Title: Audio signal storage and reproducing device
Inventor: TSUMURA MIOJI
IPC: G11B20/02
Filed: 1989-05-29
Abstract: PURPOSE:To reproduce high quality music in simple constitution by analog- converting a digital signal, storing it as it is in a tape recorder and reproducing it at a prescribed multiple speed at the reproducing time. CONSTITUTION:An A/D converter 2 and a D/A converter 8 are used for converting analog/digital information, functioning as a pair relation of them for each other, while a CPU 7 is operated to send the transmitted digital signals in turn to the D/A converter 8, so as to be used for control processing of a digital code series. The tape recorder 9 is functional as a storage device of the analog signal and a reproducing device, whereas the original waveform of an audio signal is reproduced from its waveform extended along a time axis by transmission in view of the required processing time at the transmitting time by varying the audio tape traveling speed at the storing time and the reproducing time respectively. By this method, the high quality reproducing sound can be obtained.

Title: Mask for screen printing
Inventor: MOCHIZUKI TATSUYA
IPC: H05K3/34
Filed: 1988-06-03
Abstract: PURPOSE:To contrive a lower fraction defective of products and higher reliability of soldered parts, by providing openings which have a high length/ breadth ratio and include openings differing in lengthwise direction, and controlling the area of the opening to different values according to the angle of the lengthwise direction of the opening to a squeegeeing direction (the same as the moving direction of a squeegee). CONSTITUTION:Openings 11a and 11c in a screen mask 1 have the same shape and the same lengthwise direction. Similarly, openings 11b and 11d in the mask 1 have the same shape and the same lengthwise direction. In these openings, the direction of the longer side is taken as the lengthwise direction. The lengthwise direction of the openings 11a, 11c is orthogonal to the lengthwise direction of the openings 11b, 11d. Each of the openings is rectangular in cross section, and the aperture dimensions thereof on the side for close contact with a substrate is equal to the aperture dimensions thereof on the side of squeegeeing. The cross section of each of the openings may be made to be, for example, trapezoid so that the aperture dimensions on the side for close contact with the substrate differ from the aperture dimensions on the squeegeeing side. A squeegee 2 moves in parallel to the lengthwise direction of the openings 11a, 11c to squeeze out a surplus creamy solder from openings parts of the screen mask.

Title: Cascode connection type differential amplifier
Inventor: TATEISHI MICHIKO
IPC: H03F3/34
Filed: 1988-06-01
Abstract: PURPOSE:To eliminate the deterioration in the frequency characteristic for a large amplitude of an input voltage by connecting an element which supplies a current flowing to each other between collectors of two transistors(TRs) constituting a differential stage. CONSTITUTION:A resistor 5 is connected between collectors of TRs 6, 7 of differential stage. When a difference between input voltages IN1, IN2 is large and the TR6 is turned off and the TR7 is turned on, since the bias of the emitter potential of a TR 4 is at a potential lower by nearly 0.7V from the potential of a bias power supply 12 and the base-emitter voltage of a TR 3 is nearly zero V, because the TR 6 is cut off and the emitter potential rises nearly to the potential of the bias power supply 12. That is, the emitter current of the TR 3 flows slightly through the resistor 5 and the emitter potential of the TR 3 is kept to a potential lower than the potential of the emitter power supply 12 by nearly 0.6-0.7V. Thus, the change in the collector potential of the TR 6 is less and the quantity of charge discharged when the TR 6 is turned on is less and the operation is quickened.

IPC: B41M5/26
Filed: 1985-06-24
Abstract: PURPOSE:To obtain excellent printing quality regardless of the surface smoothness of a transfer body, by attracting heat-meltable ink to the side of magnetized platen by using magnetic particles as a transfer medium. CONSTITUTION:The writing signal inputted by a thermal head 1 is converted to heat energy and the transfer layer formed to a substrate 2 is melted and receives the pressing of the thermal head 1 to be transferred to the surface of a transfer body 4 inserted between a platen 5 and the transfer layer 3.

At this time, said magnetic particles 3b transfer accompanied by the coloring substance 3a present in the periphery thereof. Because the transfer of the magnetic particles 3b by magnetic force is performed regardless of the surface smoothness of the transfer body 4, the coloring substance 3a accompanied by the magnetic particles 3b is well transferred even to a recessed part.

IPC: H01L21/68
Filed: 1990-05-28
Abstract: PURPOSE:To reduce chipping of a wafer in a holding member by providing a trench part at a position where the peripheral edge of the wafer makes contact with a roller. CONSTITUTION:A roller mechanism 12 is elevated such that two rollers 10 make contact with lower peripheral edge parts of a plurality of wafers 1 housed in a guide 2. Further, a motor 20 is driven to rotate the two rollers 10 in the same direction. The plurality of the wafers 1 are rotated in an annular groove part 13 owing to their contact with the annular groove part 13 provided in the rotating roller 10, the rotation of the wafers 1 being successively done until an orientation flat part goes to the lower side. As the orientation flat part and the roller 10 are separated away, the wafer 1 is automatically stopped in its rotation. After the orientation flat of all wafers 1 are completly aligned, the rotation of the motor 20 and hence the rotation of the roller 20 are interrupted. Lower ends of the wafer 1 are aligned with the pitch of the annular groove part 13, and once a wafer detector 30 is elevated, those lower ends are fitted in a groove part 32 of the wafer detector 30 without being brought into contact with the orientation flat parts of the plurality of the aligned wafers 1.
