Title: Coil control circuit for electromagnetic clutch, brake and the like
Inventor: MURAKAMI YOSHISUKE
IPC: B60W10/18
Filed: 1985-06-05
Abstract: PURPOSE:To make a coil control circuit compact and reduce costs, by connecting a coil at an intermediate position between bridge-connected transistors, and supplying a PWM (pulse width modulated) pulse to a base of the transistor on one side and an on-off control current to a base of the transistor on the other side. CONSTITUTION:In bridge-connected transistors 22, 24 26 and 28, a PWM pulse is supplied to bases of the two transistors 22 and 24 connected with a power line 30a, and an on-off control current is supplied to bases of the two transistors 26 and 28 connected with another power line 30b. A coil 32 is connected at an intermediate position between the transistors 22 and 24 and the transistors 26 and 28. The circuit enables a direction of current flowing through the coil 32 to be changed, thereby preventing generation of a residual magnetism. Further, overexcitation of the coil 32 may be effected by PWM control with use of a rate power source only.

Title: Conductive roller
Inventor: ISHIKAWA KAZUHISA
IPC: G03G15/08
Filed: 1992-05-14
Abstract: PURPOSE:To provide a roller having wholly uniform conductivity without being affected by an outside. CONSTITUTION:A conductive elastic body layer 13 is formed on a core bar 12 and a resistance adjusting layer 14 is provided on the layer 13. The resistance adjusting layer 14 only incorporates epichlorohydrin rubber as a rubber material. Ethyl acetate is used as a solvent for epichlorohydrin rubbers.

Title: Method for measuring average valency of copper in copper compound
Inventor: KUBOTA MARI
IPC: G01N31/00
Filed: 1988-05-19
Abstract: PURPOSE:To accurately measure the average valency of copper in a copper compound, by using an acid generating no free iodine alone in the coexistence of an iodine ion to dissolve the copper compound and subsequently quantifying the generated amount of iodine and the amount of copper. CONSTITUTION:A very small amount (about 2mg) of a powder sample of YBa2 Cu3O7-x is taken to be put in a beaker covered with light blocking paper and about 5ml of 50% acetic acid containing 1% of potassium iodide is added to said sample. Since the superconductor is dissolved after about 20min, the resulting solution is diluted with about 60ml of distilled water. This solution is titrated with an N/100 or N/500 sodium thiosulfate solution to determine the amount of iodine. Potassium iodide/g is added to the titrated solution to dissolve copper iodide completely and copper is subsequently analyzed by ICP photometric analysis to determine the amount of copper. The average valency of copper is calculated from the ratio of the amount (mol unit) of copper and the amount (mol unit) of iodine.

Title: Fully optical optical nonlinear type element
Inventor: TOKUDA YASUKI
IPC: G02F1/35
Filed: 1991-04-24
Abstract: PURPOSE:To obtain the element with which the characteristic for switching output light intensity is obtd. purely by light by adopting the constitution having the characteristic that the intensity of the output light is steeply changed with the intensity or wavelength of input light by a change in the internal electric field of a quantum well layer by photoexciting carriers. CONSTITUTION:The quantum well 3 consisting of the periodic laminated structure held by two clad layers 2, 4 is formed on an (n) type substrate 5. The exciting carriers are generated by absorption in the quantum well 3 when the input light is made incident on this element. The exciting carriers act to negate the built-in electric field by a p-n junction when the numbers of the electrons and holes which are the exciting carriers are both designated as (n). The energy band structure in the quantum well region inclines less steep with an increase in the (n). The wavelength of the optical transition is shortened by a Stark effect and, therefore, the response relation of the (n) and the absorption coefft. is obtd. if the input wavelength is selected.
