Title: Data storing method for microcomputer type controller
Inventor: TOUYA KENJI
IPC: A47J27/00
Filed: 1995-04-04
Abstract: PURPOSE: To use an E<2> PROM for a long period by storing data to be written in the E<2> PROM in a RAM in advance and writing the data in the RAM in the E<2> PROM only when a power failure detecting means generates a power failure detection signal. CONSTITUTION: Each data to be written in the E<2> PROM 12 is generated, the data is written in the RAM 13. When a power failure occurs and the power failure detecting means 31 outputs the power failure detection signal, the data to be written in the E<2> PROM is moved from the RAM 13 to the E<2> PROM 12. Only when a power failure occurs, writing operation to the E<2> PROM 12 is performed, so the frequency of data writing to the E<2> PROM 12 becomes less than that of a conventional method which writes the data to be written in the E<2> PROM 12 each time the data to be written is generated. Consequently, the inconvenience that the E<2> PROM 12 deteriorates in performance in an early stage can be reduced, so the E<2> PROM 12 can be used for a long period.

Title: Birefringence measuring device
Inventor: SAKAI KIYOKAZU
IPC: G01N21/23
Filed: 1992-02-29
Abstract: PURPOSE:To reduce burden on a measuring person, and measure retardation accurately by judging automatically that a ratio of the maximum to the minimum of the transmitted light intensity is equal to or smaller than a prescribed value when a sample is measured independently, and measuring it again by superposing sheets, whose retardation is already known, upon each other. CONSTITUTION:A 1/4 wavelength plate F14 is retreated from above the axis A of a device, and a sample S is set in the device, and a measurement operation is started. While rotating a polarizer and an analyzer, a data processing control device 10 measures the transmitted light with every one degree of an angle, and stores it in a memory. Next, the maximum value and the minimum value of the transmitted light intensity is searched from this data, and when (cosdelta) obtained from the ratio by using a specific formula is smaller than a prescribed value, an operation is finished, and when it is larger than the prescribed value, the optical axial direction of the sample is searched, and the direction of the 1/4 wavelength plate is adjusted to it, and the measurement is repeated from the start. (pi/2) is subtracted from (delta) obtained therby, and this is determined as retardation of the sample. Since the 1/4 wavelength plate is inserted/measured automatically, the retardation can be measured easily/accurately.

Title: Operating device
Inventor: ITO YOSHIYUKI
IPC: H02N2/00
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To minimize the switching frequency of exciting current by making the extendable speed of an extendable means into electric signals whose waveforms are different from each other on extension side and contraction side with one of the first and second fixing means excited and the other non- excited when the extendable means moves in one direction. SOLUTION: Exciting current is supplied to a fixing device 18, for example, so that the magnetic attracting surfaces 22 of the fixing devices 18, 20 may be attracted to a movement reference part constituted of magnetic material, and the saw tooth waveform voltage which goes up rapidly and goes down gradually is applied to an expandable device 16 repetitively with the exciting current not supplied to the fixing device 20. As a result, the fixing device 18 displaces gradually to the fixing device 20 side in a nonexciting condition and in the opposite direction. The fixing device 20 reciprocates to the fixing device 18 by the expandable action of the expandable means 16 and displaces by a distance corresponding to the displacement amount of the fixing device 18.  It is thus possible to minimize switching frequency of exciting current and eliminate need for synchronizing the switching of exciting current with the supply of an electric signal to the expandable means.
