Title: Dubbing device
Inventor: WAKAYA SHIGEKI
IPC: G11B15/02
Filed: 1985-01-18
Abstract: PURPOSE:To decide whether dubbing operation is completed or not by providing a master tape recorder with a playback signal detecting circuit and the 1st timer circuit, and a slave tape recorder with a tape end detecting circuit, the 2nd timer circuit, a decision circuit, and a display means. CONSTITUTION:The master tape recorder M and slave tape recorder S run a loaded tape and signals are reproduced by magnetic heads 1A-1D and recorded by magnetic heads 9A-9D. A timer circuit 4 sends out an output signal when a tape end is almost reached and a specific time is elapsed after no playback signal is detected. When the tape end is detected in the recorder S, the output signal is inputted to a payoff side motor circuit 8S and a timer circuit 11A. The output signal of the circuit 4 is passed through a monostable multivibrator 13 to send a trigger signal to an FF12, and the circuit 11a sends a rest signal to the FF12. When dubbing operation is incomplete, a light emitting diode 14 is turned on with the output off the FF12 and a take-up inhibiting signal is supplied to the circuit 8S.

Title: Magnetic head
Inventor: ISHIDA BUNJI
IPC: G11B5/127
Filed: 1988-01-14
Abstract: PURPOSE:To reduce noise of a reproduced picture at joints of consecutive recording by fixing an erasure part of an erasure magnetic head to the same angle in the scanning direction of a rotary drum head. CONSTITUTION:The erasure part 1 of the erasure magnetic head is fixed to the same angle as the direction of video information 3, that is, the scanning direction of the rotary drum head. Thus, the recording position cannot be correctly erased when compared with the flying erase system, but noise is reduced in comparison with the full erasure system. Moreover, the erasure part of the erasure magnetic head is fixed to the same angle as the scanning direction of the rotary drum head, but much noise is reduced than that of the full erasure system without adopting the same angle and the noise is reduced by only somewhat tilting from the perpendicular state. Thus, the noise of the reproduced picture at the joints is reduced.

Title: D/a converter
Inventor: ODA TOSHIAKI
IPC: H03M1/66
Filed: 1989-01-12
Abstract: PURPOSE:To obtain a D/A converter with high precision by using a circuit dead to the parasitic capacity of a switch. CONSTITUTION:An oscillator 1 outputs a certain frequency f0, and a reference voltage generator 5 outputs a reference voltage VREF. The frequency f0 is inputted to a variable frequency divider 2, and this divider 2 divides the frequency. The frequency division number at this time is changed by a digital input signal DIN. Since the input of a switched capacitor integrator 6 is the DC reference voltage VREF, the output of this integrator 6 is proportional to a digital input signal (n), and it is operated as a D/A converter. Since this circuit is dead to the parasitic capacity of the switch, the influence of the parasitic capacity is eliminated, and D/A conversion is performed with high precision.

Title: Apparatus for cooling and rapidly freezing specimen of biological substance received in container
Inventor: URURITSUHI TSUEE KUNOPUFU
IPC: G01N1/28
Filed: 1988-01-18
Abstract: Apparatus for cooling and deep freezing samples of biological material. The cooling zone, containing the closed plastic vessels with the samples, is enclosed between two parallel, plate-like layered cooling elements. The latter are made of at least two cooling layers containing blocks of Peltier elements, alternating with plates of a heat-conducting metal, preferably aluminium. The disposition with several layers of Peltier elements increases the temperature difference between the inner space and environment. The innermost layer of the cooling elements is a metal plate as well; the outermost layer is a metal plate with means for external cooling, such as channels for circulating water or cooling ribs. The cooling zone is either a metal block with cavities to receive the sample vessels or simply the free space between the two innermost plates of the cooling elements, into which the vessels can be inserted. In one special design the metal block is an exchangeable module or cassette to be inserted into the cooling space. All parts, except the plates cooled externally, are thermally insulated; the cooling space is sealed against humidity by an insulated lid. The apparatus is controlled by a programmable electronic unit, by which a temperature program for the freezing process can be followed. The signals are given by temperature sensors in the cooling zone. In a preferred design, the freezing apparatus, the electronic control unit and the power supply are combined together in portable housing box.
