Title: Apparatus for detecting black oxide film in cylindrical hole
Inventor: KAMIMURA TAKEO
IPC: G01N21/954
Filed: 1984-01-26
Abstract: PURPOSE:To certainly detect a black oxide film remaining to the inner surface of a cylindrical hole in a non-ground state, by coaxially inserting a probe main body into the cylindrical hole and detecting infrared rays emitted from the inner surface of the hole by the infrared ray intensity detector in the probe main body. CONSTITUTION:A hollow cylindrical probe main body 2 is almost coaxially inserted into a hole 1. A micromotor 10 and a reflective mirror 11 are attached to the interior of the body 6 of the main body 2 and a lens 14 and an infrared ray intensity detector 15 are assembled in the shell 13 provided in the body 6. Infrared rays are emitted from the inner surface of the hole 1 to pass a window 8 and reflected by the reflective mirror 11 while the intensity of the reflected infrared rays incident through the lens 14 is detected. When the micromotor 10 is rotated, the reflective mirror 11 is rotated and the inner surface of the hole 1 is scanned by the infrared ray intensity detector 15 and electric signal output corresponding to the intensity is obtained while the change in this output is monitored to make it possible to detect the black oxide film 1a remaining to the inner surface of the hole in a non-ground state at the time of grinding.

Abstract: PURPOSE:To easily insert a lead of an electronic part into an inserting hole even if such electronic part has undesirable self-standing capability by acquiring a lead pitch of an electronic part and pressing the body of electronic part toward a reference chuck pawl. CONSTITUTION:A small size variable resistor 1 is taken out of a case with a reference chuck pawl 2 and a chuck pawl 3, it is then moved to the predetermined position of a circuit substrate 7 and the resistor 1 is moved up to the position where the end part of the lead is inserted into a lead inserting hole 8 of the circuit substrate 7. Next, the reference chuck pawl 2 and the chuck pawl 3 are opened so that the resistor 1 can pass therethrough. In this case, the resistor 1 is pressed toward the reference chuck pawl 2 through a part holder 4 by a compression spring 5. While this condition is being held, a part inserting member 6 pushes the resistor 1 from the upper side and the lead thereof is inserted into the lead inserting hole 8 of the circuit board 7. Thereby, automatic insertion of electronic part having undesirable self-standing capability and attitude of electronic part after insertion can be ensured.

IPC: F02P5/15
Filed: 1979-02-08
Abstract: PURPOSE:To improve drivability and stability of an engine by fixing an ignition timing limited in the recommended range if a difference is too great between two values of an ignition timing calculated and another ignition timing prior to it having  been stored. CONSTITUTION:A processing unit 2 in a computer 1 receives each signal from sensors 7-10 to fix a reference value of ignition timing. After comparison of the reference value of an ignition timing with another value of a prior ignition timing  stored in a memory 6, if a difference between the reference value and another prior to it is within a recommended range, the reference value is used for a next ignition timing and if the value is out of the range, a value limited in the recommended range is used. An ignition signal breaks a primary circuit of the ignition coil 13 to produce a high-tension current which is fed to ignition plugs 15-20 across a distributor 14.

Abstract: PROBLEM TO BE SOLVED: To make a receiver used in a spread spectrum communications system small, and to reduce the power consumption of the receiver. SOLUTION: Multipliers 21a-21d, to which period waves shifted by 45 degrees each are given respectively, multiply a received signal with its periodic wave. Limiters 22a-22d binarize the outputs of the multipliers 21a-21d.

Title: Radiation shielding
Inventor: HASHIMOTO KAZUNORI
IPC: G21C11/02
Filed: 1988-01-26
Abstract: PURPOSE:To eliminate shielding devices substantially and to intend an effective use of a space in a facility, by arranging and placing a lead material at a peripheral area of a flowing zone which forms a duct. CONSTITUTION:A tunnel chamber for main steam 1 is separated from a lower radiation dose area 3 by a shielding wall 4. This tunnel 1 is cooled down by a local cooler 5 because a temperature of the tunnel 1 rises high being heated by a steam flowing inside of a main steam pipe 2. A suction duct and a venting duct 6 and 7 of the cooler 5 penetrate through the shielding wall 4 independently. In this situation, radiation leaking from a penetration 8 is shielded by a lead 13 placed at a peripheral area of a flowing zone 12 which forms the ducts. A thickness of the lead is determined according to an amount of radiation to be shielded. With this constitution, a space required for shielding diminishes to 1/10 of an ordinary one and an available space in a low radiation dose area increases.

IPC: G03B27/54
Filed: 1992-01-29
Abstract: PURPOSE:To prevent the life of a copying lamp from being short and to prevent the temperature of a peripheral part from exceeding a tolerance limits by preventing the voltage of the copying lamp from being corrected and using a voltage value before the calculating processing of the voltage of the copying lamp as it is when the voltage of the copying lamp calculated based on the density, etc., of an image exceeds an upper limit value. CONSTITUTION:Ordinarily, the voltage of the copying lamp 10 is calculated in accordance with toner density formed on a photosensitive body 1 and the surface potential of the photosensitive body, and the calculated voltage of the copying lamp is compared with the previously set upper limit value of the voltage of the copying lamp. In the case that the calculated voltage of the copying lamp exceeds the previously set upper limit value, the voltage of the copying lamp before calculating processing is used as it is and the voltage value obtained by calculating processing is cancelled. Since the voltage of the copying lamp is prevented from exceeding the upper limit value, the life of the copying lamp is prevented from being short and trouble such as the abnormal temperature rise of the peripheral parts of the copying lamp such as a table glass is prevented.
