Abstract: PURPOSE:To compensate fluctuation of the light source without including the error due to the difference of average reflection factor in the integral sphere and without requiring the same standard materials, by using a part of the inside face of the integral sphere itself in stead of standard materials. CONSTITUTION:The light from light source L is inputted to integral sphere I through light incident window In, and lights emitted from emitting window Ou, which is in the position opposite to sample (s), and emitting window Ou', which is in the position opposite to a point off from sample (s), are incident to spectroscope M through rotary chopper Y of three blades, semitransparent mirror H, and mirror X. The light emitted from spectroscope M is inputted to signal processing circuit Z through photodetector D and preamplifier A. Switches SW1 and SW2 are switched while interlocking with chopper Y, and outputs corresponding to light fluxes Fs and Fst are held in capacitors K1 and K2. The output of capacitor K1 is stored in memory Me through the A-D converter, and the output of capacitor K2 is fed back to photodetector D through boosting DC-DC converter D-D. As a result, the influence of fluctuation of the light source is prevented.

Title: Liquid crystal display device
Inventor: MURATA YUKIO
IPC: G02F1/133
Filed: 1989-02-07
Abstract: PURPOSE:To hold the contrast of a liquid crystal display unit invariably constant against ambient temperature variation by cascading diodes whose voltage drop has a negative characteristic to temperature to the earth terminal of a three- terminal power circuit used as a liquid crystal display unit driving circuit power source. CONSTITUTION:The diodes 2 and 3 are connected between the earth terminal of the three-terminal power circuit 1 and the ground and a diode 4 prevents a current from flowing backward from a backup capacitor 5.

Then a liquid crystal display unit driving circuit 9 is connected to the voltage terminal 8 and the liquid crystal display unit 10 is driven to make a display. Consequently, the invariably constant contrast can be held against temperature variation by specifying the display contrast temperature characteristic of the liquid crystal display unit 10.

Title: Target change gear ratio generating device for continuously variable transmission
Inventor: ADACHI KAZUTAKA
IPC: F16H61/04
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To perform change gear ratio control appropriately without generating overshoot so as to improve fuel consumption and operability by computing deviation between an arrival change gear ratio and a target change gear ratio, and determining a dynamic characteristic constant for computing the target change gear ratio and a command change gear ratio according to the deviation. SOLUTION: In a target change gear ratio generating device 400 inputting output signals of sensors 301, 306, the target input rotating speed of a transmission is first computed from vehicle speed and throttle opening in order to obtain an arrival change gear ratio. This target input rotating speed is divided by the output rotating speed of the transmission to compute the arrival change gear ratio, and then a dynamic characteristic constant (time constant) of a change gear ratio to be a target at the time of making the dynamic characteristic of the change gear ratio to be the target coincide with the arrival change gear ratio is determined according to change gear ratio deviation between the arrival change gear ratio and the change gear ratio to be the target.  The target change gear ratio and a command change gear ratio is then computed by an inverse system of the arrival change gear ratio, the dynamic characteristic constant of the change gear ratio to be the target and the dynamic characteristic of a change gear ratio servo device to establish a requested change gear ratio.

Abstract: PURPOSE:To integrate a circuit without enlarging an optical circuit and to obtain an optical integrated circuit without increasing a light loss and excellent in circuit characteristic by providing first and second core layers and optically coupling both layers in the vertial direction where the patterns of the layers are partly in line with each other. CONSTITUTION:A quartz layer formed on a substrate 1 is dry-etched and patterned in a specified shape to form two lower core waveguides 2 (first core layer). A quartz layer having a higher refractive index than the lower clad layer 3 is formed on the layer 3 and dry-etched and patterned in a specified shape, and an upper core waveguide layer 4 (second core layer) having a pattern partly in line with the pattern of the layer 2 is formed. Since the layers 2 and 4 are optically coupled in the vertical direction where the patterns of the layers are partly in line with each other, the waveguides are formed on the same substrate plane, and the area occupied by a unidirectional coupler on the substrate is reduced.

IPC: H01B12/06
Filed: 1993-02-16
Abstract: PURPOSE:To obtain a superconducting coil of a high critical temperature and a high critical current density in a magnetic field by forming a superconducting oxide layer whose thickness is greater in its center than in peripheries. CONSTITUTION:A superconducting coil is formed of an oxide series superconductor layer 1 on an insulated substrate 2 made of an alloy of silver, gold or nickel. The oxide superconductor layer is thicker in the center than in the peripheries. When it is specified that the critical current density at a very small part of the superconductor coil is DELTAJc and the area of the very small part is DELTAS, the thickness of the inner part of coil and that of the outer part of coil are changed so that DELTAJcXDELTAS may be constant. The oxide series superconductor must be mainly composed of (Y, Ba, Cu, O), (Bi, Sr, Ca, Cu, O), (Tl, Ba, Ca, Cu, O) and (Tl, Pb, Sr, Ca, Cu) and contains La, Nb or the like when used. This construction makes it possible to limit the degradation of characteristic resultant from ununiformity of the magnetic field of the coil.

Title: Snow melting machine
Inventor: KAMO YOSHIAKI
IPC: E01H5/10
Filed: 1993-02-16
Abstract: PURPOSE:To make it possible to move a snow melting machine on a slanting surface or facilitate snow melting work by dividing the internal part of a snow melting tank into a burner chamber and a snow melting chamber slanting the bottom of the tank and mounting a movement wheel to an axle receiver in the lateral part. CONSTITUTION:Movement wheels are laid out near the central part of the bottom of a snow melting tank where the body of a snow machine is supported with the movement wheels and the lowest part of the snow melting tank 2, thereby constituting a normal flowing water slope area. Ground snow melting work is facilitated by fixing the body in this state. When moving, a steering handle is restrained while the opposite side of the snow melting tank 2 is raised, centering on the movement wheels. This way enables the snow melting machine to be moved by person with two wheels supported, When the machine is buried for permanent service, the wheels are removed and the whole body of the snow melting tank 2 is buried, thereby forming a buried snow melting machine.

Abstract: PURPOSE:To attain the parallel processing operation and to ensure a fast access to an exclusive fetch by performing only the access control of a memory array part via an access control part and executing the acceptance and interpretation of a CPU request via a request acceptance part for the access control part. CONSTITUTION:The access request of each CPU stored in a buffer 12 is accepted by a request accepting part 18, and this part 18 gives a request to an access control part 16 for the control of access for each CPU. A means 20 of the part 18 checks whether an access request is stored in the buffer 12 from the CPU or not. When a fact that a request for storing an exclusive fetch is confirmed, a means 22 gives a request to the part 16 for the access control. When a means 24 confirms that by a CPU 10 having an access request to the exclusive fetch, an access request to update the data on a lock area is stored into the buffer 12, the means 24 requests the part 16 to update the data and to cancel the lock of the area. As a result, a fast access is ensured to the exclusive fetch.
