Abstract: PURPOSE: To enable a firm coated skin film with a good appearance to be formed with respect to the molded article by smoothing a resin orientation in the surface of the molded article by an injection compression molding method, simultaneously, carrying out molding while decreasing molding residual distortions, and further performing painting on the surface. CONSTITUTION: A molded article is made through an injection compression molding method by smoothing a resin orientation on the surface of the molded article, and also simultaneously made while decreasing molding residual distortions generated in the deflection part. Coating is carried out while preventing the adherence of a gas or a monomer in the flow end or a weld part and the like in the surface of the molded article. Herein, in the injection compression molding method, initially, the cavity space is made thicker in the order of 1-10mm than a molded body to be obtained finally, and a molded article is obtained in such a manner that the cavity space 4 is compressed to the desired thickness while injecting a molten resin 5 into the cavity or after the completion of injection.  A coating treatment is conducted after the molding, however, a firm coated skin film is obtained due to its uniformized adhesive strength.

Title: Emergency releasing apparatus for cassette gas cylinder
Inventor: KOYAMA MASAYA
IPC: F24C3/14
Filed: 1995-12-11
Abstract: PROBLEM TO BE SOLVED: To improve the safety by immediately releasing a cassette gas cylinder by forming the end of a control member for controlling the mounting motion of the cylinder on a governor in an emergency release allowing member for allowing the movement of the cylinder in the releasing direction from the governor. SOLUTION: A control plate (one example of integrating a control member and an emergency release allowing member at the end) 62 for rotating a vertical pin 61 as a center in the direction of an arrow D is mounted. The plate 62 is automatically rotated in the direction of the arrow D by the interference of a positioning piece 63 attached to the end of the end part 55c of a second lever, but is impossible to rotate in the opposite direction to the arrow D on the contact position with the piece 63. Since the plate 62 is mounted rotatably around the pin 61, a plate 66 to be controlled pushes to retract the plate 62 and returns in the opposite direction to an arrow E. Accordingly, at the time of emergency, a cassette gas cylinder is instantaneously released from a governor to make it possible to shut off the supply of gas.

Title: System for managing electronic mail system
Inventor: TANAKA KEIZO
IPC: H04L12/58
Filed: 1991-12-06
Abstract: PURPOSE:To reduce the retrieval time when a reception mail list is referenced and to facilitate the management of a mail by managing a delivered mail and an undelivered mail with separate files. CONSTITUTION:A main transmission distribution procedure 4 stores mail management information C to a storage mail management file 2 by sending a mail M and a mail text B is stored in a mail content file 3. When a time reaches a delivery time of the mail M, the procedure 4 monitoring the delivery time reads the information C from the file 2 and stores it in a delivery mail management file 1 and deletes the information C from the file 2. Thus, when the user Y references a received mail list, a reception mail reference procedure 5 retrieves the file 1. Thus, the retrieval time for referencing the received mail list is reduced and the mail management is facilitated.

Title: Nonaqueous battery
Inventor: HIRANO TOMIO
IPC: H01M4/587
Filed: 1987-12-22
Abstract: PURPOSE:To make battery assembly work under the condition of inert gas atmosphere unnecessary and facilitate the work by using fiber-state alkaline metal graphite interlayer compound instead of alkaline metal as a cathode activating substance. CONSTITUTION:A cathode activating substance is added with graphite-like carbon fibers and alkaline metal, pressed, annealed in an inert gas atmosphere and made into an interlayer compound such as a plate-shaped electrode. At this time, it is preferable that the diameter of the graphite-like carbon fiber is 0.1-3mum and its carbon layer surface is disposed in a cone or pyramid shape with a tilting angle of 2-45 deg. with respect to the fiber axis. If the cathode activating substance obtained in this way is used instead of the cathode 2 of a battery using an alkaline metal, the alkaline metal turns again into the graphite interlayer compound at the time of charging. This facilitates manufacture without causing arborescent metallic crystals on the electrode surface and not specifically under the condition of inert gas atmosphere.
