Patent JP-H03248518-A (JP)
Title: Solid electrolytic capacitor
Inventor: MORIMOTO TAKESHI
IPC: H01G9/028
Filed: 1990-02-27
Abstract: PURPOSE:To obtain a solid electrolytic capacitor having small leakage current and stable performance by forming a solid electrolyte layer made of conductive polymer compound on an aluminum anode foil having 100mum-200mm of thickness. CONSTITUTION:A solid electrolyte layer made of conductive polymer compound is formed on an aluminum anode foil having 100mum-200mm of thickness. That is, since the foil used for an aluminum electrolytic capacitor is thin of several tens of microns, the foil is flexible. When it is used in combination with solid electrolyte, a leakage current is increased even by a small impact during manufacturing. Accordingly, the thickness of the foil is specified to remove this disadvantage, thereby reducing the leakage current. Thus, a solid electrolytic capacitor having small leakage current by the use of the conductive polymer compound as solid electrolyte and stable performance can be obtained.

Abstract: PURPOSE:To mount a center core securely by operating an energizing means by a control means and energizing the center core toward a recording medium loading surface, and mounting it on recording medium rotary driving part and then making the energizing member leave the center core. CONSTITUTION:When a cassette 1 is inserted into a cassette holder 22, a sensor operates and a cam wheel 36 rotates as shown by an arrow (a). A roller 33 which engages an outer peripheral cam 37 is pushed up according to the rotation, so the 2nd lever 27 rotates around a support shaft 17 counterclockwise. Consequently, the 1st lever 18 also rotates through a tension spring 30 and the cassette holder 22 moves down vertically. The 2nd lever 27 rotates successively and the center core 6 is energized by push pins 55a and 55b through a leaf spring 52 and pushed in a spindle 63, so that the center core is pressed against the top surface of the object projection 65 of a turntable 62. Then, the push pins 55a and 55b both leave the center core 6 from above.

IPC: H01L29/732
Filed: 1987-02-27
Abstract: PURPOSE:To make it possible to reduce burst noises without complicating the manufacturing process and without enlarging an element, by forming an emitter region with a polysilicon layer including impurities as a diffusing source, thereafter implanting impurity ions with the silicon layer as a mask, and forming an inner base. CONSTITUTION:Parts on emitter and collector contact forming regions of oxide films 24a and 24b, which are formed on a silicon substrate 19, are removed, and holes are provided. Thereafter, a polysilicon layer, in which donor impurities are doped, is formed. Then the silicon layer is patterned. Only a silicon layer 25a on the emitter forming region and a silicon layer 25b on the contact forming region are made to remain. Then heat treatment is performed. Donor impurities are diffused in the surface of a region 21 with the silicon layers 25a and 25b as diffusing sources, and N<+> type impurity regions 26a and 26b are formed. Thereafter, impurity ions are implanted with formed resist 27 as a mask. Then the silicon layers 25a and 25b are removed. Heat treatment is performed, and base regions 28a and 28b and an emitter region 26a are formed. Thus the manufacturing process can be simplified.

Abstract: PURPOSE:To improve the responsiveness by providing an oscillation-proof material on the edge of an oscillation transmission plate. CONSTITUTION:A coordinate input device constitutes an information input/output device of characters, graphics, images, etc., together with a display device 11' having a dot matrix display system or the like and is provided with an oscillation pen 3, an oscillation transmission plate 8, three oscillation sensors 6, etc. The transmission time of a longitudinal elastic wave transmitted from the oscillation pen 3 to oscillation sensors 6 through the oscillation transmission plate 8 is measured to detect coordinates of the oscillation pen 3 on the oscillation transmission plate 8. In this case, an oscillation-proof material 7 consisting of a synthetic resin or the like is set to the edge of one side to which sensors 6 are not set of the transmission plate 8 for the purpose of preventing the oscillation transmitted from the oscillation pen 3 to the oscillation transmission plate 8 from being reflected to the peripheral part and being returned toward the center. Thus, oscillation is absorbed and attenuated by the oscillation-proof material 7 to reduce reverberation as the whole.

