Title: Differential amplifier circuit device
Inventor: SEIKE TADAYOSHI
IPC: H03F3/45
Filed: 1988-12-01
Abstract: PURPOSE:To reduce a noise due to a differential amplifier circuit itself by separating the ground terminal of an output stage part from that of a differential stage part and a level conversion stage part. CONSTITUTION:The ground line of the output stage part 1 is separated from that of the differential stage part 2 and the level comversion stage part 3, and both lines are derived to respective ground terminal separately. Therefore, since the amounts of change of currents i2 and i3 that flow on the differential stage part 2 and the level conversion stage part 3 are so small as to neglect compared with that of the output stage part 1 in the amplification of a small signal, no influence of potential change at a point A is given on the differential stage part 2 that is an input stage. Thus, since no influence of voltage change by the current change of the output stage part 1 is given on the differential stage part that is the input stage, it is possible to remarkably reduce the noise in the amplification of the small signal.

Title: Correcting control device during transition period of electronic fuel injection
Inventor: ARITA HIROSHI
IPC: F02D41/18
Filed: 1994-12-09
Abstract: PURPOSE: To keep a stoichiometric air-fuel ratio even at asynchronous injection by anticipating intake pipe pressure for the calculation of the amount of asynchronous fuel injection by which fuel that is insufficient at synchronous injection is injected during sudden acceleration. CONSTITUTION: In correcting control during the transition period of electronic fuel injection, the same routine is employed in the computation of corrections at both synchronous and asynchronous injection timing, and computation of the corrections is executed (S1, S2); i.e., transient corrections are computed at an interval of 360 deg.CA in the case of synchronous injection, and if there is further variation in the variation of intake pipe pressure as a result of sudden acceleration, asynchronous injection is performed. In this case, the previous and current intake pipe pressures are periodically compared, and if the current intake pipe pressure becomes greater than the previous one by a predetermined amount or more, sudden acceleration is recognized and then asynchronous injection is performed.  The amount of injection in this case is determined through the estimation of intake pipe pressure from variation in the previous intake pipe pressure as in the case of synchronous injection, thus a deviation from a stoichiometric air-fuel ratio is avoided.

A blanking addition circuit 5 varies the brightness level added by blanking based on the mean brightness level outputted from the mean luminance detection circuit 9 to add blanking to the output of a horizontal time compression circuit 4. Thus, the blightness of the blank part at both horizontal edges of the screen is varied in response to the blightness of the part displayed of picture.

Filed: 1991-10-25
Abstract: PURPOSE:To stably travel a tape by forming a frame-shaped pedestal with plural longitudinal frames and horizontal frames, supporting a magnetic head inside of the pedestal and forming a guiding part guiding the magnetic tape to the horizontal frames. CONSTITUTION:The azimuth and the height of a magnetic head combination body 8 are adjusted by adjusting screws 11a and 11b using a projection 10 of the pedestal 1 composing of horizontal frames 2 and 4 and longitudinal frames 3a and 3b.

Title: Cooling tower for cooling mold cooling water
Inventor: MURATA KENTARO
IPC: F28C1/02
Filed: 1997-10-20
Abstract: PROBLEM TO BE SOLVED: To prevent the inclusion of dust into a cooling water from occurring and thereby, enable the positive circulation of the cooling water in a mold by covering an intake vent positioned below the casing of a cooling tower with an air filter made of a fine breathing material. SOLUTION: An intake vent 3 is formed from the lower part of a casing 1, that is, from the lower end part of a filler (an exchanger fin) 6 to an area near the upper part of a water tank 8, and a louver 3a for retaining the shape of an air filter 2 is provided in the intake vent 3. In addition, the air filter 2 of an unwoven fabric is wound around the surface of the louver 3a. The upper/lower edge parts of the air filter 2 are marginally fixed with a frame 3b and are protected with a wire mesh 3c. The material of the air filter 2 to be used is felt, a breathing foam resin sheet or the like in addition to the unwoven fabric. Consequently, almost all of the dust contained in an atmosphere is intercepted by the air filter 2, so that the dust which is likely to block a cooling water circulation passageway in a mold does not find its way into the mold cooling water.

Title: Soft tennis ball
Inventor: ASANO KAZUYOSHI
IPC: A63B41/00
Filed: 1993-12-07
Abstract: PURPOSE:To provide an excellent improved weatherability and provide a soft tennis ball whose surface crack generation is small and which has almost the same striking feeling and forming workability with those of a ball of natural rubber alone, by making the ball out of a rubber formation which contains by a specific rate EPDM whose iodine value is specific in regard to natural rubber. CONSTITUTION:A soft tennis ball is made of a rubber formation which contains by 5-15wt.% EPDM whose iodine value is 10-15 in regard to natural rubber. When the iodine value of the EDPM is less than 10, the effect of crack prevention is small as vulcanization is insufficient, and when it is more than 15, vulcanization progresses too much, and the ball is hardened and the touch becomes rough, and even the feeling of ball-striking becomes affected. When an addition quantity is less than 5wt.%, it has no effect for crack prevention, and when it is more than 15wt.% it is effective against crack prevention, but the feeling of ball-striking becomes heavy with the increase of the addition quantity, and also the adhesiveness of the rubber combination lowers, so joining at the time of forming is not sufficient, and the outer appearance becomes bad, too. At the same time, there is a nonstandardization tendency such as a bound.

Abstract: PURPOSE:To simplify the constitution of an electrostatic discharging device and to effectively converge light on a photosensitive body by arranging light emitting elements with high density only at a necessary part, and also arranging a columnar lens and the light emitting element array so that their axes are parallel to each other. CONSTITUTION:An electrostatic discharging device consists of a substrate 40, light emitting elements 41 arranged on the substrate 40, a frame 43 which has many windows 42 for sectioning the elements 41, and the columnar lens 46 which has ribs 45 axially on both flanks. An original is set on, for example, a registration type copying machine irrelevantly to its size. An area is set with high density nearby both ends in the axial direction of the photosensitive body, which is discharged electrostatically. Consequently, the array density of the elements 41 is made large at both end parts. Further, the elements 41 are arrayed at rough intervals close to one end and at close intervals on the side distant from the other end. Consequently, light from the light emitting element can be converged sufficiently and the cost of the device is reduced.
