Patent JP-H02302942-A (JP)
Title: Optical head device
Inventor: KUROSAKI MINORU
IPC: G11B7/135
Filed: 1989-05-17
Abstract: PURPOSE:To obtain a small-sized and inexpensive optical head device by providing a grating lens between a light source and a collimate lens. CONSTITUTION:In order to achieve the execution of one axis of an optical system, and to guide a reflected light from an optical disk surface 14 to photodetectors 23-25, a grating lens 18 is used. For the grating lens 18, a zero-th order diffracted light to be directly transmitted through the grating lens exists in addition to a primary diffracted light. The grating lens 18 is arranged between a semiconductor laser 1 light source and a collimate lens 4, and when the zero-th order diffracted light is used to a light to go from the semiconductor laser 1 to the disk surface 14, the same effect can be obtained as when a transparent plate equal to the thickness of the substrate of the grating lens 18 is simply inserted. On the other hand, to the reflected light from the disk surface 14, when the primary diffracted light is used, without using a half prism and a polarized beam splitter prism, an information light can be taken outside an optical axis. Thus, the grating lens is made to work as the beam splitter, and the small-sized and light-weight optical head can be composed.

IPC: H01L21/28
Filed: 1985-06-07
Abstract: PURPOSE:To improve the contact by using alkaline system etching liquid as etching liquid when the damage layer on the semiconductor surface after a contact hole has been formed. CONSTITUTION:After an N<+> type region 12 has been formed on the surface of a P-type surface of a semiconductor substrate 10 made by silicon, an insulative film 14 of silicon oxcide, etc. is formed on the surface of the substrate, and a photo-resist layer 16 having a hole corresponding to the desired contact hole is formed on the surface of the insulative film 14. Then, a part of the insulative film 14 is selectively removed with reactive ion etching to form a contact hole 14A, and to expose a part of the N<+> type region 12. After the photo-resist film 16 has been removed, the exposed surface of the N<+> region 12 is etch-removed with alkaline system etching liquid. Patterning is done by coating the surface of the substrate with electrode metal of Al or Al alloy to form an electrode layer 18 ohmically contacting with the N<+> type region 12 through the contact hole 14A, thereby providing highly reliable contact with low resistance.

Filed: 1977-10-18
Abstract: PURPOSE: To produce a device where the turn-off time can be shortened or the gate turn-off of the main current is possible by the reverse bias of the gate even in an amplifying gate-system SCR.  
     CONSTITUTION: In a PENBPBNE four-layer structure, control electrode 118 is surrounded by cathode 116, and auxiliary electrode 117 is intermediate between them. N-type auxiliary emitter layer 115 is formed under electrode 117 partially, and N layer 120 is formed under electrode 118 partially, and groove 121 is formed in PB layer 113 which extends from layer 120 to layer 115 opposite to layer 120. When anode 110 is defined as positive and the control electrode is defined as positive in respect to the cathode, the amplifying gate function effects normally to turn on because resistance RS of PB layer under groove 121 is large. When the control electrode is defined as negative in respect to the cathode, PB layer resistance R 2   under electrode 117 is approximately the tenth of PB layer resistance R 1  under  auxiliary Ne layer 115, and PB layer resistance R 3  under groove 121 is ten times as  large as R 2 . As a result, the residual carrier does not generate minority carrier  injection from the auxiliary emitter, and the residual carrier is led out from the control electrode through R 2 , therby turning off in a short time

IPC: C21B5/00
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To keep heat-flow ratio and gas utilizing ratio at a furnace wall part constant even in the case of increasing the consumption of fine granular raw material, by simultaneously executing both of the grain diameter of ore and the layer thickness ratio of ore/coke at the furnace wall part. SOLUTION: At the time of controlling the distribution of charged raw material into a blast furnace, a relation graph between the ratio of the ore layer height and the total layer height of the ore layer and the coke layer at the furnace wall part [Lo /(Lo +Lc )] and ratio of the grain size at the wall side and the average grain size of the ore (Dpwall /Dpave ), is drawn. An iso-FI line (coefficient of fluidizing) and iso-HFR line (heat flow ratio) are drawn on this coordinate. From this graph, the combination of the grain size at the wall side and the average grain size (Dpwall /Dpave ) and the ratio of the ore layer height and the total layer height of the ore layer and the coke layer at the wall side [Lo /(Lo +Lc )] along the iso-HRF line, is suitably decided.

IPC: A61L11/00
Filed: 1978-10-13
Abstract: PURPOSE: To effect perpetual disinfection of waste water by preventing disinfectant to be blocked together, a construction is provided to permit water to be treated to be always contained in a disinfectant reservoir installed at the internal, external, or both internal and external of the waste water container.  
     CONSTITUTION: In order for the disinfectant reservoir 10 to contain waste water with perpetual water level 8' even when the water level 8 falls in the waste water container, the height of the lower part of flow outlet 7 is made equal to the height of the side wall 12. Thus, the lower part of the disinfectant supply tower 4 is always immersed in the store water, preventing the disinfectant from being blocked and allowing it to be dissolved only to the saturated solubllity. As a result, when a large quantity of waste water overflows the top portion 12, the waste water mixes with store water in the bath 10 containing maximum concentration of disinfectant. Thus, the waste water undergoes complete disinfection and flows at the lower portion of the tower 4 to further effect disinfection.
