Title: Display panel driving device
Inventor: KINOSHITA HIROYUKI
IPC: G09G3/30
Filed: 1999-09-10
Abstract: PROBLEM TO BE SOLVED: To suppress precisely a situation where display irregularities are generated on a display panel, regardless of characteristics or driving conditions of the display panel. SOLUTION: An up-counter 12 counts the number of pixels emitting light during one horizontal scanning of an EL display panel, and outputs the count result as an addressing signal of an EEPROM 13.

Title: Solid laser device
Inventor: TANUMA RYOHEI
IPC: H01S3/08
Filed: 1993-10-15
Abstract: PURPOSE:To prevent the deterioration of efficiency due to the formation of a non-oscillation region by a solid laser at the time of a large hole diameter, and to enable laser oscillation having small thetad under wide operating conditions by forming the transmitting section of holed mirror as an output mirror for reducing thetad in a high transmittance section having small reflectivity. CONSTITUTION:A total reflection mirror 2 is arranged on one side of an Nd: YAG slab 11 and hold mirror 3 on the other side as an output mirror, and a beam expander expanding laser beams 6 toward the direction of the slab while interposing a convex cylindrical lens 41 and a concave cylindrical lens 51 is formed between the slab 11 and the output mirror 3. In the holed mirror 3, a high reflecting surface is formed on the peripheral section 32 of the surface of a glass substrate through coating, and a residual central section is formed in a transmitting section 31. Accordingly, when the hole section 31 slightly has reflectivity, laser beams 6 slightly remain even after they hit into the hole 31, thus preventing the deterioration of efficiency due to the formation of a non-oscillation region.

Title: Apparatus for controlling liquid pressure in eyeball
Inventor: SHII DEII ARUMENDEADESU
IPC: A61B5/022
Filed: 1988-10-14
Abstract: PURPOSE: To maintain intraocular pressure within a safe level by receiving a signal form a pressure detection means to control the amount of liquid corresponding to changes in intraocular pressure. CONSTITUTION: A pump 122 circulates liquid at a specified flow rate when a signal from a transducer is within a specified range. The flow rate is operated so that the pressure in the eyeball 130 detected by this device I is maintained at a specified value. When a pressure decrease is detected by the device, the pressure signal for a microprocessor controller increases the speed of the pump 122 and circulation pressure of physiological saline solution. A fixed flow limiter 124 increases the amount of circulating physiological saline solution drawn to a tube 138. This makes up the physiological saline solution returning to the eye 130. Conversely, when an increase in the intraocular pressure is detected, the pump speed slow down, decrease the back pressure and flow rate through the limiter 124. Liquid flow to the tube 138 almost stops, resulting in pressure decrease in the tube 138, and net outflow of liquid from the eye 130.

IPC: F02B63/04
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To improve the degree of freedom in the setup position of a generator to be connected to an engine, in a small ship. SOLUTION: An engine 20 in an engine room 4 and an electromagnetic clutch equipped in a hydraulic pump 53 are connected to each other by a belt 51, and a hydraulic motor 54 set up at the outside of the engine room 4 and the hydraulic pump 53 are connected via an oil passage 58. A generator 55 is connected to this hydraulic motor 54 via a flexible coupling, so this generator 55 can be set up in place anywhere it may be, upon avoiding any direct connection between the generator 55 and the engine 20. A sudden variation in hydraulic pressure is checked by an action of the electromagnetic clutch, and thereby any adverse effect is not given to the generator at all. In addition, hydraulic operating fluid in the oil passage 58 is cooled by a cooling water pump 65 using this generator 55 as a power source, thereby promoting the stabilization of hydraulic pressure.

Filed: 1985-11-19
Abstract: PURPOSE:To sharply reduce the weight of an optical head and to speed up the access time, by inclining a guide rail by a fixed angle in corresponding with the deflection angle of a recording medium. CONSTITUTION:Under a condition where the vicinity of the outer peripheral surface of a disk-like recording medium 31 is deformed to a parasol shape having the deflection angle A1 of about 0.2 deg. due to a change with the lapse of time and the self-weight, a guide rail 36 which moves an optical head 34 is disposed in such a way that its own deflection angle A2 can become almost the half (0.1 deg.) of the deflection angle (0.2 deg.) of the recording medium 1. Therefore, the inclination C1 between the optical axis B of the optical head 34 and nondeformed section of the recording medium 31 becomes about 0.1 deg.. Moreover, the inclination C1 of the part which is deformed to a parasol shape in the vicinity of the outer peripheral surface to the optical head 34 can be adjusted to about 0.1 deg. and the perpendicularly intersecting relation between the optical axis B of the optical head 34 and disk-like recording medium 31 can be maintained under a condition where reproduced signals hardly decline.

Title: Binary coding circuit for image signal
Inventor: SAWADA MITSUSHI
IPC: H04N1/403
Filed: 1984-12-08
Abstract: PURPOSE:To reproduce a single thin line and a high-density pattern with a high space frequency by composing a binary coding circuit of a peak holding circuit which holds the peak value of an image signal, two comparators which convert an analog signal into a binary signal and have different slice levels, two slice level generation parts, an image signal comparing circuit, and a selector. CONSTITUTION:An image signal read by an image pickup element 10 is amplified by an amplifier 1 to a specific level. The amplified image signal is led to the peak holding part 2 and comparators 3a and 3b. The peak holding part 2 holds the peak value of the image signal and the peak level is divided to generate slice levels S1 and S2, which are used as reference voltages of the comparators 3a and 3b. Consequently, the output of the comparator 3a is as shown by (a) and the output of the comparator 3b is as shown by (b). Those signals (a) and (b) are compared with each other to select (a) when (a) and (b) are equal, (b) when (a) and (b) are different and (a) is at 'H', or (a) when (a) is at 'L'. Consequently, the signal (a) at a part A, the signal (b) at a part B, and the signal (a) at a part C is selected to obtain (c), thereby reproducing both the high-density pattern and thin line.

Title: Fault detector circuit for charger
Inventor: KUBO HIRONORI
IPC: H02J7/00
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To detect and protect a short-circuiting fault of a charging circuit in a short time, by comparing a voltage specified value changing according to a time from starting charging with a detected voltage of a DC circuit of a power converter, and deciding the fault if the detected value is lower. SOLUTION: A DC voltage detected value Vdc of a DC circuit detected by a voltage detector 10 is compared with a voltage specified value VL (an output of a voltage specified value generator 2) by a DC voltage discriminator 1. If Vdc<VL, a fault of a charging circuit is decided. For example, if the DC circuit is short-circuited so that the DC voltage detected value is a waveform like Vdc2, Vdc<VL is obtained at a time T2, and the fault can be detected. Since the value VL at a time T1 after a sufficient time is elapsed from ON of a main switch 5 is a detected value V1, wherein T1 is about several times as large as a charging time constant 0 and V1 is a detected value of the lowest DC voltage allowable at the time of establishing the DC voltage, when the DC voltage is not established, the fault can be detected.
