Inventor: WATANABE TOSHIOMI
IPC: G06T15/80
Filed: 1992-10-22
Abstract: PURPOSE:To decrease the calculation quantity at the time of image generation and to make shading representation possible without decreasing the processing performance of the existent simulateid visual field device. CONSTITUTION:The reflected light intensities of respective planes of a data base are computed by using a host computer 1 or other computers before a visual field begins to be simulated, and they are defined in the data base. Then when the visual field is simulated by an image generating device 2 on the basis of the data base, a shading generating process part 5 present in an image generating device 2 is used to calculates the color of a shaded plane from the product CiXId of the color Ci and reflected light intensity Id of the plane defined in the data base. Further, when texture mapping is carried out for the plane, the product ItXCiXid of It of a texture generating process part 4 and the output CiXId of the shading generating process part 5 is regarded as the final color of the plane to make a display on an image display device 3.

Title: Master machine for digital cordless telephone
Inventor: FUKUDA KUNIO
IPC: H04W16/14
Filed: 1994-12-13
Abstract: PURPOSE: To enable a slave machine to receive the control signals without interference even in the case of transmission of control signals from plural master machines at the same timing by interruptedly transmitting the control signal having a slot constitution at intervals of a certain time and omitting this transmission at random. CONSTITUTION: With respect to the control signal transmitted from a master machine, about 625μzsec control signal of one slot is transmitted at a prescribed timing T1 , and thereafter, the control signal of the next slot is transmitted at a timing T2 after about 5msec. This transmission at timings T1 and T2 is repeated with about 250msec period. At this time, the master machine omits transmission of the control signal at the timing T2 at random based on random numbers generated in a communication control part. When the slave machine enters into the reception waiting state, the slave machine interruptedly receives the control signal from the master machine with about 1.5sec period; and if it cannot acquire the control signal, it processes reception or the control signal at the timing T2 .  If it cannot acquire the control signal, it receives a control channel continuously for a prescribed time. Thus, the slave machine can receive the control signals without interference.

Abstract: PURPOSE:To measure brightness with a simplified circuit to reduce a cost by constituting a measuring device for light only of a photo diode for receiving an input flux and a CPU for processing photo-voltage output from the photo diode. CONSTITUTION:When an output from an Nch open drain transistor 35 changes from a GND level to high impedance, a timer in a CPU 1 is once reset and then starts so that a photo diode 32 discharges voltage of Vc stored in a capacitor 37 with photo current according an incident light amount, while an anode potential rises from the GND level along a slope according to the photo current and when it exceeds threshold voltage of a Schmidt-type inverter 36, an output of the inverter 36 is inverted. Thus time t0 from a time point t1 when the output of the transistor 35 changes to the high impedance to a time point t2 when the output of the inverter 36 is inverted from the Vc level to the GND level is measured by the timer in the CPU 1 to obtain photo current, that is, brightness.

Title: Solid horn for ultrasonic vibration
Inventor: TAMAKI FUMITAKA
IPC: B06B1/02
Filed: 1995-11-02
Abstract: PROBLEM TO BE SOLVED: To secure a desired displacement amplitude magnification and further to improve a joining strength without lowering a vibration transmission efficiency in a solid horn formed by joining different materials in the axial direction. SOLUTION: Different metallic materials are joined in the axial direction by friction welding to improve the joining strength to a practical level. This means that a thin and light horn capable of providing a smooth and even vibration system good in vibration transmission efficiency is obtained at a low cost without any stress concentration due to the change in cross-sectional area. Accordingly, a solid horn capable of increasing an amplitude is realized even by a rod having a uniform diameter. Further, when the cross-sectional areas are changed, a solid horn having a higher amplitude magnification is obtained.
