Title: Silver halide color photosensitive material for photographing
Inventor: KASHIWAMURA SHINSAKU
IPC: G03C1/035
Filed: 1999-08-23
Abstract: PROBLEM TO BE SOLVED: To restrain the increase of fogging with time by a small amount of radiation in the environment without accompanying any deterioration of properties such as sensitivity and granularity by providing a photosensitive layer in which the reciprocity law characteristics being the difference of logarithmic values of exposures necessary for giving minimum densities at two different exposing times is made to have a specified range. SOLUTION: This photosensitive material has such a photosensitive layer that the reciprocity law characteristics ΔlogH=Ss-Sh is made into 0.4-1.0 (wherein Ss is the logarithmic value of the exposure necessary for giving +0.1 minimum density when the exposure time is one millionth of a second; Sh is that necessary for +0.1 minimum density when the exposure time is one ten-thousandth of second; ΔlogH is the reciprocity law characteristics). This photosensitive layer contains such a silver halide emulsion that the silver halide particles which have 1-1.5 average number of development beginning points per one particle when unexposed silver halide particles are exposed with natural radiation account for 50% or more of the whole projection area.  Planar silver halide particles containing 1×10-9-1×10-12 mol of a multivalent metal compound per one mode of silver halide are arranged in the outer peripheral region.

Filed: 1986-10-03
Abstract: PURPOSE:To enable the confirmation of penetration without any visual check and prevent the excessive or insufficient feed of a drill in boring process with the relative advance of a workpiece and the drill by generating a fluid pressure difference between a drilling side and a through side, and detecting a pressure change upon completion of drilling. CONSTITUTION:The rear end of a workpiece 1 as a through side 7 is fixed to a chuck 9 and an O-ring 12 is fitted between a chamber 11 and a pre- machined hole 6, thereby keeping continuity from the hole 6 to the through side 7 under airtightness. From a supply source connected to the end 10b of a pipe 10, gas of constant pressure higher than atmospheric pressure at an initial machining side 5 is fed under pressure with a valve 15 kept open, thereby generating a pressure difference between the initial machining side 5 and the through side 7. And while the readings of a pressure gauge 13 or a flow meter 14 are being detected, a drill 13 is fed to start cutting the initial machining side 5. When the readings of the pressure gauge 13 have dropped or the flow meter 14 has indicated a value of penetration as preliminarily measured, the feeding of the drill 13 is stopped and a drilling process is completed.

IPC: G02B6/12
Filed: 1984-11-10
Abstract: PURPOSE:To simplify the peripheral circuits and to reduce the cost, by inputting the output from the optical switching elements of both group into the different optical wavelength demultiplexer, and connecting each half of the output of the optical wavelength demultiplexer to two optical wave multiplexers, and repeating it until the output becomes '1'. CONSTITUTION:Optical switching elements compose one pair by two pieces, and three step structure is employed. The optical switching elements 110, 111 of the first step relate to the selection to select either group of 0-3 of 4-7 as its output. The optical switching elements 112, 113 of the second step relate to the selection to select either group of wave length lambda1, lambda2 or lambda3, lambda4 as its output. The optical switching elements 114, 115 of the third step select the final and single wave length to be outputted. For example, when the optical switching elements 110, 112, 114 are closed, the signal inputted from the input terminal (0) is outputted from the output terminal 8. In this way, low cost and stable optical space division switch is obtained with being composed of smaller number of the optical switching elements, simplifying the peripheral circuit.

Title: Battery-charging apparatus
Inventor: TSUZUKI HANZO
IPC: H02J7/04
Filed: 1988-09-22
Abstract: PURPOSE:To avoid lowering of discharge characteristics due to memory effects as much as possible by starting the quick discharge (heavy load discharge) of a secondary battery, when an end voltage is detected, and by stopping said quick discharge battery, when an overdischarge voltage is detected. CONSTITUTION:When an end voltage sensing circuit 2 detects the end voltage of a secondary battery 1 at the time of an ordinary discharge of said battery, a forced discharge control circuit 4 quickly discharges said secondary battery 1 by connection of a quick discharge resistor, etc., with the secondary battery 1. When the secondary battery 1 reaches a predetermined overdischarge voltage by said quick discharge, said forced discharge control circuit 4 stops the quick discharge in response to the detection of an overdischarge voltage sensing circuit 3. In this manner, when the secondary battery 1 is quickly discharged to said overdischarge voltage and charged thereafter, said secondary battery 1 regains its innate initial discharge characteristics. Therefore, even if the charge and discharge of the secondary battery having memory effects is conducted frequently, lowering of discharge characteristics due to said memory effects can be prevented effectively.

Filed: 1993-09-22
Abstract: PURPOSE:To obtain an information recording medium where the repeating time of recording, updating and erasing is not restricted without the easy alternation and dissaperance of data by means of magnetism from an outside by heating a recording part, permitting the phase state to change and recording visible information. CONSTITUTION:When visible information is recorded in the display part of an IC card surface, irradiation is executed with a laser light beam 25 from a laser oscillator. The laser light beam reaches to a phase change layer 14 through a protective layer 16 and a dielectric layer 15 and executes heating. When the heated part of the phase change layer 14 is rapidly cooled, only the part becomes a non-crystal state 26, the transmissivity of light is reduced, reflection light quantity from a reflection film 12 is reduced to be smaller than the reflection light quantity of the crystal state part and the part looks dark. Therefore, irradiation is executed at plural places of the phase change layer 14 with the laser light beam from the laser oscillator so that not only a character but also a picture, a pattern, etc., can be recorded. When required heat is added by the laser light beam, etc., for changing the recording film 14 into the crystal state, visible information is erased.
