Title: Skin color correcting circuit
Inventor: SHIMOYANAGIDA SUSUMU
IPC: H04N9/64
Filed: 1990-08-30
Abstract: PURPOSE:To make the reproduction of a bright white color and the reproduction of a healthy skin color compatible by applying a resistance mixing a B-Y signal and a G-Y signal or a B signal and an R signal prepared in a color signal circuit. CONSTITUTION:Among a Y signal and three color difference signals R-Y, B-Y and G-Y outputted from respective output terminals 4-7 of a color signal circuit 1 and transmitted to respective input terminals 8-11 of a color output circuit 2, the B-Y signal and the G-Y signal are electrically mixed in advance through a resistance 15. By doing like this, since at a display 3 side, the G-Y signal and the R-Y signal are optically mixed, even when setting color temperature equally, the skin color becomes healthy pink color adding a red color to an yellow color. Thus, regardless of the setting of the color temperature, it is possible to reproduce the healthy skin color adding the red color to the yellow color.

Filed: 1994-09-27
Abstract: PURPOSE: To reduce the number of valves, reduce the cost, and miniaturize an anti-skid hydraulic pressure device by providing a pump, which is connected to an outflow valve in parallel and sends a brake fluid to first and second wheel cylinders. CONSTITUTION: First and second inflow valves 9, 10 are communicated with an outflow valve 6, while the brake fluid of respective wheel cylinders 3, 4 is returned to a reservoir 7 via a pipe lines 23, 24, respective inflow valves 9, 10, pipe lines 22, 25, and the outflow valve 6. At this time, although the brake fluid is being discharged from a pump 8, the pressure of respective wheel cylinders 3, 4 is surely is reduced because the speed of the release of the brake fluid within the respective wheel cylinders 3, 4 is faster than the speed of discharge of the brake fluid. The reduction of the wheel pressure like this is carried out when the slip ratio becomes high like in the case of a locked condition of a wheel, thereby urging the recovery of the wheel speed.

Title: Power train controller
Inventor: ONAKA TORU
IPC: B60W10/18
Filed: 1988-09-16
Abstract: PURPOSE:To ensure both the convergence and the stability of the control characteristics of an automobile controller described at the heading by setting the initial control condition according to the preceeding control condition when the current control mode changes to the brake control which is executed by a driving force control or an anti-lock control means. CONSTITUTION:The outputs from a driving force control means D and an anti- lock control means F are sent to a setting means G. When the drive control is changed to that using a driving force control means D or the braking control to that using the anti-lock control means F, setting means G sets an initial control condition according to the preceeding control condition. For example, at the time of change to the driving force control, a throttle gain is reduced to avoid quick increase in output torque according to the friction coefficient estimated by the anti-lock control means F. In such constitution the control precision at the early time of the change may be improved.

CONSTITUTION:The curved face of the primary mirror for converging a ray 6 incident parallel to an axis 3 always at the point D on the axis 3 is expressed by the equations 5, 6, where alpha, r1, r2 are expressed by the equations 1-4. Here a master mold 7 of a convex shape having the curved surface 9 of the primary mirror expressed by the equations 5, 6 is made by numerically controlled working of a metal. A fiber reinforced plastic CFRP8 is coated in laminar superposition as shown by (b) on the mold 7 and the plastic is separated from the mold 7, whereby the CFRP8 of a concave shape having the face 9 shown in (c) is obtd. Aluminum or the like is directly deposited by evaporation on such curved face, and the face is immediately usable as the curved face of the primary mirror.

Title: Magnetic recording medium and its production
Inventor: MATSUOKA SHIGETO
IPC: G11B5/62
Filed: 1985-10-19
Abstract: PURPOSE:To obtain a magnetic recording medium having recording tracks in common use as tracking servo tracks by a simple method by alternately providing thin iron oxide films of magnetic and alpha-hematite to a concentration or spiral shape on a non-magnetic substrate. CONSTITUTION:An Au underlying film 2 is deposited by sputtering or the like to about 0.3mum thickness on the non-magnetic substrate 1 consisting of Si, etc. and while the temp. of the substrate 1 is maintained at 150 deg.C, an alpha-Fe2O4 film 3 having about 0.2mum thickness is first formed by sputtering on the layer 3 by using Fe as a target in a gaseous mixture composed of gaseous Ar and gaseous O2 under 10mTorr. A laser beam adjusted to 15mum width is then irradiated into a stripe shape on the above-mentioned film in an H2 atmosphere to execute heat treatment, by which only the irradiated part is converted to the concentrical thin ferromagnetic Fe3O4 film 3B. The film in which alpha-Fe2O3 and Fe3O4 coexist is subjected to a heat treatment at 330 deg.C in air to convert the film 3B to a thin ferromagnetic gamma-Fe2O film. The part where there is no beam irradiation is made to remain as the alpha-Fe2O3. The surface recording density is thus improved.

Title: Heat exchanger
Inventor: ITABASHI YUKIHIKO
IPC: F28F9/18
Filed: 1982-12-27
Abstract: PURPOSE:To make it possible to shield a welding section of the heat exchanger from the atmosphere by a method wherein in the heat exchanger made of a titanium type material, a tapered section is formed at the outer end of a heat transfer pipe fitting hole and the top end of the heat transfer pipe is positioned in the vicinity of the boundary of the tapered section and the heat transfer pipe fitting hole. CONSTITUTION:The heat transfer pipe fitting hole 4 is drilled through a titanium type pipe plate and the outwardly widened tapered section 11 which is inclined at an angle of about 15-45 deg.C and which has a length of from several to several tens times the thickness of the wall of the heat transfer pipe 1. Then a titanium pipe as the heat transfer pipe is inserted into the fitting hole 4 in such a manner that the top end of the pipe 1 coincides with the boundary of the tapered section and the fitting hole and is welded to the pipe plate 2 as at 3. The welding is performed in such a manner that a torch 6 is made to confront the top end of the pipe 1 and an inert gas retaining area (a) is formed between the pipe and the tapered section 11 so that the welding section is completely shielded from the atmosphere to thereby prevent pollution due to an activated gas. Further, the tapered section 11 is made bell-mouthed so that no vortex of the cooling water generates when the cooling water enters the heat transfer pipe and the adhesion of organisms to the surface of the pipe plate is prevented.

Abstract: PURPOSE:To perform a stable operation with a simple circuit by switching two sets of drive transistors by counterelectromotive voltages generated in 3-phase coils and a position signal obtained from the drive current of a motor, thereby sequentially energizing the 3-phase coils. CONSTITUTION:3-Phase ACs are generated by two sets of drive transistors 4a-4c, 5a-5c by a DC power source 1, supplied to coils 3a-3c, and a rotor 2 is rotated without brush. Counterelectromotive forces Va-Vc generated at terminals A-C at that time and a signal K amplified by an amplifier 16 from a DC load current are input to a position detector 11. The detector 11 calculate the signals Va-Vc and K, and outputs control signals D1-D3. A selection converter 14 selects signals L1-L3 of a start accelerator 13 at starting time, but sequentially switches to energize drive transistors 4a and 5a, 4b and 5b, 4c and 5c by the signals D1-D3 at normal operation time, and regulates the energizing time. Thus, a stable operation is performed with a simple structure. This is adapted for a compressor.
