Title: Program searching method for magnetic recording and reproducing device or the like
Inventor: TAKITA YOSHIO
IPC: G11B15/087
Filed: 1986-05-26
Abstract: PURPOSE:To contrive coincidence between the video recording start position and the reproduction start position by detecting the recorded program searching signal by the 2nd program searching head in a fast feeding/rewinding mode and reversing the tape feeding direction after the tape is loaded for detection of the program searching signal through the 1st program searching head. CONSTITUTION:A tape is fast fed and rewound in a stop mode 4 and then stopped when the program searching signal is detected by the 2nd program searching head 6. Then the tape is fed in the reverse direction in a reproduction mode 3 and the fed in the forward direction when the program searching signal is detected by the 1st program searching head 5 for execution of the normal reproduction. Thus the coincidence is secured between the video recording start position and the reproduction start position. In such a way, the program searching signal can be detected by the head 5 and therefore a program searching action is also possible with the fast feeding/rewinding operations in the mode 3. As a result, the tape loading/unloading time can be omitted and the fast program searching operation is possible.

Title: Gear mechanism for timepiece
Inventor: SAWADA MIKIO
IPC: G04B13/00
Filed: 1987-05-20
Abstract: PURPOSE:To achieve a decrease in loss of energy with the lessening of the number of wheel train stages in a gear mechanism of a timepiece with a relatively large reduction ratio, by making teeth asymmetric in the geometry on the driving side to gain a large reduction ratio with the meshing of one set of gears. CONSTITUTION:For example, a drive gear 1 is arranged to be six in the number of teeth thereof and a driven gear 2 144 in the number of teeth so that the reduction ratio of one set of meshing gear exceeds 1:20 and moreover, the teeth of a drive side gear are made asymmetric in the geometry. With such an arrangement, while the teeth 1a of the drive gear 1 press the teeth 2a of the driven gear to send them 2a, the teeth 1b of the drive gear 1 enters between teeth 2b and 2c of the driven gear 2 without abutting them and then, the teeth 1b press the teeth 2b thereby assuring a smooth rotary motion. This enables the meshing of gears with a relatively large reduction ratio while reducing energy loss with a decrease in the number of stages of wheel trains to achieve a smaller size of the movement.

Title: Solid electrolytic capacitor
Inventor: IKEDA KONOSUKE
IPC: H01G9/00
Filed: 1988-05-20
Abstract: PURPOSE:To obtain a solid electrolytic capacitor in which the excellent adhesiveness between an anode oxide layer and a conductive polymer layer is provided and minute spaces are not formed between those layers by forming the oxide film layer and the conductive polymer layer on the surface of a metal substrate subjected to a surface roughing treatment at the same time. CONSTITUTION:Polymer having conjugated double bonds on its main chain can be used as conductive polymer. If an anode oxide film layer and a conductive polymer layer are chemically formed at the same time on the surface of a metal substrate subjected to a surface roughing treatment and the metal substrate is used as an electrode, the contact surface between the oxide film and the conductive polymer layer has sufficient unevenness. Therefore, by the increase of the contact area and adhesion strength and the reduction of the oxide film thickness, a capacitance for a unit volume of a capacitor can be increased and, moreover, the peeling-off between the oxide film layer and the conductive polymer layer can be suppressed, so that the degradation of the capacitance can be avoided.

Abstract: PROBLEM TO BE SOLVED: To minimize an influence of capacitance upon a single transmitted through a single line while limiting the voltage and current of the single by connecting a diode in series to a Zener diode between the single line and the ground. SOLUTION: On a Zener diode circuit part 2 side, a positive voltage bypath series circuit 9 which turns on when on-voltage is supplied in positive direction and a negative voltage bypath series circuit 10 in negative direction are provided. To the positive voltage bypath series circuit 9, diodes D1-D3 consisting of three silicon diodes are connected in series so that their polalities may be the same. To the negative voltage bypath series circuit 10, diodes D4-D6 consisting of three silicon diodes are connected in series so that their polarities may be the same. The whole junction capacitance of a diode circuit part 3 is small sufficiently, therefore, the whole junction capacitance of a Zener barrier 1 determined by the whole junction capacitance of the diode circuit part 3 can be reduced. It is thus possible to provide little influence of junction capacitance.
