Patent JP-H1178037-A (JP)
Title: Recording apparatus
Inventor: ITO CHO
IPC: B41J2/18
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To free the air even in the case of a dye-based and a pigment-based ink, by prying open a part of a contact face between a cap sucking ink inside a suction means and a part of an ink discharge face of an ink-jet head by a lever with the utilization of an elasticity of rubber, and forming an open point to the air. SOLUTION: A cap 17 comes in tight contact with an ink discharge opening of a recording head, whereby ink is sucked. After the suction, a cam 24 rotates by θ1 in a direction of an arrow 33. As a result, a circular conical leading end part 34 of a shaft 32 fixed to a central part of suction caps 17a, 17b is caught by a projecting cam 31 integrally formed with the cam 24. When the cam 24 rotates by θ2, the circular conical leading end part 34 is pulled downward tracing the cam 31. Because of a position within a maximum cam lift amount θ3, the vicinity of the shaft 32 is pulled while the suction caps are pressed to the discharge opening, turning an adhesion part to the discharge opening into an open state to the air. Accordingly, the air enters from an opened part, so that the ink in the caps is removed.

Abstract: PROBLEM TO BE SOLVED: To quickly cope with needs at a construction site by applying the constitution that a foot part and a leader retaining part are connected to each other with bolts projected, an inverse thread is formed on one of the bolts, and respective bolts are screwed to both ends of an adjustment member for connection. SOLUTION: Strip type stainless steel plate or the like is bent to an approximate U-shape so as to suit the external surface of a square leader, thereby forming a retaining part 3 having a front 31, both sides 32 and a back 33. Then, one end of the back 33 is connected to a hinge part 34. Also, a screw 35 is fixed to the central section of the back 33 so as to project toward a wall. Furthermore, an inversely threaded screw 12 is fitted to the central section of a fixed plate 11 kept in contact and secured to the wall, so as to project toward the leader, thereby forming a foot part 1. Thereafter, the foot part 1 is secured to the wall, and one end of an adjustment member 2 is screwed to the inversely threaded screw 12. At the same time, the threaded part 35 of the retaining part 3 is screwed and fixed to the other end of the member 2.  Furthermore, the hinge 34 is opened and closed, thereby securing the leader to the retaining part 3. As a result, needs at a construction site can be quickly met.

Title: Apparatus for measuring angular frequency for body of rotation
Inventor: MAEZAWA KENSHO
IPC: G01P3/489
Filed: 1988-10-03
Abstract: PURPOSE:To enable attainment of high resolution by subjecting the number of samplings per rotation of a rotation body 1 to frequency division, by changing a constant of an integrating means and by making thereby variable the range of an angular frequency to be measured. CONSTITUTION:An angular frequency measuring device 1 measures a pulse from a pulse generator 3 connected to a rotation body 2 and thereby measures an angular velocity omega(t) of the rotary body 2. The pulse of this generator 3 is frequency-divided into 1/N by a frequency divider 4, integrated by an integrator 5 and compared with a prescribed reference value Vr by a comparator 6, and when an output of the integrator 5 exceeds the reference value Vr, a signal is outputted. Then, the output of the comparator 6 and a high-frequency pulse from a high-frequency pulse oscillator 7 are inputted to a gate 8 and the high-frequency pulse is subjected to strobing by the pulse of the comparator 6. An output of the gate 8 is converted into an analog value by a D/A converter 9 and further converted into a reciprocal by a reciprocal converter 11, which is outputted as the angular velocity omega(t).

Then, the torque value applied by the wrench B at the time when the torque is increased to the specified value by the wrench B and made to be free state, is held. With this arrangement, the detected torque value of a detecting means 6 and a measured torque value of the wrench B are compared to decide the normal/defective condition of the device 1. Conse quently, the inspection of working state is made easy without detaching the device from the equipment, etc., thereby the working efficiency is improved.

Title: Illumination standard setting device
Inventor: OTSUKA RIE
IPC: G01J3/10
Filed: 1989-09-26
Abstract: PURPOSE:To calibrate a lighting measuring instrument by directly using the light of an electric discharge lamp by integrating and comparing the output of a standard photodetector which is given a response extent corresponding to the illuminance of the electric discharge lamp with the output of a reference voltage source and controlling the illuminance of the electric discharge lamp. CONSTITUTION:The light of the electric discharge lamp 1 is made incident on the standard photodetector 2, whose output has a ripple removed by an integration circuit 3 and is sent to an analog comparator 5. The comparator 5 compares the output of the circuit 3 with the output of the standard voltage source 4 and outputs a digital signal '1' or '0' according to whether the output of the circuit 3 is larger or smaller. The integration circuit 6 integrates and smoothes the digital signal and inputs the result to a dimming device 7 to form a feedback loop. Consequently, the output of the photodetector 2 is held equal to the set value of the voltage source 4. Therefore, the lighting measuring instrument can be calibrated by directly using the light of the electric discharge lamp and its measurement error is reduced.

Title: Stroboscope circuit
Inventor: HATA KOJI
IPC: H05B41/32
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To stop the charging of a main capacitor by using an inexpensive part. SOLUTION: An oscillation circuit consists of an oscillation transistor 22 and an oscillation transformer 23 and even if a stroboscope charging switch 26 is once turned on and immediately off, operation is continued to keep the charging of the main capacitor 41, by the positive feedback of a transistor for a latch 24. The potential of the junction A of the voltage dividing resistors 36 and 37 of an oscillation stopping circuit 35 becomes lower as the charging voltage of the main capacitor 41 becomes higher. When the main capacitor 41 reaches a prescribed charging voltage, the voltage between the junction A and the fourth temtinal 23d of the oscillation transformer 23 becomes the operating voltage of a stopping transistor 39 or more and the stopping transistor 39 is turned on.  Thus, the oscillation transistor 22 is turned off and according to this fact, the transistor for the latch 24 is tuned off as well so that the oscillation operation of the oscillation transistor 22 is stopped and the charging of the main capacitor 41 is stopped as well.

Filed: 1985-11-08
Abstract: PURPOSE:To move the 1st group lens to an imaging plane side while a camera is not in use and to make the form of the camera compact when the lens is housed therein by providing a moving means which moves the 1st group lens to the imaging plane side from the state in which said lens exists at the end on the side where the spacing between the 1st group lens and the 2nd group lens increases.

The overall length of the lens is thus made shorter. For example, the 1st group lens 1 is further moved toward the imaging plane side up to the position shown by a broken line 1' from the end on the wide angle side when the camera is not in use. The overall length of the lens is thereby made shorter and the entire part of the zoom lens can be housed in approximately the thickness range of the camera body.
