Title: Device for continuously pickling band steel
Inventor: NAGAI NAOYUKI
IPC: C23G3/02
Filed: 1989-07-20
Abstract: PURPOSE:To continuously and uniformly pickle a band steel by providing plural horns provided with a vibrator on the upper and lower parts of a pickling tank to form a sound field. CONSTITUTION:A diaphragm 8 is fixed on the upper and lower parts of a pickling tank 2 in the continuous pickling device for a band steel, and the tips of the horns 7 provided with a vibrator 6 are brought into contact with the diaphragm 8. When a high-frequency current or a high-frequency voltage is impressed on the vibrator 6, the vibration of the vibrator 6 is transmitted to the horn 7, and the band steel 1 is uniformly vibrated in its cross direction by the horn 7. Consequently, a sound wave is similarly radiated into the pickling soln. 3 from the diaphragm 8, and a uniform sound field is formed. Cavitation is caused in the pickling soln. 3 by this sound field, the collapsing pressure is transmitted to the band steel as an impulse wave, and uniform descaling is accelerated.

Title: Magneto-optical memory device
Inventor: OKAZAKI YUKINORI
IPC: G11B11/105
Filed: 1987-07-24
Abstract: PURPOSE:To attain overwrite equivalent to that of a magnetic disk only by overwriting new information without previously erasing an already formed information pit to rewrite information. CONSTITUTION:The 2nd optical spot 5 having almost the same center as a 1st optical spot 4 and having a diameter larger than that of the 1st optical spot is converged upon a recording film 2 in addition to the 1st optical spot 4 and the intensity of a 2nd optical spot 5 is modulated by an information signal 18 to be recorded. When the intensity of the 2nd optical spot 5 is changed by the signal 18, temperature around an information recording position is changed between a temperature more than a compensating point and a temperature close to a room temperature, the direction of a magnetic field applied to the information recording position is inverted and the magnetizing direction of a magnetic domain recorded in accordance with the signal 18 is also inverted. Thereby, information can be rewritten only by recording a new signal on a previously recorded signal without executing erasing operation. In case of using the device also as a data file, information can be rapidly overwritten.

Title: Solenoid valve
Inventor: ENOMOTO SHIGEIKU
IPC: F02M41/12
Filed: 1993-07-28
Abstract: PURPOSE:To ensure operation by preventing a needle valve from malfunctioning because of air remaining in the armature chamber of a solenoid valve. CONSTITUTION:When this solenoid valve is designed as the solenoid spill valve of a fuel injection system, spilled fuel is forced to overflow from a pressure chamber 52 through a passage 12, the valved portion 24 of a needle valve 20 and a passage 14, and a relief line (spring chamber 16) located downstream of the needle valve 20 and an armature chamber 32 are communicated with each other by a communicating line 82 provided with a constriction means. Part of the spilled fuel flowing through the relief line is forced to flow into the armature chamber 32 after its pressure is reduced by the constriction means, so the spilled fuel is allowed to flow out into a low-pressure chamber 36 along with air remaining in the armature chamber 32. Therefore, even if air remains in the armature chamber 32 during assembly of the solenoid spill valve, it is rapidly expelled out, eliminating the possibility of the needle valve 20 malfunctioning.

Title: Actuator driving device for optical recorder and reproducer
Inventor: SASAKI TAKESHI
IPC: G11B21/08
Filed: 1991-07-26
Abstract: PURPOSE:To always correctly and appropriately compensate a speed signal. CONSTITUTION:A pulse cycle detecting equipment 7 detects the pulse cycle of a track crossing signal 9 and outputs result to a microprocessor 1. In the meantime, the speed signal outputted by an F/V converter 5 is converted into a digital signal by an A/D converter 6 so as to be supplied to the microprocessor 1. The microprocessor 1 obtains the actual track crossing speed of a laser beam spot by the pulse cycle from the detecting equipment and compares it with the signal from the A/D converter 6. The amplification degree of a gain switching circuit 8 is controlled based on the comparison result in such a way that difference between the actual track crossing speed of the laser beam spot and speed expressed by the speed signal 14 becomes smaller.

Title: Flat-bed printing machine
Inventor: SERIZAWA SHOGO
IPC: B41F15/40
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To provide a flat-bed printing machine which can reduce the lowering of positional precision of printing elements due to tilting of a frame and which is easy to handle. SOLUTION: A screen 2 stretched to be flat on a frame 1 is set parallel to a workpiece 4 with a small gap between. While a pressure is applied onto the screen 2 by using a squeegee 3, the screen 2 in the part through which the squeegee 3 has passed is detached from the workpiece 4 sequentially by tilting the frame 1 with the movement of the squeegee 3 and thereby printing is conducted. In this flat-bed printing machine, the central axis 5 of tilting of the frame 1 is disposed at a position within 1 mm from a part 6 of connection of one side of the frame 1 with the screen 2. Since the distance from the part 6 of connection to the central axis 5 of tilting is short, the range of variance of a tensile force acting on the screen 2 on the occasion when the frame 1 tilts with the movement of the squeegee 3 is reduced and, consequently, printing of high positional precision can be executed.
