Title: Door structure
Inventor: YAMANAKA RYOICHI
IPC: E06B3/36
Filed: 1999-06-16
Abstract: PROBLEM TO BE SOLVED: To provide a door structure which can prevent a door from biting into a door opening when the door is tilted and prevent a latch from being caught in a striker and obstructing opening of the door. SOLUTION: Door stops 15, 16 and the end faces of a door 14 abutting the door stops 15, 16 are tapered so that a door opening widens in the opening direction of the door 14, thus preventing the door 14 from biting into the door opening and becoming unopenable when inclined. When the door latch 19 bites into a door striker 20 and the door 20 cannot be opened, an engaging piece is unlocked from the frame of the striker 20 upon application of a force to the door 14, thus releasing the door latch 19 from a biting state.

Title: High kneading screw
Inventor: FUJIWARA YOTARO
IPC: B29C48/53
Filed: 1990-06-29
Abstract: PURPOSE:To improve remarkably the kneading property of a screw by a method in which the depth of resin-feeding screw groove and the depth of the screw groove of semimolten plasticized resin are gradually reduced continuously, and the depth of resin-feeding screw groove is made deeper than the depth of the screw groove of semimolten plasticized resin and the depth of the screw groove of the discharging side of molten plasticized resin. CONSTITUTION:The solid resin moved from feeding part FZ is damper up at a first auxiliary flight beta1, and with the rotation of a screw 1, a molten film is formed between a cylinder 5 and the solid resin by its strong shearing action, and then the fusion of the surface of the solid resin is quickly accelerated by the shearing force of the molten film. Further, since the gap Z2 between the cylinder barrel 5 and a second auxiliary flight beta2 is less than the gap Z1 between the cylinder barrel and the first auxiliary flight beta1 when the resin gets over the second auxiliary flight beta2, and further the screw groove 3 of semimolten plasticized resin and the screw groove 4 of the discharging side are shallow, the molten resin which gets over the first auxiliary flight beta1 and is moved receives more shearing energy by the rotation of the screw 1, and the resin is perfectly melted, whereby kneading property is improved.

Abstract: PURPOSE:To check the transmission of a frame asynchronization alarm to following equipments by sending a correct frame synchronizing signal pattern and an inserted auxiliary signal to the following equipments even if frame asynchronization is generated due to a receiving trouble. CONSTITUTION:An auxiliary signal extracting/inserting circuit 3 extracts an auxiliary signal pattern as an auxiliary signal 105 from a receiving reproduced signal 102 on the basis of a frame synchronizing signal 103. A frame synchronizing signal generating circuit 5 generates a signal having the same pattern as that of the signal 103 synchronously with the output of an oscillator 4 and a scramble signal generating circuit 6 similarly generates a scramble signal. A multiplexing circuit 7 multiplexes three inputs. Since a switching circuit 8 outputs a repeating signal 107 when frame synchronization is normal or outputs the output of the circuit 7 when frame asynchronization is generated, an always correct frame synchronizing signal pattern is included in a transmitting modulation signal 108 which is the output of a modulator 9 independently of normal or abnormal frame synchronization and an auxiliary signal 106 from the outside is also correctly inserted.
