Title: Thin-film magnetic head
Inventor: KATO YOSHIAKI
IPC: G11B5/31
Filed: 1989-07-13
Abstract: PURPOSE:To prevent the electrification of magnetic layers by providing a terminal for grounding on the lower magnetic layer. CONSTITUTION:The magnetic head has the lower magnetic layer 2 of a nearly rectangular plane disposed on a substrate 1. A gap for transmitting and receiving signals to and from a recording medium is disposed in the front part between the layer 2 and the upper magnetic layer 6. A coil part 4 is disposed behind the gap between the two magnetic layers as well apart insulating layers 3, 5. Terminal parts 4a, 4b to constitute a juncture between this coil part 4 and an external wiring are disposed behind the coil 4. The part of the intermediate coil winging tends to have the width larger than in the other parts in order to assure the larger number of turns of the coil as far as possible. The part near the rear part disposed with the terminal parts 4a, 4b has a relative margin in disposition. The grounding terminal 8 is disposed between these terminals 4a and 4b and the need for enlarging the lower magnetic layer for the purpose of disposing this grounding terminal 8 is eliminated. The electrification of the magnetic layers 2, 6 is prevented by this grounding terminal 8.

Title: Bath water purifying apparatus and backwashing thereof
Inventor: SUGIMOTO AKITOSHI
IPC: A47K3/00
Filed: 1996-07-09
Abstract: PROBLEM TO BE SOLVED: To obtain a bath water purifying apparatus preventing the deterioration of the capacity of a porous ceramic filter and keeping long-term capacity by filtering bath water purified by a first adsorbing purifying means by a porous ceramic filter and subsequently purifying the purified bath water by a second adsorbing purifying means. SOLUTION: A purifying apparatus 10 passes bath water through the first activated carbon bed 22 wherein activated carbon is held between filters at first to adsorb and remove impurities in bath water. Subsequently, bath water is highly filtered by a porous ceramic filter 24 and, since the ceramic filter has fine pores threedimensionally, org. matter such as floating metal salts and fine particles such as bacteria are also filtered. Since fur or an oil component is removed at first by the first activated carbon bed 22, the blocking of the filter spaces of the ceramic filter is extremely low and predetermined capacity can be developed over a long period of time. Thereafter, impurities, bacteria or org. matter are adsorbed and removed by a second activated carbon bed 28 being a second adsorbing purifying means and the treated water is deodorized and purified to obtain bath water.

Abstract: PURPOSE:To remove effectively fine contaminant attaching to a surface, and prevent the generation of damage on the surface of a body to be treated, by assembling a vibrating plate of high melting point metal and an oscillator, and applying effectively ultrasonic waves in a specified range of frequency to the cleaning liquid in a cleaning tank. CONSTITUTION:A 0.1-0.5mm thick rectangular vibrating plate 6 made of tanta lum is arranged between the upper surface of a base stand 1 and the base surface of a cleaning tank 3. On the base stand 1 side surface of the vibrating plate 6, fourteen pieces of hexagonal vibrators 10 are arranged and fixed so as to closely approach with each other. These vibrators 10 are connected, via a lead plate 11 and a cable 12, to an oscillator 13 which generates hight fre quency at 400-1000kHz and performs a sweep of +2.5kHz width. The vibrators exhibit some irregularity of vibration characteristics depending on the form, the film thickness, etc. The oscillator 13, however, can resolve the decrease of oscillation efficiency caused by the irregularity of vibration characteristics between each vibrator 10.

Title: Demodulation system
Inventor: YAMAMOTO SHUHEI
IPC: H04B3/10
Filed: 1986-07-30
Abstract: PURPOSE:To attain efficient demodulation for each system by changing a sampling frequency so as to attain demodulation. CONSTITUTION:Prior to the detection of an optimum sampling phase, N-time sampling is applied per 1SI from the limitation of accuracy and N times of roll-off operation and demodulation operation are applied. After the detection of optimum sampling phase, the sampling is applied at a timer interval less than 1/2 fmax by the sampling theorem, where fmax is the maximum frequency of an input signal and the roll-off and demodulation operation have only to be applied respectively. Since the sampling frequency up to the detection of optimum sampling phase is high, the titled system is suited to detect the optimum sampling phase by the method independent of the signal pattern, and the demodulation is applied by required and sufficient sampling.

IPC: G01B11/30
Filed: 1989-07-12
Abstract: PURPOSE: To examine the roundness of the surface of the cylindrical surface of an article by interfering the light emitted by a Fizeau interferometer and the light reflected by the conical reflecting surface of the member and inspecting the interference fringe by the interferometer. CONSTITUTION: A Fizeau interferometer 34 introduces the collimated light beam 48 in parallel with the axis of the surface on the conical surface 28. The surface 28 is mirror reflective with 90 deg. of conical surface, and the light beam before incident to the surface 28 is parallel to the axis of the surface 28, and hence the light in the beam 28 is reflected on the surface 28, and then introduced perpendicular to the axis. Accordingly, the light is radially directed on the cylindrical surface 36 of the article 38 to be examined. When the surface 36 is the cylindrical of true circle, the interference fringe formed of the beam 48 emitted by an interferometer 34 and the light reflected on the surface 28 after the reflection on the surface 36 becomes completely regular.  However, if the surface 36 is not the cylindrical of the true circle, the fringe is not completely regular and the irregularity of the fringe can be judged by the aid of the interferometer 34.
