Title: Optical card
IPC: G11B7/24094
Filed: 1992-03-13
Abstract: PURPOSE:To facilitate the identification of two regions by providing a visually observable transparent layer on an optically recordable recording layer and a recording layer for merely guiding a light beam. CONSTITUTION:The recording layer 2 is laminated on a substrate layer 22. The transparent layer 21 is laminated to protect the recording layer 2 over the entire part of the optical card 1. The transparent layer 21 is constituted to vary the transmittance of light in the recordable region 13 of the recording layer 2 and in the region 12 for merely guiding the light beam. Namely, the transparent layer is so formed that the transmittance of the region 13 is higher than the transmittance of the region 12. As a result, the identification of the two regions is enabled and there is no need for a user to use more than necessary nerves.

IPC: G05D16/00
Filed: 1980-07-03
Abstract: PURPOSE:To give an optimum change to the control parameter of a control meter according to the process gain and to maintain the optimum control, by calculating the process gain of the system to be controlled from the flow rate that flows through a fluid pipeline and the differential voltage of a means to control the flow rate. CONSTITUTION:The different types of fluids are supplied to the mixing place C from suppliers A and B and transferred to the demander D via a control valve 3 after mixed at the place C and with the pressure PO of a pressure transmitter 4 at the output side of the valve 3 set as a target. Pressure transmitters 5 and 6 are provided before and after a damper 2 that controls the flow rate of the above- mentioned fluid pipeline to obtain the differential voltage before and after the damper 2. This differential pressure is supplied to an arithmetic device 7. At the same time, a flowmeter 1 is provided to the fluid pipeline to measure the flow rate of the pipeline and then apply the result of measurement to the device 7. Thus the device 7 calculates the process gain to be applied to a control meter 8 which controls a damper operating machine 9 based on the differential pressure before and after the damper 2 plus the flow rate of the fluid pipeline. In such way, an optimum control parameter is obtained for the meter 8.

Title: Attracting method of paper
Inventor: NISHIMURA KUNITOSHI
IPC: B65H7/02
Filed: 1981-06-13
Abstract: PURPOSE:To automatically operate handling work of paper, in a paper handling device for performing page turning over operation or the like in a book, by constituting the device in such a manner that an attractor is separately located in a prescribed distance from a surface of paper, and is adjusted attractive force and the distance from the surface of paper. CONSTITUTION:An attractor 2 is set to a position X from a surface of paper 1  by a position detector 7, and made to approach to the surface of the paper 1  while performing attraction of the attractor 2 by a controller, not shown in the  drawing. When the attractor 2 approaches a certain distance to the surface of  the paper 1, a sheet of the uppermost paper can be attracted. In this way, a  change of pressure in a hollow body 3 is casued, detected by a pressure detector 6 and input to the controller, not shown in the drawing. Thus the attractor  2 is released from further descending and shifted to remove the paper 1. In this  constitution, the attractor 2 always performs attraction at a distance apart from  the surface of the paper 1, and attraction of plural sheets can be prevented and automation of handling work has thus become possible.

Title: Environment controller for hifix section of ic handler
Inventor: TSUDA AKIYOSHI
IPC: H01L21/02
Filed: 1995-03-23
Abstract: PURPOSE: To safely control the environment, such as the temperature, etc., in the HIFIX section of an IC handier at a low cost by connecting a plurality of one-way check valves to the piping of the HIFIX section. CONSTITUTION: One-way check valves 15 and 16 are provided on the upstream side of the conventional gas introducing pipe 13. The valve 15 is provided for introducing a gas through the conventional drier 11 and used at the time of low-temperature tests as in the past. Since the valve 16 can introduce a large quantity of gas supplied to the valve 16 through an oil mist separator 8 and filter 8 to the HIFIX section of an IC handler through the pipe 13, high- temperature tests can be performed within a safe temperature range so that the temperature in the HIFIX section cannot exceed a limit value. Thus the environment in the HIFIX section can be controlled at a low cost by only adding a gas pipeline to the conventional gas introducing pipe 13.

Title: Transmission device for working vehicle
Inventor: OKUDA SHIRO
IPC: B60K20/02
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To suppress degradation in the efficiency attributable to sub transmission while the sub transmission is smoothly performed with small shock by regulating the transmission of a sub transmission device only in a condition where a main transmission device is in the high-speed range. SOLUTION: A main transmission lever 31M is also used as a sub transmission lever 31S. A sub transmission guide groove SS in a transmission guide G provided on an operation panel regulates the sub transmission of the main transmission lever 31M, i.e., the operation between a high transmission guide groove HS and a low transmission guide groove LH only when the main transmission lever 31M is in the forward high-speed range FH and a rearward high- speed range RH. Thus, the main transmission lever 31M enables the sub transmission only when it is at other positions including the neutral position N. Because the main transmission device 31M allows the transmission of the sub transmission device 31S in a condition where the difference in the traveling speed is not so large before and after the sub transmission, the traveling speed is not dropped so much while performing the sub transmission with small shock.

Abstract: PURPOSE:To perform detection of radon at high sensitivity and high reliability by collecting radioactive decayed materials of radon on a filter, and storing the energy of radiation in a stimulated phosphor, and measuring the amount of radiation energy stored in the stimulated phosphor. CONSTITUTION:Radioactive decayed materials are collected in a filter 13 and the filter 13 and a stimulated phosphor sheet 21 comprising layers of stimulated phosphor formed into a sheet are disposed in proximity to each other inside a black box 20 and the energy of radiation emitted from the radioactive decayed materials collected in the filter 13 is stored in the sheet 21.

Abstract: PURPOSE:To simplify the constitution of an automatic two step type variable speed gear by providing a one-way clutch between a rotary object and another rotary object. CONSTITUTION:A one-way clutch 26 is provided between a first sun wheel 16 and a second carrier 24. This puts the torque generated in the one-way clutch 26 during high speed rotation into power circulation between the first sun wheel 16 and the second carrier 24 with the result that the torque is not transmitted to the case for supporting the first sun wheel 16 and the second carrier 24; consequently, the reinforcement of the case becomes unnecessary and the constitution of the automatic two step type variable speed gear is simplified.

Filed: 1983-05-25
Abstract: PURPOSE:To obtain a phase plate which has relaxed work precision and maintains the functions even to divergent luminous flux by pasting two phase plates which have the same specific angle between plate surface normals and optical axes on specific condition. CONSTITUTION:Work is so performed that the plate surface normals of lambda/8 plates 4 and 5 having the same dimensions are at the angle beta to their optical axes 6 and 7, and those plates are set while their orientation flats 8 for optical axis display are symmetrical about pasted surfaces and adhered together in such a way that adhered surfaces of the lambda/8 plates 4 and 5 form a wedge with an angle delta with an interposed isotropic adhesive layer 9 which has the same refractive index with the lambda/8 plates 4 and 4, thus obtaining lambda/4. When this lambda/4 plate is applied to an ellipsometer, neither high-precision work nor assembly is required specially and a uniform quenching ratio is obtained even if a beam having a very large angle of divergency from a semiconductor laser, etc., is used without being collimated.
