Title: Roller breaking detection method of roller house kiln
Inventor: AOKI MICHIRO
IPC: C21D9/00
Filed: 1989-08-29
Abstract: PURPOSE:To surely detect the breaking of each roller by properly arranging the phase of a semicircular-cross section shade body to attach to the driven end of each roller and setting two groups of light projecting and receiving devices on two lines getting an unobstructed view of a point which sandwiches the rotation center of each shade body to pass a beam of light. CONSTITUTION:Each roller 1 is normally rotated without breaking to properly arrange a phase so that a semicircular-cross section shade body 3 attached to the driven sides of the rollers 1 alternately may block upper and lower beams of light at regular cycle intervals and output of light receiving devices 5, 5 is switched on and off at regular cycle intervals. But since either of the rollers 1 is broken to stop the shade body 3 of the roller, the beam of light is blocked by the stopped shade body 3 to stop switching-on and off at regular cycle intervals. When the cyclic switching-on and off stops, judgement is performed in that the breaking of either of the rollers occurs.

Title: Digital telephone set
Inventor: HIBINO OSAMU
IPC: H04M1/253
Filed: 1986-09-19
Abstract: PURPOSE:To hear only a side tone from a central office and to eliminate unnatural feeling in calling by stopping a side tone arising in the interior of a digital telephone set at the time of originating through the central office. CONSTITUTION:A central office call detection means 20 detects that a call is made through the central office, judging from the operation of a subscriber, operates a cutting means 19, cuts the connection between an attenuator circuit 12 and an adder circuit 11, and stops the side tone arising in the interior of the digital telephone set. When said telephone set is connected to the central office, the side tone caused by a hybrid circuit in the central office returns to the digital telephone set. Therefore the subscriber can hear the side tone. Thus the side tone in the interiror of the digital telephone set never overlaps with the side tone caused by the hybrid circuit in the central office, whereby the side tone is not distorted and the natural feeling in a call is maintained.

IPC: H01L31/10
Filed: 1982-12-22
Abstract: PURPOSE:To increase the photo output at the time of a constant illuminance and thus prevent the deterioration of sensitivity on the side of a low illuminance by reducing the base concentration in the periphery of the emitter of an N-P-N transisor and reducing the capacitance between the base and the emitter. CONSTITUTION:Two kinds of diffusions of P type diffusions 3 and 4 and N type diffusions 2, 5, and 6 are formed on the surface of an N type semiconductor substrate 1, and form a P-N-P transistor Q2 having an emitter 4, a base 5, and a collector 3 and the N-P-N transistor Q1 having a collector 1, a base 3, and an emitter 6. The symbol Cje is the junction capacitor between the base and the emitter 4. And, the Cje can be more decreased than in a conventional example, even when the area of the emitter 6 of the N-P-N transistor Q1 is made constant by decreasing the P type diffusion concentration of the region 3 more than that of the region 4. Besides, the concentration of the emitter 4 of the P-N-P can be increased, and accordingly the emitter injection efficiency increases.

Title: Microwave electric-discharge light source device
Inventor: OONUKI KAZUSHI
IPC: H01J65/04
Filed: 1982-12-21
Abstract: PURPOSE:To reduce the leakage of microwaves by driving the microwave- producing source of a microwave electric-discharge light source device having a single-mode cavity resonance with a decreased electric input for a given time from the time of starting of the device. CONSTITUTION:Microwave radiated by a magnetron 1 is introduced into a rotationally symmetrical cavity through a waveguide 4 to develop a magnetic field, by which an electric discharge lamp 6 is excited and caused to emit light. Capacitors C3 and C4 are connected to or disconnected from capacitors C1 and C2 by controlling contacts TS1 and TS2 by providing a timer TM in a circuit for driving the magnetron 1. Therefore input which is to be fed to the magnetron 1 can be reduced by leaving the contacts TS1 and TS2 open for a given time in starting the device. As a result, the leakage of microwave energy caused due to the mismatching of the impedance of the cavity 4 before burning is reduced, thereby enabling the safety of the device to be increased.
