Title: Input protection circuit of semiconductor device
Inventor: SAWADA MASAHIKO
IPC: H01L27/06
Filed: 1986-02-28
Abstract: PURPOSE:To obtain a sufficient protection capability against an electric stress of any time-constant, by providing a diffusion input protection resistor with parasitic distributed diodes, and connecting a polysilicon resistor between an input terminal and the diffusion input protection resistor. CONSTITUTION:A polysilicon resistor 5 is connected between an input terminal 1 and a diffusion input protection resistor 2, the other terminal of which is grounded via a pull-down diode 3. When are electric stress biasing the pull-down diode 3 or pull-up diodes 4 in the forward direction is applied on the input terminal 1, the polysilicon resistor 5 operates so as to limit a current. The total resistance of an input protection circuit may be sufficiently maintained by the polysilicon resistor 5 and the diffusion input protection resistor 2, so that the resistance value of the polysilicon resister 5 may be of small value. Consequently, a sufficient protection capability can be obtained, without enlaging the chip size of a semiconductor device or decreasing is integration density.

Title: Radio receiver
Inventor: ISHIBASHI KAZUAKI
IPC: H04B1/16
Filed: 1990-02-26
Abstract: PURPOSE:To eliminate the need for manual operation for readjustment of sound volume by the listener when a selected station is changed by detecting the level of an audio signal for a prescribed time when an SD signal level exceeds a prescribed value after the selection of station is changed, detecting the peak level, comparing the preceding peak level with the detected peak level and making both coincident with each other. CONSTITUTION:The level of the audio signal for a point A is detected for a prescribed time t1 and a peak level X in the detected level is detected after the lapse of a prescribed time t1. Then a CPU compares the both by discriminating whether or not the relation of Y=X is satisfied between the detected peak level X and the peak level Y detected precedingly. When the relation of Y=X is satisfied, since no sound volume adjustment is required, a zero level (0) is outputted to an electronic volume as a control signal. When the relation of Y=X is not satisfied, a sound volume correction data alpha is calculated to adjust the sound volume level so that the relation of Y=X is satisfied, the level X is replaced into the peak level Y for the preparation of the succeeding measurement and the calculated alpha is outputted as a control signal. Thus, the sound volume is automatically corrected.

Abstract: PROBLEM TO BE SOLVED: To reduce power consumption, to facilitate gradation display and to provide images of high precision and image quality by installing a ferroelectric layer such that its polarized condition is controlled by a selected display signal and the polarized condition drives the liquid crystal. SOLUTION: This device is provided with a selecting means which selects a display signal and a ferroelectric layer 2 which drives the liquid crystal by the state of polarization controlled by the selected display signal. A TFT1 is used as a selecting means. In this case, the gate of the TFT1 is connected with a scanning line 4 and the source-drain is interposed between a signal line 5 and the ferroelectric body 2. The display signal is required to give a change in the condition of polarization, but its specific waveform is not required. The display signal does not necessarily need polarity inversion but polarity inversion is desirable from the viewpoint of burn prevention.

Title: System stopping system for controller system
Inventor: HARA HIDEYUKI
IPC: G05B15/02
Filed: 1991-03-11
Abstract: PURPOSE:To surely protect the stored content of a RAM by executing a real system stoppage after the completion of an access processing to data. CONSTITUTION:When a power source switch 3 is interrupted, or an initializing command is inputted by using a keyboard or the like, a monitoring task is activated, and a system stopping request is transmitted to each application task. Then, at the time of executing the access of the data to an RAM 9, each application task is moved to a stopped state after executing only the access to one pertinent data. Also, when the access to the RAM 9 is not executed, each application task is smoothly moved to the stopped state. Moreover, the monitoring task outputs a system reset command after confirming the completion of the access state of each application task. Therefore, the access operation can be prevented from being stopped during the access of the data to the RAM 9.

IPC: G01P15/00
Filed: 1995-03-06
Abstract: PURPOSE: To visually detect whether prescribed impact is impressed with simple constitution by providing a bar-shaped elastic body and a triangle pole-shaped projection for the adjusting window of a crystal oscillator. CONSTITUTION: At normal time, the elastic body 2 is curved from a center line end is held by the triangle pole-shaped 5 projection provided at the end of the adjusting window 1. At that time, elastic force which is to restore to the original position of the center line operates on the elastic body 2. Such a function can be obtained by using a reef spring as the elastic body 2, for example. When the impact is impressed on the crystal oscillator from outside, the elastic body 2 oscillates by a spring 3 fitted to the tip and it is restored to the original position (center line)by jumping a triangle pole 5. Thus, that the impact more than a standard is added can be detected. The spring 3 is fitted to the tip of the elastic body 2 and it moves the elastic body 2 in a vertical direction.  The elastic body 2 moves by oscillation added to the crystal oscillator and the presence or absence of holding by the triangle pole 5 can be decided.
