Title: Positioning controller for servo motor
Inventor: MATSUMOTO TETSUYA
IPC: G05D3/12
Filed: 1987-08-17
Abstract: PURPOSE:To reduce the operating time and labor with a positioning controller for servo motor by using a position fixing device which fixes a control subject, a memory and a process monitor device so that the subsequent operations can be omitted by a single original point resetting operation carried out when a positioning controller is used for the first time. CONSTITUTION:When a control action stop (power supply cut-off) command is given to a positioning controller 3, a process monitor device 6 controls a position fixing device 4, a memory 5 and the controller 3. Then the device 4 fixes a control subject at a position set at that time point and at the same time this fixed position is stored in the memory 5. Then the fixture of the control subject is released when a control action is started and the controller 3 reads out the stored position of the control subject to start the initial position control. Thus the correspondence is maintained between the actual position of the control subject and the control position of the controller even the control action is over. Then the control action can be restarted in a state set when the preceding control action is over in case the controller 3 is started. As a result, just a single original point resetting operation is required when the controller 3 is used for the first time. Thus the operating time and labor can be reduced.

Title: Hydraulic control method and apparatus for belt type continuously variable transmission
Inventor: ITOU HIROSHI
IPC: F16H61/02
Filed: 1983-10-28
Abstract: PURPOSE:To improve speed change responsibility by continuously changing the feed quantity of operation oil and the discharge quantity of the operation oil to the first hydraulic cylinder for changing the effective diameter of a variable pulley. CONSTITUTION:A target rotation speed of an engine for driving an input shaft is determined depending upon the required load amount of the engine from a previously found relationship, and the actual rotation speed of the engine is detected to calculate a deviation between the target rotation speed and the actual rotation speed of the engine. On the other hand, a shift valve device is periodically operated repeatedly between two conditions, and the respective time rates in two conditions of the shift valve device are changed according to the degree of deviation. Thus, the quantity of operation oil fed to the first hydraulic cylinder for changing the effective diameter of a variable pulley or the quantity of operation oil from the first hydraulic cylinder can be changed continuously to properly improve the speed change responsibility.

Title: Ink jet head
Inventor: YAMAMORI SEIJI
IPC: B41J2/015
Filed: 1989-08-04
Abstract: PURPOSE:To make compact an ink jet head by providing opening/closing means provided in an ink passage for coupling an ink vessel to an ink discharge port, and means for pressurizing ink by pressure gas, and forming the opening/closing means of a shutter member having an opening, and a shape memory alloy for driving the shutter member in response to a record signal. CONSTITUTION:After ink is filled in a whole ink passage to an ink discharge port 3, pressure ink is supplied to an ink passage 110 at the ink reservoir side from a shutter member 8. When image signals 6 are applied to both ends of a shape memory alloy member 7, the member 7 us heated, and when it reaches to a martensite transition point, it tends to return to its original shape, thereby pulling up the member 8. In this case, when a pinhole 10 provided at the member 8 reaches the passage 110, the pressure ink is discharged from the port 3. Then, after the signal is applied, the member 7 is cooled by the member 7, and when it is cooled to a martensite transition point or lower, the member 8 is returned by the recoiling force of an elastic member 9 to close the pinhole 10. Since, many nozzles each having simple structure are arranged in high density the structure is simplified and made compact.

Title: Discharge electrode
Inventor: KOIWA ICHIRO
IPC: H01J17/49
Filed: 1990-07-31
Abstract: PURPOSE:To relax or solve the problem of discharge concentration without using mercury by providing conductive particles in a binder having insulating properties in such a manner as dispersing the particles therein, and also causing dielectric breakdown of the binder so as to form an electrode current path. CONSTITUTION:A discharge electrode 24 comprises a binder 24b which has insulating properties, conductive particles 24a provided in such a manner as being dispersed in the binder 24b, and an electrode current path 26 formed when dielectric breakdown of the binder 24b takes place. The dielectric breakdown easily occurs between adjacent conductive particles aligned in the direction along the direction of an electric field but is hard to occur between adjacent conductive particles aligned in other directions. Therefore the electrode current path 26 is easily formed along the direction of the electric field but is hard to be formed in other directions. As a result, current flow through the discharge electrode 24 becomes anisotropic. The discharge electrode 24 which thus has anisotropy in its current flow is suitable for constituting the cathode electrode 14 of a gas electric discharge panel and a gas electric discharge panel which can have a long life without sealing mercury therein can be formed.

Title: Hologram combiner and head up display using the combiner
Inventor: NISHIHARA TAKASHI
IPC: G02B5/32
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To make the peak of diffraction efficiency in peripheral parts smaller, to suppress ghost images and to make the intrinsic images to be reproduced easier to see by specifying the diffraction efficiency at the specific wavelength of the reconstruction diffracted light from a combiner to a specific value or below. SOLUTION: The diffraction efficiency at the wavelength exclusive of λ2/(n×T) before and behind a central wavelength at which the diffraction efficiency of the reconstruction diffracted light from the combiner is maximized is confined to <=2% when the thickness of a photosensitive material is defined as T, the refractive index of the photosensitive material as n and the central wavelength of the diffracted light of a hologram as λ. The spacings between the adjacent peaks of the small diffraction efficiency visible in the peripheral parts of the peaks are nearly λ2/(2×n×T) in the wavelength selectivity of the diffraction efficiency of the Lippmann holograms.  These phases vary respectively by π each between the adjacent peaks and, therefore, if two kinds of these Lippmann holograms are superposed, the adjacent peaks eventually overlap on each other. The peaks negate each other and the diffraction efficiency of the respective peaks in the peripheral parts is extremely diminished.
