Title: Folding type door mirror
Inventor: WAKIMOTO FUMIYOSHI
IPC: B60R1/074
Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To secure the rigidity of the pivot of a bracket, by making only the position to conform with the projection of a base at the rotation stopping position of a mirror main body depending on a stopping position prescribing means, in a projection receiving groove recessed in the bracket for assembling the mirror main body, deeper than the other parts. SOLUTION: In a base plate 14, a projection 18 projecting to the groove 17 in the peripheral direction of a bracket 11 is provided. By abutting this projection 18 to the ends of the groove 17 in the peripheral direction, the relative rotation allowable scope of the bracket 11 and the base plate 14, that is, of a mirror main body and a base, is prescribed. The stopping position of a mirror in the groove 17 in the peripheral direction, that is, the part 17a corresponding to the position where a recess 16 rides on a steel ball 15, and the bracket 11 is lowered, is made deeper (the thickness is made thinner). However, the section the mirror main body rotates, that is, the section that the bracket 11 rides on the steel ball 15, is made thinner as the amount the bracket 11 is raised, so as to increase the thickness.  Consequently, the rigidity reduction of the peripheral part is suppressed at the minimum.

Title: Viscosity-joint oil filling method
Inventor: HIRAI SEIICHI
IPC: F16D35/00
Filed: 1990-08-01
Abstract: PURPOSE:To keep a proper amount in filling by measuring the dead weight of a viscosity joint before filling oil therein and the weight after filling to find a difference between these weights and calculating an average real filling amount per pulse in accordance with the difference to obtain a set pulse value in filling thereafter. CONSTITUTION:The dry weight of a viscosity joint which has been assembled, and then the capacity of a fluid room is measured by a capacity measurement device. At this time, the preset filling amount of oil to obtain a desired volume rate is calculated to find a set pulse value in accordance with the amount of oil per pulse. For the set pulse value, the real filling amount (cc) of the viscosity joint which has been already filled is divided by set pulse at that time to find a pulse coefficient (an average real filling amount per pulse), and the set filling amount is divided by the pulse coefficient to find the set pulse value. On this account, the pulse coefficient includes, in nature, air addition amount in filling, therefore showing that the air addition is allowed for the viscosity joint in filling thereafter.

Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To enable the effective recovering of ε-caprolactam and at the same time the recycling of a non-melting material such as glass fiber by separating the non-melting material from nylon 6 products containing the non-melting material. SOLUTION: Nylon 6 products containing a non-melting material (e.g. glass fiber) is depolymerized, then the reaction mixture of depolymerization is discharged into water, and subsequently the non-melting material is separated and recovered. The depolymerization is preferably performed according to dry depolymerization at a depolymerization temperature of <=280 deg.C. The amount of water into which the reaction mixture of depolymerization is discharged may be as far as it can dissolve the ε-caprolactam in the reaction mixture of depolymerization, and it is preferably 0.1-50 times the reaction mixture of depolymerization by volume. According to this process, the reaction mixture of depolymerization is converted to an ε-caprolactam aqueous solution by discharging it into water to lower the viscosity with the result that the non-melting material becomes easily separable.  Further, not only ε-caprolactam but also the non-melting material becomes recyclable.

Title: Positron ct apparatus
Inventor: OKAJIMA KENICHI
IPC: G01T1/29
Filed: 1981-12-22
Abstract: PURPOSE:To reduce the missing of simultaneous counting otherwise causing non-linearity in the  accidental simultaneous counting rate and the counting rate of a positron CT apparatus as  probable noise component by decreasing a part of a dissipated gamma ray from the perimeter of a  view having position information of a ray source with a member for absorbing gamma ray with a  larger wavelength than it inserted between scintillators. CONSTITUTION:The chart shows changes in the simultaneous counting rate when the length of  a tungsten plate is varied with a gamma ray incidence angle theta=25 deg. for example, employing tungsten for a gamma ray absorbing member. The simultaneous counting rate was reduced by about  10% when the tungsten plte was set at the reference length +4mm. in the length and 1mm. in the  thickness and about 40% when the length of the tungsten plate exceeds the reference length +12mm. as compared with the case without the tungsten plate. The reference length +12mm. is  found to be the optimum length of the tungsten plate. When the length of the tungsten plate  was less than the reference length +4mm., the reduction rate in the simultaneous counting rate  is small in the perimeter of the view. No substantial advantage was noted. The tungsten plate  proved appropriate when it was 0.5-2mm. in the thickness and projected by more than 4mm. from the surface of scintillators in the length. Even in the case of a positron CT, the projection of  the tungsten plate by more than 4mm. from the surface of the scintillators is expected to yield  an effect of reducing the simultaneous counting rate in the perimeter of the view.
