Title: Improvements in apparatus for discharging foam
IPC: B01F5/04
Filed: 1945-04-20
Abstract: 599,821. Making foam. NATIONAL FOAM SYSTEM, Inc. April 20, 1945, No. 9992. Convention date, Oct. 25, 1944. [Class 47 (ii)] A stream of foam which has been generated by a jet device is rendered non-turbulent before discharge by passage through a conduit which first reduces its velocity until turbulence is removed, and then increases it just before final discharge. As shown, the jet device 10 clischarges foam in a turbulent condition into a conduit comprising a section 27, an enlarged section 28 in which the stream is slowed down to remove turbulence, and a short reduced section 29 which restores the velocity of the stream to its original value just before the stream is discharged from the orifice 26. The enlarged section is fitted with a conical screen 30 to afford a resistance to the foam stream and with longitudinal vanes 31 which subdivide the stream to assist in removing turbulence. Specifications 427,536, 526,145, 541,318 and 578,447 are referred to.

Title: Field effect transistor amplifier
Inventor: ITOU HIROSHI
IPC: H03F1/34
Filed: 1983-01-10
Abstract: PURPOSE:To prevent the generation of a noise by setting the potential of a gate while providing negative feedback through a resistance which connects an output and an input stage directly, and matching input impedance. CONSTITUTION:A terminal 42 in a figure is a voltage terminal for adjusting the resistance value of an FET38. This utilizes the variation in the drain-source resistance (FET resistance) of the FET38 with the gate-bias voltage, and consequently the feedback resistance value is controlled by the gate voltage through the FET resistance to control the input impedance, output impedance, gain, and band. A noise generated by the feedback resistance is therefore reduced by the negative feedback to reduce the effective contribution of the noise, and the gate bias is set to realize the input impedance matching. In general, the noise current generated by the FET is relatively large, so the noise is reduced when a resistance is used as a load.

Title: Control method for bus usufructuary right of direct memory access channel
Inventor: YAMAOKA HIROMASA
IPC: G06F13/28
Filed: 1980-01-11
Abstract: PURPOSE:To make it possible to use the bus of the CPU even if the bus occupied time increases, by sending a bus using request from the DMA channel only when the using request and approval are not generated in the bus using request line and the bus using approval line. CONSTITUTION:The DMA controller 13 which has received a DMA transfer request signal from the input/output apparatus sends out a bus using request signal 103 to the priority control circuit 31. In this case, if a bus using request signal 109 is sent out to the CPU from other DMA channel, the gate 302 is inhibited, and the FF303 is not triggered. Also, in case when a bus using approval signal 110 is sent out from the CPU, as well, the FF303 is not triggered, and the signal 109 is not sent out to the CPU from this DMA channel. When the DMA transfer of other channel is finished and the signal 110 is released, the FF303 is triggered. Accordingly, even if the bus occupied time of the DMA channel increases due to failure of the input/output apparatus, the CPU does not stop but is able to execute the processing of the failure.

Title: Exhaust fan control device of rice washing and cooking machine
Inventor: TOKUNAGA NAOKI
IPC: A47J27/14
Filed: 1995-01-09
Abstract: PURPOSE: To prevent an electrical equipment chamber from being filled with vapor just after the end of rice cooking by controlling the drive of an exhaust fan of the electrical equipment chamber during the period of a fixed time after the end of rice cooking in a rice cooking pot. CONSTITUTION: While a rice cooking pot after rice is washed and cooked is removed from a rice washing vessel 5 and the lower position of a hopper case 2 or the like, an exhaust fan is forced to continue rotation by turning on the switch of a fan motor to discharge air in an electrical equipment chamber 4 from an opening 37, so that moisture can be kept from staying in the electrical equipment chamber 4. That is, in a hopper case 2 surrounding a rice hopper 1, the exhaust fan 7 is driven by the motor from the start of washing rice in the rice washing vessel 5, and the drive of the exhaust fan is continued during a fixed time also after the end of rice cooking, to say nothing of the period extending from rice washing to rice cooking.  During the period of time until the rice cooking pot is removed from the lower side of the rice washing vessel 5, even if the hopper case 2 receives a large quantity of vapor generated, the quantity of vapor and hot air staying in the electric equipment chamber 4 can be reduced so as to heighten a moistureproof effect.

Title: Operation mechanism of cassette tape deck
Inventor: NAGATANI HIDEJI
IPC: G11B33/02
Filed: 1984-01-09
Abstract: PURPOSE:To miaturize a cassette tape deck by providing a supporting member that rocks in interlocking with a cassette holder and a working piece engaged with the rocking end and rocks interlocking with the supporting member. CONSTITUTION:A style strip 18A that supports a cassette half at a fixed position to a tape driving mechanism is supported to allow free rocking, and energized counterclockwise by a spring 19A, and rocked in interlocking with the cassette holder 7A. When the cassette half 6 is loaded, the working piece 22A that locks in interlocking with the style strip 18A saves to a position that does not hinder loading, and after loading, inserts the claw 22a into a detection hole of the half 6 to operate a leaf switch for detecting half 20A and detects information relating to the half. Accordingly, it becomes unnecessary to provide a mechanism to liberate the working piece to prevent from being catched when the cassette half 6 is loaded in the fixed position, and the device can be miniaturized with simple mechanism.

Title: Radio receiver
Inventor: HORIIKE YOSHIO
IPC: H03J7/28
Filed: 1985-01-09
Abstract: PURPOSE:To facilitate a tuning operation even with an on-vehicle radio receiver, etc. by stopping assuredly an automatic tuning action even under the working conditions where the field intensity has a big change. CONSTITUTION:The output (c) of a bistable multivibrator 11 is kept at a high level although the output (a) of a detection circuit 10 is set at a low level owing to the temporary discontinuation of radio waves when a car enters a tunnel, etc. Then the output (c) is applied to a microcomputer 9. The reception frequency of the computer 9 is stopped for 5sec, for example, after the output (c) of the vabrator 11 is set at a high level. This reception frequency starts its variation again after 5sec. Thus the lock-out output (h) of a PLL circuit 8 is set at a high level. While the output (c) of the vibrator 11 is reset to a low level. This output (c) is kept at a low level until the next channel is received. Thus an automatic tuning action is attained.
