Abstract: PURPOSE: To improve operation of a device, by supplying power to tuner and amplifier of a radio receiver via the operation switch of a tape deck.  
     CONSTITUTION: The power supply fed from a battery 3 to a deck 1 is supplied to regenerative amplifiers 7, 8 and emitter follower circuits 9, 10 via a playback side contact 6a of a switch 6 and to a control circuit 5 of the deck via an operation side contact 4a of a switch 4, and further fed to a terminal 1c to be fed to the amplifier A of a radio receiver 2 for the playback of tape. When the switch 6 is selected to a recording side contact 6b and recording/playback switches 17, 18 to recording side R respectively, the power supply is fed to recording circuits 13, 14 of the deck 1, and recording is made by monitoring the output of a radio fed to the tuner T and amplifier A of the radio receiver 2. When the switch 4 is switched to the stop side 4b, the radio receiver only is operated to make listenable the radio receiver.

Abstract: PURPOSE:To prevent the deformation and the blow hole development of a core and to obtain a precise cast product by filling up molten metal into a cavity with low jetting pressure, thereafter, increasing the jetting pressure and exhaust ing the remained gas from the cavity. CONSTITUTION:Molten aluminum 55 is jetted with comparatively low pressure from gates 46a, 46b for jetting arranged at the end part and the center part of the cavity 45 of a fixed die 41. When the molten aluminum 55 spreads almost in the whole range of the cavity 45, the jetting pressure is increased so as to exhaust the remained gas in the cavity 45 from gap 30 between the fixed die 41 and the synthetic resin core 10 to outside. The load applied to the synthetic resin core 10 is restrained to load by jetting the molten aluminum 55 with the comparatively low pressure to prevent the deformation, and the remained gas is exhausted from the cavity 45 by increasing the jetting pressure to prevent the development of the blow hole, and the casting having high precision of the shape can be obtd.

Filed: 1985-08-02
Abstract: PURPOSE:To obtain a duct inexpensive in cost and having a highly airtight function by covering the entire part of the outer surface of a duct structure with a seal layer made of a plastic foaming member. CONSTITUTION:The duct 1 has a large number of exposed portions having a possibility of leaking such as a joined portion F of duct units 2 and 2 and a seam S formed by side seaming and the like. In order to prevent the leakage from the junction F and seam S, the entire part of the outer surface of the duct 1 is completely covered with a seal layer made of an independently foaming plastic foaming material 8. More specifically, while admixing urethane with a foaming agent, the mixture is sprayed onto and foamed on the outer surface of the duct 1 to form a seal layer 9. At the time of foaming, the internal temperature of the foaming layer rises to 80 to 100 deg.C, and the foaming pressure reaches 20 to 50kg/m<2>. For this reason, at the inner surface side of the foaming layer in contact with the outer surface of the duct 1 air bubbles are crushed to form a skin layer 9a having a thickness of several mm and rich in the adhesive proparty.

Abstract: PURPOSE:To obtain an objective speed of a rotor without control by comparing in phase the frequency output of an oscillator becoming a reference with that of a device to be controlled and obtaining a speed signal corresponding to the displacement from the objective frequency, thereby performing the speed control. CONSTITUTION:The pulse of a frequency proportional to the rotation of a rotor 1 is amplified by an amplifier 4, and is converted by a converter 5 into a sawtooth wave b. On the other hand, the sawtooth wave b is sampled and held by the first sample-holding circuit SH1 with a sampling pulse P2 obtained by adding the sampling pulse P1 from a reference signal generator 6 such as a crystal oscillator or the like to the first delay circuit D1, and is further sampled and held by the second sample-holding circuit SH2 with a sampling pulse P1. The outputs from the circuits SH1, SH2 are applied to a differential amplifier 7, which in turn produces a difference signal. The output from an FF1 is applied through the third delay circuit D3 and the pulse delayed via the second delay circuit D2 are then applied to an AND gate G, allowing the third sample-holding circuit SH3 to sample and hold the output of the amplifier 7. Subsequently, the phase error signal of the circuit SH1 and the speed error signal of the circuit SH2 are added by an adder 8, thereby controlling the rotor 1.

Filed: 1982-09-29
Abstract: PURPOSE:To eliminate the need to use adhesives, to improve reliability, and to facilitate manufacture by forming a TiO2 film and an SiO2 film on a substrate alternately and then forming an Si3N4 film over the outermost film. CONSTITUTION:The TiO2 film 2 and SiO2 film 3 are laminated on the substrate alternately. Further, the Si3N4 film 6 is vapor-deposited on the outermost film 3 on an air side. The refractive index of the film 2 is 2.3 and that of the film 3 is 1.46, so the film 6 having an intermediate refractive index between those of film 2 & 3 e.g. 1.8-1.9 is formed. Consequently, the obtained optical fiber is almost as good as or better than an optical filter having a glass substrate adhered to the outermost layer. Thus, no glass substrate is adhered, so the reliability is improved and the filter is formed by a method similar to the formation of a dielectric multi-layered film, thereby facilitating the manufacture.
