Title: Barrel polishing method applied together with chemical polishing
Inventor: KOBAYASHI HISAMINE
IPC: C23F3/00
Filed: 1983-04-07
Abstract: PURPOSE:To improve the efficiency and quality of barrel polishing by using a proper amount of persulfate as a compound for the barrel polishing instead of water and a compound conventionally added upon polishing the barrel. CONSTITUTION:A polishing material, persulfate, and water, and a workpiece made of copper or a copper alloy, or a workpiece made of steel are inserted into a polishing tank, for barrel polishing. Sodium persulfate, potassium persulfate, and ammonium persulfate are proper for a chemical polishing agent, and sodium persulfate is most suitable from a viewpoint of a fact that copper ions can be entirely removed by neutralization therefrom without any production of a copper ammonium complex in the case of waste water disposal in industrial mass-production. The concentration of the chemical polishing agent is effective in 4-150g/l, and that other than this range is not practical because the effect of smoothing a workpiece is reduced or its surface is made rough. The surface of the workpiece after barrel polishing is colored brown for copper or a copper alloy or gray for steel, but it is cleaned with a dilute acid solution, and then subjected to a glazed finish by the usual barrel polishing.

Title: Advance-retreat detectingly-discriminating device of moving object such as automobile and aircraft by ultrasonic wave or electromagnetic wave, and speed measuring device and advance-retreat alarm transmitting device
Inventor: NISHIZAWA TETSUYA
IPC: G01S15/10
Filed: 1995-02-13
Abstract: PURPOSE: To detect an advance and a retreat of a moving body by obliquely emitting an ultrasonic wave or an electromagnetic wave toward the ground surface from an echo sound transmitter installed on the moving body, receiving a reflected wave by a separately arranged echo sound receiver, and comparingly discriminating a difference in its propagation time between stopping time and moving time. CONSTITUTION: When an automobile stops, an ultrasonic wave pulse from an ultrasonic wave receiver of a point A is reflected at a point B, and enters an echo sound receiver at the point A. This propagation time and a distance are respectively denoted by (t0 ) and (a+b2 ). When the automobile advances at speed V, a pulse from an echo sound transmitter A is reflected at the point B, and enters the echo sound receiver moved to a point C from a point A1 . Propagation time and a distance at this time are respectively denoted by (t) and (a+b). Here, since (b<b2 ) is realized, (t-t0 <0) is realized. Similarly, when the automobile retreats, (t-t0 >0) is realized. This is when an ultrasonic wave is emitted backward, and when it is emitted forward, a positive and a negative become inverse.  Therefore, a positive or a negative of (t-t0 ) is detected, and advance time and retreat time can be judged.

Abstract: PURPOSE:To obtain an electron lens having a small astigmatism and a small spherical aberration, increase the focusing degree of electron beams, and improve the resolving degree of a picture surface by providing three circular beam-passing holes in each of two box-like electrodes, which are opposed and form an electron lens, in an in-line arrangement so that the three holes are continuous. CONSTITUTION:Three circular holes (a) are provided in each of the opposed surfaces of a main-lens-side third grid 5 and a fourth grid 4, which face to one another so as to form an electron lens. The diameter of the above circular holes (a), which are connected to each other, is either equal to the distance between the holes (a) or larger than the distance between the holes (a). A cylindrical electrode 10 is provided with three independent circular holes (a) so that these holes (a) correspond to the above holes (a). Owing to the above constitution, the  aperture of a main lens becomes close to that of the holes (a) of the opposed  surfaces, and the angular symmetric property of the equipotential surface is relatively excellently secured by the cylinder electrode 10. Consequently, the electrostatic lens has a balanced astigmatism and a balanced spherical aberration.

IPC: G05B9/02
Filed: 1980-05-09
Abstract: PURPOSE:To protect a device to be controlled from errorneous control, by discriminating the malfunction of a control part to reset the control part when the phase relation between the detecting output and the synchronizing signal is shifted and disturbed. CONSTITUTION:Since a detecting signal of a specific pattern is output at a constant interval when the operation is normal, the detecting signal (a) of the specific pattern is output from a control part 1 in a position other than the normal position if the time to the next specific pattern output is shortened or extended due to program runaway, etc. This abnormality is detected by the shift of the phase between the signal (a) and the synchronizing signal (b) in a detecting circuit 4 and an NAND gate 7, and the abnormal operation is recovered. If another control signal is output from the control part 1, the control signal from an output line 3 of the control part 1 is latched in a latch 10 by the latch signal from a output line 9, and this data continues to be output to a device 2 to be controlled until the next latch signal is generated.
