Title: Color mark sensor
Inventor: KANBE YOSHIAKI
IPC: G06K9/38
Filed: 1985-05-27
Abstract: PURPOSE:To set properly both upper and lower reference levels and to discriminate selectively only the mark of a specific color, by using a gate circuit that delivers selectively one of both outputs of a pair of comparators. CONSTITUTION:When a contact 1 or 2 of a changeover switch SW1 is selected, the output of an AND circuit 44 varies in response only to the output of a comparator 41. While the output of the comparator 42 has no relation with the output of the comparator 44. A window comparator 40 works as a comparator having just a single reference value. When a contact 3 or 4 of the switch SW1 is selected, the output terminal of the comparator 42 is connected to the input terminal of the comparator 44. Then the comparator 40 has a normal function. Here a changeover switch SW2 works in response to the switch SW1. When a contact 1 or 3 of the SW2 is selected, the inverted value of the output of the comparator 41 serves as the output of a gate circuit 50. If the contact 2 is selected, the output of the circuit 50 is set at H. Then the output corresponding to the output state of the comparator 42 serves as the gate output when the contact 4 is selected.

Title: Refrigerating plant
Inventor: WATABE MAKOTO
IPC: F16K31/06
Filed: 1989-05-09
Abstract: PURPOSE:To vary capacity of a volume variable type compressor according to a time zone or a schedule by employing a constant-pressure valve as a set pressure variable type constant-pressure valve, and correcting the set pressure of the constant- pressure valve in response to a deviation between the suction pressure of the compressor or temperature of an article to be cooled and the set value. CONSTITUTION:The output of a sensor 38 for detecting the pressure of refrigerant to be sucked into a volume variable type compressor 30 is input to comparing means 41 of a controller 40, and compared with the set value of setting means 42 to calculate a deviation. The deviation is input to set pressure determining means 43 to determine the set pressure. The determined set pressure is output to a set pressure variable type constant-voltage valve 50 through output means 45, and the set pressure is varied. When refrigerating load is excessively larger than the volume of the compressor 30, a solenoid opening/closing valve 39 is opened by a command from the means 45 of the controller 40, and the compressor 30 is operated in the full load. As a result of full-load operation, if the article to be cooled is cooled or the suction pressure reaches its target value, set value or its vicinity, the opening of the valve 50 is thereafter regulated to maintain the suction pressure of the compressor 30 at the set pressure.

Title: Core drawing out device for drawing out take-up core from log
Inventor: KOBAYASHI MASASHI
IPC: B65H19/30
Filed: 1999-04-22
Abstract: PROBLEM TO BE SOLVED: To prevent an outer peripheral surface of a log from wrinkled by compression by drawing out a core from the log in a state that the core is relatively axially moved with respect to the log gripped by a log gripper. SOLUTION: A log gripper 12 grips a comparatively short part near an end of a long log L2, and a length of the log is at least several times as long as that of the log gripper. A log gripping member 18 is moved to a gripping position by an air cylinder 36 to grip an outer surface of the log. When a core C2 is drawn out in this condition, both of the log and the core are displaced right, and the log gripping member 18 is also moved right. On this occasion, as the log gripping member 18 is connected to a link member 22, it is displaced in the radially inward direction of the log L2. Then the gripping force to the log is increased, and the movement of the log is stopped, which enables the core C2 to be drawn out from the log.
