Title: Bar-code detection circuit
Inventor: RANDARU SUTEIIBUN BATSUTOURIIN
IPC: G06K7/00
Filed: 1993-10-08
Abstract: PURPOSE: To provide a bar code detection circuit easily manufacturable at a low cost capable of accurately reading a bar code without being affected by noise. CONSTITUTION: The slope detector of a wide band width is provided with a comparator 102 provided with first and second time constant circuits connected to first and second input. One time constant is about the triple of the other time constant. The comparator 102 responds to the slope of input analog signals 18 connected to the time constant and changes a state. Feedback is formed by a fixed resistor or a tracking circuit and a smoothing or limiting circuit is used so as to eliminate the noise from the input analog signals. A bar code read system 140 connects first and second limiting circuits 142 and 144 and smooths high and low input signals connected to the slope detector 100b. In order to form symmetrical hysteresis characteristics, the tracking circuit is used.

Title: Recording or reproducing device
Inventor: MAEDA MASAYA
IPC: F16H1/16
Filed: 1986-10-23
Abstract: PURPOSE:To improve the positioning accuracy of a head, by providing a driving means which moves a carriage including a transducer in the radius direction of a medium, and an energizing means. CONSTITUTION:A spring 5 is stretched around two gears in a gear train being interposed between the driving means and the driving source of a head carriage 1 so that its length can be always kept at a constant length for the rotation of the gears. Therefore, a deviating force for eliminating play in engagement is set at constant invariably, and the positioning accuracy of the head carriage 1 can be improved. By setting the deviating force for the driving source such as a motor, etc., so as to set its size in almost equal and a rotational direction oppositely, it is possibly to hold the position of the carriage with a comparatively weak power equivalent to the residual torque of a stepping motor 12, etc., even when the stepping motor 12 is not energized. Also, by stretching the spring 5 for eliminating the play in the engagement between a head carriage driving means such as a cam or a lead screw, etc., and the gear having a reference track position detecting means, the play can be effectively removed. In such way, it is possible to remarkably reduce the position error of the head.

Title: Refrigerator
Inventor: UEMURA MICHIKO
IPC: F25D17/06
Filed: 1991-10-01
Abstract: PURPOSE:To reduce deterioration in quality of food stored in a refrigerator by a method wherein a plurality of cases having upper opened parts are installed in a freezing chamber, and a part of the openings of these cases is provided with a plurality of temperature sensing means for sensing a temperature of the freezing chamber. CONSTITUTION:When a temperature of the first temperature sensor 34a in a freezing chamber is increased up to a predetermined value (t1) deg.C, operations of a compressor and a blower are started. When the temperature is cooled down to a predetermined value (t2 deg.C, the operations of the compressor and the blower are stopped. This intermittent operation is repeated. Then, the freezing chamber is cooled to its predetermined temperature and kept at its value. Since the freezing chamber has a plurality of cases there, a flowing-out of cold air and flowing-in of hot air at the time of opening or closing the door are restricted. An entire temperature increase of the refrigerator as well as a local increase of temperature can be detected fast by a plurality of temperature sensing means 34a, 34b and 34c placed adjacent to the opening of each of the cases. In addition, when the temperature is more than a predetermined temperature, the cold air is continuously fed until the temperature returns to its predetermined temperature so as to restrict an increase in temperature.

Title: Accumulator
Inventor: YAMADA SADAYUKI
IPC: F25B43/02
Filed: 1991-10-01
Abstract: PURPOSE:To prevent oil in a compressor from being short, further lubrication from being inferior and a sliding part from being damaged by a method wherein a plurality of oil returning holes are arranged at a lower part of a partition plate and a plurality of larger oil returning holes than the former holes are arranged at an upper part of the partition plate. CONSTITUTION:In the case that an evaporator has a poor capability and also has a liquid-back state, liquid refrigerant 6 is gradually accumulated within an accumulator. Since a partition plate 4 is fixed within the accumulator, liquid at an upper part of the accumulator is relatively still, 1 and oil returned back from within a freezing cycle together with the liquid refrigerant is divided into two layers at an upper layer 7 of the refrigerant and accumulated there. At this time, the liquid refrigerant accumulated at the lower part is adjusted from the small oil returning holes 5 at the lower part and gradually returned. Oil accumulated at the upper part is returned from the upper part oil returning holes 9 of slightly large size punched at a higher part than the partition plate. Since oil has a higher viscosity as compared with that of refrigerant, larger holes may assure the returning oil volume. A large amount of liquid refrigerant is not returned back to the compressor by these oil returning holes 5 and 9 without accumulating a large amount of oil in the accumulator.

SOLUTION: Concerning this electronic watermark embedding device, when data are inputted from respective input parts, an area dividing part 107 divides the vector data into unit areas for the unit of embedding processing. Next, an apex coordinate retrieving part 104 retrieves the apex coordinates included in the area divided by the area dividing part 107 and judges the number of apexes on the retrieved apex coordinates. The apex coordinate retrieving part 104 calculates reference coordinates based on the found apex coordinates and the number of apexes. An electronic watermark embedding part 105 divides the apex coordinates into the reference coordinates and the apex coordinates and embeds electronic watermark information based on the positional relation of these coordinates.

Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To eliminate fear that a valve is totally closed at the time of a small flow rate control of the refrigerant by providing a control means which controls the variation amount of the valve travel at a specified value or lower when the valve travel is at a specified opening degree or less. SOLUTION: A variation amount ΔPLS1 of a super heat control is calculated, and a variation ΔPLS2 to prevent a frequency change and/or an over-contracted state of a compressor from generating is calculated by an interrupt processing, and these are added to calculate a variation amount ΔPLS of a valve travel (201-203). Then, when the present value travel is smaller than a limited travel which is set at a position being considerably larger than an initial travel, the size of the variation amount ΔPLS is limited.  That is, when the variation amount ΔPLS is larger than a limit value ΔPLSMAX which is determined on the opening side of the valve, the variation amount is limited as ΔPLS=ΔPLSMAX, and when it is smaller than a limit value ΔPLSMIN which is determined on the closing side of the valve, the variation amount is limited as ΔPLS=ΔPLSMIN (205). Then, the one to which the variation amount ΔPLS of the present travel is added is made a target opening degree, and a pulse output processing is executed (206, 207).
