Title: Video signal amplifier circuit
Inventor: TERADA NORIO
IPC: H04N5/18
Filed: 1990-11-13
Abstract: PURPOSE:To reduce a time when a video signal is settled to a normal output by implementing charging of a capacitor of a DC voltage level setting circuit even during non-blanking period of a horizontal synchronization clamp pulse just after application of power till the end of charging. CONSTITUTION:An output of a video signal amplifier 61 is compared with a reference voltage VREF at a comparator 62 and its output receives negative feedback synchronously with a horizontal clamp pulse (HCLP) at a switch 64. The HCLP is given to a terminal 11 of a changeover circuit B1 and when a level at a terminal 16 is H and the HCLP is at L, a power supply voltage (V) 71 equal to the H level of the HCLP is selected. Just after application of power, a terminal 17 is at an L level and the V 71 is outputted to a terminal 14, the switch 64 is thrown to the position (b), a capacitor 66 is charged by an iBLK and when the level reaches the voltage VREF, the video signal is outputted. Thus, a frequency divider ratio of a frequency divider circuit B2 is set to 1/N and the capacitor 66 is continuously charged even for non-blanking period of the HCLP to reduce the settling time when the video signal reaches a normal output to 1/6.

Title: Electrophotographic sensitive body
Inventor: MURAKAMI MUTSUAKI
IPC: C08L83/00
Filed: 1988-12-05
Abstract: PURPOSE:To obtain a ZnO photosensitive body having high sensitivity and durability by using a specified polymer as binder for the ZnO photosensitive body. CONSTITUTION:A high molecular compd. expressed by the formula I is used as binder for a ZnO photosensitive body. In the formula I, each R1-R4 is an 1-7C alkyl group, or an aryl group including groups derived from phenyl, naphthyl group, etc.; n is an integer >=2. The binder comprising the high molecular compd. consists of a polysilane constituted of Si as principal chain having itself relatively high photoconductive characteristic. Therefore, the photosensitive characteristic of a ZnO photosensitive body is improved by using the binder. Moreover, the residual potential is lowered. Since the compsn. has film forming capacity, a photosensitive layer can be formed without using a conventional binder resin. Since the compsn. has high heat stability, a photosensitive layer having high durability is obtd.

Consequently, when the glass melt is cooled, a coating film for preventing the composition components of the glass melt from vaporizing is formed on the surface of the glass melt. When the additive is SiO2 , the amount of the SiO2 used is preferably 0.1-4.0wt.% based on the glass raw material. When the additive is H3 BO3 , the amount of H3 BO3 is preferably 0.1-3.5wt.% expressed in terms of B2 O3 based on the glass raw material.

Title: Cutting tool
Inventor: OKAWA MASAYUKI
IPC: B23B27/00
Filed: 1999-10-28
Abstract: PROBLEM TO BE SOLVED: To improve the machining accuracy of a cutting tool by limiting a drop in its flexural rigidity and its chatter vibration. SOLUTION: A tool body 2 has a concave groove 14 cut in an external surface 3b of a head portion 3 between a peripheral cutting edge 10d and the back of the head portion 3. A shank portion 4 has an internal hollow blind hole 18 passing a center axis O. In the section taken just across the axis, the ratio Sa/Sb in the sectional area Sa of the blind hole 18 to the sectional area Sb of a thick-walled portion 19 of the shank portion 4 is set in the range of 0.2 to 1.3. This range ensures flexural rigidity and increases the natural frequency in cutting operations to thus diverge the natural frequency and the frequency of external force from a work from each other or suppress resonance.

Title: High-tension load switch
Inventor: CHISAKI SHINICHI
IPC: H01H33/64
Filed: 1991-09-12
Abstract: PURPOSE:To prolong the durability and enhance the reliability, of the contact and reduce the operation force and miniaturize/lightweighting the switch case, by providing a dynamic contact formed of a slide contact block and a static contact formed of a power supply rod. CONSTITUTION:To bring the contact from its closure to its off-condition, a connecting rod 3 is moved to the load side by a link mounted to the box. When a center rod connected to the rod 3 is moved, a static contact 360 at a tip end of the center rod is first electrically disconnected. But, since a circuit is formed by a dynamic contact, generation of arc on this surface does not occur. When the center rod is further moved, the contact rod is disconnected from an initial winding of the coil of a slide contact block 309. At this time point, a coil is formed to generate a magnetic force. When the block 309 is disconnected completely from the block, the magnetic force becomes the highest.

Abstract: PROBLEM TO BE SOLVED: To reduce a camera-shake correction residual component, due to temperature fluctuation or a change with respect to passage of time in a camera-shake sensor. SOLUTION: The camera is made up of a camera-shake correction signal generating means 40 which receives a sending output from a camera-shake sensor 18 fitted to a camera main body, a camera-shake correction means 22 receiving the camera-shake correction signal, a motion vector detection means 70, a calibration signal generating means 36 receiving a motion vector, and a gain adjustment means 38 that adjusts a gain of the sensing output based on a calibration signal Sc. The gain of the gain adjustment means is adjusted based on the calibration signal Sc, so that the motion vector obtained by picking up an image of a test object approaches unlimit to zero. Since the motion vector component includes a fluctuating component of a sensing output due to a temperature fluctuation or a secular change in the camera-shake sensor, the camera- shake correction residual component due to the fluctuation component of the sensing output due to the temperature fluctuation or the change with respect to passage of time in the camera-shake sensor is reduced through the calibration processing.
