Title: Test method for anti-corrosion characteristic
Inventor: NISHIKAWA SHOZO
IPC: G01N27/26
Filed: 1994-08-29
Abstract: PURPOSE: To correctly evaluate corrosion of a metal material with easily in a short time with small quantity of test water by soaking a metal material electrode and a collate electrode in the water containing active oxygen generating source and oxidation reduction pigment. CONSTITUTION: Metal sample electrodes 1A, 1B and 1C and a collate electrode 2 are soaked in water 3 containing active oxygen generating source and oxidation reduction pigment. And, a potential difference meter 5 which measures the potential difference between the electrodes 1A, 1B and 1C and the collate electrode 2 is connected through an electrode switching device 4. A recorder 6 displays the measurement result by the potential difference meter 5. As an active oxygen generating source, xylose which is easy to generate active oxygen through automatic oxidation reaction in water, etc., are used. When the xylose is added to the water, the active oxygen is generated, and, in the process where the active oxygen is reduced, electron is taken out of the metal sample, as a result, corrosion advances, so that it is measured as potential rising.  Thus, based an potential changes between the metal sample electrodes 1A-1C and collate electrode 2, anti-corrosion characteristic of metal material is evaluated.

Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To detect the surface position information of a wafer and to align the wafer with the focus plane of a projection optical system by controlling the motions of light-projecting means and light-receiving means independently and synchronizing them with the drive of a stage by a driving means and advancing the motion of the light-projecting means to that of the light-receiving means.

Title: Deglitch circuit
Inventor: SUGAWARA MASAHIKO
IPC: H03M1/08
Filed: 1989-08-08
Abstract: PURPOSE:To eliminate the glitch of a D/A converter and to prevent the level reduction in a high band due to an aper ture effect by selecting and using a signal in the period free from glitch of the output signal of the D/A converter. CONSTITUTION:The digital input signal of a D/A converter 1 is changed at the time of the change from the low level to the high level of a transfer clock signal D of the digital input signal of the converter 1. Consequently, an analog output A is changed stepwise at the time of the change from the low level to the high level of the signal D. A delay circuit 5 outputs a signal E obtained by delaying the signal D by 1/4 period, and an AND 9 operates AND between signals D and E to output a signal F. The signal F is in the high level for 1/4 period of the signal D, and the signal A is inputted to an analog switch 2 from a terminal 6 and this switch 2 sends a signal D to an amplifying circuit 3 while the signal F is in the high level. Since the signal A is delayed behind the stepwise change by the delay time, the signal A is free from glitch, and the signal B inputted to the circuit 3 is free from glitch and the signal value is stable.

Title: Optical disk device and its tracking control circuit and tracking position changing method
Inventor: YAMAMURO MIKIO
IPC: G11B20/12
Filed: 1995-08-10
Abstract: PROBLEM TO BE SOLVED: To correctly change a tracking position between a groove and a land by adding a jump pulse to be changed with specific waveforms to a tracking driving signal. SOLUTION: A track error signal (TE) becomes larger in a difference between (0) as the position of a laser beam is separated from the center of a track. For example, in the land, when the position of the beam is separated in the outper peripheral direction of a disk, the signal changes in a positive direction and in the groove, when the beam is separated in the outer peripheral direction of the disk, the signal changes in a negative direction. Respective tracks are selectively tracked by the polarity difference of signals. When the beam is started to be moved to the land adjacent to an outer periphery in performing a reproducing in the groove, a CPU turns a tracking servo loop OFF by turning a switch 71 OFF. Next, the CPU turns the polarity of the TE to a land side by changing over a switch 72.  Then, the CPU moves the position of the laser beam to the outer peripheral direction by transmitting a jump pulse changing to a positive at first and to a negative next to a driving circuit 76 via an adding part 75 and finally turns the switch 71 ON.

Title: Resonance type switching power supply
Inventor: KOBORI KATSUMI
IPC: H02M3/337
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To increase the efficiency of a current resonance type switching power supply. SOLUTION: In a switching power supply, switching current is caused to flow in a primary winding L1 of a transformer by alternate turning ON of MOS transistors Q1 , Q2 and then alternating power is transmitted to the secondary side. The alternating power appearing in a secondary winding L2 is rectified in full-wave by diodes D1 , D2 . By connecting resonance elements Cr, Lr to a tertiary winding L3 coupled to the insulation transformer T, the primary side can be turned into a resonance state, thereby this switching power supply becoming a current resonance type switching power supply. Since a leakage inductance of the transformer is not a resonance element, windings of the insulation transformer are tightly coupled.  Furthermore, resonance current is not directly turned ON and OFF, and therefore a peak value of the primary current is lowered and a switching loss and a loss due to ON-state resistance can be reduced.

Abstract: PURPOSE: To develop a separating device for foreign containers like a paper cup and a can, or an aluminum can and a steel can. CONSTITUTION: A throw-in inlet 3 for beverage containers is disposed in a recovery vessel. A door 6 having an opening/closing regulating means and a sensor for sensing a paper cup and an empty can are disposed in the throw-in inlet 3.
