Title: Subscriber's line radio concentration system for time-division exchange
Inventor: KAMATA KOZO
IPC: H04W4/00
Filed: 1985-12-24
Abstract: PURPOSE:To reduce the amounts of hardwares and softwares necessary for connecting a terminal to a private branch digital exchange by allocating prescribed time slots of the exchange to respective ones of the terminals to be concentrated, and redisposing the terminals to the time slots after the concentration and accommodating them. CONSTITUTION:A 'dial-able'-signal transfer is written in the field #614 in the individual signal time slot of a link down frame. Accordingly, a radio telephone terminal 614 transmits an audible sound. A caller, after hearing this sound, dials the telephone number of the opposite. The dialed number is temporarily stored in the terminal 614. And at the time when the last digit is dialed, the number is collectively transmitted by a link-up individual time slot '4'. The controlling part 77 of an odd-number time-slot-group radio equipment 7, when receiving said dial number via a receiver circuit 76, sequentially transmits it to the field #614 of the time slot of the PCM primary-group frame of exchange highway.

Title: Magnetron for microwave oven
Inventor: KAWAGUCHI TOSHIO
IPC: H01J23/54
Filed: 1990-10-31
Abstract: PURPOSE:To suppress a multipactoring discharge and improve reliability by forming a metallic cylinder for a high frequency choke coil of the innermost side into a taper-like or funnel-shaped one relative to a tube axis. CONSTITUTION:A metallic cylinder 32 for a small diametral first high frequency choke coil on the innermost side is arranged on the same axis as a metallic cylinder 31 for a second high frequency choke coil and a metallic container 19, inside the cylinder 31. In this case, the cylinder 32 is formed taper-like relative to a tube axis so that is length is shorter than that of the cylinder 31 and its inner diameter becomes gradually small in the direction of a spiral filament cathode 15, an it is not in parallel with an antenna lead 25. Consequently, electrons move in the axial direction, but since the cylinder 32 is taper-like and its inner diameter varies, microwave field distribution is also changed. Oscillation of electron thus can not stably be synchronized with a microwave frequency. As a result, the generation and continuance of a multipactoring discharge can be prevented from occurring beforehand.

Title: Garbage treating device
Inventor: SEKIGUCHI TAKASHI
IPC: B01F7/04
Filed: 1996-11-01
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of sounds, to decrease the torque for agitation, to execute the agitation with the stable torque and to enhance the efficiency at the time of residue taking out by forming the front ends of agitating members to an L shape and specifying the angles formed by the respective sides of the L-shaped front end shapes to a specific value or above. SOLUTION: The garbage charged from a charging port 10a is admitted into a base material 1 by agitating blades 9. At this time, the L-shaped parts are bent by >=90 deg. while the clearance H between a treating vessel 2 and the agitating blades 9 is minimized, by which an inclination is formed in the clearance from the treating vessel 2. As a result, the clearance area with the wall surface of the treating vessel 2 is increased and the friction resistance lowers even if the garbage is held therein. If the friction resistance is low, there is an effect of decreasing the sounds by friction and the stresses acting on the tips of a reduction gear 6 are relived. Then, the generation of the sounds is prevented and the agitating torque is decreased, by which the agitation by the stable torque is made possible.

Abstract: PURPOSE:To provide a voice emitting device which can emit natural voices of good quality. CONSTITUTION:Word phonemic piece data corresponding to the form element (word) processed by a form element analyzing device 4 is decided, and each piece of the data is divided into a steady part and a transient part. The transient part corresponding to the connection part of each word phonemic piece data is substituted with transient part phonemic piece data for connection so that the word phonemic piece data is connected bit by bit, This lessens the connection part to lead to lessening of distortion caused by connection, and it is possible to produce synthetic sounds of good quality. Because the duration of each phoneme can be controlled individually for steady part and transient part, so that it is possible to widen the expansion and contraction of the steady part and narrow those of the transient part in the same manner as real voice, and emission of natural voice can be achieved.

Title: Monitoring apparatus of insulation of illuminator for road
Inventor: MISHIMA NORIHISA
IPC: G01R27/02
Filed: 1988-11-18
Abstract: PURPOSE:To facilitate an operation for maintenance and check by injecting a low-frequency zero-phase voltage from a neutral point on the secondary side of a receiving transformer by a zero-phase voltage injecting means and by injecting a comparison signal into a branch line. CONSTITUTION:A low-frequency zero-phase current flowing through a feeder 3 is detected by a zero-phase current detector 12 of an injection frequency extracting means 12. A band-pass filter 12b extracts an injection frequency component contained in the low-frequency zero-phase current detected by the zero-phase current detector 12a and gives it to an amplifier 12c. The amplifier 12c amplifies the injection frequency component extracted by the band-pass filter 12b and gives it to a central processing unit 8 through a switching element 10 of a monitoring station 1. The central processing unit 8 receives the injection frequency component from the detector 12 as an input through the switching element 10 and calculates an insulation resistance from this injection frequency component. Then, the central processing unit 8 compares a calculated value of this insulation resistance with a reference value and determines deterioration of insulation. As the result, the deterioration of insulation of a collective system of the feeder 3, a branch line 4 and an illuminator 5 for a road can be monitored by the central processing unit 8.
