Title: Transverse pnp transistor
Inventor: AKIOKA TAKASHI
IPC: H01L21/331
Filed: 1987-02-27
Abstract: PURPOSE:To improve the rapid operating properties of a PNP transistor, by diffusing dopants for a base and an emitter from the same surface for forming a base width. CONSTITUTION:A base width is formed by introducing dopants of an emitter 4 and a base 5 transversely from the side walls of steps provided on a semiconductor substrate 1. Thus, the dopants are introduced through a mask of photoresist or the like, so that an N<+> layer 8, a P<+> layer 7 and a P layer 6 are provided. A material having desirable resistance to oxidation is deposited on the whole surface and then anisotropically etched so as to leave the sidewalls 13 on the steps on the substrate surface. Thermal oxidation is carried out for providing an oxide film having a thickness of about 0.1-0.3 mum on the region except the sidewalls. The sidewalls are then removed by means of phosphoric acid or the like. Through the aperture formed thereby, N-type and P-type dopants are successively introduced so as to form the base 5 and the emitter 6, respectively. In this manner, a PNP transistor capable of operating at a high speed can be obtained.

Title: Loop code fft computing system
Inventor: KAWADA SHINYA
IPC: G06F17/14
Filed: 1990-02-26
Abstract: PURPOSE:To shorten processing time by increasing only the capacity of a program replying to a purpose by describing prescribed plural sets of butterfly arithmetic operations as a continuous processing program, and executing a butterfly arithmetic operation group processing means to execute the operation repeatedly. CONSTITUTION:The prescribed plural sets of butterfly arithmetic operations are described as the continuous processing program, and they are executed repeatedly. In other words, in a first butterfly arithmetic operation group processing means 203, processing is executed only by performing addition and subtraction essentially since it is frequently observed that a complex coefficient multiplied by every input goes to a simple real number or imaginary number, and in a second butterfly arithmetic operation group processing means 205, four sets of butterfly arithmetic operations are described as the continuous program. Furthermore, in a deformed butterfly arithmetic operation processing means 207, such control that no waste half of output by the arithmetic operation is calculated, and no calculation of data corresponding to a higher harmonic component at a higher terminal side is performed by a third repetitive processing means 206 is applied. Thereby, it is possible to shorten the processing time by increasing only the capacity of the program replying to the purpose.

Title: Switch device
Inventor: TERAMAE KATSUHIRO
IPC: H01H9/54
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To provide a switch device which can decrease the number of output lines with respect to the number of switch elements. SOLUTION: A signal conversion part 10 is structured so that a voltage generating means consisting of a resistance type voltage-dividing circuit is connected with the output end of each switch output L1-L4 of an AT switch SW, and the voltages at the voltage-dividing points of the resistance-type voltage-dividing circuits, i.e., middle point voltages L1'-L4', are added by an adder 11, and then the output voltage therefrom Vout is transmitted in the form of single signal to a signal processing part from an output terminal.  Because the combination pattern of the switch output can be identified by the DC voltage level, transmission to the outside can be made by the voltage level of the single signal, and it is possible to connect with an external signal processing circuit using three lines including a line to supply the power and a common ground line regardless of the number of switch elements, to lead to a reduction of the cable costs.

Title: Electric charge brush for electrophotographic device
Inventor: KONDO MITSUHIKO
IPC: G03G15/02
Filed: 1987-02-27
Abstract: PURPOSE:To provide resistance to a permanent set to dead folding a brush for a device for electric charging of the brush so that the decrease in contact pressure on the surface of a photosensitive body is prevented and the uniform electric charge is executed on the surface of the photosensitive body by previously subjecting said hair of the brush to skewing in one direction. CONSTITUTION:The entire length of the hair 2 of the brush 3 is previously inclined in one direction with respect to the surface of the photosensitive body 4; i.e., the hair is subjected to the skewing. The hair 2 is positioned diagonally with respect to the line passing the center of the shaft 1 of the brush 3 and the rotary shaft of the body 4 when the brush 3 is brought into contact with the surface of the body 4 if the brush is previously subjected to the skewing in such a manner. The forces for the contact are then dispersed over the entire length without being concentrated only to the hair tips 2 as in the conventional manner. The contact of the air 2 with the surface of the body 4 is attained by the elasticity of the hair over the entire length thereof. The resistance to the permanent set to dead folding is thereby provided to the brush and the decrease in the contact pressure with the body 4 is greatly prevented.

Title: Method and device for dispatching control
Inventor: HAMANO TAKEO
IPC: G06F15/177
Filed: 1990-02-22
Abstract: PURPOSE:To attain the highly efficient dispatching control without causing such the case where a CPU is occupied by a specific processing unit in a simple logic by providing an execution processing unit storage means and a CPU queue changing means. CONSTITUTION:The processing units P1 - P3 are queued into a CPU queue storage area 1, and the unit P1 is stored in an execution processing unit storage area 6 when the P1 is under execution. Then the P1 waits for an event and releases a CPU 2 and queued from the queue. When a fixed time elapses and an execution processing unit storage means 7 is called out. Thus only a name is stored in the area 6 without changing the CPU queue due to the difference caused between both units P1 and P2. Then the execution of the P2 is carried on and the means 7 is called out again. Thus the P2 of the area 1 is compared with the P2 of the area 6. Then a CPU queue changing means 5 is called out when the coincidence is obtained between both units P2. Thus the P2 and the P3 are switched to each other, and the CPU 2 is given to the P3.

The laser light is separated into two, passed through a cell in a sample chamber and filtered. Then, the wavelength and intensity of the light absorbed by a sample gas are detected and a relation of frequencies and intensities is displayed.
