Title: Detection method for metal
Inventor: HASEGAWA AKIRA
IPC: G01V3/11
Filed: 1994-01-28
Abstract: PURPOSE:To provide a noncontact detection method for conductor, e.g. a metal. CONSTITUTION:The metal detector comprises an exciting coil connected with a pulse generator, a receiving coil, and a voltage amplifier for the receiving coil having-a switch circuit. Positive and negative pulse currents are fed to the exciting coil to induce an eddy current in a detecting conductor and a switch functions at a moment of time when the residual energy of the exciting coil is attenuated sufficiently. Furthermore, the voltage across a detection coil is detected by means of an amplifier synchronized with the exciting pulse. Subsequently, only the eddy current flowing through the detecting conductor is detected selectively.

Title: Electron gun for image pickup tube
Inventor: SAKAI HIDEYUKI
IPC: H01J29/48
Filed: 1984-02-15
Abstract: PURPOSE:To obtain an electron gun which causes little picture distortion or resolution degradation in the peripheral area of a screen by expanding the opening end of an acceleration electrode on the mesh electrode side into a funnel shape, even when the diameter of the electron gun is small. CONSTITUTION:An acceleration electrode 6 is set on the negative electrode side adjacent to a mesh electrode 4 placed opposite to a light conductive film 2, and the opening end of this acceleration electrode 6 on the side of the mesh electrode 4 is widened into a funnel shape. Thus a mesh support 18a is of a cylindrical shape with an opening end only, having no turnups on the side of the target 2; therefore its diameter can be made larger as compared to those in use up to now. At the opening of the 5th grid 6a on the mesh side, a funnel-shaped opening 20 is made to uniformalize the potential distribution, and the diameter of a collimation lens is enlarged, obtaining almost the same effect as when the diameter of the 6th grid 5 is expanded as a whole.

Title: Control of air conditioner
Inventor: TANAKA HIDEKI
IPC: F24F11/02
Filed: 1979-03-07
Abstract: PURPOSE: To save energy by a method wherein high-power heating or low-power heating is conducted accordingly as room temperature is below or above a set temperature in the case where the low-power heating cannot raise the room temperature to the set temperature, and low-power heating is conducted or stopped accordingly as the room temperature is below or above a set temperature in the case where low-power heating suffices.  
     CONSTITUTION: Where room temperature T r  is below T 3 , a motor for a compressor 1 is operated in a two-pole heating mode (high-power heating) while T r  is below a set temperature T 1 , and is changed over to a four-pole heating mode (low-power heating) when T r  is raised beyond T 1 . Where low-power heating raises T r  beyond T 1 , the four-pole heating (low-power heating) is conducted when T r ≤T 1 , and the compressor 1 is stopped when T r >T 1 . Where T r  falls to or below T 3  irrespective of low-power heating, the former heating pattern is conducted again. Thus, wasteful heating operation can be prevented. By the way, cooling operation by use of a change-over valve 8 is low-power cooling.

Filed: 1990-02-05
Abstract: PURPOSE:To reproduce a signal with small pulse width distortion by providing a voltage follower having two input terminals and inputting a guard voltage and an auxiliary voltage respectively to each terminal. CONSTITUTION:The receiver is provided with a voltage follower 7 having two input terminals 8, 9 and generating a voltage equal to a voltage applied to other input terminal when one input terminal is reset.

Filed: 1987-02-06
Abstract: PURPOSE:To improve the transfer efficiency of signal charge and to eliminate the clamping errors of an optical black signal, by providing a charge detecting part upward or downward of a vertical register-bus line. CONSTITUTION:A charge detecting part 7 is provided upward or downward of a vertical registor-bus line part 5A. Thus the bumber of bits in a dummy part 6A of a horizontal registor part 6 is decreased, or the dummy part 6A itself is removed. Therefore, the transfer time of the signal charge for one horizontal line, which is transferred from the vertical register 3 to the horizontal register part 6, to the charge detecting part 7 can be shortened. The transfer time of the signal charge, which is read out of the vertical register part 3, can be increased 7 accordingly. The transfer time from the vertical register part 3 to the horizontal register part 6 can be also increased. The number of the bits of an optical black signal can be increased. Therefore, the transfer efficiency of the signal charge in the vertical register part 3 and the transfer efficiency of the signal charge from the vertical register 3 to the horizontal resister part 6 can be improved. The clamping errors of the optical black signal can be eliminated.
