IPC: F23N5/12
Filed: 1985-11-25
Abstract: PURPOSE:To lengthen the service life of a dry cell without spoiling the sensitivity of detecting a flame by a method wherein an A.C. electric source, impressed on a frame rod for detecting the flame, is intermitted by a multi-vibrator oscillation circuit and the frequency of the oscillation is set within a specified period of time, in the safety device for combustion while is utilizing the dry cell as an electric source. CONSTITUTION:When a flame is formed in a burner section, an A.C. current, being impressed between a flame rod 6 and a burner 7, is added with the component of D.C. current generated by the rectifying effect of the flame. When the component of the D.C. current is detected, a transistor Q8 is put ON and an electric source is supplied to a solenoid valve circuit while a solenoid value 9 is attracted and held. Simultaneously, the electric source is also supplied to a multi-vibrator oscillation circuit 4 and transistors Q10, Q11 are put ON, OFF alternately, When the frequency of oscillation is set so that the transistor Q11 of the multi-vibrator oscillation circuit 4 is put On before the charge of a capacitor C5 is discharged through resistors R12, R15, the supply of electric current for a blocking oscillation circuit 5 is effected intermittently and a safety device may be operated without any trouble even when the supply of electric current is reduced to 1/2-1/3 of conventional supply of the electric current.

Abstract: PURPOSE:To improve the rigidity of a car body frame by extending a bracket for supporting a foot rest from the upper part of a main pipe to right and left over a battery to fit the bracket to the main pipe freely to be disconnected. CONSTITUTION:Box receivers 27 are fixed to a main pipe 13 through each stay 28 extended downward from the main pipe 13. A battery box 23 is supported by the box receivers 27 freely to turn. Furthermore, since plate-like brackets 32 for supporting foot rest are fitted to stays 30, 31 extended upward from the main pipe 13 freely to be disconnected, the upper opening of a battery box 26 is opened by removing the foot rests and the plate-like brackets 32. A battery 25 can be therefore fitted and disconnected to/from a car body from the upper. Since members for supporting the box receivers 27 can be formed at a required minimum length by using the stays 28, the increase of weight is restricted and the rigidity can be secured.

Title: Manufacture of semiconductor device
Inventor: NOMURA SHIGEHIKO
IPC: H01L21/265
Filed: 1993-09-28
Abstract: PURPOSE:To prevent a state that fragments which are stripped from the outer circumferential part of a semiconductor wafer during a heat treatment adhere again to a semiconductor device by a method wherein the semiconductor wafer is heat-treated while the semiconductor wafer is protected by using a wafer support jig having a tilted slit in such a way that a semiconductor-device formation face on the semiconductor wafer is directed obliquely downward. CONSTITUTION:When a semiconductor wafer 1 on which a thin film 2 has been formed by a spin coating method is manufactured, the semiconductor wafer 1 is held by using a wafer support jig 7 provided with a tilted slit 8 in such a way that a semiconductor-device formation face 3 on the semiconductor wafer 1 is directed obliquely downward. By this method, when the semiconductor wafer having the thin film formed by the spin coating method is heat- treated, the semiconductor-device formation face 3 on the semiconductor wafer 3 is kept obliquely downward. As a result, even when fragments of the thin film 2 cracked by a thermal stress are produced, they fall vertically downward, and it is possible to avoid a state that they adhere again to a semiconductor device.

Title: Method for detecting breadthwise bar-shaped intermediate part on commodity surface
Inventor: KONDO MICHIO
IPC: H01R43/06
Filed: 1991-09-13
Abstract: PURPOSE:To surely detect a breadthwise bar-shaped intermediate part on a commodity surface while almost unnecessitating the sensitivity correction of a sensor and to other control. CONSTITUTION:A detected object is irradiated with spot light while feeding it at a fixed pitch, the measured value of reflected light is sampled synchronously with the feeding pitch and when the sampled measured value is larger than a reference value, the number of feeding pitches are started being counted. Afterwards, when the measured value is smaller than the reference value, the count value at that time is preserved as a bar width value and after that, a reverse feeding operation is started and until the measured value is larger than the reference value after the operation is started, the number of pitches is preserved as a backlash component. When the measured value is smaller than the reference value, the direction is changed into a positive direction and after first feeding the backlash component and next feeding the half of the bar width value, the position becomes the breadthwise intermediate part of the barshaped part.
