Title: Measuring instrument for efficiency of force transmission mechanism
Inventor: TABATA FUMIO
IPC: G01L3/26
Filed: 1984-08-09
Abstract: PURPOSE:To measure efficiency easily and accurately in an actual use state by controlling a driving source and a load means by a control means and taking measurement on the basis of the detected torque of an input/output torque detecting means.

Title: Board processing unit
Inventor: TAKEUCHI NORIYUKI
IPC: B24B47/12
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To detect this when a belt is cut by arranging a belt cut detecting means for detecting a cut of the belt. SOLUTION: When a timing pulley 12-1 rotates by rotating a motor, timing belts 5-1, 5-2 and timing pulleys 12-2, 12-3 rotate by interlocking with it to rotate a rotary body. For example, when the timing belt 5-1 is cut, an idler pulley 13-1 stops, so that a dog 15 does not pass between a phoromicrosensor 16, and a pulse signal is not sent out so as to detect that the timing belt 5-1 is cut. In this case, the timing pulley 12-3 rotates by rotation of the other uncut timing belt 5-2 to transmit torque of a motor to the other rotary body. Thus, a processing object board continuously rotates without impairing rotational torque so much, so that the board is continuously processed.

Title: Automatic focus adjusting device of camera
Inventor: AKATA YASUAKI
IPC: G03B3/00
Filed: 1984-08-09
Abstract: PURPOSE:To prolong the period of focus adjusting operation before film exposure and easily obtain an in-focus photograph by deciding whether a camera is in process of film exposure or not by a decision means and then determining whether a photographic lens is allowed to be driven or not according to the decision making result. CONSTITUTION:A microcomputer MC1 for control, microcomputer MC2 for focus detection and focus adjustment, and further a pull-up resistance for a display part DSP, buffer BF, NOR circuit NO1, etc., are powered on through a line +E connected to a power source battery BA in series. The output of NO1 falls to a level L by the closure of a photometric switch S1 and an interruption signal is inputted to an interruption terminal it of MC1, which starts operating. The decision means decides whether the camera is in process of film exposure or not to determine whether the photographic lens is allowed to be driven or not according to the decision result. Even if shutter releasing operation is performed in an out-of-focus state, the photographic lens continues to be driven until the film exposure is started. Consequently, the focus adjustment period before the film exposure becomes longer than when the focus adjusting operation is inhibited in response to the shutter releasing operation, and the probability that an in-focus photograph is obtained is increased.

IPC: F24C3/10
Filed: 1995-07-03
Abstract: PROBLEM TO BE SOLVED: To obtain a high reliability igniter without casing false electric discharge and without lowering the cost and assembling property by pressing a high tension cable at a lower position than a high tension cable connection part with a downward wall of a tip end of a waterproofing wall. SOLUTION: A waterproofing wall 1d is provided on the upper portion of a high tension cable connection part 6c, and on the tip end of which a downward wall 1f is formed where an end surface A1e is located at a position lower than an output pin. With this construction a high tension cable 6a is pressed downward at its end surface A1e into a U-shaped trap 6b. Accordingly, boiling over soup transmitted along the high tension cable 6a is dropped down at time trap 6b, and it is hindered from entering the high tension connection part 6c. Since an upward wall 1g is formed on the tip end of the waterproofing wall 1d, where an end surface B1h thereof is located at a position above the upper surface of the waterproofing wall 1d, boiling over soup flows to the right and left side surfaces of an igniter body and is prevented from reaching the high tension cable connection part 6c.
