Title: Semiconductor photodetector
Inventor: SUGIMOTO YOSHIMASA
IPC: H01L31/10
Filed: 1986-05-30
Abstract: PURPOSE:To realize a speedy and highly sensitive semiconductor photodetector by a method wherein a super-lattice lamination of first and second semiconductor layers stacked up alternately is installed on a side of a light absorbing layer opposite to the side a light-receiving layer is formed, the semiconductor layers are in specified relations with each other in terms of forbidden band width, thickness, and reflection coefficient, and the semiconductor layers satisfy prescribed conditions when exposed to light of a specified wavelength. CONSTITUTION:A super-lattice lamination wherein first and second semiconductor layers 1 and 2 are alternately positioned is installed on a side, opposite to the side mounted with a light-receiving surface, of a light-absorbing layer. A first semiconductor layer 1 has a forbidden band width Eg1, thickness d1, and reflection coefficient n1: and a second semiconductor layer 2 has a forbidden band width Eg2 (Eg1>Fg2), thickness d2, and reflection coefficient n2 (n1<n2). The first and second semiconductor layers 1 and 2 satisfiy d1=lambda /4n1 and d2=lambda /4n2, respectively, where lambda is a specified wavelength. This supper-lattice layer is provided under an light-absorbing layer and serves as a reflector. It follows therefore that, even when the thickness a light- absorbing layer of a conventional design is reduced from about 5mum to about 2mum, there will be no largescale reduction in the quantum efficiency because light not absorbed once will eventually be absorbed after reflection from a black reflector.

Title: Radiation shielding structure of refrigerator
Inventor: FUKUI NAOKI
IPC: G01R33/035
Filed: 1989-05-17
Abstract: PURPOSE:To restrain the generation of eddy current harmful to magnetic flux measurement with a gradiometer by using material wherein the heat dissipating ratio of a radiation shield to cut off the input of radiation heat into the gradiometer is low, and the thermal conductivity is high, and forming slits at some parts of the material. CONSTITUTION:Since a radiation shield 28 is provided with slits 29, 30, the inside and the outside of the radiation shield 28 are linked by them. Vacuum exhaust for discharging air from a vacuum vessel 1 is enabled in a matter of minutes. Since the shield 28 is made of material of high thermal conductivity, the inside can be cooled in a matter of minutes. The cooling time of a gradiometer can be reduced. Since the shield 28 is made of mateiral of low heat dissipating ratio, the shielding effect of radiation heat input to the gradiometer can be effectively secured. Even in the case where the shield 28 is made of electrically conductive material, the generation of eddy current loop of the radiation shield 28 caused by magnetic induction is restrained by the slits 29, 30. Thereby noise caused by the eddy current can be reduced, and the magnetic flux mesuring sensitivity of the gradiometer can be kept high.

Title: Digital signal transmitting method
Inventor: AMANO YOSHINORI
IPC: H04N7/173
Filed: 1988-05-25
Abstract: PURPOSE:To make the interval between a transfer requesting pulse and transfer starting pulse freely selectable depending upon apparatuses by transmitting N pieces of data as one unit between the apparatuses and causing a master and slave sides to respectively output a transmission signals and transfer requesting pulse signal, and then, fixing the time from the transfer starting pulse signal to starting of data irrespectively of the apparatuses. CONSTITUTION:Data are transmitted as one unit in digital signals between a sound processing section 1, communication processing section 2, and data processing section 3 and the buffer memory section 5 of a file device 4. In case the device 4 sends a transfer requesting signal to the processing section 1 and, when the section 1 is set to the transferring state upon receiving the requesting signal, the section 1 returns an answer signal to the device 4. Then the device 4 sends a transfer requesting pulse to the processing section 1 and the section 1 returns a transfer starting pulse signal to the device after the lapse of time T1. After time T elapses from the transfer starting pulse signal, N pieces of data are continuously transmitted. Thus the process starting time of the processing sections 1-3 is fixed.
