Filed: 1985-07-29
Abstract: PURPOSE:To improve nodular corrosion resistance without damaging strength, ductility, etc., of Zr alloy, by suppressing carbon content in Zr alloy as reactor structural material to grace, and entering carbon into solid soln. in Zr alloy without forming carbide. CONSTITUTION:As fuel cladding tube or core structural material used in reactor such as boiling water reactor and pressurized water reactor, Zr alloy contg. Zr as main constituent and Fe, Ni, Cr, Sn, Nb, etc., is used. The alloy is superior in mechanical characteristic such as strength and ductility, but corrosion called nodular corrosion is sometimes generated, and mechanical characteristic is decreased. For preventing this, carbon content in the alloy is regulated strictly to <=100ppm, and the alloy is heated to 840-940 deg.C, then cooled rapidly to enter carbon into solid soln., carbide formation with Zr, Fe and others is prevented, thereby nodular corrosion resistance is improved.

Title: Programmable data transfer timing
Inventor: MAIKERU EI GAGURIARUDO
IPC: G06F12/00
Filed: 1989-06-28
Abstract: PURPOSE: To enable various memory devices to operate at different speeds by a single CPU by programming plural clock delays corresponding to the reference clock of a central processing unit, generating plural corresponding delay clock signals, and supplying selected one to a memory source. CONSTITUTION: A memory device 4 does not have its own timing signal and operates in response to a specially phase-controlled timing signal of the CPU 2 instead. Time delays by phase matching among timing signals transmitted to respective selected memory devices 4 are so programmed that the CPU 2 is made to read out data received after the delay of an effective data readout window following a CPU timing cycle. Consequently, adequate selection-readout memory timing can be guaranteed by the programmed phase shift of the CPU 2 as to each selected memory device 4.

Abstract: PURPOSE:To accurately detect an absolute address by controlling adjustably a counter for detecting the number of revolutions of a disk by the number of tracks having stopped or jumped at the time of searching or particular reproducing and regarding a count value as the absolute address at an information detecting point. CONSTITUTION:When a frame No.1 is detected by the information detecting point of a pickup 3 based on a bit of frame number information detected by a frame number detecting circuit 11, the counter (up/down counter) 14 counts up the number of revolutions generated from a revolution detector 13 as one per revolution of the disk 1.

A zero level comparator 16 stops the pickup 3 at the point that the track No.Nb jumped by counting a detecting pulse by a built-in counter is turned into Nb=Na. Nb is added with a count of the counter 14 to be an absolute address.

Title: Solid-state image sensor
Inventor: ISHIKURA HIDENOBU
IPC: H04N5/335
Filed: 1984-08-07
Abstract: PURPOSE:To reduce the generation of a false signal by using a metal silicide electrode for the gate electrode of a MOS transistor adjacent to the region of a photoreceptor, thereby forming a self-aligned light-shielding film. CONSTITUTION:An image sensor has a photoreceptor 1, a vertical signal wire 4, the drain contact 5 of a MOS transistor, and the gate electrode 9 of the MOS transistor having a light shielding property made of metal silicide. The silicide includes, for example, Pt silicide, Mo silicide, with its thickness being 1,000Angstrom  or larger. A signal charge readout type stores an electric signal in the photoreceptor 1, and produces a signal stored by increasing the voltage of the vertical scanning wire externally by the wire 4. Thus, the electrode 9 itself becomes equivalent to have the light shielding film including the self-aligning property by the gate electrode 9 having the light shielding property, thereby enabling to completely shield the light on the gate.

Title: Integrated time measurement method and electrical instrument
Inventor: HASEGAWA NOBUO
IPC: H04N5/44
Filed: 1995-07-03
Abstract: PROBLEM TO BE SOLVED: To reduce the cumulative error of the integrated time. SOLUTION: When a measurement command is turned on, the integrated time data Ts are read out of a nonvolatile memory 4 and preset at a timer counter CNT of a RAM 3 (100). The data Ts are equal to the value that is shown as Ts=(10min.×n+5min.) when (n) is defined to a positive integer. Then the ON time Ton is measured by the counter CNT where the data Ts are preset (101), and it is always checked whether the time Ton is equal to an integer multiple of 10min. (102). The time Ton becomes equal to an integer multiple of 10min. when 5min. elapsed after the measurement command is turned on. Under such conditions, (Ton+5min.) is written in the memory 4 as the data Ts. Thereafter, (Ton+5min.) is defined as the data Ts every time the time Ton is increased by only 10min.

Filed: 1988-07-06
Abstract: PURPOSE:To prevent a car speed from being increased suddenly as an up shift speed change is conducted during an automatic engine brake, by prohibiting other speed changes except for the time of foot brake operation, during a down shift speed change for engine brake. CONSTITUTION:When there occurs the state of operation in which an engine brake is necessary, an automatic engine brake means, in accordance with the signal of an engine brake necessary condition discriminating means inspecting this, exerts an engine brake by conducting a down shift speed change putting an automatic transmission to a low speed step.

Title: Dimmer for illuminating lamp
Inventor: TAKIZAWA TETSUYA
IPC: H05B37/02
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To provide a dimmer for an illuminating lamp capable of reducing power consumption by reducing the luminance of the illuminating lamp. SOLUTION: An AC voltage to be supplied to an illuminating lamp is full wave-rectified, thereby producing a serrate wave which is varied in synchronism with a full-wave rectifying signal. Subsequently, the range of an arbitrary level between minimum and maximum levels of the serrate wave is set. If the level of the serrate wave is within the range, a rectangular wave signal in an 'L' level is generated; in contrast, if it is out of the range, a rectangular wave signal in an 'H' level is generated. Since a MOS-FET is turned on or off in response to the rectangular wave signal, the AC voltage to be supplied to the illuminating lamp has a waveform which is cut in the vicinity of a peak value, thereby reducing the luminance of the illuminating lamp by the cut amount so as to achieve dimming.  The dimming of the illuminating lamp leads to reduction of power consumption, with an attendant advantage of a remarkable effect of power saving. The above-described range of the level can be appropriately changed by a level range adjuster 7, thus arbitrarily changing the dimming amount within a predetermined range.
