Title: Magnetic disk device
Inventor: SHIROYAMA KAZUHIKO
IPC: G11B17/04
Filed: 1984-03-09
Abstract: PURPOSE:To prevent the breakage of a magnetic head by inhibiting a shutter opening and closing mechanism from moving in a shutter opening direction during the ejection of a cartridge until a cartridge holder moving mechanism moves a cartridge holder almost to its nonengagement position. CONSTITUTION:When the cartridge 1 is inserted into the holder 18, the cartridge 1 moves forth while restrained between a holder base part 19 and presser plates 22 and 23, and the front end of the case 3 engages the pin 50 of a shutter opening and closing lever 47, so that the pin 50 enters a recessed part 9. The cartridge 1 is further inserted continuously to rotate a lever 47 clockwise, and the pin 50 presses a shutter 8 until its opening 8a coincides with the opening 6 of the case 3, so that the magnetic disk 2 is exposed. When the holder 18 further moves, a head support arm engagement part 23b is displaced and a head arm 14 is rotated with the force of a spring 15a, so that heads 11 and 12 enter a loading state wherein recording and reproduction are possible. In this case, the head 12 is lowered after the shutter 8 is opened completely, so the head 12 never strikes the shutter 8.

Title: Avalanche photodiode
Inventor: TORIKAI TOSHITAKA
IPC: H01L31/107
Filed: 1990-02-26
Abstract: PURPOSE:To make a rapid responsibility available by the method wherein at least a semiconductor of a narrow forbidden band width which contacts a hetero interface, in which the forbidden band width rapidly changes from wide to narrow, for example from the maximum value to the minimum, is composed of an indirect gap semiconductor in the semiconductor periodic structure. CONSTITUTION:In the ionization process by the hole, there is no condition in which both energy and wavenumber exist or such a condition slightly exist, if any. Therefore, ionization by a primary electron (1) selectively exists, generating secondary carriers (2), (2)'. In the periodic structure in which the forbidden band width linearly changes repeatedly, energy can be applied to electrons by conduction band discontinuity  Ec and a larger alpha/beta ratio can also be obtained utilizing an alpha>>beta characteristic unique to the indirect gap semiconductor by composing a narrow forbidden band width semiconductor area which contacts a hetero interface which gives  Ec with an indirect gap semiconductor. Moreover, a rapid responsibility can be obtained since an avalanche multiplication layer is in the semiconductor periodic structure in which the forbidden band width changes sloping downward.

Title: Construction method of bottom enlarged continuous wall
Inventor: WATANABE TOSHIO
IPC: E02F5/02
Filed: 1990-02-27
Abstract: PURPOSE:To obtain a bottom enlarged continuous wall of L-shaped cross section easily by lowering a bottom enlarging drilling machine along one side wall face of a drilled ditch, and interposing a guide member between the drilling machine and the other side wall face so as to enlarge the bottom of only one side wall face. CONSTITUTION:A bottom enlarging drilling machine 2 is lowered being shifted toward one side wall face 1a of a ditch 1. At this time, a guide member 3 is brought into contact with the other side wall face of the ditch 1 to hold the shift of the bottom enlarging drilling machine 2. When a drill rod 2a is rotated by a rotary table 5, only the side wall face 1a of the ditch 1 is enlarged at the bottom because of the axial eccentricity of the drill rod 2a. After inserting a reinforcing bar 7, concrete is further poured therein through a tremie pipe 5 to form a continuous wall. As a result, the continuous wall 9 with large supporting force can be formed within the very limit of a borderline without a protruding part, formed by the enlargement of the bottom, entering into the adjacent ground side.

IPC: H01L31/10
Filed: 1988-02-29
Abstract: PURPOSE:To make it possible to improve the responsiveness of the output signal (an electric signal) for an incident light by a method wherein at least either of impurity regions is formed on the region including the overhung wall surface formed in the vicinity of the region formed by leaving the prescribed interval. CONSTITUTION:A groove part 10, having both wall faces turned to overhung surfaces, is formed in the vicinity of the light-receiving region A of a transverse type light-receiving element, and an N-type impurity region 3 is formed on the region containing said groove part 10. As a result, the N-type impurity region 3 becomes as deep as the P-type impurity region 4 in the vicinity of the light-receiving region A, and accordingly, the large difference of the field strength in depthwise direction is removed. Moreover, as the wall surface of the groove part 10 has an overhanging form, the N-type impurity region 3 and the P-type impurity region 4 come closer as the groove becomes deeper. Accordingly, the electric line of force appearing between the N-type impurity region 3 and the P-type impurity region 4 appears in the form of a straight line.

Title: Manufacture of aluminum-water type heat pipe
Inventor: FUJINO KENJI
IPC: F28D15/02
Filed: 1984-03-12
Abstract: PURPOSE:To suppress corrosion reaction between aluminum and water and consequently improve the long term reliability of the operating performance of a heat pipe by a method wherein organic additive such as triethanolamine or the like is added to water in advance and, after that, the water is sealed in a vessel. CONSTITUTION:A water type heat pipe consists of a closed cylindrical vessel 2, which is made of aluminum or the surface of which is treated by boehmite process and in the interior of which wick 3 and working liquid 4 are sealed. The working liquid 4 is prepared by adding 0.05-2.5g/l of organic additive consisting of triethanolamine to ion-exchanged water or distilled water. When the heat pipe is in action under the temperature of 100-250 deg.C, the working liquid 4 and its stream turn to circulate within the interior of the container 2, resulting in producing dense boehmite film onto the inner surface part of the container 2. Because no hydrogen gas generates, no hydrogen gas stagnates in a condenser end as non-condensable gas and consequently no deterioration of the operating performance occurs, resulting in improving the reliability of the heat pipe.

Abstract: PURPOSE: To put a paper guide member into an opened position from a closed position without trouble so as to be able to take out jammed paper easily by providing an interference control means for driving a moving means on the basis of a jam detection signal and moving a paper regulating member into a non-interacting section. CONSTITUTION: Paper stored in a paper feeding device 3 is conveyed to an image forming part 2 through a conveying path 5 and then discharged outside of a device body 1. In case of double-side photocopying, on the other hand, the paper having passed the image forming part 2 is conveyed to an ADU tray 4 through a branch conveying path 5a, then merged into the conveying path 5 by an ADU paper feeding device 27 and refed to the image forming part 2. In case of a jam being generated, normal image forming action is stopped, and a moving rear end plate 22 positioned in an interference section A is moved forward into a position in a non-interacting section B. A user can therefore put a paper guide 7 in an open position without hindrance and remove jammed paper.
