Then, a Ga molecular beam and an Al molecular beam are projected on the substrate 3, and the mixed crystal AlGaAs is epitaxially grown. Under this condition, a film of about 500Angstrom  in thickness is grown and the Ga molecular beam and the Al molecular beam are shielded simultaneously while the As molecular beam is being projected. After the lapse of about one second, a shutter 11 is opened, the Si molecular beam emitted from an Si evaporation source 10 is projected on the Gaas substrate 3 for a fixed period, and an Si plane-doped layer is formed. Then, after the Si molecular beam has ben shielded, the Ga molecular beam and the Al molecular beam are projected on the GaAs substrate 3 after the lapse of one second. The above-mentioned procedures are repeated, and Al0.5Ga0.5As on which Si impurity atoms are doped in flat form is epitaxially formed on the substrate 3. Accordingly, the level of energy formed by Si donar atoms can be made shallow.

Title: Solid-state image sensing element and manufacture thereof
Inventor: ONO HIDEYUKI
IPC: H04N5/341
Filed: 1989-09-13
Abstract: PURPOSE:To make an isolating P<+> layer shallow by causing the whole width of a gate electrode to be substantially same as the width of a diffusion layer added by a read-out channel length. CONSTITUTION:An isolating P<+> layer 12 is formed after the formation of a transfer electrode and a gate electrode 4 used exclusively for transfer. At that time, the whole width of two gate electrode is caused to be substantially same as the width of an N-type layer 2 added by a read-out channel length. Then P<+> layer 12 does not diffuse so deep by a thermal process that it can be made shallow. Thus, the large decrease of the effective width of a vertical CCD due to lateral diffusion of the P<+> layer 12 can be suppressed.

Title: Bias limit circuit of avalanche photodiode
Inventor: NAKADA HIROAKI
IPC: H04B10/572
Filed: 1983-12-14
Abstract: PURPOSE:To keep the variable range of a multiplier rate of an avalanche photodiode constant independently of temperature change by limiting a bias voltage with a resistance value of a thermister provided near the avalanche photodiode. CONSTITUTION:A bias voltage generating circuit 2 applying a bias voltage Vb to the avalanche photodiode APD1 consists of a high voltage generating circuit 3 generating a prescribed voltage of several hundred volts, resistors 4, 5 forming the voltage Vb through the voltage division of an output voltage V0 from the circuit 3 and the thermister TH6. The resistance value of the TH6 is decreased when temperature rises, the change in the resistance value is relaxed by the resistor 4 so as to allow the combined resistance to be nearly linear against the temperature change. When the ambient temperature of the APD1 is elevated, the break-down voltage of the APD1 is increased. The resistance value of the TH6 is decreased in this case, the voltage dividing ratio of the output voltage V0 of the circuit 3 is changed, the voltage Vb is increased so as to compensate the decrease in the multiplier rate of the APD1 due to the temperature change.

Abstract: PROBLEM TO BE SOLVED: To radiate efficiently heat emitted from mounted parts by a method wherein a length of a PC card is made a length wherein its rear end is protruded from a card slot of a personal computer or the like, the mounted parts of a substrate is arranged at a rear end part, and the mounted parts are intensively bonded to a card box body with a heat conductive component. SOLUTION: A length of a PC card, when charged in a card slot 8 of a personal computer or the like, is a length wherein its rear end part 9 is protruded therefrom. Then, semiconductor elements 2 or the like are loaded intensively on a substrate 1 at the rear end part 9. A heat conductive sheet 7 consistinq of high heat conductivity material is made to lie between the semiconductor 2 and an inner face of the card box body 5 at the rear end part 9. Therefore heat generated in the mounted parts such as the semiconductor 2 or the like is transmitted to the rear end part 9 with the heat conductive sheet 7. Since the rear end part 9 is protruded from the card slot 8 when the PC card is charged in the card slot 8, its heat radiation to outside is efficiently carried out, and does not give an influence by radiation of heat on an inside of the personal computer or the like.

Abstract: PURPOSE:To extremely efficiently and economically perform separation, recovery, refining and condensation of each suspended component from a liquid containing various kinds of suspended matter by ejecting the source fluid comprising a fluid containing suspended matter in the perpendicular direction to a filter membrane, and alternately providing ejecting ports and discharge ports for circulation. CONSTITUTION:A cake layer depositing on the surface of a filter membrane is efficiently removed with a jet flow of the source fluid ejected from a fine ejecting port 8, which, as a result, increases the permeation flow rate. This cake layer is deposited in the process of separating a fluid containing suspended matter into the suspended matter and the liquid. In this process, the source fluid is ejected in the perpendicular direction to the filter membrane, and ejecting ports 8 and discharge ports 9 for circulation are alternately disposed. The ejection rate of the source fluid ejected is preferably about >=1m/sec, since, with the higher ejecting rate, the larger effect of scraping the cake layer is obtained.
