Title: Light transmitter for scanning distance measuring apparatus
Inventor: SHIRAKAWA HIROYUKI
IPC: G01S17/10
Filed: 1994-07-13
Abstract: PURPOSE:To obtain a small-sized light transmitter for scanning distance measuring apparatus which does not require high manufacturing accuracy. CONSTITUTION:A transparent plate 12 is arranged on the optical path between a light source 10 and a lens 11 for focusing the light therefrom to produce a parallel beam such that the transparent plate 12 can incline periodically against the optical path A. The light passed through a transparent plate 12 is deflected through refraction of the transparent plate 12 and thereby the light beam L1 leaving the lens 11 can be scanned by turning the transparent plate 12 in a predetermined direction. Since the transparent plate 12 can be disposed closely to a light source emitting the light radially, the transparent plate can be smaller than the lens. Furthermore, since the light beam L1 is not scanned with a large angle for the rotational angle of the transparent plate 12, high manufacturing accuracy is not required for the transparent plate and the like.

Title: Target for pickup tube
Inventor: ICHIBAGASE TAKESHI
IPC: H01J29/45
Filed: 1981-10-08
Abstract: PURPOSE:To realize a reduced baking and a reduced afterimage characteristic of a pickup tube by making a stabilizing film, which is provided on the electron- gun side surface of the photoconductive film of a target for the pickup tube, to have a two-layered structure consisting of a dense Sb2S3 film and a porous Sb2S3 film. CONSTITUTION:After a light-transmitting conductive film 2 is provided on a light-transmitting base plate 1 made of glass, an Se-system photoconductive film 3 which principally consists of Se and contains Te and As is formed on the film 2. After that, a two-layered stabilizing film 4 which consists of a dense Sb2S3 film 5 used as the first layer and a porous Sb2S3 film 6 used as the second layer is provided on the film 3 so that the film 4 has a thickness of 500- 5,000Angstrom , thereby making a target for an image pickup tube. Owing to the above constitution, since the dense Sb2S3 film 5 is not exposed on the side of an electron gun, discharge of secondary electrons is extremely small. In addition, since the dense Sb2S3 film 5 effectively prevents any scanning electron from entering into the photoconductive film 3, the generation of dark currents, bakings and afterimages can be reduced.

Title: Solid-state image pickup device
Inventor: OZAKI TOSHIBUMI
IPC: H04N5/335
Filed: 1985-07-24
Abstract: PURPOSE:To attain low noises by inserting a gate-earthed MOS transistor (TR) between a driver MOS TR and a load MOS TR to eliminate the Miller effect in a floating gate amplifier circuit. CONSTITUTION:When a signal charge transmitted through a CCD channel 2 is sent to a floating gate 3, the potential of the floating gate 3 is changed by electrostatic capacitance coupling. The potential fluctuation is amplified in terms of voltage by the 1st stage inverter circuit comprising MOS TRs 5, 6 and the amplified voltage is outputted through two source follower circuits of the next stage. A DC voltage is applied to a gate of a MOS TR 11 to suppress the Miller effect. Thus, the potential fluctuation at an output terminal B of an inverter is not capacitance-coupled to an input terminal A to suppress completely the Miller effect. Thus, the detection sensitivity is improved and low noise is attained.

Title: Switching power supply
Inventor: ABE TORU
IPC: H02M3/28
Filed: 1993-06-30
Abstract: PURPOSE:To reduce conduction/radiation noise by suppressing the common mode noise current flowing through the impedance transformer line capacitance of a common choke coil connected in series with a rectifying circuit. CONSTITUTION:A small-sized thin transformer for high frequency switching power supply has increased line capacitance and thereby the common mode noise current increases. In order to suppress noise caused by the common mode noise current, a common mode choke coil 9 is inserted between the secondary winding 32 and a rectification diode 41. Since the common mode coil 9 is inserted in series into a path through which the common mode noise current flows, the common mode noise current is suppressed by the impedance thereof. This circuitry allows efficient reduction of conduction noise and radiation noise.

Title: Method for coiling steel sheet
Inventor: HASEGAWA HIROSHI
IPC: B21C47/26
Filed: 1993-06-30
Abstract: PURPOSE:To effectively prevent lap marks from being generated by nipping a top end part of a steel sheet between thermosetting resin sheets just before coiling the steel sheet from a rolling line, pushing heated dies on the steel sheet and press forming the resin sheet into a tapered shape on the top end part of the steel sheet. CONSTITUTION:Pressing surfaces of dies 23 (surfaces facing to a steel sheet) are made into tapered surfaces with their interval gradually narrowed downstream. Since resin sheets 28 arranged on the front surface and rear of the coil tip part of each die 23 are pressed by heated tapered dies 23 from upper and lower directions and press-formed into a tapered shape so that a coil end is smoothly formed without steps, and an adhesive strength enough to prevent stripping can be obtained. In this case, since the resin sheets 28 at the tip part of the steel sheet have elasticity and steps are absorbed by the sheets 28 a lap mark is not generated on the steel sheet of a second and succeeding turns. Therefore, the lap mark is practically eliminated at the time of winding the steel sheet by treating the tip part in this process before coiling.
