Title: Device for controlling temperature of interior space of showcase
Inventor: FUKUDA TOSHIYUKI
IPC: F25D29/00
Filed: 1988-03-17
Abstract: PURPOSE:To prevent the overcooling of the showcase interior space by dividing the resistor for measuring temperature into one in the air passage and another in the showcase which are serially connected to each other so that when the light is turned off at the close of the business hours, a thermostat may control the cooling rate of a cooling unit. CONSTITUTION:The resistor for measuring temperature is divided into one 10a in the passage 4 and another 10b in the showcase, and the two of them are serially connected to each other. When the light 12 is turned off at the close of the business hours, the resistor 10b ceases to be heated and its resis tance drops, resulting in the reduction of the combined resistance. The resistance of the resistor 10a reaches a point with a corresponding increment where the thermostat 11 goes off. Since the delivered air temperature rises even though the thermostat is not set in two positions, the temperature in the showcase interior space is maintained at the same level as during the business hours.

Title: Method for compiling handwritten character recognizing user dictionary and device therefor
Inventor: SAKAI YOSHIFUMI
IPC: G06K9/62
Filed: 1994-04-01
Abstract: PURPOSE:To create a user dictionary which is adapted to the writing habit of a user and has high character recognizing efficiency when the handwritten characters are recognized after a feature vector is calculated by using the expansion of orthogonal functions of the discrete cosine transform, etc., to an input character pattern and then the feature vector is compared with the key points of both general and user dictionaries. CONSTITUTION:A feature vector is calculated from an input pattern (102), and the distance between the feature vector and an existing representative point calculated (103). Then it is decided whether the calculated distance is smaller than the threshold value alpha or not (105). If smaller, the existing representative point is invalidated (107). Then the calculated feature vector is registered in a user dictionary as a new key point.

Abstract: PURPOSE:To reduce the turning speed of a rotator by making oil pressure horse power coming into a turning motor smaller by providing a discharge amount- reducing means to reduce the discharge amount of a variable capacity pump in connection with the independent operation of the turning motor. CONSTITUTION:A discharge amount reducing means consisting of a flow rate- controlling servo valve 24 to reduce the discharge amount of a variable capacity pump 1 in connection with the independent operation of a turning motor 14 is provided. For example, when a switch valve 5 for turning directions is switched to the upper stage as shown in Fig., pressure oil from the pump 1 flows to a turning circuit to accelerate the motor 14 at a pressure P1. When a torque T1 is reached, the motor is accelerated on a fixed torque line T1-T3 by the action of a pressure compensatory servo valve 20, and when a given rotating condition is reached, a shuttle valve is switched to the lower stage position as shown in Fig. by the difference in pressure between before and behind the throttle 22. Thus, pressure oil from a pilot pump 17 is supplied through the valve 22 to a drive piston 25 and the servo valve 24 is switched to the left position as shown in Fig. As a result, pressure oil in the drive piston 18 flows to a tank and the discharge amount of the pump 1 is set up to a flow rate Q3.
