Title: Removal of trace halogen contained in epoxy resin
Inventor: NAKATSUKA RIYUUZOU
IPC: C08G85/00
Filed: 1982-04-05
Abstract: PURPOSE:To lower the halogen content of an epoxy resin effectively, by reacting the resin prepared from an epihalohydrin with an organic acid silver salt in an amount nearly equivalent to the halogen groups contained in trace in the epoxy resin and then filtering off the formed precipitate. CONSTITUTION:An epoxy resin of a polyglycidyl ether type is prepared by reacting an epihalohydrin (e.g., epichlorohydrin) with a polyhydricphenol (e.g., bisphenol A) in the presence of an alkali. Then, the total amount of hydrolyzable and nonhydrolyzable halogen groups contained in the produced epoxy resin is measured, for example, by a flask combustion method. Then, the epoxy resin is purified by dissolving, if necessary, the resin in an organic solvent (e.g., toluene) and reacting it with an organic acid silver salt (e.g., silver nitrate, silver lactate) in an amount nearly equivalent to the halogen groups, and filtering off the formed precipitate after completion of the reaction.

Title: Hydraulic pressure control device for anti-skid device
Inventor: YOSHIDA TOSHINORI
IPC: B60T8/1766
Filed: 1985-03-18
Abstract: PURPOSE:To reliably prevent locking of a rear wheel with a compact device, by opening a cut-off valve to hinder a hydraulic pressure in a wheel cylinder of a rear wheel from being increased over a predetermined value when a hydraulic pressure in a wheel cylinder of a front wheel is abnormally increased to exceed a predetermined value. CONSTITUTION:When coefficient of friction between a road surface and a right wheel is smaller than that between a road surface and a left wheel, and a right front wheel is locked, a liquid in a wheel cylinder of the right front wheel is discharged to a reservoir. Therefore, hydraulic pressures in output chambers 79a and 80a in a pressure selecting valve device B are decreased to rightwardly move a piston 62. As a result, a left poppet valve member 72b is seated on a valve seat 75b, and a right valve member 72a is further moved away from a valve seat 74a. Accordingly, left output chambers 79b and 80b are cut off to stop supply of the liquid to a wheel cylinder of a right rear wheel. When the locking of the right front wheel is released, the piston 62 is leftwardly moved to release the cut-off condition and increase a braking force of the right rear wheel. Thus, a braking pressure of a rear wheel is controlled by a braking pressure of a front wheel on the same side to thereby prevent locking.

Title: Semiconductor laser device
Inventor: UMEDA JIYUNICHI
IPC: H01S5/40
Filed: 1981-04-15
Abstract: PURPOSE: To obtain a large power multiple point light emission type laser by locally forming a structure producing composite refractive index difference for the laser light in parallel or in matrix state along the laser oscillation direction in the vicinity of a plane of an active layer, restricting the light emission of the respective points in lateral basic mode oscillation, thereby photocoupling the mutual light emissions.  
     CONSTITUTION: An n type Ga 1- SAlS2(s≥x+0.3)Ga 1- XAl x As active layer 3, a p type Ga 1-y Al y As 4 (y=x+0.4), and rectangular or insular n type or p type Ga 1-z Al z As 5(0≤z<x) parallel with the laser oscillation direction are formed on an n type GaAs 1, thereby absorbing light. The period of rectangular film 5 is approx. 10μm in such a manner that the period/width is selected to 3∼10. A cap layer 7, a Cr-Au current injection layer 8, and an Au-Ge electrode 9 on a substrate 1 are formed, and are cleaved vertically to the advancing direction of the laser light. Composite refractive index differences are formed in combination with local refractive index difference, light absorbing difference or photoamplifying gain difference or in combination of them, a laser oscillation is thus performed locally, but since the interval of the light emitting regions is narrow, the lights are mutually interfered, therby photocoupling, and the oscillation of the local light emission is maintained in the same wavelength at the prescribed phase relation.

