Title: Optical device
Inventor: AMAKO ATSUSHI
IPC: H04N9/31
Filed: 1989-02-13
Abstract: PURPOSE:To simplify the constitution of the projection type optical system and to reduce the size thereof by using space modulating elements in a reflection mode by optical reflecting elements and executing optical path sepn. by polarized light separating elements. CONSTITUTION:The optical system is constituted, successively from the side near a light source 101, of a polarizer 102, the polarized light separating element 103, a color separating element 104, the 1st to 3rd space modulating elements 108 to 110, and the 1st to 3rd optical reflecting elements 105 to 107 corresponding thereto. The color light of a lamp 501 is polarized to linearly polarized light by the polarizing plate 102 and is separated to red, green and blue by a dichroic prism 104 at the time of projection. These light rays are modulated by the respectively corresponding space modulating elements 108 to 110 and are then reflected by the optical reflecting elements 105 to 107 so as to be synthesized by the polarized separating element 103. The synthesized light is imaged onto a screen 503 by a projecting lens 502. The constitution is, therefore, simplified and the device is miniaturized.

Title: Bar code reader
Inventor: KOBAYASHI KEIICHI
IPC: G06K7/10
Filed: 1985-02-21
Abstract: PURPOSE:To enable stable interpretation processing of bar code by detecting the reception level of reflected light and in case outside or reception level, regulate the quantity of irradiated light. CONSTITUTION:The light projector 1 irradiates light on the bar code with the initially set quantity of light and the output of the image sensor 3 receiving the reflected light from the irradiated light on the bar code is amplified by the amplifying circuit 4 and converted to continuous signal from dispersed signal by a waveform shaping circuit 5. The scanning part of the converted signal is averaged by the hold circuit 8 and the resulting signal is held. The held signal is converted to digital signal by the reception signal level judgment circuit 9 and input into the microprocessor 10 via the input port 10a. The microprocessor 10 based on the light reception level, commands radiation light quantity to the light quantity regulation circuit 2 from the output port 10c where the light reception signal level judgment circuit 9 output is outside the prescribed range. By this method, waveform shaping and binarizing is carried out at a fixed signal level and are not effected by the printing condition of the bar code.

IPC: H05B41/32
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To miniaturize a device, that is, make it compact by suppressing heat generation in drive as much as possible. SOLUTION: A drive control circuit 6 stops the drive of a DC/DC converter 3, when the voltage Vp of a battery B detected by a voltage detecting circuit 2 is a prescribed threshold V1 or below or exceeds a prescribed threshold V3 (>V1), simultaneously outputs drive control signals FC1 and FC2 consisting of pulse line signals whose phases oppose each other to FETs 31 and 32 respectively to drive the DC/DC converter 2 when the voltage Vp satisfys V1<Vp<=V2 (V2<V3), and alternately outputs the drive control signals FC1 and FC2 to the FETs 31 and 32 respectively to drive the DC/DC converter 3 when the voltage Vp satisfys V2<Vp<=V3. When the battery voltage is high, the FETs are alternately switched to drive one of them, so that a charging current is suppressed and a load caused by the heat generation of the respective FETs 31 and 32 can be reduced.

Title: Magnetizing apparatus
Inventor: SOGABE MASATOYO
IPC: H01F13/00
Filed: 1987-02-18
Abstract: PURPOSE:To prevent breakdown of magnetic plates, by applying a cushioning film around the inner surface of the main body of a magnetizing apparatus. CONSTITUTION:A cushioning film 6 is applied around the entire inner surface of a main body 1 of a magnetizing apparatus. At this time, the cushioning film 6 is openly expanded from the upper and/or lower ends of the main body 1 and extended outward. Thus a guide parts 6' are formed. A rotor 8, in which a shaft 7 is inserted and fixed, is inserted into the cylinder of the main body. At this time, even if the rotor is slightly deviated, the rotor can be suitably centered and slidden in owing to the inclination of the guide parts 6' of the cushioning film. Even if magnets 9 are contacted with the inner surface of the main body 1, breakdown of the magnets 9 can be prevented with the cushioning action of the film.

Title: Position detecting circuit for encoder
Inventor: INOKI AKIHITO
IPC: G01D5/245
Filed: 1990-02-15
Abstract: PURPOSE:To increase the frequency of the detected signal which can be inputted and to improve the processing speed as a whole by providing a second counting means for up-counting or down-counting by every '1' bit in following the counted value of a first counting means. CONSTITUTION:A U/D counter 41 performs counting based on up/down signals A and clock signals B supplied from a counter control circuit 42. Namely, the counter 41 performs the up-countings or the down-countings by every '1' bit following counted values phi of a U/D counter 24 under the control of the counter control circuit 42 all the time. Therefore, the counted values phi are continuously increased or decreased, by, e.g. '1', '2', '3', and '4'..., and data skipping does not occur. As a result, the frequencies of the detected signals sin theta and cos theta of the detected signals which can be inputted become the frequencies obtained by the specified expressions because it is not required to consider the data skipping. Thus, the input of the frequencies three times more than the frequencies in a conventional circuit can be performed.

Abstract: PURPOSE: To prepare pulp having stabilized quality, easily, from nonwoody cellulosic fiber, by treating the fiber with basophilic bacteria capable of producing protopectin-decomposition enzyme having an optimum pH in the lakaline region.  
     CONSTITUTION: Nonwoody cellulosic fibers such as bast of hemp, "mitsumata", "kozo" (raw material of Japanese paper), etc. or leaf cellulose of Manila hemp, New Zealand hemp, etc. are reduced to pulp by fermentation scouring using basophilic bacteria capable of producing protopectin-decomposition enzyme having an optimum pH in the alkaline range.
