Title: High-speed light signal generator
Inventor: MITA AKIRA
IPC: H04B10/00
Filed: 1980-01-31
Abstract: PURPOSE:To improve the reliability by obtaining a bulk effect element by forming a gallium-aluminum-arsenic layer of high resistance and thin gallium-arsenic crystal operating layer on a gallium-arsenic crystal substrate in photoconductive structure. CONSTITUTION:While semiconductor laser 11 having an output at the side of a wavelength longer than one mum is used as a light source, output light 12 is focused by focusing means 13 and then incident to bulk effect element 14, constituted in a photoconductive path shape, from its flank. Bulk effect element 14, made of Ga-As single crystal 15 as a substrate, has operating layer 17 made of a Ga-As layer via clad layer 16 made of a Ga-Al-As layer of low refractive index grown on the substrate, in addition to cathode and anode electrodes 18' and 18'' for bias voltage application at both ends and trigger electrode 18 for inputting external signals near the cathode, thereby permitting this element to provide planar operation. The laser light is modulated and then its transmitted light 19 is converted via lens 20 into a parallel luminous flux, which can be led out by polarizer 21.

Title: Hot air device
Inventor: HASHIMOTO KENJI
IPC: F02G1/044
Filed: 1982-01-25
Abstract: PURPOSE:To effectively carry out the production of warm air in a device in which a fan is coupled to the crank mechanism of a hot gas reciprocating engine, by arranging the device such that the rotation of the fan causes air stream to be discharged through a heat source. CONSTITUTION:In case of using a hot air device in a pot type oil burner, the heating part 31 of a hot gas reciprocating engine 5 is insetered in a pot 4 within a combustion cylinder 2. With the use of the closed cycle motion of operating gas including isothermal compression due to temperature differential between the heating part 31 and the cooling part 32 of the engine 5, constant-volume heating, isothermal expansion and constant-volume cooling, the hot gas reciprocating engine 5 reciprocates a displacer 33 and a piton 34 with a phase differential therebetween. Such reciprocating motion is converted into rotational  motion by a crank mechanism 38, and therefore, a combustion air supplying fan  7 in an air supply cylinder 23, attached to one end of a crank shaft 6 and a  discharge air fan 8 in an exhaust cylinder 22, attached to the other end of the crank shaft 6, are rotated, respectively.

Title: Rice cooker
Inventor: MIYAKE KAZUYA
IPC: A47J27/00
Filed: 1993-01-26
Abstract: PURPOSE:To execute comparatively satisfactory rice cooking even in the case of a state that a sensor for detecting a rice cooking temperature detects a temp. a little higher than that of an original detection. CONSTITUTION:As soon as rice cooking is started, time counting of a t1 time is started. When a pot sensor detects a temp. of >=120 deg.C, a rice cooking heater is turned off. Subsequently, whether the time t1 has passed more than 10 minutes or not is checked, and when more than 10 minutes, it is decided that rice cooking is performed normally, and steaming is executed for 15 minutes. On the other hand, when the time t1 is less than 10 minutes, time counting of a t2 time is started continuously. Next, when the temp. of >=106 deg.C is held before the elapsed time t2 reaches 10 minutes, it is deemed that rice cooking is normally performed and steaming is executed for 5 minutes. However, if the temperature falls from 106 deg.C during that time, it is decided that rice cooking is abnormally performed and the rice cooking operation is continued by setting a heating rate of the rice cooking heater to 70%W, and when the temperature reaches >=122 deg.C, the rice cooking heater is turned off and steaming is executed for 10 minutes.

Title: Light-emitting diode
Inventor: MATSUBARA HIROSHI
IPC: H01L33/30
Filed: 1979-02-01
Abstract: PURPOSE: To improve the coupling efficiency for LED and fiber by providing a current concentrating mechanisms at the upper and lower sides of a light-emitting layer, in a light-emitting diode suitably used in optical fiber communication.  
     CONSTITUTION: The LED consists of metal electrode layer 1, n-type GaAs substrate 2, n-type GaAlAs layer 3, p-type GaAs layer 4, p-type GaAlAs layer 5, n-type GaAlAs layer 6, p-type GaAlAs layer 7, and metal electrode layer 9 having opening 8. P-type GaAs layer 10 is buried between n-type GaAs substrate 2 and n-type GaAlAs layer 3, excluding the part immediately below opening 8. When voltage is impressed on a LED of this structure, reverse biasing takes place not only between layer 5 and layer 6 but also between layer 10 and layer 2. As a result, with its path choked in circular form, current flows into layer 5. When it passes through layer 4, it slightly expands, but it is choked again and flows into substrate 2. Consequently, most of the current flowing to the LED chip concentrates immediately below opening 8 flowing toward substrate 2, so that the coupling efficiency is improved.

Title: Volumetric flowmeter
Inventor: KOSEKI MINORU
IPC: G01F3/10
Filed: 1989-01-20
Abstract: PURPOSE:To measure a flow rate more finely by providing a couple of rotors, annular magnets embedded in the rotors, a detecting means, an arithmetic means, etc. CONSTITUTION:Fluid flows in a metering chamber from an intake passage to rotate the couple of rotors 4 and 5 at a rotating speed corresponding to its flow rate, and then flows out to an outlet passage. The rotation of the rotor 4 is detected by a magnetoresistance element 19 as a detecting means which is incorporated in a lid. Namely, the element 19 is provided nearby the magnet 12 formed in the rotor 4 by insertion and while the rotor 4 makes one rotation, the pulses as many as magnetic poles magnetized in the magnet 12 are outputted. Thus, the pulses outputted by the element 19 become irregular in pulse intervals as the rotors 4 and 5 rotate irregularly and are supplied to a control circuit 22. A control circuit 22 as the arithmetic means which inputs the signal calculates the flow rate, flow velocity value, and instantaneous flow rate, which are displayed 25, 28, and 29. Then the control circuit 22 measures the flow rate more finely because the element 19 outputs more signals per rotation of the rotor 4 than before.

IPC: H01L21/762
Filed: 1980-02-01
Abstract: PURPOSE:To obtain a device of higher integration and improved properties, by forming a field oxidized film on a substrate surface without employing the selective oxidation method, forming selectively an inversion preventing layer to the said portion and preventing oozing to the device region. CONSTITUTION:An SiO2 12, a polycrystalline Si 13 are stacked on a P type Si substrate 11, and a resist mask 14 is coated to form P<+> layer 15 by B ion implantation. After removal of the mask 14 and the evaporation of Al 16, the layer 13 is removed by a reactive ion etching. Then with the Al 16 as a mask, the SiO2 12 is etched by a reactive ion etching for an opening and the Al 16 is exfoliated. Because of the reactive ion etching, side etching on the oxidized film 12 is virtually zero. Moreover, as no oozing by ion implantation takes place on the P<+> layer, a minute  device forming region as designed can be obtained. Therefore, by employing the  conventional method to form a MOSFET, a device of higher integration and improved properties can be obtained.
