Title: Scramble system of television signal
Inventor: KOMORI TOSHIO
IPC: H04N7/167
Filed: 1980-02-04
Abstract: PURPOSE:To realize a charged TV broadcast in a simple constitution, by giving a scramble process to the signal level with an AC signal obtained from an AC power source for transmission and then giving a scramble process to the received signal with an AC signal synchronizing with the precedent AC signal. CONSTITUTION:The composite video signal CV1 received a certain pedestal level is supplied to the signal switch circuit 3 along with the signal CV2 which is shifted via the level shift circuit 2, and then turned into the signal having the signals CV1 and CV2 arranged alternately by the rectangular wave SWS which is obtained by giving a waveform shaping to the AC signal ACS of an AC power source. The above-mentioned signal received through the antenna 7 is supplied to the electronic control attenuator 11 and then receives such amount of attenuation by which the peak level in the period of high level of the control signal SWR obtained by giving a waveform shaping to the AC signal ACR synchronizing with the signal ACS of the transmission side becomes in agreement with the peak level in the period of low level. Thus the signal is supplied to the picture receiver 12 in the form of the normal TV signal.

Abstract: PURPOSE:To equalize a set traveling speed to an actual traveling speed and to easily vary the set traveling speed without any complicate adjustment by providing a traveling speed setting means, a detecting and counting means, and a speed voltage generating circuit. CONSTITUTION:When a counting end signal (c) is inputted to a control circuit 34, the circuit 34 sends out a control signal to a clock generating circuit 35 to stop the generation of a clock signal (d). The 2nd counting circuit 36, on the other hand, sends out a control signal and its counting result is held. Consequently, the state wherein a constant counting result value is sent from the circuit 36 to a D/A converting circuit 37 is entered and the circuit 37 outputs a constant speed voltage signal (e) to a driving circuit 13. Consequently, a payoff reel motor 19 controlled by a circuit 13 rotates at a constant rotating speed. Consequently, the magnetic tape 1 is held at the set traveling speed set by the traveling speed setting means 33. Further, the set value signal from this means 33 is varied and the generation timing of said signal (c) is varied to vary the traveling speed of the magnetic tape 1.

Title: Nonlinear emphasizing circuit
Inventor: YASUMURA HIROTO
IPC: H03G9/02
Filed: 1983-01-28
Abstract: PURPOSE:To obtain the desired nonlinear emphasis characteristics even with a small input signal by supplying the high band component of the input signal to an HPF after amplifying it and then feeding back negatively the high band component to the front stage through a circuit consisting of an HPF and a limiter circuit to obtain an output. CONSTITUTION:When a signal of a small amplitude is supplied to an input terminal 11, both diodes D11 and D12 have no conduction. Then a negative feedback signal VN to be applied to an amplifier 14 is set at 0, and the output signal V1 of an HPF13 is directly amplified and turned into an output V0. When a signal of a large amplitude is supplied to the terminal 11, the diodes D11 and D12 conduct. Then the output V0 is fed negatively to the amplifier 14 via an HPF16 and an amplifier 17. Therefore only the difference signal between signals V1 and VN is amplified for the output V0. In this connection, a circuit shown in the diagram has the same characteristics as a conventional circuit. Hereby the gains of amplifiers 14 and 17 are set at n1 and n2 with the gain of the HPF16 set at n3 respectively. Thus the output V2 of the amplifier 17 is set at n1.n2.n3.V1, and therefore the level of the input signal can be reduced down to 1/n1n2n3 of the conventional level to obtain the desired characteristics.

Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To provide a method and equipment for manufacturing resin- encapsulated semiconductor devices, with which dam bar resin is securely cut off making it hard to be broken, by cutting off the dam bar resin with cylindrical resin cutting punches, each of which is guided by a punch guide. SOLUTION: Dam bar resin is cut off by cylindrical cutting punches 12, each of which is held on a pedestal and is guided by a punch guide 13. Because of the cylindrical structure of the cutting punches 12, integral molding to form a pectinate structure is not necessary, and it is possible to adopt a structure of just holding the cylindrical members upright on a pedestal. In addition, the punch guide 13 for guiding each cylindrical cutting punches 12 is of a structure with a simply pierced round bore. The dam bar resin is cut off uniformly, making it hard to be broken in subsequent processes. The cut shape of the dam bar resin is also kept uniform, because the cylindrical cutting punches 12 are abraded uniformly keeping themselves cylindrical.

IPC: A61C5/02
Filed: 1989-01-25
Abstract: PURPOSE: To make a file act as a path finder to proceed in a root cap without harming the tip end part, by providing at least two files and equipping a safety end part with length different from that of the other file on one tip end part and the other file on the other tip end part. CONSTITUTION: Files 10 and 12 are different mainly in the finishing method of the cut edge. The cut edge of the file 10 is spiral and, on the other hand, the 'stepwise' or 'telescopic' cut edge of the file 12 is in a gentle angle against the file axis line. Files 10 and 12 have shank parts 14 and taper parts 16. The length of the 'safety end parts' 24 of the tip end file 30 is gradually changed to prevent fragments and fillers to be pushed out from the top end. Since a paper tip end stop with proper retaining power and resistance is generated, it acts as a path finder to proceed in a root cap without harming the tip end part.

A joining/ branching part 13 joins the respective optical signals outputted from the front stage shutter part 12, turns them to a wavelength multiplexed optical signal and branches the joined optical signal to N pieces of outgoing lines. A rear stage shutter part 14 extracts the optical signals of the prescribed wavelengths from the N pieces of respective branched and inputted optical signals, inputs those signals to an output part provided with the N pieces of fibers, guides the optical signals of the prescribed wavelengths through the respective fibers to outgoing lines #1-#N and performs the spatial switching of optical signals.

Filed: 1981-02-03
Abstract: PURPOSE:To eliminate the variance of the initial spring force and to obtain large increase ratio by obtaining the energizing spring force by a break spring and an adjusting spring which resists to it. CONSTITUTION:The pressure of a sealed liquid chamber C controlled by an intertia valve 19 is transmitted to a spring seat 18 via a see-saw link 27, said spring seat 18 pressing a break spring 16 which in turn pushes a control piston 6 of a proportioning valve via a spring guide 15 to which an adjusting spring 17 is also engaged thereby applying the resultant force of the both springs to the control piston 6. Thus, only the differential force between the break spring force and the adjusting spring force will be applied to the piston even when the initial load of the break spring 16 is set large, enabling good break value over the empty load to the maximum load.
