Filed: 1990-02-27
Abstract: PURPOSE:To surely cut a sheet and improve the life of a cutter by elastically regulating the deflection of at least one cutter between a fixed cutter and a driving cutter by an elastic member and generating a uniform sheet cutting force on the whole of the cutter. CONSTITUTION:When a driving cutter 1 revolves, a cutting edge part 1a press-contacts the cutting edge part 3c of a fixed cutter 3, and cuts a sheet inserted between both the cutters. A reinforcing member 5 is installed on the back surface side, in order to support the fixed cutter 3 during this cutting, and the rigidity of the reinforcing member 5 is improved by bending and iron plate into L-figure form, and both the edges are fixed on the supporting plate 2. An elastic member 6 is nipped between the fixed cutter 3 and the reinforcing member 5, and installed at the nearly center part in the longitudinal direction of the fixed cutter 3. Since the fixed cutter 3 is elastically supported so that the deflection of the center part in the longitudinal direction is regulated by the reinforcing member 5 and the elastic member 6, the deterioration of the cutting force at the center part in the longitudinal direction is prevented. Further, each press-contact force of both the cutters 1 and 3 is made uniform, and the sheet can be cut surely according to the recording of a recording device.

Title: Video transmitter and its method
Inventor: SUDA HIROSHI
IPC: H04J13/16
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To maintain a nearly constant frame rate independently of a state of a power supply. SOLUTION: When an output voltage of a battery 30 exceeds a 1st threshold TH1, a transmission control circuit 26 reduces a video compression rate of a video compression circuit 14 and sets '8' to a code division multiplicity (k) for spread spectrum transmission to increase a transmission gain. When the output voltage of the battery 30 is less than the threshold TH1 and equal to or more than a threshold TH2 (<TH1), the transmission control circuit 26 sets a value nearly equal to a medium value to the video compression rate, sets '4' to the code division multiplicity (k) and sets a value nearly equal to a medium value to the transmission gain. When the output voltage of the battery 30 is less than the threshold TH2, the transmission control circuit 26 increases the video compression rate and sets '1' to the code division multiplicity (k) to decrease the transmission gain.

Title: Air to fuel ratio control device
Inventor: YOSHIDA SEIETSU
IPC: F02D41/14
Filed: 1980-04-07
Abstract: PURPOSE: To prevent such engine troubles as engine stall or engine surging by initiating feed-back control from the control value for the air-to-fuel ratio which is the best preferable for transient running state.  
     CONSTITUTION: In the case of a normal running state, output voltage of a throttle 10 is higher one, transistor 154 in the circuit 15 for setting up initial voltage is OFF and the output voltage of comparator 159 is zero volt. When an abrupt deceleration is applied, output voltage of throttle senser 10 becomes lower and the transistor 154 becomes conductive in for a moment. By such an initiation, comparator 159 makes output voltage higher to keep the transistor 154 conductive. At the time, an integral circuit 12 is charged with flow-in current to make the control value of air-to-fuel ratio down abruptly. The control value of air-to-fuel ratio becomes less than a designated value, and then output voltage of comparator 159 becomes lower. Then, the optimum air-to-fuel ratio control value becomes the starting voltage after the abrupt deceleration, and the feed back operation starts in accordance with the value detected by an O 2  sensor 7.

