Title: Paper transfer control device of recorder
Inventor: SAKAI KIYOHARU
IPC: B41J11/42
Filed: 1987-10-30
Abstract: PURPOSE:To enable paper feed suitable for each after completion of printing to be preliminarily selected, by a method wherein before start of printing, an operator operates a selection means according to whether a printed page is required to be cut off of not just after printing, and selects ether setting of a cutting transfer mode or a continuous printing transfer mode. CONSTITUTION:Since a specific amount 1 exists between a recording means 1 and a cutting means 3, when multi-lines printing is performed, before start of printing, an operator sets a continuous paper P by retreating a cutting part PK of a printing page P1 so as to be positioned side the recording means 1, and a space between the cutting part PK and an expected printing top line G1 is shortened. Then, in the case where a continuous printing transfer mode is set, when a page feed command is inputted by completion of printing or the like a first control means 5 responses and controls a transfer means 2 so as to send the paper P off to a position where the expected printing top line G1 on the next page P2 faces the recording means. Besides, in the case where a cutting transfer mode is set, a second control means responses and sends the paper P off to a position where the expected printing top line G1 on the next page P2 by exceeds the recording means 1 and the page cutting part PK faces the cutting means 3.

Title: Equipment for dual refrigeration
Inventor: UENO AKITOSHI
IPC: F25B47/02
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To reduce the number of times of startup of equipment for dual refrigeration and thereby to improve reliability. SOLUTION: Two refrigerant heat exchangers 11 are provided for a primary- side refrigerating circuit, and the primary-side refrigerating circuit is connected with a first circuit 3A and a second circuit 3B being a secondary-side refrigerant circuit, through the intermediary of these refrigerant heat exchangers 11. A controller 70 conducts prescribed controlling operations. In other words, it limits the number of times of restart to be conducted after an abnormality stop and prevents each refrigerant circuit (20, 3A, 3B) from being started uselessly. On the occasion of reducing cooling capacity, the second circuit 3B is stopped preferentially. When a high pressure of the first circuit 3A is boosted excessively, only the second circuit 3B is stopped.  When only the state of the refrigerant in the second circuit 3B comes off from a normal state, besides, only the second circuit 3B is stopped. These operations being conducted, the operation of the first circuit 3A is made as continuous as possible. As a result, the number of times of startup of the first circuit 3A being operable for defrosting is reduced in particular.

Abstract: PURPOSE:To prevent production of impact noise and fluttering noise during closing of a shutter by a method wherein an air conditioning ventilating fan comprises a curtainform shutter wound around a rotary shaft located in the vicinity of the exhaust passage outlet of a heat exchanger and opening and closing an exhaust air duct and a feed air duct through rotation of the rotary shaft, and a motor for a shutter to rotate the rotary shaft. CONSTITUTION:When a motor 1 is run, in linkage with the motor, a motor 9 for a shutter is run, and the motor 9 for a shutter is disconnected when a shutter 10 is raised to an upper limit. During disconnection, since a rotary shaft 12 is coupled to the motor 9 through a gear, racing is prevented from occurring, the shutter 10 holds this state, and an exhaust air duct A   A' and a feed air duct B   B' are opened. When the motor 1 is brought into a stop, in linkage with the motor, the motor 9 for a shutter is reversed. The motor 9 for a shutter is disconnected and stopped when the shutter is suspended to a lower limit, and the exhaust air duct A   A' and the feed air duct B  B' are closed.

IPC: H02J7/00
Filed: 1992-10-16
Abstract: PURPOSE: To prevent the second discharge of a battery by detaching the battery from load, when voltage supplied by the re-chargeable battery reaches a certain value or less. CONSTITUTION: The gate terminal of a MOSFET 17 is connected at the negative terminal of a re-chargeable battery 11, and the source terminal of the MOSFET 17 is connected at the positive terminal of the re-chargeable batter 11. The MOSFET 17 is connected so as to flow a current through a load 15 from the re-chargeable battery 11 during a time, when the MOSFET 17 is biased in the forward direction. When the voltage of the re-chargeable battery 11 is discharged up to the value of interrupt voltage between the gate and source of the MOSFET 17 or a voltage lower than the value of the interrupt voltage, the MOSFET 17 effectively detaches the re-chargeable battery 11 from a load 15.

Title: Axial-flow fan
Inventor: INAZUMI HIDEYOSHI
IPC: F04D29/38
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To reduce noises that would otherwise be conspicuously noticeable when a flow goes from a positive pressure surface to a negative pressure surface of blades by providing a boss portion and a plurality of blades formed radially on the periphery of the boss portion and by forming a rough surface on the positive pressure surface of each of the blades, starting with the side opposite to the turning direction and extending toward the periphery. SOLUTION: An axial-flow fan of an electric fan comprises a boss portion 1 provided with an insertion hole 2 in which a rotary shaft of a motor is inserted and a plurality of blades 3 that are radially formed on an outer periphery of the boss portion 1. On each of the blades 3, a rough surface 4 is formed, starting with the side opposite to the turning direction and extending toward the periphery. The rough surface 4 is formed so that it occupies the greatest area in a part on the side opposite to the turning direction and on the periphery side, with a taper toward the boss portion 1 on the side opposite to the turning direction and toward the turning direction side on the periphery. When the axial-flow fan is turned, a flow of air that moves along the positive pressure surface of the blade 3 goes toward the side opposite to the turning direction and the periphery side.  The rough surfaces 4, however, cause the air flow to separate, thus damping noise of a specific frequency.

Title: Picture work station
Inventor: TANIGUCHI TADASHI
IPC: G06T1/00
Filed: 1989-10-27
Abstract: PURPOSE:To improve the memory efficiency by thinning the picture data while they are transferred via a multiple pixel bus. CONSTITUTION:A thinning transfer means consists of the thinning transfer controller 8, the data temporary storing latches 9a - 9d, and the switches 10a - 10c. Then the transfer means transfers the picture data to a picture display memory 2 from a picture memory 1 via a multiple pixel bus 3 and at the same time thins the picture data so as to store them in the memory 2. In other words, the memory 1 is not used to thin the picture data and these data are thinned while they are transferred to the memory 2 from the memory 1. Thus the overall transfer time of the picture data is shortened and at the same time the efficiency of the memory 1 is improved.
