Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To enable effective use of a retrigerant condensed prior to the stopping of a compressor by providing a first solenoid valve in a tubular channel between a condenser and the compressor and a second solenoid valve in a tubular channel between the condenser and an expansion valve and controlling the opening and closing of each valve by means of the controller. SOLUTION: When operation of an air conditioning device is stopped and thus operation of a compressor 13 is stopped, refrigerant condensed to a high pressure is trapped between a solenoid valve 1 and a solenoid valve 3 when these solenoid valves 1, 3 are closed by means of a controller 15. When re- starting the air conditioning device, the driver or the like turns on a release switch 16 if the duration of the stop is short. By turning on the release switch 16, the solenoid valve 3 is opened and the condensed, high-pressure refrigerant within a condenser 8 or a liquid tank 9 flows through an expansion valve 11 into an evaporator 10. As the liquid refrigerant evaporates within the evaporator 10 at this time, cool air can be supplied to the passenger compartment without waiting for the compressor 13 to start operating.

Title: Recording paper feeder
Inventor: TSUDA SHIGEO
IPC: B65H20/20
Filed: 1987-01-29
Abstract: PURPOSE:To constantly achieve accurate feeding of a recording paper even an error is generated in the positional relationship between a platen and a pin tractor due to temperature variations, vibration or the like, by such an automatic control as to constantly provide a recording paper on a platen with a predetermined slack by use of a photo-detector the output of which is varied according to the distance between the detector and an object to be detected. CONSTITUTION:A positioning mark printed at a predetermined position on an end part of a recording paper is located at a point P1 when the paper is set in close contact with a platen 10 without any slack, and the mark is located at a point P2 when the paper is in a slack state. In this case, the distance from a point M at which a heat generating element 7 of a printing head 1 makes contact with the paper to the point P1 must be equal to the distance from the point M to the point P2. On the other hand, the output voltage characteristic of a photo-detector 5 is represented by a curve having a maximum value when the distance La between the detector and an object to be detected is at a specified value. Therefore, the slack of the paper relative to the platen is automatically controlled to a fixed quantity according to variations in the timing of outputting of a detection signal, and the above- mentioned two distances can be equalized by appropriately setting the characteristics of the photo-detector and the distance K between the photo-detector 5 and the platen 10.

Filed: 1987-01-31
Abstract: PURPOSE:To obtain a luminance signal which agrees with the visual sense characteristic of a human being by deciding the proportion of resolution color component forming the luminance signal in consideration of color mixture caused by the aberration of the color filter spectral characteristic of a solid-state image pickup device from ideal characteristic. CONSTITUTION:Chrominance signals R-B inputted from inputs 62R-62B are inputted to an adder 20 through respective resistors rR-rB and the luminance signal Y is inputted to an output 200 by the adder 20. The resistance values of the resistors rR-rB are pertinently selected in consideration of the color mixture caused by the spectral characteristic of the micro color filter for isolating the color signal disposed on the surface of an image pickup cell array. That means, the respective resistance values are selected to make the proportion of the chrominance signal of the luminance signal Y to be Y= 0.35R + 0.45G + 0.25B. Thus the ideal luminance signal Y which agrees with the visual sense characteristic of the human being can be obtained.

Title: Photodetector
Inventor: TAKAHASHI FUMITAKA
IPC: H01L31/08
Filed: 1986-01-31
Abstract: PURPOSE:To detect a plurality of lights whose wavelength ranges are different from each other by a method wherein a plurality of semiconductor layers which transmit the lights with wavelengths longer than predetermined wavelengths and the predetermined wavelengths of upper layer are shorter than those of lower layers. CONSTITUTION:1st semiconductor layer 1 is formed, for instance, on a GaAs n-type substrate by liquid phase growth of n-type GaAlAs whose ratio between Ga and Al is so controlled as to predetermine a wavelength lambdao1 which is to be a light wavelength limit in a sensitive region by determining a forbidden band width Eg1. Then a P-N junction is formed by diffusing a p-type impurity to display a photovoltaic effect which has a sensitive region in the wavelength range shorter than the predetermined wavelength lambdao1. At that time, the predetermined wavelength lambdao1 can be varied by varying the ratio between Ga and Al, e.g. the forbidden band width Eg1. Moreover, a specific sensitivity for a peak wavelength on the shorter wavelength side can be varied by controlling the depth of the impurity diffusion. In such case, the deeper the depth of the impurity diffusion, the lower the specific sensitivity on the shorter wavelength side.

Abstract: PROBLEM TO BE SOLVED: To record/reproduce data by skipping the flaw position of a disk. SOLUTION: At the time of installing a recording/reproducing disk 1 in a disk player, UTOC information which is read from the UTOC area of the recording/reproducing disk is written in a storage part for UTOC information management 11a so as to store it. At the time of recording, data which is written is read whenever data is written into the disk and it is compared wit write data. When they are not agree with each other, a write part is considered to be a fault part. The address and the size of the fault part are added to UTOC information of the storage part for UTOC information management 11a. At the time of disk injection, UTOC information of the storage part for UTOC information management 11a is written into the UTOC area of the recording/reproducing disk.  At the time of recording, whether the data write position is the fault part or not, is checked by referring to UTOC information. When it is the fault part, the fault part is skipped and data is written.