Title: Cassette transporting mechanism
Inventor: OZAWA KEITAROU
IPC: G11B15/675
Filed: 1989-02-28
Abstract: PURPOSE:To suppress the protrusion of a cassette from an insertion opening at an appropriate degree when the cassette is ejected by stopping a cassette holder (CH) by detecting the fact that the CH arrives at a specific position on a moving path, and moving the CH from which the cassette is drawn out to a position to be inserted. CONSTITUTION:When a small cassette (CA) 2 is placed on the CH 4 by pushing it in the direction of arrow head F, a sensor arm 31 is turned in a counterclockwise direction, and a photosensor 33 is set at a light shielding state, and a motor 36 is rotated in the direction of arrow head, and the CA 2 is carried by moving the CH 4 in the direction of arrow head E, simultaneously, sensor arms 20 and 21 are turned in a clockwise direction, then, photosensor 24 and 25 are set at the light shielding states. When the CH 4 is moved in a horizontal direction and lowered vertically, the pin 9 of the CH 4 makes a sensor arm 22 turn in the counterclockwise direction, and a photosensor 26 is set at a non-light shielding state, and the motor 36 is stopped, and the CA 2 is positioned at a loading position. Next, when the CA is ejected, the motor 36 is rotated in a backward direction, and after the CH 4 is vertically raised and moved in the horizontal direction to a cassette insertion opening 38, the motor 36 is stopped.

Title: Output converter
Inventor: MATSUURA TETSUO
IPC: F16H47/08
Filed: 1982-03-20
Abstract: PURPOSE:To reduce the size and weight of an equipment, by making up an auxiliary gear transmission of a planet gear unit including an external gear, to provide the transmission along with a torque converter. CONSTITUTION:An input is applied to a pump 22 and an input shaft 1. When load is high, a turbine 24 reaches drag torque so that the backward torque of a carrier box 17 and the forward torque of the turbine balance each other. The torque of an input sun gear 6 is transmitted to an output sun gear 7 through a planet gear 8 directly coupled to another planet gear 5. Since the turbine 24 is still stopped, the carrier box 17 connected thereto is also stopped so that a group of gears functions as a speed reducer. When the load is low, the output sun gear 7 is put in a directly coupled state so that reduced-speed rotation or equal-speed rotation is transmitted. When the load does not cause an output shaft 10 to rotate, the planet gear 8 receiving the input turns the carrier box 17 backward and the turbine 24 rotates more slowly than the pump 22 so that a kind of drag torque acts.

Title: X-ray microanalyzer and similar device
Inventor: MAKITA YOSHIO
IPC: G02B21/00
Filed: 1984-03-10
Abstract: PURPOSE:To allow invariably accurate sample position setting with no personal error by converting an image signal into a signal indicating the focus state and controlling a sample lifting unit based on two converted signals. CONSTITUTION:An image signal generated from a camera unit via line scanning is differentiated in a differentiating circuit 22, thus retaining a wave height hn in response to the change of this image signal. When an optical-microscope image projected on the camera unit 19 is in a just-focus state, the wave height of the differentiated signal indicates the highest value (h). The wave height hn via line scanning after the highest wave height has been obtained becomes smaller than (h), thus indicating that the focus point has been passed at that point. Then, a command signal is sent to a drive circuit 24 to return by one step to the sample position where the highest wave height was obtained, and the sample is set correctly at the focus position. Accordingly, invariably correst sample position setting with no personal error can be obtained.

Title: Speed changing device for traveling vehicle
Inventor: NISHIKAWA TAKAO
IPC: F16H63/22
Filed: 1987-02-28
Abstract: PURPOSE:To realize the operations of a 1st lever shaft which actuates >=2 shift forks and a 2nd lever shaft which actuates a single shift fork, by pulling a control lever and also oscillating it in two directions. CONSTITUTION:When a control lever 33 is pulled and moved in the lengthwise direction (c), a coupling lever 38 is oscillated and a 2nd lever shaft 19 is turned. Then the shift fork of a secondary speed changing mechanism is actuated via a shift lever 43. When a 1st lever shaft 18 is oscillated toward (a) while the lever 33 is pushed or pulled, an actuating body 30 oscillates toward the shaft 18. Thus the shaft 18 slides toward its axial direction via an engaging body 31. Then a shift lever 21 engages alternatively with >=2 shift forks of a primary speed changing mechanism. The lever 33 is oscillated in the direction orthogonal to the direction (a) of the shaft 18 while the lever 21 is engaging with a single shift fork. Thus the body 30 oscillates and the shift fork is actuated by the rotation of the shaft 18.