Title: Alarm hold circuit
Inventor: AKEYA MIKIJI
IPC: G08B23/00
Filed: 1991-02-28
Abstract: PURPOSE:To fix the alarm holding time of an alarm hold circuit which holds alarms. CONSTITUTION:When a live alarm (b) becomes 'H' (alarming state), an n-bit binary counter 1 is initialized. Another n-bit binary counter 2 starts count-up from the moment the live alarm (b) becomes 'L' and i-output of the counter 2 changes from 'L' to 'H' when the counter 2 counts a set value (i). As a result, a signal from an inverter gate 3, namely, an alarm output (c) changes from 'H' to 'L'. Since an AND gate 1 inhibits a clock (a) based on the alarm output (c), the counter 2 fixes the i-output at 'H' state.

Title: Magnetic head
IPC: G11B5/23
Filed: 1992-03-13
Abstract: PURPOSE:To prevent the contour effect by forming metal magnetic films near the magnetic gap in a chevron form with the magnetic gap as the summit of the chevron. CONSTITUTION:Half cores 23 have a winding hole 26 in the joined part and an annular metal magnetic film 24 is formed around the hole 26 in a manner that a part of the magnetic film 24 is exposed on the medium-facing surface 22 to form the magnetic gap. The metal magnetic film is formed in a chevron shape with the magnetic gap as the summit of the chevron spreading downward in the cross section perpendicular to the gap width of the metal magnetic film 24. The metal magnetic film 24 is formed in a chevron form with loose slopes near the magnetic gap, which is looser than in a conventional magnetic head. This realizes such a traveling state of a magnetic tape for recording and reproducing that the tape approaches softly, touches the gap, and then softly goes away. Thus, the magnetic circuit is made small in size and can be used for high frequencies.

Title: Pneumatic tire
Inventor: OZAWA OSAMU
IPC: C08L67/02
Filed: 1995-03-15
Abstract: PURPOSE: To make a tire lightweight by constituting an air transmission preventing layer by means of a thin film of a resin component including the specified amount of thermoplastic polyester elastomer formed of a block copolymer of a polybutylene terephthalate and polyoxyalkylene diimide diacid having the specified weight ratio. CONSTITUTION: An air transmission preventing layer is constituted of a thin film of a resin component including thermoplastic polyester elastomer of 20wt.% or more formed of a block copolymer of polybutylene terephthalate and polyoxyalkylene diimide diacid, in which the weight composition ratio of polybutylene terephthalate and polyoxyalkylene diimide diacid is 85 to 15 or more. When the weight ratio exceeds the ratio of 85 to 15, riding comfort of a manufactured tire is deteriorated because the Young's modulus of the resin component is excessively increased, and it is not desirable. When the mix ratio of thermoplastic polyester elastomer is 20wt.% or less, the air transmitting resistance of the resin component is decreased, and the function as the air transmission preventing layer is eliminated.

Title: Flux-cored welding wire having mesh
Inventor: KASHIMURA TOSHISADA
IPC: B23K35/368
Filed: 1987-03-11
Abstract: PURPOSE:To improve a corrosion preventive effect and to reduce the corrosion preventing cost by allowing to contain a volatile corrosion inhibitor in flux of a flux-cored welding wire having a mesh. CONSTITUTION:A sheet steel strip is bent and the flux is filled in an opening part and the sheet steel strip is closed to form the flux cored welding wire having the mesh. At this time, a gap of <=0.02mm is formed on the mesh. Further, the volatile corrosion inhibitor such as dicyclohexyl ammonium nitrite (DICHAN), etc., is added and mixed in the rate of about 0.003-0.5g per 10kg weight of the wire in the flux. Since there is the gap of the sheet steel strip, the vaporizing speed of the corrosion prevention is restrained. By this method, since the corrosion preventive effect of the corrosion inhibitor is maintained for many hours, the corrosion preventive effect is improved and the corrosion preventing cost is reduced.
