Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To prevent the condition of an integrated circuit having elements formed at semiconductor devices from being observed by optical means, by forming steps of specified size with fine grains on the surface of a protective film. SOLUTION: A protective film 14 has a mean surface roughness of 2 μm or more with fine grains 14a on the surface.

Title: Magnetic bubble driving circuit
Inventor: HAYASHI SHIGEO
IPC: G11C11/14
Filed: 1979-06-07
Abstract: PURPOSE: To eliminate the impulse noise by connecting the serial circuit of the capacitor and the resistance in parallel to the coil of the serial resonance circuit.  
     CONSTITUTION: Coil L and capacitor C forming a resonance circuit are connected in series to the joint of two transistor switches QP and QN. Furthermore, capacitor C' and resistance R' connected in series each other is connected in parallel to the coil. When the voltage of ±E is applied to the resonance circuit alternately via switches QP and QN, the sine wave current flows to the resonance circuit. And the impulsive voltage of the output voltage of the coil driving circuit is attenuated so much so that it can be ignored in terms of the practical use by the serial function of capacitor C' and resistance R' which are connected in parallel to coil L. As a result, the clamping circuit for voltage protection of the switch transistor of the driving circuit can be omitted.

IPC: H04M1/72508
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To suppress power consumption by controlling a reception interval based on a reception state. SOLUTION: A microcomputer of a PHS fallen into a standby state reaches a reception state only for a time W1 at each 1.2 second to receive intermittently a control channel (PCH) (ST22-ST25, ST23). Furthermore, the microcomputer discriminates the reception state based on discrimination information in the reception state such as electric field strength and presence of error in received data at reception (ST27, ST33).  The microcomputer reaches a state of receiving the control channel for each 2.4 seconds when the reception state is excellent consecutively for a prescribed time in the state of receiving the control channel for each 1.2 second in the power save mode (ST33-ST35), and the microcomputer immediately reaches a state of receiving the control channel for each 1.2 second when the reception state is not excellent in the state of receiving the control channel for each 2.4 seconds (ST33, ST32). When an excellent reception state is consecutive in the standby state, the reception interval of the control channel is extended to reduce the power consumption.
