Title: Coating liquid coating device for sheet electrode
Inventor: TAKAYAMA HAJIME
IPC: H01M4/26
Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To form a coating of a continuously approximately uniform coating of an electrode mix on a sheet shape electrode supporting base material in the case that viscosity of a coating liquid is comparatively low by detecting a use quantity of the coating liquid in a coating liquid containing hopper by means of a float type float, replenishing the coating liquid according to the use quantity of the coating liquid, and keeping a pressure of a slit part to control a thickness of the coating liquid to be approximately constant. SOLUTION: A sheet shape electrode base material 2 is traveled closely touching the periphery of a rotating coating back up roller 3 to adhere a coating liquid 9 on the electrode base material 2. When the coating liquid 9 in a coating liquid containing hopper 4 is consumed to lower its surface, a float type float 10 moves down, and a float position measuring mean 11 measures the lowered distance. If the lowered distance is more than a preset threshold value a computing section 13 operates a supply pump 15 through an instruction mechanism 14 to replenish the coating liquid 9. Thereby, a pressure of the coating liquid 9 against the sheet shape electrode base material 2 is approximately constant to provide a film of an electrode mix with a desirable and even thickness.

Title: Measurement for film thickness
Inventor: YAMADA SETSU
IPC: G01B15/02
Filed: 1984-12-03
Abstract: PURPOSE:To enable measuring of the film thickness sequentially even when the film to be measured is non-transparent, by burying a radioactive substance into a substrate to measure the intensity of radiation from the radioactive substance after the formation of the film being measured. CONSTITUTION:A radioactive substance 2 is introduced into a substrate 1 intended to form a film 3 to be measured. Then, the film 3 being measured is formed on the substrate 1. Thereafter, a radiation detector 4 is set above the film 3 being measured as opposed thereto to measure the intensity of radiation from the radioactive substance 2 through the film 3 being measured thereby calculating the thickness of the film 3 being measured. Thus, the thickness of non-transparent film such as aluminum film can be measured as well.

IPC: G03G15/04
Filed: 1990-09-26
Abstract: PURPOSE:To increase the recording speed and reduce limitations of the recording time of unit areas by providing plural numbers of means which emit laser light. CONSTITUTION:Laser light beams emitted by two laser diodes 1 and 1a pass through collimator lens 2 and 2a which are prepared to reach a rotating polygon mirror 3, where the light beams are reflected to scan an image carrier 5 along scanning lines 6 and 6a through an f-theta lens group 4. The laser diodes 1 and 1a are so installed that scanning expected lines 8 and 9 are one pitch away from each other on the image carrier 5. Consequently, the angle between a virtual scanning return line and the scanning expected lines is larger than a conventional example, a larger area can be scanned at the same frequency of scanning, and the limitation of the recording time of the unit areas are reduced.

Title: Amplifying circuit
Inventor: UMEZAWA ATSUSHI
IPC: H03F3/34
Filed: 1989-10-03
Abstract: PURPOSE:To prevent a DC offset voltage from occurring between input and out terminals by supplying the output current of a voltage/current converter to the input electrode of a fourth transistor in a current mirror circuit. CONSTITUTION:The input voltage Vin of the input terminal 4 is also applied to the base of the first transistor Q1 of a differential amplifier 1, and the collector currents of the first transistor Q2 and a second transistor Q go to currents 2/1I2 of the current 2I2 of a constant current source 2 with a feedback circuit 6. And a current I3 that flows out from a point P to an output terminal 7 side goes to (I1-I2), and the output voltage Vo of the output terminal 7 goes to I3.Ro=Vin. At such a case, since the operating currents 12 of the first and second transistors Q1 and Q2 of the differential amplifier 1 are equal with each other, no DC offset voltage due to the fluctuation of the voltage between the base and the emitter of the transistor occurs between the input and output terminals.
