Title: Picture signal reader
Inventor: HIKICHI HIROBUMI
IPC: H04N1/40
Filed: 1983-06-30
Abstract: PURPOSE:To correct shading distortion with simple constitution by attenuating an output of an image sensor corresponding to a shading correcting value. CONSTITUTION:The level of a picture signal outputted from an amplifier 5 is decreased at both edges of a one-line picture signal because of the shading distortion. On the other hand, frequency dividing outputs A2, A1 and A0 dividing the one-line pucture signal into 8 are outputted from a counter 2-1. The frequency-divided output is changed in synchronizing with each block divided into 8 and a storage data of an ROM4 is read sequentially from this frequency dividing output. Analog switches 6-6-6-9 are on/off-controlled in response to the read storage data, resulting that resistors 6-1-6-4 constituting a variable attenuator 6 are selected and a picture signal of each block is attenuated with the attenuation in response to the shading correcting value.

As a result, a DC converter 2 is energized, and an AC is generated at the output coils N2-N7 of an inverter transformer T1. The AC generated at the coil N6 is converted by a diode D2 and a condenser C3 into a DC. This DC holds the transistor Q1 in conductive state. Then, the duty of the transistor Q1 is controlled so that the current of a fluorescent lamp is always equalized to the set value.

Abstract: PURPOSE:To manufacture an Al-alloy rolled sheet excellent in formability as well as in strength, by applying, under specific conditions, heating, holding, and cooling to a rolled sheet of Al-Mg-Si alloy after subjected to straightening treatment for the strain caused at the time of solution heat treatment and hardening. CONSTITUTION:The hot-rolled plate or continuously-cast slab of the Al-Mg-Si alloy containing 0.1-1.2wt% Mg and 0.4-2.5wt% Si as essential alloy contents is further cold-rolled to be formed into a sheet, which is subjected to solution heat treatment at 450-600 deg.C and then rapidly to water quenching. Since the Al-alloy sheet warps by the above treatments and, as a result, deformation such as waviness, torsion, etc., that is, strain occurs and the degree of flatness of sheet is deteriorated, the Al-alloy sheet is subjected to straightening treatment consisting of slight skin pass rolling so as to improve the degree of flatness. At this time, formability is deteriorated by the above rolling, so that Al sheet is heated up to 60-360 deg.C at a heating rate within the shaded region in the Fig 1, held for a period within the shaded region in the Fig 2, and then cooled at a cooling rate within the shaded region in the Fig 1. In this way, the Al-alloy sheet excellent in flatness characteristic, strength, and formability can be manufactured.

Abstract: PURPOSE: To make substantially constant the output current irrespective of the pulsating of the input voltage by controlling the series transistor by the transistor which is turned ON through more than a predetermined value of the pulsating voltage.

Therefore, the transistor 10 is apt to be turned OFF, causing the charging current of the battery 11 to be substantially constant. Thus, in order to obtain the constant current from the pulsating voltage, even if the pulsating voltage is changed, it  may be made a constant current.
