Title: Camcorder
Inventor: KAWAI KAZUYA
IPC: H04N5/232
Filed: 1992-01-08
Abstract: PURPOSE:To zoom sound smoothly together with a video image by controlling an AF microcomputer by means of a continuous zoom position signal from a zooming encoder and controlling a zooming microphone, too. CONSTITUTION:By manual or electrical zooming, a zooming position is converted into voltage in a zooming encoder 1 to which reference voltage (I)3 and reference voltage (II)4 are applied to obtain an analogically continuous zoom position signal 2. With the zooming position signal 2, an auto focussing (AF) microcomputer 5 conducts the control of the position and speed of a focussing motor and transmits a control signal to the focussing motor terminal 6. Surrounging sound is picked up with a built-in microphone and amplified by a microphone amplifier 8 as a sound signal. The amplified sound signal is controlled by the continuous variable voltage of the zooming position signal 2 and attenuated to a sound level corresponding to the zooming position by a attenuator 9.

Title: Manufacture of silver halide photographic emulsion
Inventor: HIOKI KATSUHIKO
IPC: G03C1/015
Filed: 1990-01-08
Abstract: PURPOSE:To enhance sensitivity, graininess, and storage stability by forming silver halide grains composed essentially of twins, and specifying temperature in extracting the gelatin used as a hydrophilic protective colloid and its transmittance. CONSTITUTION:The silver halide grains to be used are composed essentially of the twins and the gelatin to be used as the hydrophilic protective colloid is extracted at a temperature of 38 - 65 deg.C and regulated in its transmittance to >= 90%. The silver halide grains of the emulsion are grown in the presence of the gelatin. The transmittance of the gelatin is enhanced by removing contaminants by filtration or by using hydrogen peroxide or the like to bleach it, thus permitting the obtained silver halide photographic emulsion to provide a silver halide color photographic sensitive material high in sensitivity and superior in graininess and good in storage stability.

Title: Tire reinforcing material and pneumatic tire
Inventor: TAKAHIRA KOJI
IPC: D02G3/48
Filed: 1999-01-06
Abstract: PROBLEM TO BE SOLVED: To provide a tire after vulcanization with an inflection point of load- extension characteristics by twisting a tire reinforcing material composed of wire rods such as filaments or cords in such a state as continuing a part having a plurality of different crimp rates in the longitudinal direction. SOLUTION: This reinforcing material is constituted of a part having a plurality of different crimp rates, namely a substance formed by crimping into a composite shape and having large wave parts 3a and small wave parts, alternately containing at every prescribed length without overlapping each other across the whole longitudinal length of a filament 1a (or a cord, etc.). The material is thus provided with a plurality of inflection points in load-extension characteristics. A pneumatic tire using the reinforcing material at least in a ply can be thus provided with the inflection point after the vulcanization, even if one of the inflection points of the reinforcing material is near a lift rate in tire vulcanization, held flexibility by the effect of crimping in a low load range, and suppress the extension of the reinforcing material itself.

Title: High-alumina refractory
Inventor: AMANO HAJIME
IPC: C04B35/101
Filed: 1995-01-09
Abstract: PURPOSE: To reduce the cost of high-alumina refractory by recovering the less- contaminated part from a used high-alumina refractory article, crushing and sieving the recovered refractory and compounding with a powdery refractory component to form a monolithic refractory. CONSTITUTION: A porous plug having a truncated conical form and made of a high-alumina porous material is used in a steel-making process and taken out when the length of the plug is shortened to an unusable level. The tip 13 of the used truncated conical porous plug 1 is lost by melting and the adjoining part 12 is infiltrated with molten steel. A chisel is applied to the boundary between the infiltrated part 12 and the non-infiltrated part 11 and struck with a hammer to apply an impact force to the plug and the broken steel-infiltrated part 12 is removed to recover the non-contaminated high-alumina refractory. The recovered high-alumina refractory is crushed and the particle size is adjusted to obtain aggregate having a prescribed particle diameter.  A monolithic refractory is produced by compounding the aggregate with refractory components such as alumina powder and mullite raw material and stirring the mixture.

Title: Rotary sealing device
Inventor: YUMOTO WATARU
IPC: F16J15/34
Filed: 1995-01-10
Abstract: PURPOSE: To provide a rotary sealing device with which a problem is not caused even if a co-rotating phenomenon is presented under a high pressure and high speed rotation condition by installing a synthetic resin-made substancially rectangular cross sectional sealing ring in contact with a motional surface of a mating member and a slip ring on a shaft directional side surface on the pressure receiving side of the sealing ring by combining them with each other. CONSTITUTION: Fluid pressure P enters an installing groove from a clearance between a side surface 13 of a sealing ring 11 and a side surface 5 of the installing groove, and acts on a peripheral surface 15 corresponding to an outer peripheral surface of the sealing ring 11 and the side surface 13 on the pressure side, and brings a motional side peripheral surface 12 of the sealing ring 11 into close contact with a rod surface 2, and acts so as to press a slip ring 21 to a side surface 6 on the pressure receiving side of the installing groove 4.  When high pressure is applied, the sealing ring 11 is put in a co rotating condition of rotating together with a rod 1, but at that time, since it becomes relative motion between a side surface 14 on the pressure receiving side of the sealing ring 11 and the slip ring 21, abrasion is hardly caused, and a frictional resistance value between the sealing ring 11 and the slip ring 21 also becomes a small value.

IPC: G01S13/88
Filed: 1997-01-09
Abstract: PROBLEM TO BE SOLVED: To exactly survey the position of an underground pipe with a pipe locator by reducing magnetic noise effects. SOLUTION: In a gas pipe 12 buried underground, alternating current is supplied from an oscillator 13 via a cable 14. Around the gas pipe 12, a magnetic field 16 formed by magnetic line of force 12a of concentric circle is supplied in accordance with the alternating current signal generates. A detection coil 17 for detecting the magnetic field 16 on the ground 11 is covered with a cylindrical magnetic shield 20. Thus, the magnetic line of force 14a generated around the cable 14 and the like cannot easily invade inside the detection coil 17 due to the magnetic shield 20. As the detection coil 17 detects only the magnetic field 16 from the gas pipe 12 and so exact buried position can be surveyed.

Filed: 1988-01-08
Abstract: PURPOSE:To increase the gain of a load FET by connecting a low potential side of a level shift diode to a gate of a field effect transistor FET for load. CONSTITUTION:A gate of a load FET 4 is not connected to its own source but connected to a low potential side of a level shift diode 7 via a signal line 20. Since the drain output of a switching FET 3 is given to a gate of a source follower FET 5, the potential at a constant potential side of the level shift diode 7 changes in following to the drain output of the switching FET 3, a gate bias Vgs of the load FET 4 takes a constant negative value irrespective of the change in the input signal. Thus, the load FET 4 is utilized at a region with a small drain conductance gd and the gain is increased.
