Abstract: PURPOSE: To prevent a tape from winding round the capstan, by providing the tape sag preventing component on the rotating circumference surface of the capstan.  
     CONSTITUTION: The endless tape 11 coiled around the outer circumference face of a cylindrical ring-shaped fixed reel jumps over the fixed reel from the innermost circumference of the tape coil part to be coiled around the outermost part of the tape through the tape lead-out hole 21 formed to the fixed reel and via the head 23, capstan 24, pinch roller 25 plus the guides 26a and 26b. Then the tape sag preventing component 45 in which the vertical linear part approximates to the rotational circumference surface of the capstan and the approximate space between both directions is set less than a double thickness of the tape is located at the tape send-out side of the capstan 24 and with the width direction set nearly in the radial direction and in approximation to the rotating circumference surface of the capstan 24. In such way, the coiling of the tape 11 around the capstan 24 which is easily caused at the start of the tape travelling can be prevented.

Abstract: PURPOSE:To transmit a control signal through communication channels so that the control signal can be transmitted through another channel even when a channel gets out of order and communications can be performed. CONSTITUTION:When the No. of a called office is selected by keying-in on a keyboard 35, a controller 36 selects a vacant communication channel and sends a control signal to the called office through a control signal sending section (any one of 40, 41, and 42) connected with th vacant channel. At the called office, comparators 37-39 always monitor the communication channels and, when the control signal comes to a vacant chnnel, read the control signal and compare the control signal with the own office No. at the controller. When the control signal coincides with the own office No., the comparators 37-39 output a response signal and connect the vacant channel with a talking circuit 43 by closing one of talking switch sections 40-42. At the calling office the talking switch is closed simultaneously with the confirmation of the response and the talking circuit 43 is connected.

Filed: 1991-06-07
Abstract: PURPOSE:To attain the transmission and reception in a corrected same frequency by eliminating the unmatch of the transmission reception frequency between a caller station and a called station in a TDD radio communication system. CONSTITUTION:A discriminator 20 is provided in a caller station 10 as a frequency correction means and a discriminator 40 is provided in a called station 30 as well. The discriminator 40 calculates a difference  f1 between a transmission frequency f11 from the caller station 10 and a reference frequency f30 in its own station. A CPU 42 controls a sender side local oscillation circuit 45 and a PLL 34 so that a frequency f31 deviated by only a half of the frequency difference  f1 toward the frequency f11 is sent as a correction frequency. The discriminator 20 calculates a difference  f3 between the reference frequency f10 of its own station and the frequency f31. The CPU 22 decides a frequency fc corrected toward the frequency f31 by a half of the frequency difference  f3 to control a PLL 14 and a sender side local oscillation circuit 25. After that, the transmission reception is implemented by using the frequency fc.

Abstract: PURPOSE:To raise engagement strength of a can end plate and a can cover, and also to raise its tightly sealing property by executing wind-clamping by a ring-like chuck to the outside circumferential face of a rolling-in edge part of the can cover, and a rolling roll to the inside circumferential face of said rolling-in edge part, when sealing tightly the can cover to the can end plate. CONSTITUTION:A chuck 9 is fitted to the outside circumferential face of a rolling-in edge part 3a of a can cover 3. Subsequently, when a torque lever 15 is rotated as shown by a virtual line by moving downward a rotary shaft 12, an inside rolling roll 19 is made eccentric by S0 from the shaft center together with a distance of a moving span S of the lever 15, and a roll shaft 17. As a result, the roll 19 is made to press-contact with the inside circumferential face of a rolling-in edge part 3a as shown by the virtual line, and when the shaft 12 is driven to rotate, the roll shaft 17 becomes eccentric through the lever 15 and executes a rotating motion. Accordingly, the roll 19 supported by the shaft 17 rolls along the inside circumferential face of the edge part 3a, the edge part 3a is sealed tightly to an edge part 2a of a can end plate 2, also caulk-working 3b is performed by a projecting line 19a of the roll 19, and it is wind- clamped firmly. In this regard, after wind-clamping is completed, when a rotation of the rotary shaft 12 is stopped, and subsequently, the shaft 12 is drawn up, the roll 19 is returned onto the shaft center again, and a can be detached.

Abstract: PURPOSE:To be able to control NOx stably without prominence of nitrogen oxides in exhaust gas at the load fluctuation time by connecting an exhaust gas supply pipe path with a primary air supply pipe path in such a manner that warming-up of a pulverized coal mill by supply of exhaust gas and start operation of burners by supply of primary air are able to be switched over. CONSTITUTION:At an outlet of an exhaust recirculation fan 21' which recirculates exhaust gas into a furnace bottom of a furnace 1', a booster fan 23' is installed. While a pulverized coal mill 17' is warmed up, mill warming-up is made by opening a gas cut-off damper 26' and controlling gas damper 24' and a cold air damper 13'. After completion of mill warming-up, the mill is started and a coal feeder 16' is also started and at the stage when pulverized coal is introduced into the furnace, damper operation is switched over to operation of a hot air damper 12'. In case when aforesaid method is adopted, even if a signal to add mill load following increased boiler load is transmitted, an excess air ratio is kept in the lower value because of warming-up with exhaust gas.

Title: Four-wheel steering device
Inventor: KISHI MAKOTO
IPC: B62D7/14
Filed: 1989-06-27
Abstract: PURPOSE:To prevent delay of the return steering effectively by stopping supply of the control power to a rear wheel steering means when a set value is stridden down after it is exceeded by the angular velocity in steering given by an angular velocity sensing means. CONSTITUTION:Through a cylinder the front wheels 1 are steered from a steering wheel 10, and a same-phase control valve 98 uses this oil pressure as a pilot pressure and supplies one chamber of a rear power cylinder 90 with the oil pressure of the same-phase steering force. Meantime a controller 126 senses the angular velocity in steering from a signal given by a steering angle sensor 128 and supplies a control signal to an opposite phase control valve 100 on the basis of the result from this sensing and a signal given by a car speed sensor 127 for applying the opposite phase steering force oil pressure to the other chamber of the rear power cylinder 90, and thus the rear wheels 82 are steered with synthetization of the two steering forces. When the angular velocity, which has once exceeded the preset value, strides down the same value, supply of the control signal to the opposite phase control valve 100 is stopped. This prevents delay of the return steering.

IPC: H03D3/00
Filed: 1994-07-15
Abstract: PURPOSE:To obtain a proper balance between a demodulation circuit and a modulation circuit by absorbing a drift due to a temperature change or a power supply fluctuation by applying DC offset to a modulation use operational amplifier every time when transmission is started and to obtain a proper balance between the demodulation circuit and the modulation circuit by absorbing a dispersion due to an instrumental error of a transmitter at all times. CONSTITUTION:While an orthogonal demodulator 115 provides outputs of Q' and I' signals comprising only carriers, a DSP 104 applies a slope voltage from a minimum DC output voltage to a maximum DC output voltage to an input section of modulation operational amplifiers 106, 107 stepwise every time when transmission is started. When comparators 122, 123 detect a OV (a prescribed value) in an output of the modulation operational amplifiers 106, 107, the DSP 104 decides the slope voltage as the DC offset voltage and the operation of the operational amplifiers is started around the DC offset voltage.