Filed: 1991-03-11
Abstract: PURPOSE:To automatically synthesize connection data between logical circuits constituting multi-input adders, and to obtain the synthesizing method of the multi-input adders by which a high speed arithmetic operation can be executed. CONSTITUTION:Three input adders defining (i) as 3, are synthesized (step 2), the level of the (i) input adders is calculated (step 3-2), two terminals with which new full adders should be connected are selected in the order of the smaller level (step 3-3), the new full adders are connected with the selected two terminals, and the (i+1) input adders are obtained (step 3-4). Then, (i+1) is defined as (i), the steps 2, 3 and 4 are repeated until (i)=M can be obtained. When input data are 2 complement form, the number of expanded bits necessary for an overflow judgement is calculated, the circuits necessary for the overflow judgement are synthesized (step 4), and the unnecessary full adders are canceled (step 5). When the input data are positive integer form the overflow judging circuits are synthesized after the step 4 (step 6).

Title: Bus type optical network
Inventor: IMAI MITSUO
IPC: H04B10/077
Filed: 1987-02-27
Abstract: PURPOSE:To correct the ununiformity of an optical signal level from each station by using an active circuit to constitute a star coupler and to eliminate distribution losses substantially. CONSTITUTION:When a station 4i acts like a transmission station, an optical signal outputted from the said station is inputted to an input section 51 in an active star coupler 5, sent to an O/E 52, where the signal is converted into an electric signal and inputted in parallel with a decoder 54 and a signal interruption detection circuit 57. When the signal interruption detection circuit 57 judges the 'presence of signal'. Since an E/O 53i corresponds one to one to the station 4i, the dispersion in line loss between both at them is compensated easily by adjusting the output characteristic of the E/O 53i and nearly the same level of optical signal is supplied to the reception section of each station 4i.

Title: Tape taking-up method
Inventor: IMANISHI KIYOKAZU
IPC: B65H20/32
Filed: 1979-04-12
Abstract: PURPOSE: To prevent a tape from damaging by changing an air column tape loop according to the variation of a take-up diameter by winding the tape around a take- up reel.  
     CONSTITUTION: According to predetermined pattern 14, width H of an air column is varied corresponding to tape take-up diameter (d) measured by take-up reel 5. The tension of a tape generated in the air column is found by a fixed formula of the tape width, column width H, atmospheric pressure Pa, and column negative pressure Pc. As a result, varying column width H makes it possible to set the take-up tension of the tape corresponding to the variation of tape take-up diameter (d) of the take-up reel according to the predetermined variation pattern.

Title: Gate device
Inventor: ISHIYAMA HITOSHI
IPC: F16K3/314
Filed: 1993-03-05
Abstract: PURPOSE:To provide a lightweight and inexpensive gate valve of simple structure ensuring the prevention of such an accident as the break of a synthetic resin valve box or a valve body due to an excessive force at the time of valve closing, without use of an expensive and heavy valve rod bearing plate (striking member) made of metal such as stainless steel. CONSTITUTION:A valve stem 12 is coupled to a valve box 11 in such a condition as capable of rotation but not shiftable in an axial direction, and a valve body 13 is coupled to the valve box 11 in such a condition as capable of vertical shift but not rotatable. When a valve is closed, an excessive closing force prevention ring 30 moving in the same direction as the valve body 13 in a storage aperture 173 for an excessive tightening prevention mechanism formed in an upper bonnet 17, comes to strike against a stepped section 12F formed on the valve stem 12. Thus, the rotation of the valve stem 12 can be hindered and the valve body 13 can be prevented from coming down any more to generate an excessive valve closing force. According to this construction, excessive valve closing can be prevented without use of a valve rod bearing plate.
