Title: Flow controller
Inventor: NANAO TERUAKI
IPC: G05D7/06
Filed: 1984-07-19
Abstract: PURPOSE:To realize plural functions provided to each valve with one kind of specification of a flow controller by realizing selectively a reducing valve function, flow control valve function, 2-stage switching type reducing valve function and an emergency shut valve function with a mode designation operation only. CONSTITUTION:When the setting mode is a reducing mode (a), a valve 1 is operated automatically by keeping a detected pressure P2 of a secondary pressure sensor 11 within the permissible range of a setting pressure Ps. In case of the flow control mode (b), the valve 1 is operated automatically so as to keep the flow Q calculated by an operation circuit 12B within the permissible range of a setting flow Qs. In case of the 2-stage switching reducing mode (c), the detected pressure P2 is kept within the permissible range of the pressure Ps when the flow Q is less than the flow Qs, and the valve 1 is operated automatically so as to open fully the valve when the flow Q is the Qs or over. In case of the emergency shut mode (d), the valve 1 is operated automatically to keep the valve in the fully closed state when the flow Q is less than the Qs and so as to close fully the valve when the flow Q reaches the Qs.

Title: Mold release agent for reaction injection mold
Inventor: YASUDA HIROKO
IPC: B29C45/00
Filed: 1989-06-14
Abstract: PURPOSE:To satisfy performance as a mold release agent with favorable stability, by constituting the mold release agent so that the same is of a wax solution obtained by dissolving wax into a specific organic solvent and the same becomes transparent at an ordinary using temperature. CONSTITUTION:A matter which has ignition point of less than 21 deg.C and falls under a regulation of the first petroleum class of the fourth class in the Fire Services Act is used as an organic solvent. A matter which is dissolved transparently into the organic solvent at an ordinary using temperature, for example, of 5-30 deg.C is adopted as the wax and, for example, petroleum series (oils and fats series) wax of paraffin series wax or octadecyl vinyl ether series wax is preferable. With this construction, since there is no precipitation of wax contents at the time of application of a mold release agent (wax solution), agitation means for prevention of the precipitation is not required and defective jamming of a spray gun is not generated due to favorable compatibility between the wax contents and solvent.

IPC: H01M50/409
Filed: 1978-12-11
Abstract: PURPOSE:To control overcharge to a minimum by adding an arrestor to catch dissolved in antimony ion in electrolyte to the material of isolating plate. CONSTITUTION:An isolating plate made of pulp, a synthetic resin, a rubber, etc., contains an arrestor to catch dissolved antimony ion in electrolyte, e.g., tannic acid, sodium alizarin sulfonate, salicylic acid, p-cresol, resorcinol, etc. The arrestor in either liquid or powdery is contained in the isolating plate by attaching to the surface of the isolating plate, by mixing it in the materials of the isolating plate, by attaching it with a binder such as phenol resin, etc., or by melting it with a thermal plastic resin present in the isolating plate materials. The preferred amount of the arrestor is 5% or more of the weight of the isolating plate. Thus, the deposition of antimony ion eluted from anodic plate into electrolyte can be suppressed, thus permitting the enhancement of cathodic potential and also the reduction of overcharge to a minimum.

Filed: 1986-06-27
Abstract: PURPOSE:To make it possible to perform excellent etching and ion implantation and to form a homogeneous thin film, by providing a magnetic field type quadrupole mass spectrometer, and selectively guiding out ions from discharge plasma. CONSTITUTION:A guadrupole mass spectrometer is formed with an iron core 17 and an electromagnetic coil 18. The mass spectrometer is attached around a mass analyzing chamber 19. When the distribution of a magnetic field, which is formed with the electromagnetic coil 18, satisfies ECR conditions at a point (x), which is an inner point from a lead-out electrode 5 in a plasma forming chamber 11, ECR is generated in the vicinity of the point (x). Thus plasma 4 is generated efficiently. Ions in the plasma become ion beams through the lead-out electrode 5. The ion beams 6 enter into the mass analyzing chamber 5 through an orifice 15. A voltage U+Vsin omegat, in which AC is superimposed on DC, is applied to the coils of the electromagnets of the quadrupole parts of the mass spectrometer. the ions of the desired mass are taken out through an orifice 16 by changing the AC voltage in said voltage.

Filed: 1982-08-31
Abstract: PURPOSE:To cut a groove into a constant depth from the edge of a flat plate regardless of the change of the plate size, when the groove is cut at the edge of a square wooden plate. CONSTITUTION:A cutting edge 16 with freedom in Y direction changed minutely its position by following a quidance plate 14. The guidance plate 14 bridged between quidance shafts 10 and 11 in Y direction, is shifted to the position in Y direction, while being controlled by elastic screw bodies 15. The distance D between the center of a guidance roller 17 and the cutting edge 16 is set up. The mechanism is so designed that the value obtained by taking off the radius- value of the guidance-roller 17 from this value D, is caused to be equal to the half of the depth (d) of a groove 2, i.e. the half of the cutting locus-circle of the cutting edge 16 of a rooter bit etc. Hence, the shape-change or the size- change in Y direction of a flat plate, are absorbed and the groove 2 is exactly machined.
