IPC: H04B1/04
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a frequency converter that is provided with a variable gain function and an amplifier which are needed to save power of a communication device, etc. SOLUTION: The amplification rate of a buffer circuit 2 is controlled through a control signal from a control circuit 8.

Filed: 1993-07-14
Abstract: PURPOSE:To attain white balance correction without color slurring of a screen by blocking revision inhibition of a gain correction when an image pickup period in an image pickup element is shorter than the change period of a color temperature while the color temperature of a light source is periodically changed. CONSTITUTION:A light source discrimination circuit 62 sequentially monitors a pulse output from a timing pulse generating circuit 61 and outputs an L level control signal P5 to a stability discrimination circuit 80 and a correction value increase/decrease circuit 135 when it is judged that the period is always constant. On the other hand, data relating to an exposure time set by a shutter switch 70 are inputted to a shutter speed discrimination circuit 7 and when the exposure time set by the circuit 71 is less than 1/1000sec, an L level control signal P6 is outputted to the circuits 80, 135. When both of the signals P5, P6 are at an L level, a control signal P4 is always set to an L level in the circuit 80 and fed to the circuit 135 as a white balance operation signal. Thus, revision inhibit of gain correction is blocked and white balance is corrected.

Title: Information signal recording medium reproducing device
Inventor: WATABE YASUAKI
IPC: G11B20/06
Filed: 1984-08-22
Abstract: PURPOSE:To prevent a horizontal synchronizing part from being missed and the resulting horizontal displacement of a reproducing picture by lowering the center frequency of frequency modulation signal for the period corresponding to the horizontal synchronizing part of a composite image signal. CONSTITUTION:A pulse which is kept high level only for the period before and after a leading-edge of a horizontal synchronizing signal of the composite image signal is supplied to a switch circuit S from a pulse generating circuit 9. The switch circuit S is turned on during the high level of the pulse, a capacitor C2 is connected, and the frequency characteristics are lowered. Therefore, if a pseudo- bit (q) exists on a bit at a part of the disc corresponding to the leading-edge part of the horizontal synchronizing signal, the level of the signal corresponding to that pseudo-bit (q) is lowered, which prevents the affect of the pseudo-bit (q).

Title: Manufacture of ceramics part
Inventor: KURASHIMA MAKI
IPC: B24B41/06
Filed: 1986-07-24
Abstract: PURPOSE:To permit the grinding work for a workpiece made of ceramic sintered material free from destruction and improve yield by holding a workpiece by a holder made of elastic material, in closely fitted state, by using a vertical spindle surface grinder. CONSTITUTION:Since the revolving grindstones 5 and 5 always contact the whole of the upper and lower surfaces of a workpiece 1, when the workpiece 1 is surface-grinding-worked, a strong force is always applied onto the workpiece 1, but the workpiece 1 fitted into the holding hole 4 of an outside holder gear 3 is held elastically and firmly free from gap by an elastic holder 2. Therefore, the force applied onto the workpiece 1 is softened by the elastic holder 2, and the workpiece 1 is received by the elastic holder 2, and since transfer is suppressed, the formation of chip and cut on the workpiece 1 is prevented. Therefore, the workpiece 1 can be grinding-worked free from destruction, and the yield can be improved.

Abstract: PURPOSE:To extend the life of a lamp, by decreasing a lamp current when an OCR is parted from a paper and does not read, and increasing the lamp current when the OCR is positioned on the paper and the luminous amount of the lamp is less. CONSTITUTION:A light from a lamp 2 connected to a current V is reflected on a paper 1, the reflected light is received at an image sensor 3 to obtain an electric signal (a) corresponding to a character on the paper 1.

A comparator 7 compares the electric signal (a) with a prescribed value to discriminate whether or not the luminous amount of the lamp is lowered due to aging deterioration, and if lowered, the current of the lamp 2 is increased. Thus, the life of lamp can be extended.
