Title: Hot-cathode electron impact type ion source
Inventor: WATANABE FUMIO
IPC: H01J49/14
Filed: 1983-10-14
Abstract: PURPOSE:To facilitate the attachment and detachment of an annular hot cathode in a hot-cathode electron impact type ion source for a tetrode analyzer by installing the hot cathode independently of an anode by integrating the hot cathode with electron diaphragm electrodes through an insulating material. CONSTITUTION:After grid-like or mesh-like anode 2 is attached to an anodic base plate 11, an annular hot cathode 3 is installed around the anode 2. At the same time, an electron diaphragm electrode 4 is installed between the anode 2 and the cathode 3, thereby constituting a hot-cathode electron impact type ion source for a tetrode analyzer. Here, after an insulating terminal 6 is attached to an electron diaphragm electrode base plate 5 placed over the anode base plate 11 insulatedly from it, the annular hot cathode 3 is fixed to a terminal vertically extending from the terminal 6. As a result, the hot cathode 3 is installed independently of the anode 2 by integrating the hot cathode 3 with the electron diaphragm electrodes 4 and 5 through the insulating terminal 6. Accordingly, it is possible to facilitate the replacement of the hot cathode 3 by simplifying its attachment and detachment.

Title: Wire guide apparatus of discharge processing machine
Inventor: RUDORUFU SHIYUNAIDAA
IPC: B23H1/08
Filed: 1982-10-30
Abstract: In swinging wire guides for generally conical finishing surfaces, the problem exists of a reliable automatic coaxial setting of the guide axes according to the particular angular position of the wire electrode in the workpiece finishing zone. As a solution, the wire guides (DF1, DF2) supported swinging on the support elements (TO1, TO2) are joined together by a coupling device, which has a guide member (FG) joined correspondingly with the support elements. The latter is set by the relative movement of the wire guides (DF1, DF2) to the desired angular position of the wire guides according to the ideal wire guide axis (D-D). Through swinging coupling gears (SK1, SK2) the angle position of the guide member (FG) is transmitted to the wire guides (DF1, DF2). These coupling gears suitably contain a jointed parallelogram (LK) and a rotary coupling member (DK) for the transmission of two swinging movement components, perpendicular to each other, in the sense of a total biaxial forced coupling of the guide member with the wire guides.

Title: Film winding cartridge
Inventor: MURAKAMI MASANORI
IPC: G03B21/11
Filed: 1988-08-01
Abstract: PURPOSE:To perform the winding of a film on a reel automatically from the outset by installing a first energizing part, which energizes a first guide part rockably held by a first arm in a direction of making a first guide part come nearer to a driving part, and a second energizing part which energizes a second guide part rockably held by a second arm in a direction being approximated to the driving pat, respectively. CONSTITUTION:A film is guided to a core 51 of a film reel 5 and an inlet of a first guide part 31, and its tip advances forward so as to be wound on the core. Next, since the outlet side of this first guide part 31 and the inlet side of a second guide part 41 are opposed to each other, the film tip advances forward up to an outlet of the second guide part 41 so as to be wound on the core as well. Since the outlet side of the second guide part and the inlet side of the first guide part are opposed to each other as aforesaid, it enters in an interval between the succeeding film and the core at an inlet of the first guide part. At the outset of winding, a peripheral speed of the core is made somewhat speedier than that of admission of the film into a case, whereby the film is tightly woundable on the core.

Abstract: PURPOSE:To improve durability by adding an epoxy resin, phenolic resin and solvent to a mixture composed of magnetic powder, a polymer selected from the group consisting of PVB, PVFM and PVAC and a solvent and kneading the mixture under the specific shearing stress applied thereto. CONSTITUTION:A mixture composed of 100pts.wt. magnetic powder, 1.5-30pts.wt. the polymer selected from the group consisting of polyvinyl butyral, polyvinyl formal and polyvinyl acetate and 20-60pts.wt. a solvent is kneaded under the high shearing stress applied thereto (the 1st stage). Then 40-740pts.wt. a solvent, 10-70pts.wt. a phenolic resin and 10-70pts.wt. an epoxy resin are added to the kneaded matter and the kneading is accomplished under 100-10,000dyn/cm<2> shearing stress (the 2nd stage). The kneading by the shearing stress in the 2nd stage is accomplished by a device such as, for example, a homogenizer or sand mill which agitates the material at a high rotating speed. The magnetic disc having substantially high durability is thus formed by introducing the 2nd stage in which the materials are kneaded under the shearing stress of the extent of obviating desorption and deterioration of the adsorbed high polymer and the shearing stress enough to attain substantial compatibility with the other binder polymer in addition to the 1st stage in the above-mentioned way.

Abstract: PURPOSE:To obtain a method of surface treatment for inorg. powder without causing secondary aggregation by adding a surfactant to a silane coupling agent expressed by the specified general formula in the process of reforming the surface of the inorg. powder with this silane coupling agent. CONSTITUTION:In the process of reforming the surface of an inorg. powder material (e.g. silica, calcium carbonate, alumina) by using a silane coupling agent expressed by the general formula I, a surfactant is added to the silane coupling agent. In the formula I, R is a methyl or ethyl group, X is a group which reacts with an org. matter and can couple with this org. matter (called an org. reactive group), and (n) is 2 or 3. The org. reactive group X in the molecule of the silane coupling agent is, for example, an org. group such as a hydrocarbon group with at least one substituted functional group such as vinyl group, methacryloxy group, etc. As to the surfactant, a long-chain aliphatic alcohol having low volatility is preferable, and the surfactant is added by about 0.1 - 2 to 1pts.wt. of the silane coupling agent. By this method, the secondary aggregation of the surface treated powder is prevented.

Title: Nonlinear magnetic recording and replay apparatus
Inventor: TAKASHI TERUMI
IPC: G11B5/02
Filed: 1992-07-21
Abstract: PURPOSE:To stably replay also a high-speed recorded signal by a method wherein one out of two write current generation means which are provided with different current values is selected by a selection means according to recorded data. CONSTITUTION:A data conversion circuit 1 holds an output when write data is set at '0' and inverts the output when the data is at '1'. A selection circuit 4 selects a write current circuit 2 when the output of the data conversion circuit 1 is at '0', it selects a write current circuit 3 when the output is at '1', and it makes an electric current flow to a write head 5. When an electric current value is large, a large magnetic field is recorded on a recording medium. For example, when electric current values iW1, iW2 are set so as to match the magnetic-field-to-resistance value conversion characteristic of an MR head 8, a change in a resistance value whose upper and lower amplitude values are equal is caused with reference to an operating point decided by a bias magnetic field generated by a bias conductor 7 and a bias current circuit 9. A constant current (is) from a sense current circuit 10 is read out, it is made to flow to a head 6, it is input to an amplifier 11 as voltage signal, and a replayed waveform is obtained. Thereby, a replay circuit by the high-speed inversion of a bias current in conventional cases is not required.
