Title: Automatic feeder for carbonic acid gas
Inventor: YAMADA SHIYOUICHI
IPC: H02K9/24
Filed: 1979-02-21
Abstract: PURPOSE: To discover a seat leak of the reducing valve early by providing a carbonic acid gas concentration detector, relay and alarm which are operated by a detection signal from said detector to the blow-off pipe of safety valve in the secondary circuit of the reducing valve.  
     CONSTITUTION: Gas leaked in the atmospheric air pipe 10 is detected by the concentration detector 11 and is converted into an electric signal to discover the leak early by means of the alarm 12. Also a unit exclusively used in the actual spot, in which the detector 11 and the relay 13 are incorporated, is installed to perform a visual inspection. Moreover two safety valves can be used in series and the detector can be mounted on the discharge pipe that connects the said valves to each other to detect the leak surely.

Title: Slipping-out preventive anchor pin
Inventor: FUNAKI CHUICHI
IPC: E02D5/80
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To make an anchor pin hard to slip out by forming the taper part having the outer peripheral shape of being gradually diametrically expanded in the upward direction, in plural stages in the main body driving part through a diametrically contracted step difference. SOLUTION: A main body 10 of an anchor pin 1 is formed in a round straight bar shape composed of a hard body by a steel wire rod so that the upper part is integrally molded as an almost L-shaped locking part 11 slightly bent to an acute angle from a right angle. The taper part 14 having an outer peripheral shape of being gradually diametrically expanded in the upward direction is formed in the body part of a main body between the lower end tip part 12 and the locking part 11 so that this taper part 14 is continuously formed in plural stages through a diametrically contracted step difference 15. Therefore, the taper part 14 does not become resistance at driving time since it is squeezed downward, but the step difference surface 15a becomes moving resistance to pulling-out directional force by functioning as the checking surface to the contrary.  Therefore, an anchor pin can be made hard to be pulled since the diametrically contracted step difference of the taper part becomes resistance.

Filed: 1984-02-03
Abstract: PURPOSE:To perform the desired operating pattern with an inverter of low capacity by selecting desired voltage and frequency to control the gate of the inverter when altering the operating pattern. CONSTITUTION:When switching from a low speed to a high speed, a switch S5 is opened, S6 is closed, S1 is opened, S2 is closed, and MS1 is opened. Thus, voltage/frequency ratio pattern converting means 14 is set to a high speed pattern. Further, the integrating function of frequency rising regulating means 12 is inhibited, and switching of the frequency setting means 10 is simultaneously performed. Accordingly, it is instantaneously shifted to high speed side frequency voltage setting. Then, the output voltage of the inverter is throttled to zero. Then, a high speed side switch MS2 is closed to rise the output voltage of the inverter from zero to the optimum pattern.

Title: Torque limiter, sheet feeding device and image processing device
Inventor: KASHIWABARA AKIHIRO
IPC: F16D7/02
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To make the transmission torque variable by transmitting a fixed range of torque by hysteresis torque generated by the relative rotation of a permanent magnet and an opposed magnetic substance and adjusting the opposed area of the permanent magnet and magnetic substance. SOLUTION: In the case of enlarging set torque of a torque limiter, a movable member 44 is rotated in relation to a drum part 42, and the movable member 44 is moved in a direction of an arrow mark D and then fixed by a set machine screw 45. The opposed area of a permanent magnet 41 and a magnetic member 43 is therefore enlarged, and hysteresis torque is increased at the time of starting to get into a slip state so as to increase transmission torque. When the movable member 44 is moved in a direction of an arrow mark E, the opposed area of the permanent magnet 41 and magnetic member 43 becomes small so as to reduce transmission torque. Various kinds of sheets can therefore be separated with appropriate torque transmission by using this torque limiter for a sheet feeding device, so that the sheets can be fed without double feed for image processing.
