Title: Photoelectric conversion element
Inventor: UCHIDA YOKO
IPC: H01L31/04
Filed: 1992-06-05
Abstract: PURPOSE:To enlarge the optical path length of a light absorption layer to optimize the utilization of applied light by forming pyramidal second semiconductor in regions free from mask materials. CONSTITUTION:An n-type GaAs layer is formed on a high concentration n-type GaAs substrate 1. In this case the GaAs substrate uses the (001) plane. Then pyramidal dots are formed thereon. For the purpose, an SiO2 film 11 is formed as mask for processing, and rectangular openings with their sides being of <110> and <-110> are formed by photolithography. Subsequently, the SiO2 film 11 is removed, and an n-type GaAs layer 3', p-type GaAs layer 4, p-type AlGaAs layer 5 and high concentration doping p-type GaAs layer 6 are deposited in this order. Then the high concentration doping p-type GaAs layer 6 is removed from the pyramidal parts by photolithography to form a p-type electrode 7, and an n-type electrode 8 is formed on the rear face of the substrate. This makes it possible to enlarge the optical path length in the light absorption layer.

Title: Magnetic recorder
Inventor: KAMEI MASARU
IPC: G11B5/54
Filed: 1982-08-23
Abstract: PURPOSE:To prevent the generation of an error of the reset position of a head arm, by controlling the resetting speed of a spring of the head arm which is driven by a pinion unified with a gear to fit a pin of the head arm into the groove of the gear. CONSTITUTION:When a gear 30 is driven by a motor, a head arm 32 turns via a segmented gear 39 which engages a tooth lacking pinion 31 unified with the gear 30. Then a head 45 is pressed by a magnetic recording medium for writing or reading of information. Then the engagement is released between pinion 31 and gear 39 through the tooth lacking part of the pinion 31, and at the same time a pin 44 of the arm 32 is fitted into a groove 42 of the gear 30. Thus the resetting speed is limited for the arm 32 to which the resetting force is applied by a spring 33. As a result, the arm 32 is reset without generating vibrations due to an impact. Then the pin 44 is separated from the groove 42 via the sloping surface of the groove 42. In such a constitution, an error never arises with the resetting position of the arm 42.

IPC: G01B9/02
Filed: 1993-05-26
Abstract: PURPOSE: To enhance signal/noise ratio while ensuring the scanning distance by providing an attenuator in the reference arm of an interferometer thereby reducing the reference output. CONSTITUTION: An air gap is provided in an optical fiber 223 for an attenuator 240 and the fiber 223 is cut, at the opposite ends, at such angle as no reflection is introduced into an optical signal and polished.

Filed: 1984-07-16
Abstract: PURPOSE:To reduce the number of hardwares in a doubled processor, to generalize the processor and to use the processor as a multiprocessor by forming individual buses, a common bus, bus coupling circuits, etc. CONSTITUTION:When a CPUa included in a system 10 is to access a CPUa in a system 1m, the system No., outgoing trunk equipment No., etc. of the system 10 are outputted from the CPUa in the system 10 to an individual bus (e) in the system 10. A bus coupling circuit (d) in the system 10 discriminates that the specification is communication to another system and outputs data on the individual bus (e) in the system 10 to the common bus 6. At that time, a bus coupling circuit (d) in the system 1m detects an enabled system No. on the bus 6, sends the contents of the bus 6 to a bus (e) in the system 1m and activates a CPUa in the system 1m because the device No. is (a). Thus, communication between the devices can be unified in doubled constitution and an exclusive bus for each device connected between devices in both the systems is omitted, so that the number of hardwares can be reduced and the doubled processor can be generalized and used as a multiprocessor system.
