Title: Grating of optical pickup device
Inventor: MURAKAMI MASANORI
IPC: G02B7/28
Filed: 1989-08-02
Abstract: PURPOSE:To facilitate the production of gratings and also to simplify the adjustment of the space between gratings and the rotational angle of the grating by attaching the 1st and 2nd gratings to both sides of a transparent substrate having the thickness equal to only a Talbot distance. CONSTITUTION:A 1st grating 13 having the black/white stripes which are parallel and equidistance to each other with a pitch (d) is attached to the upper surface of a substrate 12 consisting of the parallel transparent glass or plastic planes of thickness (t). At the same time, a 2nd grsting 13a having the black/ white stripes with the parallel and equidistant pitches (d) is attached to the rear surface of the substrate 12 with a tilt angle alpha to the stripe of the grating 13. Thus a grating member 10 is obtained. The thickness (t) of the substrate 12 is set at a Talbot distance T. Thus the Fourier image of the grating 13 is put on the grating 13a and therefore clear moire stripes are obtained. As a result, the adjustment is simplified at assembling and at the same time the number of parts can be decreased.

Title: Changing method for key arrangement for multifunction telephone
Inventor: BANDOU HIROAKI
IPC: H04M1/00
Filed: 1981-12-15
Abstract: PURPOSE:To minimize the quantity of data to be set, by providing previously storing data of standard keys and then changing only desired areas. CONSTITUTION:Multifunction telephones STA A and STA B are controlled by a microprocessor MPC which performs connection control of a telephone switchboard SW. The processor MPC is connected to an ROM, C-RAM provided with battery backup and an N-RAM having no battery backup, respectively. Then a process is executed by a program of the ROM. The switchboard SW is connected to a call repeating trunk TRK. Both clear key K06 and display key K13 are fixed keys among the keys K00-K15 of the telephone, and a change of functions is impossible for these two keys. Therefore these keys are combined with other keys and used, and a state display and deletion are carried out for each key. Thus the quantity of data to be set can be minimized by setting the standard data only for the key to which a change is desired.

Further, since a stopper mechanism consisting of the stopper 12, ring 13, and the groove 3a for ring is installed, the slip-off of the movable gear 8 to the top edge direction of the rotary shaft 3 is prevented. Besides, the slip- off of the movable gear 8 due to abrasion, etc., of the gear parts is prevented.

Title: Setting method of electrostatic charge current
Inventor: MOTOHASHI MITSUO
IPC: G03G5/08
Filed: 1984-09-26
Abstract: PURPOSE:To set exactly electrostatic charge current without laborious operations by segmenting a photosensitive body for each of the thickness range of the specified photosensitive layer and setting a specified electrostatic charge current value for each of the segments. CONSTITUTION:The thickness of the formed photosensitive layer is preliminarily measured and is segmented by each of the layer thickness ranges. The segments are ranked and the adequate electrostatic current value is set for each of the ranks. To assemble a copying device, the operator checks first the rank display of the photosensitive body 1, measures the quantity of the electrostatic charge current flowing between the photosensitive base body 1a and the earth with a microammeter 3 while discharging electricity from an electrostatic charge electrode 2 to charge electrostatically the photosensitive layer 1b and matches the current value with the electrostatic charge current value of the corresponding rank by regulating a variable resistor RV. The setting of the electrostatic charge current is thus extremely easily and efficiently executed.

Title: Safety device for alcohol quality changing gas engine
Inventor: HIROTA TOSHIO
IPC: G01P13/02
Filed: 1981-12-17
Abstract: PURPOSE:To greatly reduce the temperature of quality changing gas which is emitted when a safety valve is operated, by disposing heat absorbing substance in the way of a passage which connects the safety valve and a quality changing gas supply passage, thereby improving the safety. CONSTITUTION:A pressure of quality changing gas which is emitted from a quality changing device 4 into a quality changing gas supply passage 7 is applied  to a pressure receiving surface of a valve body 23 from a quality changing gas inlet 28 via porous sheets 26 and 27 and a heat absorbing substance 25. If the pressure is normal, in other words, yield to a force of a spring 22, the valve body 23 is closed while if the pressure thereof is excessively increased over a set  value, the valve body 23 is raised so open a valve hole 21 so that the quality changing gas is emitted from a quality changing gas outlet 29. The quality changing gas thus emitted is greatly reduced due to the heat absorbing effect of the heat absorbing substance 25, on account of which the safety may be improved.

IPC: H01L21/033
Filed: 1984-09-28
Abstract: PURPOSE:To freely regulate size ratios in the thickness direction and horizontal direction as desired by forming at least two dielectric isolation layers in different thicknesses having self matching property. CONSTITUTION:After removing a silicon oxide film for buffering, the n<-> type epitaxial layer 43 is etched to the desired depth with a soltion such as KOH, etc. Next, a silicon oxide film 55a is formed to the area to be etched. Simultaneously, the high concentration boron-added polycrystalline silicon layer 47 exposed from a second silicon nitride film 48 is also oxidized. This silicon oxide film is removed by etching, and the first silicon nitride film 44 is also removed by etching. In this case, the nitride film 48 is also removed and thereafter the polycrystalline silicon layer 47a is also removed. In this timing, the base-collector contact isolation region is covered with the silicon oxide film for buffering and is not etched. Next, with the remaining first silicon nitride film 44 used as mask, the isolation region is oxidized. Hereafter, a transistor can be formed by the existing method.

Filed: 1985-09-13
Abstract: PURPOSE:To omit a special resin removing mold when tie bars are cut and to prevent cracks from occurring in the resin, by providing the tie bars in close proximity to resin sealing parts, partially removing the thick part of the cutting part of each tie bar, and reducing the area of the cutting part. CONSTITUTION:A semiconductor element mounting region 4 is located at the center. Leads, whose tips have noble metal plated films 3, are linked with tie bars 1.
