Title: Absolute bearing measurement device for object travelling at low speed
Inventor: FURUKAWA KAZUYOSHI
IPC: G01C15/00
Filed: 1993-07-21
Abstract: PURPOSE:To measure absolute bearing on a real time basis, and make a sensor section compact and energy-saving type by resetting the displacement angle of a rotational angular velocity sensor to the absolute bearing measured with a bearing sensor, when angular velocity is equal to or less than the prescribed value. CONSTITUTION:When angular velocity detected with a rotational angular velocity sensor 3 is equal to or less than a reference value OMEGA, the bearing change of an object 1 is fine and the travel speed thereof is low. At the same time, a bearing sensor 2 is approximately stationary and the measurement result thereof is reliable. Thus, when angular velocity (drift) again detected after eliminating offset to keep the angular velocity of the sensor 3 at zero, is equal to or less than the reference value OMEGA, the measurement of absolute bearing with the sensor 2 starts, and measurement data available therefrom is, then, taken as initial measurement data about the displacement angle of the sensor 3. Thus, the displacement angle measured with the sensor 3 is free from an effect of measurement errors so far accumulated, and represents the absolute bearing on a real time basis, because of initialization with the data of the sensor 2.

Title: Semiconductor laser
Inventor: HATA TOSHIO
IPC: H01S5/00
Filed: 1986-07-30
Abstract: PURPOSE:To decrease the thermal resistance of semiconductor laser and to improve reliability, by forming a second clad layer so that the thickness of the part approximately corresponding to the light emitting region of an active layer is thick and that of the part corresponding to the part other than the light emitting region is thin. CONSTITUTION:A stripe-shaped current constriction structure is provided on a substrate 1. A double heterojunction type multilayered crystal comprises a first clad layer 3, an active layer 4 and a second clad layer 5. In this semiconductor laser, the thickness of the second clad layer 5, which is formed at a place other than a light emitting region 17 of the active layer, is made thinner than the thickness of the second clad layer 5, which is formed at a place approximately corresponding to the light emitting region 17. For example, the N-type GaAlAs clad layer 5 formed on the P-type GaAlAs active layer 4 is selectively etched with photoresist and the like as a mask. Thus the place approximately corresponding to the light emitting region 17 is shaped in an inverted V shape. Thus, the heat, which is generated in the vicinity of the light emitting region of the active layer is efficiently dissipated in a heat sink, and the reliability of the semiconductor laser can be improved.

Title: Bus control system
Inventor: SHIBUYA HIROYUKI
IPC: G06F13/42
Filed: 1984-08-31
Abstract: PURPOSE:To improve efficiency of transfer by installing a bus control means between a bus master and a transfer destination device and changing over both transfer requests in accordance with a synchronizing or a non-synchronizing transfer request sent from the bus master. CONSTITUTION:When data from a host computer are accumulated at a buffer 15 to some extent, directly in a memory access (DMA) procedure, a bus-leased request RQ at a timing generating circuit (TGC) 13 is sent to a bus control means, so that the device can not be occupied. A control means 7 returns a bus-use permitting signal (GR) to TGC 13. When a transfer destination of a signal which obtains a bus is RAM, TGC 13 decodes an address with a decoder 12 and sends a synchronizing data transfer request. When a transfer destination is not RAM, sending is executed to TGC 14 as a non-sycnchronizing request, and starting is applied so that an address strobing AS and an data strobing DS may be issued. These AS and DS are sent through a control bus to the transfer destination. At the time of the non-synchronizing request, the data ACK from the transfer destination are inputted to TGC 14.

Title: Driving method of plasma display panel
Inventor: NAGAOKA YOSHIMASA
IPC: G09G3/288
Filed: 1999-06-25
Abstract: PROBLEM TO BE SOLVED: To obtain a driving method, which prevents mallighting of a non- turned on cell, by providing a first discharging process that applies a specific voltage between first and second electrodes. SOLUTION: A low Vfe non-turned on cell is normally in a condition in which no wall electric charge exists because no maintaining discharge is conducted during a maintaining discharge period. However, there is a case in which slight amount of wall electric charges exists by the effect of discharges made by the turned on cells located at the top and the bottom and the right and the left of the non-turned on cell. OC pulses have a positive pulse to be applied to an X electrode and a negative pulse to be applied to a Y electrode. The applied voltages are set not to exceed a discharge starting voltage. However, the voltages are added by residual wall electric charges at the completion time of the maintaining discharge period.  If the amount of finite wall electric charges is large, the potential between the electrodes exceeds as discharge starting voltage, discharges take place by the OC pulses and wall electric charges are formed. At that time, the cell has approximately the same wall electric charges of a normal turned on cell. Therefore, a complete erasing is conducted by the erasing discharge in a rest period later.
