Title: Burn-in test circuit of semiconductor memory
Inventor: YONGUUKEUN CHIYOI
IPC: G11C29/50
Filed: 1993-09-24
Abstract: PURPOSE: To provide a burn-on test circuit suppressing the consumption of electric power, having no possibility of a malfunction, and having high reliability. CONSTITUTION: External signals fed to a semiconductor memory, i.e., RAS signal, CAS signal, and WE signal, are utilized, a short enable pulse EN is formed by a timing generator 60 and a sensor controller 70, the level of the power voltage Vcc is sensed while the short pulse EN is fed, and the power consumption in the stand-by state by a circuit during the burn-in/test mode such as a power voltage sensor 20 is eliminated during the normal operation other than the burn-in/test mode. The mode is changed to the burn-in/test mode when the external input signal state satisfies the specific WCBR condition and the external power voltage is larger than the burn-in voltage only, thus a malfunction caused by superposed noises can be prevented.

Title: Ball bumper
Inventor: KUWABARA OSAMU
IPC: A63F7/02
Filed: 1992-08-13
Abstract: PURPOSE:To improve durability against humidity, etc., and reliability by causing a ball to make contact with a detection plate to incline or move said plate and detecting the change of state of incident light reflected by a reflection mirror in association with the detection plate by means of a reflection type sensor. CONSTITUTION:If a ball 5 makes contact with a detection plate 4, the plate 4 is inclined with respect to a game base 2, whereupon an actuator 6 integral with the plate 4 and a reflection mirror 6a also are inclined. If the mirror 6a is inclined to a degree exceeding a predetermined range, a state of incident light reflected by the mirror 6a is changed with respect to a reflection type light sensor 7 disposed below the mirror 6a. This change of state, that is, a phototransistor of the sensor 7 no longer receives light, whereby inclination of the mirror 6a, i.e., inclination of the plate 4 is detected. As a result, contact of the ball 5 can be detected.

Title: Agc device
Inventor: HOUKAN SACHIKO
IPC: H03G3/30
Filed: 1987-09-25
Abstract: PURPOSE:To make the maximum output after a gain control larger than the time of a low area frequency in call of a high area frequency by providing a filter having a different frequency characteristic and an attenuator at a feedback to an AGC amplifier, changing a voltage value with a frequency band and executing the feedback to the AGC amplifier. CONSTITUTION:The low pass filter of a filter 6 and the high pass filter of a filter 7 are provided on the way of a feedback to an AGC amplifier 1. By classifying a low area frequency and a high area frequency, only the voltage of a high area frequency is attenuated by an attenuator 5. For such a reason, even in the same input voltage, the value of the voltage feed back to the AGC amplifier 1 can be changed by the high area and low area frequencies. Consequently, at the low area frequency in which the distortion is easy to ring in one's years, the output is suppressed to low, and at the high area frequency in which the distortion is brightly felt, the output can be generated to high.
