Title: Autodyne receiver
Inventor: OKASHIN YAMATO
IPC: H04B1/22
Filed: 1985-02-26
Abstract: PURPOSE:To obtain the selectivity and the stability equal to a super heterodyne system by providing plural tuning circuits and connecting a negative impedance converting circuit to at least one tuning circuit out of them. CONSTITUTION:An antenna tuning circuit 1 is composed of a bar antenna coil L1, a capacitor C1 and a variable condenser C2. To the output edge of a high frequency amplifier 2, an inter-step tuning circuit 3 is connected, and further, to the output edge of the tuning circuit 3, a negative impedance converting circuit 4 is connected. Since a sharpness Q of synthesization of the tuning circuit 3 and the negative impedance converting circuit 4 is larger in proportion to the receiving frequency, a band width DELTAf of the synthesization goes to be constant regardless of the receiving frequency, and the selectivity also goes to be constant regardless of the receiving frequency. Further, since the sharpness Q needed as a whole is obtained by two tuning circuits 1 and 3, the large sharpness Q is not needed respectively to tuning circuits 1 and 3, and especially, concerning the tuning circuit 3, the positive feedback is not executed, the sharpness Q is made larger by the negative impedance converting circuit 4 and therefore, the sufficient stability can be obtained.

Title: Clock driver circuit
Inventor: ASAZAWA HIROSHI
IPC: H03H19/00
Filed: 1988-02-19
Abstract: PURPOSE:To prevent the off-set voltage of an operational amplifier from being increased by a clock stopping condition for a long time by adding respective multi-phase clock to one input of a two-input OR, which corresponds to the phase number of the multi-phase clocks, commonly connecting the other input, obtaining it as a reset terminal and respectively obtaining clock outputs from the respective two-input ORs. CONSTITUTION:Both two-phase output clocks phi1' and phi2' are caused to be high level by causing a reset terminal 2 to be the high level when a multi-phase clock generating circuit 1 is in the stopping condition and the selecting switches of a switched capacitor circuit are closed. Thus, for an operational amplifier input in the switched capacitor circuit, both a plus input and a minus input are connected to a ground. Accordingly, even when a clock driver circuit is left for a long time in such a condition, unbalance is not generated in a pair transistor, which goes to be the input differential pair of the operational amplifier. Thus, the off-set of the operational amplifier can be prevented from being increased.

IPC: H04N1/113
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To avoid image quality deterioration at joints of image formation areas by light beams in an image forming apparatus having a split type light scan apparatus incorporated therein. SOLUTION: When spots of laser beams shift by one scan line in a sub scan direction at a joint of image formation areas as shown in Fig. (A), each light source is controlled to modulate and project light beams on the basis of image data of scan lines shifted by one line at the same time point as shown in Fig. (B). When spots shift by 0.5 pixel in a main scan direction at the joint of image formation areas as in Fig. (A), a projection start timing of one light beam is shifted by a scan time corresponding to 0.5 pixel from a projection start timing of the other light beam, whereby the shift amount in the main scan direction is corrected. In this manner, the shift in the main scan direction is eliminated as indicated in Fig. (C).

IPC: F16D69/04
Filed: 1992-02-25
Abstract: PURPOSE:To facilitate the production of a friction material excellent in corrosion resistance and bond by immersing a nitrided back metal in a ethanolamine anionic surfactant of a specified pH to form a rust-preventive film on its surface and bonding it to a friction member. CONSTITUTION:A back metal is surface-nitrided, cooled, washed, and immersed in an ethanolamine anionic surfactant of a pH of 8-9 and a concentration of desirably 1-5wt.% to form a rust-preventive film on its surface. The back metal is washed with water, coated with an adhesive, and bonded to a friction member to obtain a friction material. This process is simple as compared with the conventional process comprising nitriding a back metal, immersing it in a lowly viscous rust-preventive oil and degreasing it with a solvent such as trichloroethylene or methyl ethyl ketone. If the pH of the anionic surfactant is below 8, the back metal after the immersion turns purple.

Filed: 1978-03-31
Abstract: PURPOSE: To increase current-surge resistance by varying an interval between an auxiliary gate and a cathode electrode corresponding to that between the outer circumference of main SCR and the auxiliary gate when the latter has a difference partially or entirely.  
     CONSTITUTION: The distance between the outer circumference of main SCR 1 and auxiliary gate electrode 9 is the largest, L 1 , at notch 11 and L 1 >L 2  at any other place. Distance l 1  between auxiliary gate electrode 9 at the part of distance L 1  and cathode electrode 7 is greater than distance l 2  at the part of distance L 2 . Namely, the relation of l 1 >l 2  is born corresponding to the relation of L 1 >L 2 . At the optimum ratio between l 1  and l 2 , it is ideal that the power loss of Si between electrodes 9 and 7 becomes nealy uniform at the entire circumference. Then, L 2 /L 1  and l 2 /l 1  vary with the sheet resistance of electrode 9, but they can be calculated. As a result, the current-surge resistance improves.
