Abstract: PURPOSE:To reject field-through and to make the operation stable, by electrostatically shielding between a floating electrode and a transfer electrode with an electode applied with DC voltage. CONSTITUTION:A floating electrode 44 is electrostatically shielded with a transfer electrode 42 against AC voltage with an electrode 43 supplied with a DC voltage from a DC power supply terminal 33, then the transient effect of the pulse voltage phi2 applied to the transfer electrode 42 is not almost given. Thus, the potential variance of the floating electrode 44 is caused due to the variance in the phi2 pulse, and the floating electrode 44 is always operated stably independently of the signal charges. Pulse voltages phi1, phi2, phi3 are applied to terminals 31, 32, 35, and at time t0, signal charges 60, 61 are present beneath the transfer electrode 38, 42, at time t1, charges are shifted right, and at time t2, the signal charge 60 are transferred beneath the electrode 40 and the charge 61 is transferred beneath the floating electrode 44 and stored, and they are read out externally from a terminal 51 via an amplifier 50.

Title: Optical-output-wave discriminating apparatus
Inventor: FUJISAWA TAKANORI
IPC: G01M11/00
Filed: 1989-04-24
Abstract: PURPOSE:To make it possible to specify a light source by outputting the light which is reflected and returned from a first output part through second and third output parts in correspondence with the kinds of the polarized light. CONSTITUTION:For example, a normal light wave P which is inputted from a normal-light-wave input terminal 23 is converted into an abnormal light wave S. Thereafter, the light is reflected from a cut point 26. A light wave S which is reflected from the cut point is refracted in calcite 19 in a non-polarization type light isolator 12 at a refractive angle (a). The light advances in the calcite 19. The polarization plane is turned by negative 45 degrees in a 45-degree quartz optical rotator 19. Then, the polarization plane of the light wave S is turned by positive 45 degrees in a Faraday rotater 16. As a result, the direction becomes 0 degree. The light wave S under this state is inputted into calcite 18. The light wave S is refracted at a refractive angle (a) in the calcite 18 and advances. The light wave S is outputted from an abnormal-reflected-light- wave output end 27 through a polarized-wave preserving fiber 21. Thus a light source can be specified.

Title: Video signal circuit
Inventor: KOYAMA HIDEAKI
IPC: H04N5/44
Filed: 1989-04-21
Abstract: PURPOSE:To prevent deterioration in picture quality by inputting a video signal superimposed with a triangle wave, generating a triangle wave signal synchronously with the triangle wave, using a differential amplifier to eliminate the triangle wave and setting a level of a pulse tip of a horizontal synchronizing signal to a fixed level with a clamp circuit. CONSTITUTION:In order to generate a triangle wave signal synchronously with. a triangle wave of a video signal A inputted from an input terminal 2 and superimposed with the triangle wave, a comparator 1 compares a reference voltage Vref with the video signal A to form a pulse signal B. A triangle wave generating circuit 4 generates a triangle wave signal C with the same phase as that of the triangle wave superimposed on the video signal A synchronously with the pulse signal B generated from the comparator 1. A differential amplifier 5 receives the video signal A at its noninverting input terminal and outputs a shape signal D resulting from the video signal A superimposed with the triangle wave signal subtracted from the triangle wave. Thus, the capacity of a coupling capacitor at the input of a clamp circuit 7 is increased independently of the capability of eliminating a triangle wave of the clamp circuit.

Title: Heat transfer recording medium
Inventor: SHIMAZAKI RIYOUICHI
IPC: B41M5/26
Filed: 1984-05-22
Abstract: PURPOSE:To prevent a recording paper from being contaminated, by a construction wherein a lubricant solid at normal temperature and melted when being heated by a thermal head is made to separate out at the surface of a heat- fusible ink layer. CONSTITUTION:The lubricant must be capable of being mixed in a heat-fusible ink layer, be solid at normal temperature, be heat-fusible, separate out upon solidification of the ink layer, and have such a melting point that it is melted when being heated by a thermal head. The amount of the lubricant used is preferably 1-20pts.wt. per 100pts.wt. of the dried weight of the heat-fusible ink exclusive of the lubricant. If the amount of the lubricant is excessively large, the ink layer as a whole becomes crystalline, and scaling of the ink layer occurs. If the amount of the lubricant is less than the above range, the desired effect can not be obtained. Accordingly, since the contact frictional resistance between the surface of the ink layer and a recording paper is markedly lowered, printed images are not easily broken even when being rubbed by fingers or the like, and durability of the printed images can be enhanced.
