Title: Horizontal deflection circuit
Inventor: BANDO TAKAHIRO
IPC: H04N3/27
Filed: 1990-05-21
Abstract: PURPOSE:To always drive a horizontal output transistor under the optimum condition by applying a driving voltage to be applied to the driving transformer of a horizontal driving circuit which drives the horizontal output transistor and inversely proportional to a horizontal deflection frequency in a first period, and applying a constant voltage in a second period. CONSTITUTION:A timing pulse generated at a timing circuit 10 is inputted to a transistor Q2, which turns on the transistor Q2 in the second period, and simultaneously, turns on a transistor Q1. Thereby, the voltage of a constant voltage source E is applied to an HDT 5. Meanwhile, since the driving voltage inversely proportional to the horizontal deflection frequency is applied from a regulated power supply 3 in the first period, the driving voltage is applied to the primary winding 5a of the HDT 5. Therefore, the value of IB2 can be kept constant in spite of the horizontal deflection frequency since the pulse width of the timing circuit 10 is set larger a little than storage time. In such a way, it is possible to always keep the driving condition of the horizontal output transistor at the optimum condition.

IPC: F21V17/00
Filed: 1993-05-11
Abstract: PURPOSE:To provide a light distribution pattern of a low beam by the effect of a reflection mirror without dependence on any lens step of a outer lens in light distribution control. CONSTITUTION:Reference curve CRV1, CRV2 are set inside a horizontal plane including an optical axis (x) of a reflection mirror. Using a first reference point F on the optical axis as a light emitting point, the reference curve is divided into regions for diffusion angles formed by reflection light on the reference curve with respect to the optical axis (x). The largest diffusion angles are formed in first regions A1, B1 nearest the optical axis; and the middle diffusion angles, in second regions A2, B2; and almost zero, in third regions A3, B3. The center axis of a light source is set along the optical axis of the reflection mirror, and moreover, the center thereof accords with the first reference point F on the reference curve. Assuming an imaginary rotary paraboloid having a second reference point located on the optical axis of the reflection mirror as a focal point and an imaginary plane, the cross line is specified with respect to the reflection point. The position of the second reference points are designated for each point on the reference curve. The reflection surface is formed as an aggregation of the cross lines specified accordingly. A disposition trend of a projection pattern is determined by position setting of the second reference point with respect to the first reference point.

Abstract: PURPOSE:To provide an electroviscous liq. having excellent stability and electrical response characteristics by mixing an organosilica sol with a non-reactive (modified) silicone oil having a predetermined specific gravity in such proportions that the SiO2 content falls within a particular range. CONSTITUTION:An organosilica sol is mixed with a non-reactive silicone oil (e.g., polydimethylsiloxane) or modified silicone oil (e.g., amino-modified silicone oil) having a specific gravity of 0.9-1.3, thereby producing an electroviscous liq. having an SiO2 content of 5-45wt.%. In order to attain stable and uniform dispersion of SiO2, it is necessary to use a dispersion stabilizer, such as octadecyldimethyl[3-(trimethoxysilyl)propyl]ammonium chloride. The obtd. electroviscous liq. can be used in such a state that it is in direct contact with a rubber-like elastic material, because the electroviscous liq. does not contain any oil, solvent or the like which swells or dissolved the rubber-like elastic material.

Title: Control method of motor
Inventor: TAMAKI SATOSHI
IPC: H02P21/36
Filed: 1994-06-15
Abstract: PURPOSE:To control a motor with high efficiency by a method wherein, when a small current reaches a limit value, a speed-torque characteristic and a torque which is output by a current motor speed are operated and a torque instruction value from an accelerator is reduced. CONSTITUTION:The speed torque-torque characteristic of a motor as an object to be controlled is set in advance, and whether a small current is made to flow or not is judged by the present speed of the motor and by a torque instruction value T* from an accelerator. Then, when the current is made to flow, a reduction rate (n) is found, and the magnitude of a small current Id is found by using the found reduction rate (n) so to output. Then, the limit of the small current Id is processed by a speed-torque characteristic which is requested next, and, at this time, the limit of the reduction rate is processed. Then, when the small current reaches a limit value, the limit value of the reduction rate and a torque value Temi which is found by the speed of the motor at this time are output instead of the torque instruction value T* from the accelerator to lower the torque value. As a result, it is possible to control the motor with high efficiency.

IPC: G11B5/71
Filed: 1982-07-30
Abstract: PURPOSE:To enable the expansion in the using range of additives in the case of using a fatty acid ester and a fatty acid having alkyl group as the additives, by using a radiation-sensitive resin as a thermosetting binder. CONSTITUTION:The radiation-sensitive resin refers to such a resin which generates radicals when irradiated with radiations, is cured by cross-linking or polymn. and contains >=1 unsatd. double bonds. If the radiation-sensitive resin is used as a binder, radiation-sensitive resin incroporated in a magnetic coated film is cured by the irradiation of radiations after coating and drying of the magnetic coating contg. said radiation-sensitive resin on a substrate and a calender treatment and before coiling, whereby the coated film during coiling is made stronger. Thus there is no blocking of the additives in the coated film in the stage of coiling said magnetic recording medium and the usable range of the additives is made wider than the case of thermosetting binders in the prior art.
