Title: Dc motor control circuit
Inventor: MATSUI TAKAHIRO
IPC: H02P7/29
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To smoothly a rotate a motor, by connecting a filter circuit and circulating current diode in series with a DC motor, thereby upgrading the efficiency of power utilization. SOLUTION: A filter circuit is constituted of a capacitor 3 and a choke coil 4. And, a circulating current diode 2 is provided. Then, the filter circuit and a DC motor 12 are connected in series while a switching transistor 1 is turned ON, and a power source voltage is applied between the terminals of the series circuit. At this time, a voltage extremely similar to a direct current is applied to the motor 12 due to the presence of the filter circuit. Meanwhile, energy stored in the coil 4 while the transistor 1 is turned OFF is discharged at the time of ON of the transistor 1. Thus, its power utilization efficiency is improved. And, relatively smoothly averaged voltage is applied to the motor 12 regardless of ON/OFF of the transistor 1, and its rotating operation becomes smooth.

Title: Flaky particle of alkali metal aluminosilicate and its production
Inventor: TAKAGI TOICHI
IPC: C08K3/22
Filed: 1992-07-27
Abstract: PURPOSE:To obtain flaky particles of an alkali metal aluminosilicate by mixing an alkali metal-based flux to an aluminum-containing raw material and a silicon- containing raw material or a raw material containing aluminum and silicon and heat-treating the obtained mixture. CONSTITUTION:The mixing ratio of an aluminum-containing raw material (e.g. aluminum sulfate having particle diameter of <=5mum) to a silicon-containing raw material (e.g. silica glass powder having particle diameter of <=5mum) depends upon the composition of the objective flaky particle, however, the growth of the flaky particle is promoted by increasing the ratio of the silicon component. The amount of the alkali metal-based flux (e.g. potassium sulfate) is 0.1-20 times weight based on the total weight of the aluminum and silicon in terms of oxide. The mixture is mixed by using a ball mill, etc., and heat- treated at 1000-1600 deg.C to obtain the objective flaky particle of an alkali metal aluminosilicate having a (maximum diameter)/thickness ratio of >=3.

Filed: 1987-09-01
Abstract: PURPOSE:To scatteringly produce the identifiers by calling out a means Qk-1 with a memory area Tk-1 serving as a master defined as an argument. CONSTITUTION:In case is impossible to produce an identifier imk with use of the information Wk, a means Qk-1 is called out with a memory Tk-1 serving as a master defined as an argument and the return value of the means Qk-1 is stored in a part IMk-1 of a memory area Tk. Then a means which produces an identifier having the length mk with the information Wk defined as an argument is called out. An identifier imk having the length mk produced by the means Pk is connected with an identifier IMk-1 held in the area Tk for production of an identifier IMk having the length Mk. This identifier IMk is defined as the return value of a means Qk. Thus an identifier IMn can be produced just by calling out a means Qn via either one of memory areas Tn. Then the identifiers can be produced scatteringly since plural areas Tn are available.

Title: Apparatus for sampling dissolved gas in oil
Inventor: SATO MITSUHIRO
IPC: G01N21/35
Filed: 1990-08-21
Abstract: PURPOSE:To stably and continuously detect dissolved gas for a long time by a method wherein a gas chamber side wall comprises a film with a filter for transmitting dissolved gas in oil through formed on an outer peripheral face and light emitting and receiving lenses of an optical fiber are placed in parallel on the chamber. CONSTITUTION:A cap 22 is supported by a device support metal on an oil (insulating oil), and a part of a filter 12 is soaked in oil 7. Infrared rays radiated from a light emitting lens 15a are reflected on reflection mirrors 16a and 16b in this sequence to reach a light receiving lens 15b. At this time dissolved gas 8 in oil which has transmitted through a transmission film ('Teflon(R)' resin) and a filter 12 changes in loss of the light propagating in a gas chamber by selecting wavelength of the infrared rays radiated from the lens 15a to absorp tion wavelength of respective gas. Therefore if dissolved gas 8 in oil in interest has been selected, it is possible to certify existence and concentration of the selected gas 8. In addition, when the gas 8 stays at the time of attaching an apparatus or in the gas chamber, a drain valve 17 is opened to evacuate the gas chamber and exhaust gas.
