Title: Inverter
Inventor: SHIMIZU KEIICHI
IPC: H02M7/537
Filed: 1988-09-13
Abstract: PURPOSE:To flatten the characteristics of a secondary voltage without a load in a one-transister type parallel resonating inverter by decreasing a loop gain when an operating frequency undergoes negative feedback control in order to make the peak voltage of a switching element constant. CONSTITUTION:A frequency control circuit 7 has the following part: an error amplifying circuit 72 which compares the output of a reference voltage source 71 with the output of a peak voltage detecting circuit 6, amplifies the error voltage at a specified gain and outputs the result; a variable resistor 73 which adjusts the gain of the circuit 72; and a voltage-controlled type oscillator 74 which oscillates a frequency in response to the output of the circuit 72. The base of a Tr 3 is driven with the frequency in response to a collector voltage. The variable resistor 73 is adjusted, and the gain of the amplifier 72 is set at a low value. In this way, the load voltage can be flattened when the inverter has no load.

Filed: 1990-08-30
Abstract: PURPOSE:To improve S/N of the analog output based on a waveform shaped output by separating the power system of a waveform shaping part from that of a preceding stage circuit to prevent an influence of the noise in the power system of the preceding stage circuit upon the waveform shaped output. CONSTITUTION:In an oversampling type DA converter, the power system of the waveform shaping part of a waveform shaping circuit is separated from that of the circuit preceding the waveform shaping part. That is, two power lines of a NAND gate 22 are separated from a power line VDD1 of a first power system and GND1 and are connected to a power line VDD2 of a second power system and GND2. Consequently, the potential variance of power lines has not an influence upon the power system of the waveform shaping part though occurring in the preceding stage circuit, and the waveform shaped output of less noise is obtained. Thus, S/N of the analog output is improved.

Abstract: PURPOSE:To separate a pattern without falling down a mold by placing the mold which is molded on molding board, on rollers so as to be freely changeable in optional direction, binding a rope with an arm of a molding flask and gradually hanging up with a crane. CONSTITUTION:Many rollers 8 freely changeable in directions are arranged in the same plane and the mold molded on the molding board is placed on the rollers 8 in this posture and the rope bound to the arm of the molding flask and gradually hung up with the crane. Then, when there is some shifting in centroid points between a hanging up action line of the crane rope and the mold, the molding board is shifted on the roller so as to be freely changed to the direction, and automatically becomes the matching condition. In this condition, at the time of winding up the rope, the mold is separated and raised, and the molding board and the pattern remain on the roller. By this method, without turning over the integral of the molding board, pattern and mold, and without breaking the mold, the pattern can be separated from the mold with only one worker.

Title: Mode discriminator
Inventor: SATO KOICHI
IPC: H04N5/93
Filed: 1988-09-13
Abstract: PURPOSE:To make a discriminator smaller by discriminating a mode with both of the level of a regenerative RF signal and the level of a carrier included in it. CONSTITUTION:Central frequencies of a band pass filter 21 are set, for example, at a first carrier (or a second carrier). As a result, a first comparator 23 outputs, for example, logic 1 when the first carrier is reproduced, and it outputs logic 0 when the second carrier is reproduced respectively. On the other hand, a second comparator 14 outputs, for example, the logic 1 whenever either carrier is reproduced. As the result, by operating the output of the two comparators 23 and 14, for example, by means of a logical circuit consisting of an AND gate 25, the carrier (mode) can be correctly discriminated. Thus, a single comparator is sufficient, and the discriminator can be made smaller.
