Title: Electric power amplifier
Inventor: TAKOZATO MASAYUKI
IPC: H03F3/30
Filed: 1979-06-13
Abstract: PURPOSE:To reduce greatly the notching distortion by increasing forcedly the base voltage of one transistor of the composite NPN transistor and then securing the conduction for the composite transistor with a low level of voltage to compensate the turn-on delay time. CONSTITUTION:In accordance with the AC input signal applied to the base of the driving step transistor (TR)Q2, the conduction and the breaking are given alternately between the composite NPNTR of Darlington-connected TRQ5, Q<6> and the composite TR of PNPTRQ4 plus NPNTRQ6, Q9 each, and then the amplified signal is supplied to speaker SP. The base voltage of TRQ6 is increased forcedly although the turn-on delay time may occur when TRQ5, Q8 are broken with TRQ4 conducting. As a result, the conduction can be secured for TRQ6, Q9 with the lower voltage than the voltage needed so far to give the conduction to TRQ6, Q9. Accordingly, the turn-on delay time can be compensated for the composite TR of TRQ4 plus Q6, Q9 to give an extreme reduction to the notching distortion.

Title: Impurity doping method
Inventor: HAYASHI HIROSHI
IPC: H01L21/208
Filed: 1982-04-30
Abstract: PURPOSE:To control impurity concentration accurately when an n gtowth layer to which Te is added is obtained by using a compound of a IV group element and Te as an impurity raw-material and doping Te to a growth layer. CONSTITUTION:When the n type growth layer in which Te is added onto a semiconductor substrate is acquired through a liquid phase epitaxial growth method, the compound of the IV group element and Te is used as the impurity raw- material. A substance such as tin telluride (SnTe) or lead telluride (PbTe) is used as the compound of the IV group element and Te. Weighing is facilitated owing to the atomic weight of the IV group element. The electron concentration of a Ga0.5Al0.5As growth layer in the case when Ga, Al or GaAs as the impurity and 0.133mg SnTe as a growth raw-material are liquid-grown on the substrate is 1X10<18>cm<-3>, a very small amount of approximately 0.067mg mush be added when a metal Te is used as the impurity raw-material in order to obtain the same electron concentration, and weighing and addition are facilitated up to approximately twice when SnTe is used as the raw material. The crystallinity, surface homology, etc. of the n type growth layer grown while employing SnTe as the raw material are quite the same as those of a layer using the metal Te.

Abstract: PURPOSE:To set a printing page securely by turning a page through the movement of a roller by curling only an opened page up toward a binding part by a difference between the frictional force of a friction roller to a page surface and the frictional force of a paper surface. CONSTITUTION:A friction roller 13 while pressing on a bankbook 1 moves toward a bankbook binding part 1a in the middle of the bankbook 1.

As the roller 13 moves, the roller is rotated counterclockwise an shown in the figure by the recoiling force of the curled page 1b and the roller 13 enters under the reverse surface of the floating page 1b. Here, the roller 13 returns by moving in the opposite direction. Simultaneously, the bankbook 1 also moves toward a bankbook entry hole 27. Thus, the pages of  the bankbook 1 are turned over automatically in the forward and backward directions.

Title: Scan controller for scanning type copying machine
Inventor: TAKAHASHI MASAHARU
IPC: G03G15/043
Filed: 1989-03-27
Abstract: PURPOSE:To eliminate the restriction caused by the device constitution by the arrangement of a paper sensor by delaying the starting time of scanning by means of a carriage by prescribed time and, at the same time, setting the scanning time in corresponding to the size of an original when the original has a special size. CONSTITUTION:When an original 2 has a regular size, a controller 17 calculates the scanning time corresponding to the size of the original 2 and moves the carriage in accordance with the calculated scanning time. After the carriage scans the original 2 for the prescribed time from a reference point C for exposure, the controller 17 returns the carriage 16 to its home position. When the original 2 has a special size, the controller 17 delays the scan starting time of the carriage 16 by the difference between the time t1 required for feeding paper 11 to a transferring position B from a paper sensor 13 and the time t2 required for moving the surface of a photosensitive body 9 to the transferring position B from an image forming position A and returns the carriage 16 to the home position after the carriage scans the original for the scanning time corresponding to the size of the original 2. Therefore, the arrangement of the paper sensor 13 does not restrict the device constitution and, in addition, scanning can be performed effectively irrespectively of the sizes of the original 2 and paper 11.

Title: Radiation detecting device
Inventor: NAKANO KATSUSHI
IPC: G01J5/38
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To heighten the efficiency of detecting an infrared ray or the like. SOLUTION: The incident infrared ray is absorbed by a detecting film part 4 and converted into heat. As a result, the temperature of a poly-silicon film 6 doped to n-type forming a part of the detecting film part 4 rises so that the film 6 is thermally expanded. As both sides of the film 6 are supported by leg parts 3, the compressive stress is generated in the film 6. By the piezo- resistance effect produced by the stress, electric resistance between both side parts of the film 6 is decreased. Simultaneously, by the bolometer effect produced by the temperature rise of the film 6, the electric resistance of the film 6 is decreased. Further, as the sectional area of the film 6 is increased by the compressive stress, the electric resistance of the film 6 is decreased.  By three causes, a decrease in the electric resistance of the film 6 due to the temperature rise is brought so that the change amount of the electric resistance of the film 6 is enlarged and the detection efficiency can be heightened.

Filed: 1991-04-08
Abstract: PURPOSE:To provide the learning machine requiring short time for initial value setting and learning. CONSTITUTION:A first initial value calculation part 30 calculates the initial value of the threshold value of a first intermediate unit 3 in advance as follows. An average vector calculation part 31 calculates the average vector of a category against all input vectors to be learnt and a distance calculation part 32 calculates the distance between the input vector and the average vector of the category of the input vector. Then, a first initial value decision part 33 calculates the maximum value of the distance by category from the distance between the average vector of each category calculated by the distance calculation part 33 and the input vector, and decides the maximum value to be the initial value Ri0 (i=1 to N, i: first output unit number) of the threshold value of the category at its output to a unit generation part 23. Thus, the initial value of the threshold value of the first intermediate unit 3 can be decided based on the stretch of data from the center of gravity of the learning vector by category when the first intermediate unit 3 is generated so that the excess time for deciding the initial value setting can be shortened.
