Title: Zoom lens driving device for tv camera
Inventor: NAKAKISHI TOSHIO
IPC: G02B7/10
Filed: 1984-12-06
Abstract: PURPOSE:To decrease the required operating power for turning in the stage of a manual operation by interposing a centrifugal clutch mechanism which connects a driving motor and a drive transmission system when the rotating speed of the driving motor attains a specified value. CONSTITUTION:Electricity is conducted to the driving motor 40 to drive an output shaft 41 in the stage of an electrical driving operation. The output shaft 41 and a clutch drum 36 are then integrally rotated by the friction force acting between a clutch plate 42 and a clutch face 38 upon attainment of the rotating speed at which the centrifugal force acting on the plate 42 overcomes a compression spring 52. On the other hand, the plate 42 and the clutch face 38 are held in the non-contact state, i.e., the clutch is held disengaged during the non-driving of the motor 40. The rotation of a zooming ring 11 is simply transmitted up to the drum 36 and is not transmitted to the shaft 41 of the motor 40 when the ring 11 is manually turned. The rotation of the ring 11 with the light force is thus made possible.

Title: Musical sound signal generator
Inventor: OGI TOKIO
IPC: G10H1/057
Filed: 1987-10-14
Abstract: PURPOSE: To reduce the number of multipliers and to miniaturize the constitution of circuits by time-dividedly executing envelope coefficient multiplication and interpolating coefficient multiplication for musical sound waveform sampling value data by using a common multiplication means. CONSTITUTION: A multiplication means 15a is prepared in common to envelope coefficient multiplication and interpolation coefficient multiplication. A time- division control means controls time-divided supply and the means 15a executes multiplication between one of coefficients and musical sound waveform sampling value data generated from a musical sound waveform generating means WD and executes multiplication between the multiplied result and the remaining coefficient.  For instance, multiplication between musical sound waveform sampling value data generated from the means WD and an interpolation coefficient is executed at first so as to closely generate musical sound waveform sampling value data by interpolation and multiplication between the closely generated musical, sound waveform sampling value data and an envelope coefficient is executed by the same multiplying means to apply an envelope to a musical sound waveform sampling value data. Consequently the number of multipliers is reduced and the circuit constitution is miniaturized.
