the particle surfaces.

Title: Method of thrusting up pellet
Inventor: UCHIHASHI HAJIME
IPC: H01L21/68
Filed: 1988-10-21
Abstract: PURPOSE:To pick up a pellet smoothly from a table even though the rear of its pellet is treated by a three dimensional process by causing a thrust-up plate to be formed into a slit like plate and thrusting up its thrust-up plate after positioning the pointed end edge of the thrust-up plate on the bisector at the rear of the pellet. CONSTITUTION:A knife-edge-like edge 3a is formed at the pointed end of a thrust-up plate 3. The position of the thrust-up plate 3 to a pellet 1 is established so that the edge 3a agrees with a line on the transversal (or longitudinal) bisector of the pellet 1 in a state that is edge line passes over a recessed part 1b; besides, the thrust-up plate 3 is kept in a position that is vertical to the pellet 1. If the thrust-up plate 3 keeps on pushing up from this position, its plate 3 makes a tape 2 throw out upwards in a state that only the pointed end edge line 3a comes into contact with the tape 2. As a result, the tape 2 is peeled off gradually from the rear of the pellet 1 with the exception of a contact part between the tape 2 and the edge 3a with the pushing up of thrust-up plate 3. In this way, the pellet 1 is peeled off smoothly from the table 2 without damaging a pressure sensitive part 1a on the recessed part 1b of the pellet 1.

Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To restrain the effects of noises emitted from a digital signal processing circuit so as to improve a semiconductor integrated circuit in reception sensitivity by a method, wherein an analog circuit that deals with signals of highest frequencies is arranged between a circuit that deals with large analog signals and a digital circuit. SOLUTION: A second mixer circuit, that deals with smallest signals of highest frequency, is arranged farthest from a digital signal processing circuit compared to other circuits, so as to lessen the effects of digital signals and to mount an analog circuit and the digital signal processing circuit are formed on the same board. Input/output pads, a power supply terminal, and a grounding terminal for an analog circuit are arranged farthest from a power supply terminal and a grounding terminal for a digital signal processing circuit. For instance, they are diagonally arranged, whereby the effects of noises can be reduced. Furthermore, a bias generating circuit is arranged between a limiting amplifier and a digital signal processing circuit which functions as a guard band that causes noises to attenuate.  With this setup, a digital/analog integrated circuit which takes into consideration the propagation characteristics of noises can be obtained.

Title: Microprocessor system with cache memory
Inventor: SATO KAZUYUKI
IPC: G06F12/08
Filed: 1986-11-06
Abstract: PURPOSE:To eliminate a program interchanging problem with a microprocessor containing a cache memory by carrying out initialization of a directory by hardware instead of software before a program is executed. CONSTITUTION:When the reset signal received from outside via an initialization control circuit 6 is set active, a memory bus control circuit 5 acquires a bus by sending a HOLD signal to a microprocessor 1. The processor 1 receives a HOLD request before the first instruction is fetched after release of the reset signal and releases the bus to send a bus acquisition approving signal HLDA to the circuit 5. The circuit 5 receives the signal HLDA after a reset state and delivers data 0 to an address bus to sends and write a cache directory writing signal CDWE to a cache directory 4. Then the addresses are successively replaced up to 4, 8...FFFC and initialization is carried out with all cache directory areas.

Filed: 1986-11-10
Abstract: PURPOSE:To minimize the scale of a page table by adding the number of valid pages as well as a flag showing whether said number of valid pages is received from the head or the end of a segment into a segment table and converting a virtual address into a read address in accordance with said flag. CONSTITUTION:The segment information on a segment number 1023 is selected out of a segment table 30 by a number 106-1. Then a valid flag of the segment information is checked to decide the head address of a corresponding page table 40-2. Then it is decided from a number 102-5 that the table 40-2 is set at and after the end of the relevant segment together with reference given to the value 254 of a page number 106-2 in a virtual address. Thus a page of the table 40-2 is decided. Thus a page number 104-1 of a main memory is decided and the value q1 of the number 104-1 is multiplied by the number of bytes per page. Then a virtual memory address 106-3 is added to the result of said multiplication to obtain the final main memory address.
