Filed: 1994-02-22
Abstract: PURPOSE:To prevent the leaking current with electron mobility being kept sufficiently high in the ON state by alternately laminating three or more layers of first semiconductor layers comprising InAlAs and second semiconductor layers, wherein the electron affinity is larger than InAlAs and Fe is doped in a buffer layer, and achieving high resistance. CONSTITUTION:First semiconductor layers 103 comprising InAlAs in a buffer layer 104 become the depletion layers. The residual carriers in the layers are acquired in second semiconductor layers 102, whose electron affinity is larger than InAlAs. The resistance of the first semiconductor layer 103 becomes high. Fe is doped in the second semiconductor layer 102. Therefore, the residual carriers from the first semiconductor layer 103 are captured at the deep acceptor level formed of Fe and compensated. Thus, the resistance of the second semiconductor layer 102 also becomes high. Since three or more semiconductor layers are laminated in this way, the diffusion of the Fe is sufficiently trapped, and an FET, wherein the electron mobility in the channel layer is high and the high-resistance buffer layer is provided, can be obtained.

Abstract: PURPOSE:To make it possible to manufacture the title photoprinter heads with a favorable yield and low cost by connecting a plurality of light emitting elements, which belong to a set, with one output pad of a driver IC, while making a plurality of light emitting elements which are adjacent as a set. CONSTITUTION:For example, if two light emitting elements 28a, 28b are made a set, and electrodes on one side of these light emitting elements are jointly connected with one output pad 30 of a driver IC 26, data is applied at the same time to both light emitting elements 28a, 28b of the set from the driver IC 26. However, since the other electrode of each light emitting element is respectively connected with a different wiring, and either wiring is selected, and only the light emitting element which is connected with the selected wiring is operated. By selecting light emitting elements included in a set while shifting in order, even when a pad on the driver side (an output pad of a driver IC) for a set of light emitting elements is jointly used, different light emitting elements can be individually controlled.

Title: Defrosting controller
Inventor: ATSUMI AKIRA
IPC: F25D21/06
Filed: 1979-03-02
Abstract: PURPOSE: To prevent variation of starting timing of defrosting by a method wherein the static pressure difference at both sides of an evaporator upon completion of defrosting is memorized as an initail value every time when normal operation is started.  
     CONSTITUTION: A differential-pressure detection unit 7 detects the static pressure difference in unfrosted condition, based on the detection values fed from static- pressure detectors 5 and 6 arranged in the ducts in front of and in the rear of a cross-fin tube type evaporator 4 in a refrigerating cycle, and the static pressure difference is memorized as an initial value in a memory unit 8. The differential pressure detected by the unit 7 increases as the frosting on the evaporator 4 progresses; a defrosting operation is started when the difference between the detected differential pressure and the initial value has exceeded a set value. The setting of the initial value is effected by memorizing the temperature and humidity during operation as well as the differential pressure in unfrosted condition and under fouling of the evaporator 4. Thus, wrong detection of frost amount can be avoided, and the starting timing of defrosting can be determined according to the frost amount.
