Title: Parallel executing method for progressive radiosity
Inventor: YAKOBU REBISON
IPC: G06T15/80
Filed: 1995-04-11
Abstract: PURPOSE: To decentralize program codes efficiently by selecting preprocessing operation and a small projection section by a master node and performing actual ray tracing by a slave node. CONSTITUTION: The master node 8 receives screen drawing from a host computer 4 and preprocesses an object, namely, calculates various specific constants. The master node 8 sends the preprocessed object to slave nodes 7. At each node, complete screen drawing is present. The master node 8 joins a progressive radiosity loop and for each hemispherical projection, a small projection section is sent to the slave node 7. The slave node 7 traces respective rays up to a screen and sends the number of an object that rays strikes on back. The master node 8 calculates a shape coefficient from received object numbers. After the calculation, the light intensity of the screen is sent to the slave node 7 and final rendering can be started.

Title: Automatic focusing device for camera
Inventor: IDATE KIYOBUMI
IPC: G03B3/00
Filed: 1988-04-08
Abstract: PURPOSE:To correct dispersion in characteristics of distance measurement data and to accurately measure a distance by providing a position detecting means which detects the position of a focusing lens and making the characteristics of distance measurement data coincident with the characteristics of the output signal of the position detecting means to the subject distance. CONSTITUTION:A potentiometer is used as a focus sensor which detects the position of the focusing lens from the rotation of a motor 16. When the motor 16 rotates, the focus sensor 18 varies in resistance value. The variation in resistance value is converted into a voltage signal, which is outputted to an A/D converter 11 and converted into 8-bit data and outputted as a focus sensor value F to a microcomputer 7. The extension quantity of the lens 13 and the distance measurement data obtained from a PSD 5, on the other hand, are in the opposite relation from the distance, so the characteristics of the distance measurement data are converted and made coincident with the characteristics of a focus sensor value F, and then the motor 16 is controlled so that the converted distance measurement data is coincident with the focus sensor value F at all times, thereby accurately putting the focus lens 13 in focus.

Filed: 1978-07-14
Abstract: PURPOSE: To perform effectively decoloration, strilization, and denitrification by treating night soil deprived of hinderances for ozonization in advance by the combined used of ozonization and electrolysis.  
     CONSTITUTION: Original polluted water, e.g., night soil, etc., from the inflow distribution pipe 4 is sent to the floating zone 2, where suspensions present in original polluted water are buoyed up with the aid of the fine bubbles of hydrogen and oxygen given off between the anode 5 and the cathode 6 for removal. And the separated liquid is sent through the partition plate 14 to the electrolysis zone 3, where organics and nitrous acid ion present in the separated liquid are adsorbed and occluded by the granular active carbon 9 polarized by electrification in the zone 3. Afterwards, when ozone is jetted from the lower part of the active carbon 9, coloring matters and baceria present in the separated liquid are decolored and strilized, respectively. Thus, the effective purification of night soil, etc., can be attained with the combined use of coagulation and ozone-oxidation treatments.

Title: Logic gate
Inventor: MIYATAKE YUKIO
IPC: H03K19/003
Filed: 1988-04-08
Abstract: PURPOSE:To minimize the fluctuation of a delaying time for the fluctuation of the threshold voltage of an MESFET by obtaining circuit constitution without a constant current source. CONSTITUTION:Ordinarily, a current to flow at MESFET, when it is used in a saturated condition, and it is expressed that a threshold voltage is VT and a potential difference between gate sources is VGS, is in proportion to (VGS-VT)<2>. In such a case, since MESFET, which is a constant current source, short-circuits a gate and a source for the fluctuation of the threshold voltage, a potential difference VGS between gate sources becomes zero and a current to flow is fluctuated by VT<2>, the times required for charging and discharging are widely fluctuated as the current quantity is increased and decreased. Then, by using MESFET 1 and 2 instead of the constant current source, an output impedance is reduced, the potential difference VGS is always obtained positively, and therefore, the gate is not influenced by the fluctuation of the threshold voltage so much.

Title: Control circuit for motor
Inventor: YOKOYAMA TOSHIO
IPC: H02P6/12
Filed: 1989-04-04
Abstract: PURPOSE:To eliminate wasteful power consumption by detecting the malfunction of a power switching element in an inverter in a state that the operation of an inverter is stopped, and stopping the power supply to the inverter. CONSTITUTION:If power switching elements 9-14 which are short-circuited exist in an inverter 2 even if all the elements 9-14 are set to OFF, voltages generated at connecting terminals 2a-2c to the inverter 2 of a motor 1 are largely deviated from the value of approximately 1/2 of the voltage applied to the inverter 2. Accordingly, when an operation controller 4 detects the voltage, power supply to the inverter 2 is interrupted. Thus, abnormal heating due to an overcurrent, unnecessary power consumption can be prevented.

Abstract: PURPOSE:To increase a rotation amount without increasing magnetomotive force by forming a plurality of movable small pieces of a movable iron piece, by providing a projection to a yoke edge part during return and by providing an interlocking means to the movable small pieces. CONSTITUTION:When a coil 3 is excited, a driving part 15 of a first movable small piece 13 is attracted to a first attracting part 11 and a driving part 17 of a second movable small piece 14 is attracted to a second attracting part 12, and the movable small piece 14 rotates together with the movable small piece 13 through projections 19, 19 while the movable small piece 13 rotates. When the movable small piece 13 comes into contact with the first attracting part 11 of a yoke 1, the driving part 17 of the movable small piece 14 comes near to the second attracting part 12 and attracted strongly; therefore, the movable small piece 14 continues to rotate alone and comes into contact with the attracting part 12. As a result, an operational part 18 of the movable small piece 14 moves more than an operational part 16 of the movable small piece 13, thereby increasing a driving amount and increasing contact pressure at the contact. Contact reliability can be improved in this way.
