Title: Detector for original size
Inventor: YAMAMOTO HARUO
IPC: G03B27/62
Filed: 1985-03-29
Abstract: PURPOSE:To detect the size of an original by forming an optical transmission path on the reverse surface of an original pressure plate so that one end faces contact glass and the other end part faces a photodetecting element directly or indirectly, and setting its direction in parallel to the optical path of irradiation light from a light source for original exposure. CONSTITUTION:The light source 21 moves forth and back once in the lighting state and the other end part of an optical fiber 51 faces the photodetecting element 53, so the light from the light source 21 does not reach the optical fiber 51 where the original D is present. When the light transmissivity of the original D is high, only light which is attenuated greatly reaches the optical fiber 51 and the light reaches the optical fiber 51 nearly without loss where the original D is not present to irradiate the photodetecting element through the optical fiber 51. For the purpose, the photodetecting element 53 which outputs a detection signal corresponding to the light which is not attenuated is known to decide which fixed forms size the original size corresponds to.

Abstract: PURPOSE:To smoothly operate a synchronizing device by providing a pressure control means which control working pressure of a variable pressure type actuator as to make it high at the initial time of synchronization and make it low at the latter time. CONSTITUTION:When a controller 140 outputs a pulse signal to one of sole-noid change-over valves 113-116 so as to newly supply oil pressure in relating one of oil chambers 73, 74, 77 and 78, the controller computes relative revolution numbers of a synchronizing part and a syncrohnized part of a synchronizing device related to said selected solenoid change-over valve on the bases of a revolution number and a car speed which are detected by a revolution number sensor 144 and a car speed sensor 142, respectively. At the initial synchronizing time where the relative revolution number is great, the controller outputs a pulse signal of relatively low duty ratio and increases the duty ratio with decrease of relative revolution number. After a completion of the synchronizing operation, the controller generates a pulse signal of a duty ratio at which a maximum oil pressure may be produced.

Title: Ion exchange unit
Inventor: HORIUCHI KOUICHI
IPC: C02F1/42
Filed: 1979-05-29
Abstract: PURPOSE: To remove ions only from suspension liquid supplied to a reaction container and a mesh container by a method wherein a stirrer agitating ion exchange resin particles is provided in the mesh container rotating in the reaction vessel.  
     CONSTITUTION: Suspension liquid 8 is supplied 6 to a reaction vessel 5 and is charged into a rotating mesh container 10, allowing the liquid to contact with ion exchange resin particles 9 in the container 10 so that efficient deionization is performed. Because the resin particles 9 in the container 10 are forcedly agitated by a stirrer blade 12, frequent contact between the resin 9 and suspended material in the liquid 8 occurs, which accelerates the speed of deionization. As with the rotation of the container 10, resin particles 9 are stirred continuously and as a result, the resin particles 9 are prevented from being contaminated by the component of the suspension in the liquid 8 which has entered the container 10 from the reaction vessel 5.

Title: Control structure for continuously variable transmission type working vehicle
Inventor: KAMIYAMA HIDEKI
IPC: B60W10/10
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To prevent a practical vehicle speed from getting different from a supposed speed by controlling an output shaft by a shift position correcting means, when an error is generated between a set shift output rotation speed and a detecting shift output rotation speed in setting the advancement. SOLUTION: A movable swash plate of a hydraulic pump moves to a set position by a lever operation of a continuously variable transmission 3 and the lever set position is detected by a lever angle sensor S3. When a set value is set in a rotation speed setting device 23 in response to the detected value and the setting of the advancing area of the movable swash plate position is confirmed, a controller C reads the set value by the set device 23 based on the detected value. It confirms that it is within a work rating rotation speed or less and reads the value detected by a rotation speed sensor S2.  An error allowable quantity is calculated based on the rotation speed set value, and when the rotation speed detection value is higher than the upper limit value of the error allowable range of the rotation speed set value, the movable swash plate is moved to the low speed side by a swash plate control motor 8 so as to reduce the vehicle speed. The vehicle speed is increased in the reversed case. The practical vehicle speed is thus matched to the supposed shift position rightly.

Title: Orientation-controlled organic thin film and film making method
Inventor: KUNITAKE MASASHI
IPC: C08J5/18
Filed: 1995-03-02
Abstract: PURPOSE: To obtain a highly orientation-controlled aromatic compound thin film which is suitable for a liquid crystal thin film, a photoelectric transducer, a nonlinear optical element, etc. CONSTITUTION: An organic thin film is prepared by a process in which halogenide ion or halogen is adsorbed on a metallic substrate, and then an aromatic compound is adsorbed on the metallic substrate. It is preferable that the halogenide ion or the halogen is adsorbed on the metallic substrate before the metallic substrate being immersed in the solvent of an unsaturated aromatic compound. In this way, the halogenide ion or the halogen adsorbed on the metallic substrate reduces the adsorption force between the aromatic compound and the metal surface, promotes the self-organization of the aromatic compound, and improves the orientation of the organic thin film prepared.

Filed: 1983-04-19
Abstract: PURPOSE:To detect the true position of a welded part and thereby to improve the accuracy of measurement, by receiving infrared rays radiated from a ragion in the vicinity of the welded part, and by detecting therefrom the position on the surface of said part at which the temperature of the surface is maximum. CONSTITUTION:Infrared-ray signals radiated from a welded part 3 and inputted to an infared-ray detector 10 are transmitted to a gate scanner 113 through an analog multiscanner 111 and an analog AMP circuit group 112. From the gate scanner 113 the data of N1... are taken out according to instructions of a timing circuit 116, and are compared with preceding data, i.e. the values of a MAX register 117 in a comparator circuit 116. When the input data are larger than the data in the MAX register 117, the values of the input data are put in the MAX register 117 and simultaneously a count signal is delivered to a gate 115. When the content of the MAX register 117 is smaller than the input, the gate 115 is closed so as not to send a signal to a counter 118. Consequently, the position of a peak signal is held in the counter 118.

Title: Optical digital storage
Inventor: TAKEMORI TAMIKI
IPC: H03K3/42
Filed: 1993-03-26
Abstract: PURPOSE:To provide an optical digital storage having a simple constitution and easy for cascade connection. CONSTITUTION:When an input clock signal is changed from (0) to (1), the input signal of an (1) side input terminal, that is, an input data signal value immediately before the change of the input clock signal to (1) is selected for the output of an optical selector 111. Since the value is inputted to the optical selection terminal of the optical selector 112, the output of the optical selector 111 is held to the value, and the value of an output optical signal is held to the value, too. When the input clock signal is changed to (0) again, the output optical signal with the same logical value as the input data signal is obtained. Further, the oscillation in a feedback loop is evaded since proper signal delay and the integration on a signal waveform are accompanied with the operation of the optical selector.
