Title: Head mounted type display
Inventor: SUGIYAMA KIWA
IPC: G02B27/02
Filed: 1996-04-02
Abstract: PROBLEM TO BE SOLVED: To obtain a head mounted type display made small in size and light in weight, having excellent image-formation performance over the wide angle of view, and further made excellent in cot performance by controlling light intensity in accordance with scanning so that light going toward an eyeball may be intensity-modulated. SOLUTION: The light from a collimator lens 3 is made incident on the crystalline lens 4 of the eyeball 5. At such a time, a dot image is formed on the retina 6 of the eyeball 5. When scanning is performed by a light source unit 10, the dot image is scanned on the retina 6 of the eyeball 5. A control means 14 receives image information from an input means 15 and the position sensor 11 of the unit 10, and calculates what position of an image position corresponds to a position obtained when a luminous flux from the unit 10 is condensed on the retina 6. Then, an intensity modulation means 12 is controlled so that the light intensity from the unit 10 may be the intensity at the calculated position. Therefore, wide visual field is observed by scanning even when the aberration of an optical system is not corrected over the wide visual field.

Title: Readout circuit for memory
Inventor: HONDA SHIGE
IPC: G06F5/06
Filed: 1988-04-01
Abstract: PURPOSE:To eliminate the need to judge the information storage state of a first-in first-out (FIFO) by supplying clock pulses to a CPU according to a signal being stored in the FIFO and reading the FIFO by the CPU. CONSTITUTION:While the CPU 3 reads information out of the FIFO 2, the FIFO 2 holds a signal (a) at L until the read of the information is finished. The signal (a) goes up to H after the read of the information is finished, so the CPU 3 sends out a read signal (d) again and when this signal is made to fall, a F/F 4 samples the signal (a) and holds this state. Consequently, the holding output (b) of the F/F 4 is inverted to L and an AND gate 5 turns off in response to cut off the supply of the clock pulses (e). The CPU 3, therefore, stops operating and enters a waiting state without reading the FIFO 2, and then maintains the waiting state until the FIFO 2 stores new information and lowers the signal (a) to L. Consequently, the storage state of the FIFO need not be judged.

Title: Current detection circuit
Inventor: ICHIHASHI JUNICHI
IPC: G01R19/165
Filed: 1994-04-19
Abstract: PURPOSE:To prevent that a detected current value is affected by the change of power supply voltage and to enhance the general-purpose properties to power supply voltage without lowering detection accuracy by connecting a current detection part and a constant voltage element supplying constant voltage to the current detection part to a DC power supply in parallel. CONSTITUTION:A constant voltage element Zener diode ZD forms constant voltage VZ regardless of the magnitude of the DC voltage V0 of a DC power supply 11 to supply the same to a current detection part 13. A detection current is flows in from a detection terminal to flow through a detection resistor Rs. At this time, the potential V11 of the reversal input part of a comparator 13A becomes the potential wherein Zener voltage VZ is divided by the bleeder ratio of resistors R11, R12. The potential V12 of the non-reversal input part of the comparator 13A becomes potential wherein the voltage VZ is divided by the bleeder ratio of the resistors R13, 14 after the voltage VZ is dropped by the resistor Rs. Therefore, if a signal is outputted when V11=V12 is set to a threshold value and the potential V12 exceeds the potential V11, the inflow of an overcurrent can be accurately detected even when power supply voltage is changed.

Filed: 1992-04-02
Abstract: PURPOSE:To achieve prewashing by hot water as much as possible and avoid the waste of water to the utmost if hot water is used by a method wherein the supply and discharge of a washing liquid are repeated while the temperature of the washing liquid is under a specified value and a shift is made to a prewashing process when the above operation is repeated specified times or the temperature of the washing liquid exceeds a specified value. CONSTITUTION:A liquid supply valve 20 in a controller 38 is opened to discharge a washing liquid by a temperature detection signal from a temperature sensor 21 when the temperature of the liquid is not above 45 deg.C. The discharging of the liquid is repeated until the temperature of the washing liquid exceeds 45 deg.C or the frequency N of the supply and discharge of the washing liquid exceeds 2. When the temperature of the washing liquid exceeds 45 deg.C, a shift is made to a prewashing process. On the other hand, when the frequency N of supplying and discharging the washing liquid exceeds 2, the shift to the prewashing is made. In this manner. the shift to the prewashing process after the temperature of the washing liquid is raised enables effective washing. When the temperature does not rise, the shift to the prewashing process is made thereby avoiding the waste of water to the utmost.

Title: Cushion-type pressure control valve
Inventor: AONUMA SABUROU
IPC: F16K47/00
Filed: 1984-04-21
Abstract: PURPOSE:To improve the durability and to simplify the maintenance of the piping, the conduit and the terminal machineries by providing a pipe for controlling flow in and out of fluid to a cushion section provided in the body. CONSTITUTION:A piston 3 associated with a disc 2 and a cushion section 4 are provided in the body 1, while the opposite ends of the body are threaded to facilitate piping. The fluid will flow from the upper portion to the lower portion. Upon stoppage of flow, the pressure at the lower portion will exceed temporarily over that at the upper portion because of the inertia of fluid. Assuming the area of disc 2 is S1 while the area at the lower portion of piston is S2, differential force between F2XS2 and F1XS1 will function onto the piston 3 to move it upward. Here, the flow of fluid from the body of the cushion section 4 to the outside is controlled thus to control the moving speed of piston.

Title: Racing and slipping detecting system for vehicle
Inventor: TOYODA EIICHI
IPC: B60L3/10
Filed: 1987-04-03
Abstract: PURPOSE:To improve the detecting sensitivity of the racing and/or slipping of a vehicle, by a method wherein the judgement standard of the racing and/or slipping of the vehicle is set automatically on the basis of the output as well as the speed of a motor and the load of the vehicle. CONSTITUTION:The output power of a motor is obtained by a motor output operating unit 5 by a method wherein the product of outputs of a motor current detecting unit 3 and a motor voltage detecting unit 4 is multiplied by the power factor and the efficiency of the motor. This output is divided by the weight of a vehicle detected by a load detecting unit 8. Further, the result of the division is divided by a vehicle speed obtained by a motor speed detecting unit 1, whereby the acceleration or deceleration of the vehicle under a viscous condition is obtained. A vehicle racing and/or slipping set value operating unit 6 sets the judgement standard of the racing and/or slipping while incorporating the error of detection into the result of the dividing operations. A comparative operating unit 7 compares the output of the set value of racing and/or slipping with the actual accelerating or decelerating speed of the motor and outputs a vehicle racing and/or slipping signal.
