Title: Blower
Inventor: HIRAISHI SHIYUNICHI
IPC: H05K3/26
Filed: 1981-03-16
Abstract: PURPOSE:To provide a blower which can simultaneously send fluid in the opposed two directions by disposing reverse twisted auxiliary blades on the external periphery of blades which build up an axial flow fan. CONSTITUTION:Blades 2 having a twist angle alpha radially extend from a boss member 1a which is joined with a rotation shaft of a driving motor and the external ends of those blades 2 are encircled with an annular casing 3. Auxiliary blades 6 additionally extend from the external periphery of the annular casing 3. A twist anlge beta of each of the auxiliary blades 5 is made in the opposite direction to the twist angle alpha. When a blower 7 is turned in the arrow direction, a flow is produced in the direction of a one-dot line by the blades 2 and simultaneously another fluid runs in the direction of a two-dot line by the auxiliary blades 5.

Title: Automatic document feeder
Inventor: OUCHI TOSHIAKI
IPC: G03G15/04
Filed: 1990-02-20
Abstract: PURPOSE:To make the torque of a drive source for a resist roller carrying document the irreducible minimum of a demand by providing a pick-up means in such a way as to be capable of being rotated to the direction of picking the documents up when the pick-up means driven by the drive source is out of action. CONSTITUTION:A device is provided with a pick-up means 36 picking documents up out of a document tray 33, a separation means 38 separating the documents one by one from the pick-up means 36 so as to carry them, a drive source 56 driving the pick-up means 36 and with an one-way mechanism 53 which is provided for the pick-up means 36 in such a way as to lie between the pick-up means 36 and the drive means 56. In the second place, when a resist roller 40 starts carrying each document delivered ahead, the pick-up means 36 is freely rotated by the one-way mechanism 53. This thereby permits load applied to each document being carried to be reduced, thereby making the drive source 56 of the pick-up means 36 small in size and light in weight, while the life of the pick-up means 36 is lengthened.

Title: Cordless telephone system for mobile communication
Inventor: SATO KAZUO
IPC: H04W76/02
Filed: 1989-02-17
Abstract: PURPOSE:To prevent the generation of radio interference disturbance inherent to a cordless telephone system for mobile communication by determining a secondary carrier frequency between a master set and a slave set with primary carrier frequency. CONSTITUTION:The size of a communication area between the master set and the slave set is extremetely small as compared to the sizes of small radio zones (a) to (c), the range of high possibility for the generation of radio interference disturbance is included in the same small radio zones (a) to (c) and a mobile station 10 for the same primary carrier frequency signal does not exist in the same small radio zones (a) to (c). Namely, the primary carrier frequency for an incoming line or an outgoing line between a mobile telephone base station 20 and the master set is received by the master set and the slave set, the received signals are respectively divided at their frequency and directly utilized as a 1st local oscillation signal for forming a secondary carrier for executing transmission/reception between the master set and the slave set. Consequently, a secondary carrier frequency components are not overlapped in a communication enable range between the master set and the slave set and radio interference inherent to the cordless telephone system can be evaded.

Title: Optical path network configuration method
Inventor: HAMAZUMI YOSHIYUKI
IPC: H04B10/07
Filed: 1994-03-09
Abstract: PURPOSE:To reduce a setting time and the number of wavelengths by setting an optical path so as to minimize the number of accommodated optical paths of an optical transmission line and reducing the number of multiple wavelengths by 2nd setting in the optical communication network where wavelength multiplex optical cross connectors are connected by the optical transmission line. CONSTITUTION:The optical communication network in which wavelength multiplex cross connectors 1-9 having plural nodes are interconnected by corresponding optical transmission lines 11-22 is controlled by an optical path controller 41. For example, an optical path 31 or the like of the shortest path minimizing the number of accommodated optical paths accommodated in the transmission lines 11-22 is set as a current path between a start point 33 and an end point 34. Similarly, an optical path 32 being a bypass with a few standby optical path accommodation number is set as a standby path to each of the transmission lines 11, 12, 15, 20. Furthermore, as to optical paths maximizing the number of multiplexed wavelengths, a current path and a standby path are set again to decrease the number of wavelengths. The setting time is reduced by the method with less setting number and the number of multiplexed wavelengths is reduced.

IPC: G11B7/005
Filed: 1991-02-12
Abstract: PURPOSE:To detect a recording mark without the interference with the recording marks before and after the recording mark and without being affected by a crosstalk from adjacent recording marks. CONSTITUTION:The regenerative signal 15 of a recording signal 11 is differentiated in a differention circuit 1 to obtain a derivative signal 16. The derivative signal 16 is binarized in a first comparator circuit 3 and a second comparator circuit 4 with voltage V1 and V2, respectively, to obtain outputs 17 and 18. The outputs 17 and 18 are synthesized in a detector circuit 6 and a synthetic signal 19 is sampled with a clock signal 20 whose phase is deviated by 180 deg. from the center period of the recording mark to obtain a detection signal 21. When '1' is detected as the detection signal 21, the output immediately after the detection is changed to '1'; when '-1' is detected, the output immediately after the detection is changed to '0'; and when '0' is detected, the output immediately after the detection is changed to the output preceding to it. Thus, the regenerative signals 22 can be obtained.

IPC: H03K19/0175
Filed: 1981-03-20
Abstract: PURPOSE:To increase drivability and then the degree of integration, by setting the input NAND of a CMOS 2 at one input end of a CMOS output buffer circuit  via a CMOS inverter and at the same time the input NOR of a CMOS 2 to the  other input end, respectively. CONSTITUTION:The W/L (W: channel width; L: channel length) of a CMOS output buffer circuit 1 is set so that the external capacity can be driven. If the W/L of a P.MOS and an N.MOS is set at 10/6 and 5/6, respectively, the W/L of the P.MPS and N.MOS is required to be set at 10/6 and 5/6 at an inverter 4 to drive the P.MOS. As a result, the sufficient driving is possible although the W/L of a CMOS NAND circuit 2' is small. Thus the W/L can be reduced to eliminate the picture area and then to increase the degree of integration.

Title: Deficiency analysis of semiconductor element
Inventor: NISHIOKA SUNAO
IPC: H01L21/66
Filed: 1980-03-26
Abstract: PURPOSE:To detect fine deficiency quickly and accurately by processing a fluorescent image generated through excitation with ultraviolet rays irradiation to a resist pattern after it is taken with a TV camera. CONSTITUTION:An automatic feeding mechanism 2 is loaded with a monitoring sample after a resists wire 8 is arranged in the same direction as a horizontal scanning of TV. Ultraviolet rays are radiated to irradiate a resist wiring pattern through a microscope 3 and the reflected light and the excited fluorescence are partially magnified. Only a fluorescent image undergoes a photoelectric conversion and the video signal is processed to be displayed on a CRT6. The resist wire 8 having a defect 10 differs from an SiO2 film in the video image depending on whether there is fluorescence or not. Then, after a binary conversion, the video signal is set at the level ''1'' from a defect up to the end of scanning by implantation and then, the level ''1'' is canceled from a SiO2 portion by image reduction, leaving a level SIGMAS in portions based on the defect 10. The existence of the defect is defected depending SIGMAS. This method enables an accurate and quick study on how a defect develops.
