Title: Volume modulation type light-controlling material, volume modulation type light-controlling composition, and optical device
Inventor: UEMATSU TAKASHI
IPC: G09F9/00
Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To provide a light-controlling material with which high contrast for controlling of light can be obtd., a light-controlling compsn. using the light- controlling material, and an optical device using the light-controlling compsn. SOLUTION: This light-controlling material contains a light-scattering member 14 in a polymer gel 12 which reversibly swells and shrinks by absorption and release of a liquid according to external stimulation. In this material, when the polymer gel 12 shrinks (b), the concn. of the light-scattering member 14 in at least a part of the polymer gel exceeds the saturation scattering concn., which decreases the scattering efficiency of light 16. When the polymer gel 12 swells (a), the scattering efficiency of light 16 increases.

Title: Method for measuring dielectric loss of cable
Inventor: IGA ATSUSHI
IPC: G01R27/26
Filed: 1989-02-09
Abstract: PURPOSE:To make it possible to perform safe measuring work in a short time by measuring an AC voltage which is applied on a cable conductor and a charging current for the cable from the outputs of an instrument transformer and a current transformer which are attached to a cable line. CONSTITUTION:An AC voltage which is applied on a conductor 2 of a cable 1 is obtained from an instrument transformer 20. A charging current for a cable 1 is obtained from a current transformer 9 which is connected to a sheath 7 of the cable 1. A constant phase angle is present between the primary and secondary windings of the transformer 20. The phase angle is linearly proportional to a burden with a meter 30 which is connected to the primary side of the transformer 20. Therefore, the phase angle is obtained from the burden, and the phase of the transformer 20 is corrected. In this way, the phase angles of the AC voltage and the charging current can be measured accurately, and a dielectric loss can be measured. In this method, high voltage work at a high place can be avoided, and the safe, quick measuring work can be performed.

Title: Balance chuck
Inventor: KOBAYASHI TATEO
IPC: B23B31/14
Filed: 1984-02-20
Abstract: PURPOSE:To remarkably improve rigidity of a chuck body for precise heavy cutting by compensating centrifugal force applied to a pawl for gripping a work with a balance weight. CONSTITUTION:When a chuck body 1 is rotated, moment of rotation in the clockwise direction around the center of a connecting portion 14 acts on a balance weight 11. This causes radially outward resilent deformation of the weight 11 around the connecting portion 14, and an engaging portion 11a pushes forward the rear surface 3e of a master jaw 3. This prevents lifting phenomenon of a pawl 5, and therewith reduction of gripping force caused by rotation of the chuck can be compensated and initial gripping force is maintained even at high speed rotation to allow heavy cutting.

IPC: G11C29/00
Filed: 1989-02-10
Abstract: PURPOSE:To surely invert the output signal based on disconnection of a fuse and to reduce the power consumption by providing a control signal generating circuit which generates a specific control signal based on disconnection or non-disconnection of the fuse. CONSTITUTION:The control signal generating circuit is provided to generate the control signal based on disconnection or non-disconnection of the fuse. When the fuse 1 is not disconnected, the potential of the other end of the fuse 1 is held in the high level by the action of a resistance R1 though a chip select signal is outputted to operate a first transistor(TR) Tr5. After the fuse 1 is disconnected, the potential of the other end of the fuse 1 goes to the low level based on the operation of the first TR Tr5; and when a second TR Tr6 is turned on in this state, the other end of the fuse 1 is stably held in the low level. Thus, the output signal is surely inverted based on disconnection of the fuse and the power consumption is reduced.

Title: Pll circuit
Inventor: YAMAGISHI AKIHIRO
IPC: H03L7/187
Filed: 1990-02-13
Abstract: PURPOSE:To simplify this circuit by applying the initial setting of an output frequency for plural number of times separately at the switching of frequency. CONSTITUTION:A loop switch 5 is opened so as not to give the influence of an output of a phase comparator 1 onto a control voltage of a VCO 3 to switch the frequency division ratio of a variable frequency divider 4 from N1 to N2 and a control voltage Vc1 generating a frequency close to f02 by the VCO 3 is generated by a 1st D/A converter 6. Since a 1st D/A converter 6 and the VCO 3 have an error, the output frequency of the VCO 3 is not f02 and the output frequency of the VCO 3 has a frequency error fe. On the other hand, a frequency comparator 9 compares the frequency of a comparison signal fv with the frequency of a reference signal fr to detect the frequency error fe and the difference of the control voltage of the VCO 3 equivalent to the frequency error fe detected by a frequency comparator 9 is outputted from a 2nd D/A converter 61. The difference of the control voltage is fed to the control voltage of the VCO 3 via a 2nd adder 71. Thus, the circuit is simplified.

Title: Over-discharge preventing device for secondary battery
Inventor: MIYATA SHOICHIRO
IPC: H02J7/00
Filed: 1995-02-21
Abstract: PURPOSE: To prevent the over-discharge of a battery in a bicycle with auxiliary power. CONSTITUTION: In an over-discharge preventing device for battery in which a discharge is performed in the on-vehicle state, a CPU 31 stores discharge stop information in a nonvolatile memory 6 when a forced discharge stop is detected. When a power source switch 7 is then operated from on state to off state, and further returned to on state, the operation of the CPU 31 is started to read the information stored in the nonvolatile memory 6. When the read information is the discharge stop information, a battery terminal voltage VB is compared with a standard voltage. When the former exceeds the latter, the discharge stop information written in the nonvolatile memory 6 is reset to lay a battery 22 in the dischargeable state. On the other hand, when the former never exceed the latter, the discharge stop state is kept to prevent the over discharge.
