Title: Facsimile equipment
Inventor: KUSAKA TAMOTSU
IPC: H04N5/335
Filed: 1991-10-29
Abstract: PURPOSE:To reduce correction error by correcting the dispersion of reading devices for the unit of a digital step according to data after A/D conversion in case of reading an original. CONSTITUTION:An image reading part 1 reads a background white image, and an amplification factor is increased for each step by a digital step gain switching part 4 so that data outputted from an A/D conversion part 3 can be approximated to a maximum value. A gain is fixed at a point where the data outputted from the A/D conversion part 3 are most approximated to the maximum value. A value calculated by the above-mentioned processing is used for the amplification factor of an image to be read after this processing. Thus, since the amplification factor can be fixed for the unit of the digital step, the dispersion of the devices can be surely corrected by a simple method.

Filed: 1990-10-23
Abstract: PURPOSE:To prevent formation of unnecessary temperature gradient in a temperature measuring resistor and enable stable detection of flow speed by placing a resistor pattern of a heat-generating part symmetrically with respect to a center line perpendicular to its lengthwise direction. CONSTITUTION:A diaphragm part 3a is formed via a gap 2 with respect to a semiconductor substrate, while a heater element 4 is formed at the center and temperature measuring elements 5, 6 independent from each other are formed on both sides respectively.

IPC: H04B7/26
Filed: 1989-10-31
Abstract: PURPOSE:To make the receiver small and to reduce the cost by reading a content of a memory storing English routine sentences and displaying an English routine sentence onto a numerical display means. CONSTITUTION:A paging radio wave is amplified and demodulated by a reception section 102, waveform-shaped and sent to a decoder 103. The decoder 103 checks a call by comparing a receiver reception address data written in a ROM 104 with a received paging signal and after the call is confirmed, the decoder 103 sends a display data in succession to a pager address to a microprocessor 105. The microprocessor 105 corrects an error of the display data, reads alphanumerical display information corresponding to a reception display information code from a ROM 105a in the microprocessor 105 when the reception address designates a specific routine sentence display and outputs an alphanumeric display data to an LCD 106. Thus, the receiver is made small in size and the cost is reduced.

Filed: 1990-10-22
Abstract: PURPOSE:To stably control an optical output of a semiconductor laser at a high speed accurately in high resolution through simple regulation by setting the optical output of the laser to a desired value by gain regulation of a gain converter, and automatically setting a crossing frequency in an open loop of an optoelectric negative feedback loop to a desired value. CONSTITUTION:When a light emitting level comand signal current is I0, if a current attenuation coefficient (i) in a variable attenuator 9 is so regulated that an optical output of a semiconductor laser 1 becomes a desired value P0, a crossing frequency f0 of an optoelectric negative feedback loop automatically becomes a desired value. Even if a coupling coefficient alpha of a photodetector 2 to the laser 1, a received light radiation sensitivity S of the photodetector 2 are varied, when the attenuation coefficient (k) of the attenuator 9 is so regulated as to obtain a desired optical output P0 to a predetermined light emitting level command signal current I0, k.alpha.S = constant is obtained, and hence the crossing frequency f0 of the loop can be automatically set to a desired value.

Abstract: PROBLEM TO BE SOLVED: To estimate a temperature control condition set before a power failure, resume an operation under this condition and require no resetting of cooling temperature by checking inside temperature immediately after turning on a power by a temperature sensor, and setting the cooling temperature of a refrigerator based on the temperature. SOLUTION: The inside temperature Tr of a refrigerating chamber and outside temperature Te are checked (S11) and they are compared (S12) go that it is decided whether a power is turned on due to a temporary power failure or not. When it is decided that a power turning-on state is because of the temporary power failure, the inside temperature Tr is compared with the temperature of each level of an operation display panel to estimate a previous temperature condition by a user. Cooling temperature is set to temperature slightly lower than the compared result by considering a case that the inside temperature Tr reaches temperature slightly higher than setting temperature before the power failure during the temporary power failure (S14, S16, S18, S19).
