Title: Mca radio communication equipment
Inventor: HIRANO TADAHIKO
IPC: H04W84/08
Filed: 1984-08-06
Abstract: PURPOSE:To save automatically power consumption at standby by receiving a time slot location of a dummy frame signal from an MAC control station and interrupting the power of a reception circuit when the location is a scheduled dummy frame signal location. CONSTITUTION:When a power is applied, an oscillator 10 generating a clock pulse being a reference signal is operated and FF groups FFG#0-FFG#3 are operated, but since an FFG#4 is not synchronized yet, the level is ''0'' and a terminal P0 of the 2nd frame signal location identification circuit 11 is kept active. Thus, a switch 12 is operated and the system is at standby state. When a dummy frame number given to a frame signal received by a reception circuit 2 is coincident with a value of the pulse number counted by the FFG#0-FFG#3, the circuit 11 turns off the switch 12 to interrupt the power to a prescribed circuit thereby reducing the power consumption at standby. In this case, the synchronism is preserved by the operation of the FFG#0-FFG#4 and the switch 12 is closed at a point of time when the 2nd frame signal is received.

Abstract: PURPOSE:To prevent both the first and the second diode from being destroyed even if an instantaneous discharge occurs between high voltage and earth by having a protecting diode provide the cross section of a semiconductor chip with a specified area so as to control the amount of current destruction resistance in a required area. CONSTITUTION:In a protecting diode 5A comprising the first diode 5b and the second diode 5a connected in series with both ends of a capacitor 3 in a contrary polarity each other, the cross section of a semiconductor chip which constitutes the first diode 5b and the second diode 5a is set to be 1.7<=S<=2.0mm<2>.

Title: Light-receiving/emitting device, light-receiving/emitting device array, and manufacture of light-receiving/ emitting device
Inventor: NOBORI MASAHARU
IPC: H01L27/15
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To enable realization of a desired light emission quantity or light receiving quantity even in the case where the plane area of a lightreceiving/ emitting portion is reduced in comparison with the conventional technique, by constituting the light-receiving/emitting portion using a P-N junction having an uneven junction interface. SOLUTION: In a P-N junction 15, PN junction portions 15ya, 15yb on both sides of a band-shaped shallow junction portion 15x are regions having a greater junction depth than other regions. Therefore, the PN junction 15 having an uneven junction interface formed by the regions 15ya, 15x and 15yb is constituted. Thus, the junction area per unit plane area is increased. Accordingly, when a light emission quantity similar to that of the conventional technique is to be obtained, the plane area of the lightemitting portion may be reduced in comparison to the conventional technique. Therefore, light-emitting portions may be arrayed at a high density in constituting a LED array, and a desired light emission quantity may be obtained without increasing the dimension in a second direction of the LED.

Abstract: PURPOSE:To reduce the size and the weight of a bed drive controller by using a 3-phase induction motor for a drive motor of a medical bed unit, rectifying and smoothing single phase AC power source, and then operating with the output of an inverter which outputs 3-phase AC voltages.
