IPC: G02B6/42
Filed: 1986-11-18
Abstract: PURPOSE:To easily and quickly align the optical axis of a semiconductor PN junction element to that of an optical waveguide without damaging by moving the semiconductor PN junction element by probe opening/closing mechanisms to align the optical axis. CONSTITUTION:Movement of a PN junction element 1 is controlled through a heat sink 23 by probe opening/closing mechanisms 42 and 42' consisting of conductive materials and is controlled by a probe opening/closing mechanism 43 which is orthogonal to mechanisms 42 and 42' and consists of a conductive material. Optical axes of the element 1 and optical waveguide 16 and 16' are aligned if laser beam from optical waveguides 16 and 16' of an optical module are made incident and the element 1 is positioned so that the indicated value of a selecting level meter 15 between probes 41 and 40 connected to mechanisms 43 and 42 is maximum, and in this state, the optical module which fixes the heat sink 23 and a waveguide 18 is generated. By this optional axis alignment free from thermal and mechanical stress, the optical axis of the semiconductor PN junction element is easily and quickly aligned to that of the optical waveguide without damage.

IPC: B29C45/70
Filed: 1997-10-06
Abstract: PROBLEM TO BE SOLVED: To mold a lens of high quality with high shape accuracy. SOLUTION: In an injection compression molding method for molding a lens by injecting a molten resin into a mold constituting member 45 having a lens molding cavity 3, a runner 49 and a sprue 48 to compress the same and cooling the lens to take out the same as a molded product, closed control is performed in an injection process so that the actual injection speed of the molten resin from the start of injection filling becomes first and second presset speeds in the section up to this side of a gate part and the section from this side of the gate part to a cavity. Further, open control is performed so that the injection speed of the molten resin becomes a third set speed in the section from the cavity to the completion of injection filling.  After injection, the lens taking-out temp. of a lens convex surface molding cavity forming member (lower mold insert 12) is controlled so as to become lower than that of a lens concave surface molding cavity forming member (upper mold insert) to take out a lens molded product.

Title: Image forming device
Inventor: KATO KOICHI
IPC: G03G21/00
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To attain consecutive photographing of an original image in the main scanning direction without the need for a large memory capacity. SOLUTION: In the case of multiple consecutive photographing mode where plural original images are arranged side by side in the main scanning direction, image data outputted from an optical read section for each one main scanning line are sequentially stored in a line memory 62 having at least a memory capacity of one main scanning line and the stored data are outputted sequentially from the line memory 62 and an image is formed on an image forming medium based on the output data. In this case, the image data are stored with divisions in the line memory 62 by number of arranged original image data. Since the plural image data of one original image are stored in the line memory 62 during one main scanning line, the plural original images are consecutively photographed in the main scanning direction. Since the memory capacity of the line memory 62 is enough to be one main scanning line, no large memory capacity is required.

Title: Compressor
Inventor: IKEDA WATARU
IPC: F04C29/00
Filed: 1990-10-15
Abstract: PURPOSE:To improve abrasion resistance and reliability of a compressor by forming a nitrification part whose surface roughness is set to a prescribed value or less on a crankshaft and constituting a bearing member from a bronze- sintered layer impregnated with ethylene tetrafluoride and lead. CONSTITUTION:A compressor is equipped with a nitrification part 27 formed through the nitrification processing and surface treatment on the outer peripheral part of a covering body 15, and the inner peripheral part of a bush 28 which slidingly moves with the outer peripheral part of the covering body 15 is constituted of a bronze sintered layer 30 impregnated with ethylene tetrafluoride and lead. Accordingly, even in the high frequency operation with high operation frequency higher than the commercial-used power source frequency or in the low frequency operation having the lower operation frequency than the commercial used frequency, the abrasion resistance between the covering body 15 and the bush 28 can be improved. Further, the surface roughness of the nitrification part 27 is set to 1.0-S or less, and since the bronze sintered layer 30 which is formed by the impregnation with ethylene tetrafluoride and lead for the nitrification part 27 is combined, the initial fittness between the covering body 15 and the bush 28 can be improved.

Title: Edp document spool switching system
Inventor: KAJIWARA KAZUNAO
IPC: G06F9/06
Filed: 1988-10-28
Abstract: PURPOSE:To reduce the manhour of operation by automatically outputting an EDP document temporarily outputted to a system spool to a user's spool or leaving the EDP document in a system spool file by changing an output class. CONSTITUTION:An operating system (OS) 1 receives an output request from a user program 2, stores an output document 12 to a system spool file 10 and stores the information of an output class table 18 and an output document table 19 in an output generation information file 3. A spool switching control means 9 commands a reading means 6 to read out the output document 12 from the file 10, decides a document header data 13, and when the data are an object to be processed, commands a writing means 8 to output the document to a user spool file 14. When the data are not the object, the contents of the output class table 18 in the OS 1 are changed by an attribute changing means 7. Since the change of executive control document on user program is not complicated and the spool of the output document is also easily changed, the manhour of operation is reduced.

Title: Output circuit using transistor
Inventor: MASUDA JIRO
IPC: H03F3/34
Filed: 1987-10-28
Abstract: PURPOSE:To enable the ON/OFF control of load while power consumption at the time when the load is normal is limited by providing a diode to supply a current through the load to the base of a first transistor(TR) connected to the load in series through a second TR. CONSTITUTION:At normal time that the short-circuit of the load 11 does not occur, the current for load control is supplied to the first TR 1 through a resistor r2 and the second TR 2. The diode D1, connected in relation to the second TR and the load, comes conductive when the load 11 short-circuits, and the current through the load 11 is given to the base of the first TR 1 through the second TR 2, and a large current flows in the first TR 1. But, since this current need not be a large value too much, the resistance value of the resistor r2 can be selected to be large. Thus, the power consumption by the resistor r2 and the power consumption by the first TR 1 are limited, and in addition, the large current can be flowed in the first TR 1 at the time of the short-circuit of the load.
