Title: Magnetic recording and reproducing device
Inventor: TAKEUCHI MOTOHIKO
IPC: H01F38/14
Filed: 1985-03-29
Abstract: PURPOSE:To prevent invasion of crosstalk component by connecting an impedance means showing a low impedance at a frequency of a signal invaded as crosstalk in parallel with a winding of a rotary transformer so as to bring the winding into nearly short-circuit state to the crosstalk component. CONSTITUTION:A series resonance circuit 25 comprising of a coil L and a capacitor C is connected in parallel with a stator winding 23. The resonance frequency of the series resonance circuit 25 is set to the frequency band of a sound signal recorded/reproduced by a rotary head for sound signal. Then the series resonance circuit 25 has the lowest impedance at the frequency band of the sound signal, and no crosstalk component is sent in the signal at the frequency above because it is short-circuited across the winding 23, and the same effect as a short ring is obtained. This is applied also to the sound signal rotary head.

Title: Amorphous iron alloy having high strength and resistance to fatigue, general corrosion, pitting crevice corrosion, stress corrosion cracking and hydrogen embrittlement
Inventor: MASUMOTO TAKESHI
IPC: C22C30/00
Filed: 1984-04-02
Abstract: PURPOSE:To provide a titled alloy obtd. by forming Fe contg. a specific amt. of Cr, Ni and B as metalloid into an amorphous structure. CONSTITUTION:An amorphous iron alloy consists, by atom%, of 1-40% Cr and 0.01- 40% Ni, contains 7-35% B as metalloid and consists of the balance Fe and has high strength and resistance to fatigue, general corrosion, pitting, crevice corrosion, stress corrosion cracking and hydrogen embrittlement. The alloy is formed by putting a raw material metal into, for example, a quartz tube 1 provided with a nozzle 2 for ejecting the metal in a horizontal direction at the lower end, melting the metal in a heating furnace 4 and rotating a drum 5 formed of Al, etc. lined with a copper plate 7, etc. at a high speed by a motor 6. The tube 1 is then lowered by an air piston 8 to bring the nozzle 2 opposite to the inside surface of the drum 5. When the tube is raised thereafter, a gaseous pressure is exerted approximately simultaneously on the metal 3, by which the metal is gushed to the inside surface of the drum and is cooled at an extra- high speed. The amorphous metal is thus formed. An inert gas 9 is continuously fed to the inside of the tube 1 to prevent oxidation of the metal 3.

As a result, a bonding tool 4 is lowered in the direction of an arrow 16a. At first a contact body 14 is contacted with the lead 13 and the bump 11 with compressing force corresponding to the air pressure PO. Then the voltage value of the signal SP is changed into VB, which is larger than VO, is applied to the transducer 6 from the device 7. Then the compressed air is supplied into the air cylinder 5, and the compressing air is increased rapidly to the proper pressure. After the specified time, the application of the signal SP is stopped.

Title: Method for measuring vtr magnetic head
Inventor: SHINODA MAKOTO
IPC: G11B5/455
Filed: 1989-03-20
Abstract: PURPOSE:To obtain an azimuth angle with high accuracy when a head is assembled by detecting the edge position of an azimuth marker provided at a part extending from a head gap by photolithographic technique. CONSTITUTION:A head gap 3 to generate recording/reproducing magnetism is provided at the tip plane 2a of a head, and also, upper and lower azimuth markers 4a and 4b are provided at an extension line 5 extending from the head gap 3. Also, the head 2 is manufactured separately in a manufacturing process setting the extension line 5 as a boundary. At such a case, when the azimuth angle 0 is found from the head gap 3 and the azimuth marker 4a, high accuracy can be obtained by finding it from distances Ld and Lm with large measuring distance if the measuring resolution of the distances Lr, Ld, Lw, and Lm are same. Measurement is performed by magnifying the tip plane 2a of the head 2 by an optical device 7, and performing it visually by displaying it on a TV monitor 9 after applying the photoelectric conversion of a magnified image by a solid-state camera 8. In such a way, since the azimuth angle can be measured from the measured value of the distance sufficiently lower than the resolution distance of an edge point, high accuracy is obtained.

Abstract: PURPOSE:To effectively use the lubricating oil of a planetary gear mechanism and simplify an oil feeding mechanism by linking the hub of a friction engaging element to a carrier on the outer periphery of the planetary gear mechanism and forming an oil passage for allowing lubricating oil pass through on this hub. CONSTITUTION:In a planetary gear mechanisms 22 consisting of a sun gear 221, planetary pinions 224, and a ring gear 222, the planetary pinions 224 are rotatably supported by a carrier 223 and a friction engaging element 53 is provided on the outer periphery thereof with its hub 534 being linked to the carrier 223. Since an oil passage 126 for allowing lubricating oil which lubricated the friction engaging element 53 to pass through is formed on the hub 534, oil which lubricated the planetary gear mechanism 22 passes through the oil passage 126 due to centrifugal force to be sent to the friction engaging element 53. Thus, by effectively using a large quantity of oil used by the planetary gear mechanism, the quantity of oil for lubrication and cooling can be reduced while simplifying an oil feeding mechanism.

Abstract: PURPOSE:To provide an environment controller for a step and repeat align capable of being used at a time when a fine pattern is formed by employing a chemical amplification type resist. CONSTITUTION:The temperature and relative humidity of air taken in from an air intake 3 by a pressure air blower 5 are controlled by a temperature and relative humidity control system 6, and air is flowed into a chamber 2 through an adsorbent unit 1 and an HEPA filter 7.
