Title: Timing belt and manufacturing method thereof
Inventor: FURUSAWA HIRONOBU
IPC: B29D29/00
Filed: 1979-04-27
Abstract: PURPOSE: To improve tensile strength and prevent elongation during using a belt by by elongating the concaved part of the uneven part which is formed on one side of an endless belt made of thermoplastic resin and keeping the convex part unelongated.  
     CONSTITUTION: On the back surface of a timing belt A, the concaved part 1 and the convex part 2 are formed alternately, keeping a fixed pitch intervals, and due to the linkage of the uneven parts 1b and 2b formed on the outer peripheral surface of a belt wheel B, with the uneven parts 1 and 2, the belt A is revolved endlessly. The thin body part 3 which forms the concaved part 1 of the belt A is particle- orientated in the peripheral direction due to elongation, and the thick body part which forms the convex part 2 is kept unelongated. In this case, the tesile modulus of thermoplastic resin is set at 500W2,000kg/cm 2 , and the factor in elongation of the convex part 1 is 1.2 or more, desirably 3W10.

Title: Mode setting device for printer or the like
Inventor: MARUO FUMITAKA
IPC: B41J29/38
Filed: 1990-03-06
Abstract: PURPOSE:To obviate a troublesome key operation and set a mode in a relatively simple manner by a method wherein selection count values with which items of high frequency of change can be discriminated from the other set items are stored in a nonvolatile memory to provide a learning function. CONSTITUTION:For setting a mode, an on-line key 3-6 on an operation display panel 3 is depressed to turn to an off-line, and a mode key 3-2 is depressed. With the repeated use of a mode setting, selection count values 52 in a nonvolatile memory are varied per item of a selection content 51. When a mode is set at this time, the mode key 3-2 is firstly depressed, and the largest selection count value is retrieved in items of a first hierarchy 41. If the two or more same values exist, the determined items are indicated on a character display 3-1 in the order of factory default values. When a next item is displayed by depressing a rightward arrow key, an item of the same selection count value as the present item but a lower order or an item of a fewer selection count value is selected and determined, and the item is displayed on the character display.

IPC: H04N1/00
Filed: 1989-03-07
Abstract: PURPOSE:To recover recording paper without missing it by storing successively the recording paper on which the picture is recorded at every prescribed processing unit by using plural trays based on the order of prescribed priority with a controlling means. CONSTITUTION:A CPU 17 decides whether there is any tray on which the recording paper 10 is placed or not among the trays 5 to 8. At this time, if there are vacant trays among trays 5 to 8, the tray at the upmost step among them is matched with the discharging position of a discharging roller 9. Next, the original picture of one page is received by a communication control part C, and recorded and outputted by a picture recording part P. The recorded recording paper 10 is discharged on the tray 5 to 8 matched with the discharging position of the discharging roller 9 of the picture recording part P. Namely, at every picture communication, the recording paper 10 of one communication portion is successively discharged from the upmost tray among the vacant trays 5 to 8. Thus, the recording paper 10 can be recovered without executing assorting work in which the recording paper is apt to be missed.

Filed: 1989-03-07
Abstract: PURPOSE:To facilitate fixing work by preventing contact of a disc with a fixing board and an actuator when the disc side of the fixing board is engaged with the side wall at a recessed section. CONSTITUTION:A fixing board provided with an actuator driving mechanism 4 for moving a magnetic head 2 in the radial direction of a magnetic disc 1 and supporting an actuator fixed with the head 2 rotatably is provided and a recess is formed at a position corresponding to the fixing board. Under a condition where the actuator is engaged with a stopper 55 at the outermost circumferential side, the rotary shaft section of the actuator is fitted in the positioning section of a base plate 6 and the disc 1 side of the fixing board is engaged with the side wall of the recess. It is arranged such that the disc 1 is not in contact with the fixing board nor the actuator at this time. Since the actuator does not contact with the disc 1 when the actuator is incorporated, the disc can be incorporated easily without damaging the disc.

Title: Method of controlling operation of multinozzle pelton wheel
Inventor: IWAKAWA MITSUO
IPC: F03B15/20
Filed: 1984-03-19
Abstract: PURPOSE:To quickly and surely control the operation condition of a water wheel, when suspension of load-supply to a generator directly connected to the water wheel should occur, by simultaneously closing deflectors of every nozzle, now all opened, together with closing in advance the specified ones of all the needles. CONSTITUTION:When load-supply to a generated directly connected to a water wheel is suspended, each deflector 7a-7d installed on each nozzle pipe 4a-4d is controlled so as to be closed simultaneously at first, thereby suspending the water flow directing to a bucket 3. At the same time, only a specified needle valve 5a out of needle valves 5a-5d is closed. And the remaining needle valves 5b-5d are not closed until predetermined time has elapsed after the load-suspension and moreover until the opening of the specified needle valve 5a has been lowered to the predetermined value. With this contrivance, pressure in a water pressure steel tube 8 never goes up abnormally even if the needle valves 5a-5d are quickly closed. In addition, since the range of small opening for the needle valves 5a-5b can be passed quickly, cavitation can be prevented as well.

Abstract: PURPOSE:To make the operation of a delivery valve smooth by closing an opening end toward the inside of enclosed vessel in the valve chamber of the delivery valve by a rotary member fitted to the lower end of a rotor just before the delivery valve opens. CONSTITUTION:A rotary member 20 is fitted to the lower end of a rotor 17 under a stacked condition together with a balance weight 18. The rotary member 20 is provided to close an opening end toward the inside of enclosed vessel 13 of a cylindrical valve chamber 9 just before a delivery valve 7 fitted inside begins to open. The turning movement of the rotary member 20 opens the valve chamber 9 and the turning movement conducts the operation of carrying cooling medium gas out of the inside of the valve chamber 9 so that the back pressure of the delivery valve 7 may be lower temporarily. Therefore, the opening operation of the delivery valve 7 is smoothly carried out.

Title: Cursor shift device
Inventor: SUGIYAMA HIDETOSHI
IPC: G06F3/0354
Filed: 1984-03-23
Abstract: PURPOSE:To reduce continuously the cursor shift speed in a simple way by securing contact between a conical roller and a rotary ball which is stored rotatably and movably up and down within a housing and reducing continuously the diameter ratio between the roller and the ball with push of the housing. CONSTITUTION:A rotary ball 2 is supported rotatably and movably up and down within a housing 1 which is supported over an operation surface 3 with supporters 1b which can be expanded and contracted. Contact is secured between the ball 2 and the surface 3, and a conical roller 4 is supported rotatably by an arm 5 which is supported rotatably up and down by the housing 1 via a shaft 6. Then the other side of a spring 8 set to a rotary end of the arm 5 is fixed to the housing 1, and the signals proportional to the rotational frequencies of the roller 4 are delivered to an output signal line 9 by a switch 7 set to the arm 5. Therefore the contact position between the roller 4 and the ball 2 is moved toward a prt of a large diameter when the housing 1 is pressed down. Thus it is possible to decrease the shift amount to the ball 2 having a fixed rotational frequency.
