Patent JP-S55142121-A (JP)
Title: Transferring device
Inventor: PEETAA ANDAASU
IPC: F16C39/06
Filed: 1980-04-14
Abstract: A clutch release device is provided in which contact-free displacement of a rotating displaceably mounted member along the axis of rotation thereof can take place. A rotating member (5) which engages diaphragm string tongues (1) is axially displaced upon axial movement of a non-rotatable member (9) by a release fork (13), the displacing force being provided by mutual repulsion of magnets (15, 17) on the members (5, 9) which also limits the approach of the two members towards each other. In this manner wear between rotary parts is obviated and noise is reduced. In another embodiment, energisation of an electromagnet on the non- rotatable member attracts a soft iron rotatable member bur axial displacement of the latter member is limited by a stop co-operating with the diaphragm spring tongues engaged with the rotatable member. <IMAGE>

Title: Production of highly purified n-carbonylamino acid ester
Inventor: OSABE MASAMI
IPC: C07C233/47
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To produce the subject compound in a simple method suppressing generation of impurities as little as possible by reacting an amino acid ester with phosgene in an organic solvent containing an alcohol amount smaller than a specific value. SOLUTION: This compound (e.g. N-carbonyl-L-phenylalanine methyl ester) is obtained by reacting an amino acid ester with phosgene by using an amount of alcohol in the organic solvent as <=2.5 wt.% based on the amino acid ester in an organic solvent. The amino acid ester is obtained by subjecting an amino acid to esterification with an acid catalyst in an alcohol and is preferably an amino acid ester having an aromatic ring (e.g. a methyl ester body or ethyl ester body of phenyalanine or S-phenylcysteine). Preferably, a using amount of phosgene gas is 1-10 times of the amino acid ester and the reaction is performed at 30-200 deg.C.

Filed: 1986-03-07
Abstract: PURPOSE:To detect a shape at low cost and with high accuracy by providing a bearing which has supported a roller divided to a roller shaft, by making an elastic body intervene, and detecting a displacement of the roller. CONSTITUTION:A shape detecting device A is provided, for instance, between stands of a cold rolling mill or on its delivery, and a band-shaped body, for instance, a strip contacts a roller 4 and made to pass through. In this case, the roller 4 receives force from the strip, and by this force, an elastic body 2 which has been provided on the outside periphery of a roller shaft 1 is deformed and the roller 4 is displaced, but the roller 4 is displaced in accordance with the force received from the strip, since it is divided and provided in the direction of the roller shaft 1. That is to say, a degree of the displacement of the roller 4 is changed in accordance with a tension distribution in the width direction of the strip, therefore, by detecting it by a roller displacement gauge 9, the tension distribution of the strip can be detected with a high accuracy, and from this detected value, a shape of the strip is known with a high accuracy.

Title: Automatic line for assembling optically coupled device
Inventor: HIRASAWA HIROKI
IPC: H01L31/12
Filed: 1992-03-09
Abstract: PURPOSE:To prevent the decline of the working ratio of the mounters and bonders in the MBM process and improve the productivity by arranging a plurality of sealing devices in parallel with mounting devices and bonding devices. CONSTITUTION:A continuous lead frame film for light-receiving devices are fed through process. After the lead frame film is passed through a coupling device 4, the lead frame film is cut into a strip of 12 lead frames by a real- cutting and distributer 5, and then the distributer 5 pushes out the strips into a vacant sealing device 6 by judging the condition of sealing devices 6 and 7. Next, the lead frames are sealed with epoxy polymeric resin, after detecting a sealing position by use of sealing-position detecting holes 19 and 24 by the sealing devices 6 and 7 arranged in parallel. Then, the strip of 12 lead frames is housed in a housing device 8. Therefore, if three sealing devices are arranged in parallel, the amount of lead frames produced by one sealing device will be three times as much as that of a conventional single sealing device. As a result, decline of working ratio is prevented as a whole system, and the production amount can be increased.

Title: Apparatus for separating and capturing ultrafine particles
Inventor: KANAMARU MASATOSHI
IPC: B01J19/00
Filed: 1986-03-10
Abstract: PURPOSE:To form and capture ultrafine particles continuously for a long time by transferring the ultrafine particles formed in a generating chamber to a filter mechanism by gaseous flow to separate and capture the particles and applying oscillation to a filter thereby collecting the particles in a large-capacity capturing chamber. CONSTITUTION:The ultrafine particles formed in the ultrafine particles generating chamber 1 are entrained in the flow of a carrier gas and are transferred up to the oscillation filter mechanism 2. The ultrafine particles and the carrier gas are separated in said mechanism. The carrier gas is returned by a circulation pump 4 to the generating chamber 1. The ultrafine particles captured by the filter mechanism 2 do not stick to the filter surface and are collected into the large-capacity capturing chamber 3 as the filter is under oscillation. Valves 7a, 7b are closed and the ultrafine particles are dispersed by an ultrasonic oscillator 6 when a large amt. of the ultrafine particles are collected in the capturing chamber 3. The capturing chamber 3 is thereafter exchanged. A large amt. of the ultrafine particles are thereby efficiently and easily captured in the dispersed state.

Title: Magnetic head
Inventor: TAKAHASHI TAKESHI
IPC: H01F10/12
Filed: 1987-03-05
Abstract: PURPOSE:To permit recording and reproduction of signals with high efficiency even in a high-frequency band by using a multi-layered magnetic core including thin ferromagnetic films which are different in the direction of anisotropy as a head core. CONSTITUTION:The magnetic core 3 consisting of the multi-layered films is constituted by laminating the thin ferromagnetic films 1 consisting of an amorphous magnetic alloy or 'SENDUST(R)', etc., via thin insulating films 2 consisting of SiO2, etc. The core 3 is constituted of both of the films 1 which have the uniaxial anisotropy within the plane of the magnetic path and in which the directions of the easy axes thereof intersect orthogonally with the plane of the magnetic gap or parallel therewith as shown by arrows. The magnetic gap is formed by sandwiching the core 3 with nonmagnetic substrates 4 consisting of barium titanate ceramics, etc., and joining the same to opposed cores having a winding 5 by means of bonding glass 6. Since the greater part of the magnetic paths of this magnetic head operate with an initial magnetic permeability characteristic and, therefore, the head exhibits high head efficiency even at a high frequency of >=30MHz.

Title: Light control element and light control composite element
Inventor: MAEDA YOSHINOBU
IPC: H01S3/06
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To negative-control the intensity of incident light over a wavelength range for optical fiber communication stably, according to the intensity of the incident light itself, by controlling the respondable wavelength range of a light transmitting medium by a voltage applied to an optical path. SOLUTION: Three pairs of control electrodes 2A and 2B, 2C and 2D, and 2E and 2F being opposed to each other are formed on a pair of principal surfaces of a bulk substance 1 which forms an optical path. Each pair of opposed control electrodes is arranged on a light control element 5C, 5D, 5E along the direction of transmission of light inside the bulk substance 1. Each respondable wavelength range of the elements 5C-5E is shifted as shown by 20A-20C. If incident light having a wavelength of 1.532 μm for example enters the light control composite elements, light is transmitted without occurrence of a negative absorption phenomenon in the elements 5C, 5D, but the negative absorption phenomenon occurs in the element 5E. Accordingly, it is possible to form a light controlling element capable of negative-controlling the intensity of incident light in a wavelength range for optical fiber communication stably, according to the intensity of the incident light itself.
