Title: Displacement speed control circuit for nip roller in sheet material conveyer
Inventor: SHIYOUJI TAKASHI
IPC: B65H7/02
Filed: 1991-09-20
Abstract: PURPOSE:To provide a displacement speed control circuit for a nip roller in a sheet material conveyer wherein vibration of a sheet material due to a shock in the case of the nip roller coming into contact with the sheet material, when the nip roller is displaced directed to a main roller for holding the sheet material, can be suppressed. CONSTITUTION:A control circuit 59 for controlling displacement speed of a nip roller comprises divider circuits 98, 100, multiplexer 102, switching signal generating circuit 104, counter circuit 106, D/A converter circuit 108 and a driver 110. When a value of showing a displacement amount of the nip roller, detected by a strain gage 78, reaches a preset value, the multiplexer 102 is switched to the divider circuit 100 of dividing ratio smaller than the divider circuit 98 by a switching signal output from the switching signal generating circuit 104. Accordingly, the control circuit 59 controls the displacement speed of the nip roller based on a frequency of two different kinds.

Title: Water discharge device
Inventor: HONDA TADAHIRO
IPC: F16K21/16
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To prevent breakage by connecting a faucet body that is fixed to a base and the base portion of a water discharge pipe through a torque limitter and specifying torque. SOLUTION: An automatic faucet A is formed by providing a faucet body 11 on a counter 10 having a wash basin B and connecting the base portion of a goose-neck discharge pipe 12 to the top of the body 11. On such an occasion, the base of the water discharge pipe 12 and the top of the faucet body 11 are connected through a torque limiter 40 and the permissible torque of the torque limiter 40 is set at 50 to 150 kg.cm. If the water discharge pipe 12 is turned by accident, considerable torque is applied to the water discharge pipe 12. However, if the torque of the torque limiter 40 exceeds the permissible value, the water discharge pipe 12 rotates relatively to the body 11, and thereby prevents the torque from being transmitted to the body, thereby reliably protecting the faucet body and hand sensor arranged inside from breakage.

Abstract: PROBLEM TO BE SOLVED: To reduce the higher harmonic content of a current by improving the power factor of a power source by providing a step-down chopper circuit between a smoothing capacitor and an inverter and changing the voltage impressed upon the inverter by controlling the step-down chopper circuit independently from a boosting chopper circuit. SOLUTION: A boosting chopper circuit (active converter) 24 is composed of a switching element 8 which is shortcircuited through a DC smoothing series reactor 3 on the output side of a rectifier 2 and a current is converted into an arbitrary direct current by means of a switching element 26, a diode 27, a reactor 28, and a smoothing capacitor 29 constituting a step-down chopper. A microcomputer 15 which is in an initial state turns on the switching element 26 for step-down chopper and a motor 14 is driven by PWM-controlling the ON/OFF duty factor of an inverter 13 in accordance with a rotating speed command 32 from the outside.  The voltage fluctuation of a motor 14 in a chopper period is eliminated by controlling the rotating speed of the motor 14 by changing a DC voltage in a state where the duty factor of the inverter 13 is 100% by turning on/off the switching element 26 through a drive circuit 30 for step-down chopper.

Title: Surface coated cemented carbide die having excellent wear resistance
Inventor: KATAYAMA AKIRA
IPC: B21C3/02
Filed: 1990-09-14
Abstract: PURPOSE:To remarkably improve wear resistance of a die by giving fine cracks on the coated film of a specific thickness fomed on the surface of a tungsten carbide base cemented carbide by chemical vaporized deposit method. CONSTITUTION:Coating film formation is performed by chemical vaporized deposit method (CVD). The coating film is laminated layers of one or more-kinds selected among TiC, TiN, Ti(C, N), Al2O3. Thickness of the coating film is in a range of 2-8mum in order to prevent the wear caused by coagulation. In order to release the residual stress in the coating film, average value of fine crack depth for restraining microscopic breakage is made to be not less than the coated film thickness nor more than the coated film thickness +5mum in the vertical direction from the coated film surface. Average value of the crack width has also to be <=1mum. The reason is that the wear caused by the coagulation becomes remarkably large in the case of forming the crack width to large. Further, average value of the crack interval is made to be >=5mum and <=50mum.

IPC: B24B1/00
Filed: 1986-10-13
Abstract: PURPOSE:To enable the use of a part as the material of a high-speed rotary part by coating the surface of a member composed of carbon/carbon composite with a surface forming material having high hardness, whose elastic coefficient and coefficient of linear expansion is substantially equal to those of carbon/ carbon composite, through an intermediate material. CONSTITUTION:An intermediate material 2 is formed by coating the surface of a spindle material 1 composed of carbon/carbon composite material with plasma flame spraying or the like, while a surface forming material 3 is coated on the intermediate material 2 by a similar method. As the surface forming material 3, a material whose elastic coefficient and coefficient of linear expansion is substantially equal to those of the carbon/carbon composite material and which has a high hardness is used. The surface is thereafter finished such that it has a desired shape and smoothness. In a spindle using carbon/carbon composite, deformation is quite small even under cutting resistance or centrifugal force, or other external forces, and thermal deformation is also reduced, and it can be thus be used as a high-speed rotary part.

Title: Output buffer control circuit
Inventor: NISHITANI KAZUHARU
IPC: H03K19/00
Filed: 1987-09-28
Abstract: PURPOSE:To send earlier as a required signal change than other change and to reduce a through-current of an output buffer by giving a difference to delay value of a delay circuit of an output buffer control circuit depending on a change in the input signal. CONSTITUTION:A signal fed to an input signal connection terminal 20 is delayed by a delay of inverters 5, 6 mainly and fed to p-channel transistor(TR) 1 and an n-channel TR 2 forming an output buffer. In this case, when the input changes from H to L, since the delay of the inverters 5, 6 is small, the conduction of the n-channel TR 2 of the output buffer is quickened and the input state is sent to the output earlier when the input changes from L to H. Since the gate potential of the p-channel TR 1 goes earlier to 11 than the gate potential of the n-channel TR going to H, the through-current is suppressed. Thus, the through-current of the output buffer is reduced and the change in one output signal is sent earlier than the other change.

By this method, printing can be performed without generating the clogging of ink and a printing speed can be increased by overlap-printing.

Title: Power failure detection method
Inventor: UMEZAWA KAZUYOSHI
IPC: G01R19/165
Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To detect a momentary power failure or a power failure with a residual voltage at high speed by comparing a difference of data at two sampling times spaced via one cycle of an a.c. voltage with a predetermined power failure judgment level. SOLUTION: A voltage of one phase of a three-phase power system detected by a voltage detector 21 is converted to a digital signal by an A/D converter 22, and sampled with a constant electric angle synchronous with the voltage. The data are sequentially stored in a memory 24. A processor 23 reads out data at the present sampling time and at the same sampling time of one earlier cycle and operates a deviation of the data. If no power failure occurs and a voltage waveform is normal, the deviation is zero. If a power failure takes place in one cycle, the deviation shows a certain value. A suitable power failure judgment level is set beforehand. The presence/absence of a power failure is detected by comparing the deviation with the level.
