Patent JP-S63229442-A (JP)
Title: Electronic flash controller
Inventor: AMANUMA TATSUO
IPC: G03B7/17
Filed: 1987-03-18
Abstract: PURPOSE:To eliminate the need for measuring objective brightness to low brightness even when a high sensitive film is used and to enable proper automatic electronic flash photography with a simple circuit constitution by setting the reference deciding whether or not electronic flash light can be emitted at the time of the use of a low- sensitivity film to a specific exposure value and setting the reference deciding whether or not the electronic flash light can be emitted at the time of the use of the high- sensitivity film to a specified objective brightness value. CONSTITUTION:The references deciding whether or not the electronic flash light is emitted are switched according to film sensitivity and the objective brightness for the high-density film or exposure arithmetic value for the low-sensitivity film is used as the reference. Namely, the reference deciding whether or not the electronic flash light can be emitted at the time of the use of the low-sensitivity film is set to the specific exposure value and the reference deciding whether or not the electronic flash light can be emitted at the time of the use of the high-sensitivity film is set to the specified objective brightness value. Consequently, the objective brightness need not be measured to low brightness and a measurement time is not prolonged and accuracy is never deteriorated.

Title: Grain oriented silicon steel sheet excellent in magnetic property
Inventor: ISHIDA MASAYOSHI
IPC: H01F1/147
Filed: 1994-03-31
Abstract: PURPOSE:To produce a grain oriented silicon steel sheet free from deterioration in core loss after stress relief annealing and reduced in core loss by arranging many linear grooves in the surface of a steel sheet. CONSTITUTION:After cold rolling, many linear grooves stretching in a direction intersecting the rolling direction of a steel sheet is arranged in the surface of the steel sheet. At this time, it is desirable that at least one of the side walls constituting each linear grooves consists of a plane inclined toward the groove bottom side with respect to the plane perpendicular to the surface of the steel sheet and its angle of inclination is also regulated to 5-60 deg.. It is preferable that the linear grooves have 30-300mum bottom width and 10-70mum depth and stretch in the direction at <=30 deg. angle of inclination with respect to the axis orthogonal to rolling direction and are disposed at 1-30mm spacing in the rolling direction. By this method, the grain oriented silicon steel sheet, minimal in deterioration in magnetic properties even after stress relief annealing in particular and suitable for transformer iron core, can be obtained.

Filed: 1992-03-19
Abstract: PURPOSE:To obtain an inorganic foam containing a bulky and stable aluminum component as an essential component by dehydrating a mixture of a neutralized foamy substance of a water-soluble basic aluminum compound or a water-soluble aluminum neutral salt with a foaming agent and water. CONSTITUTION:A mixture containing a water-soluble basic aluminum compound or a water-soluble aluminum neutral salt, a foaming agent and water is stirred and foamed.

Title: Semiconductor device and its manufacture
Inventor: ONOZAWA SACHIKO
IPC: H01L21/76
Filed: 1991-03-28
Abstract: PURPOSE:To enhance element isolation capability of a GaAs IC and improve the level of integration. CONSTITUTION:An insulating film 40 provided with windows 42, 44, 46 which expose the substrate part of an element forming region are formed on a P-type GaAs substrate 10. Impurities are implanted into the whole exposed surface of the film 40 with the resist 57 which has been used for patterning the film 40 as a mask, and N-type layers 12, 14, 16 constituting electronic circuit element 18, 20, 22 are formed. Since the impurities are added to the whole surface of the substrate parts exposed from the windows 42, 44, 46, the P-type GaAs is not exposed in each window, and electrodes formed in the windows do not come into contact with the P-type GaAs. Since PN junctions are formed between the N-type layers and the substrate 10, leak currents flowing from electrodes in the windows to the substrate 10 can be eliminated. By using element isolation via PN junctions, the level of integration of GaAs IC can be increased as compared with the conventional general element isolation by using semiinsulative GaAs.

IPC: F02P5/15
Filed: 1982-04-16
Abstract: PURPOSE:To reduce, for example, the tendency toward a sudden change (a vehicle shock) of output torque following the shift of gears, by controlling ignition timing in a way of interlocking with a shift operation in a digital manner during the shift operation, in case of a vehicle fitted with an automatic speed change gear and an ignition timing controller. CONSTITUTION:When a speed change gear is shifted up from the first to second, at that point of the shift operation, ignition timing is made into a lag timing control as far as by a definite crank angle T1 and afterward a fine crank angle T2 is made into an advance timing control at every ignition whereby the engine torque in time of the shifting up operation is intentionally checked, thus reducing a sudden change of the output torque of the speed change gear.

Title: Fixing method for toner image
Inventor: NAGAI MASAO
IPC: G03G15/20
Filed: 1987-03-20
Abstract: PURPOSE:To improve absorption efficiency of IR rays so that a fixing operation is speeded up and to adequately heat a base body so that the welding of a toner is improved and a heat loss is prevented by setting the peak wavelength of the IR rays in a 5+ or -1mu range. CONSTITUTION:The toner 51 have a marked absorption band in an IR part near a 5mu wavelength; in addition, the projected IR rays have a peak in the 5+ or -1mu wavelength range and, therefore, even if the base body 6 is constituted of a non-heat resistant material such as paper, the toner 51 on the surface thereof heats up and softens quickly by absorbing the projected IR rays well and are welded to the surface of the paper 6. The surface of the paper 6, on the other hand, to which the toner 51 does not adhere, is inferior in the absorptivity of the far IR rays near the wavelength 5mu to the toner 51 but since said surface slightly absorbs the light of the other wavelength region as well, the surface is adequately heated and improves the fusion of the softened toner 51 but not to the extent of causing the heat loss.

Abstract: PURPOSE:To exactly recognize the luminance distribution of a subject by providing plural photometric means which determine the luminance information of the photometric regions corresponding respectively to plural regions for focus detection thereby discriminating the main subject and exactly measuring the luminance thereof and the background luminance as well. CONSTITUTION:A 1st photometric means obtains the luminance information of the region 1-3 corresponding to the position of the main subject in order to obtain the main subject luminance and the 2nd photometric means obtains the luminance information of the 2nd photometric regions 4, 5 existing around the 1st photometric regions 1-3 in order to obtain the main subject luminance or the background luminance. The 3rd photometric means obtains the luminance information of the 3rd photometric region 6 existing on the outside of the 2nd photometric regions 4, 5 in order to obtain the background luminance. The main subject luminance is thereby always exactly measured even if the position of the main subject and the ratio at which the main subject occupies on the photographing image plane change variously. In addition, the background luminance is exactly measured as well. The conditions of the luminance distribution of the subject are thus exactly recognized.
