Title: Phase synchronizing type external light system electric shutter corrected by change in internal light
Inventor: NOBUSAWA TSUKUMO
IPC: G03B7/093
Filed: 1979-03-02
Abstract: PURPOSE: To enable the shutter time equivalent to that of an internal light system while it is of an external light system to be obtained by performing required correction based on the results of the comparison of the error DC voltage based on the external light response signal and the error DC voltage based on the internal light response signal.  
     CONSTITUTION: An external light response signal generator 1 and an internal light light response signal generator 2 emits signals respectively at the frequencies fa or Fb corresponding to the intensity of the external light or internal light. The amplifiers 33, 73 of a PLL circuit 3 or 7 generate error DC voltages Vd 1 , Vd 2 , and voltage control oscillators 34, 73 generate the signals of frequencies f 1 , f 2 . Now, if the external light and internal light vary, the voltages Vd 1  and Vd 2  being applied to a differential amplifier 8 vary, producing an output signal in the amplifier 8. This causes the motor M of a control unit 9 to run, so that the contact of the changeover device 4a of a frequency changer 4 is moved in the a or b direction, whereby the frequency change ratio is changed. Thereby, the frequency of the oscillator 34 is changed and is so controlled as to become f 1 =f 2 . Next, when shutter release is pushed, a switch S 1  opens and S 2  closes to operate a shutter opening-closing devide 11, but when external light changes during this time, the input f 1  changes to perform correction.

Title: Electrical soldering iron tip
Inventor: IWATA MANABU
IPC: B23K3/02
Filed: 1983-02-15
Abstract: PURPOSE:To form a secure adhesive part and to obviate giving an electrical fault to the materials to be soldered in an electrical soldering iron tip by fitting a ceramics having two projecting ends between the soldering part and the heating part and performing metallized welding. CONSTITUTION:A ceramics 2 consisting of Al2O3 or ZrO2 or the like and having a projecting end shape 4 at both ends is fitted between an electrical soldering iron tip 1 having a recessed end and heating part 1b. The fitting part 4 is joined by metallized joining of a hydrogen compd. method, etc. The stress arising from the difference in thermal expansion between both is decreased as said stress is absorbed by the wide contact area formed of the thickness of the metallized layer and the joining into a projecting shape. The secure joint is thus obtained at all times. The ceramics 2 transmits well the heat but is an electrically non-conductor, and since the ceramics shuts off the electrification charge by electrostatic capacity, the ceramics does not give any electrical fault on the materials to be soldered.

Title: Small screw for eyeglass frame
Inventor: NISHIMURA SUEO
IPC: G02C5/22
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To surely and quickly remove a broken shank from a screw bore by providing a head having a driver groove and a shank formed integrally thereto on a small screw, and forming an engagement part on the screwing start end-side end surface of the shank. SOLUTION: A small screw 10 has a shank 10 and a head 11 formed on one end thereof, and it is formed of copper alloy or stainless steel. A cross driver groove 12 is formed on the head 11 so as to be screwable by plus and minus drivers. A straight line-shaped groove passing the axial center is formed on the screwing start end-side end surface 14 of the shank 10 to form an engagement part 15. Even if the small screw is broken, and the shank 10 is left in a screw bore, a screwing tool such as driver is engaged with the engagement part 15 to screw the shank 10, whereby the shank 10 can be surely and quickly removed from the screw bore. Since the screw bore is never damaged in the removal of the shank 10, a new small screw can be used to perform a sure fastening.
