Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To suppress variations in characteristic that result from torsion of a control shaft at the cylinder farthest from an actuator, in controlling at a time the rocking positions of the control rings of plural cylinders using a control shaft. SOLUTION: Cylindrical camshafts 44 split for individual cylinders are placed on the outer periphery of a drive shaft 41 which rotates in synchronization with an engine, and an annular disk 49 is placed between the first flange part 435 of each camshaft 44 and the second flange part 46 of the camshaft which is secured to the drive shaft 41. The annular disk 49 is held by a freely rocking control ring 50 and is connected to the ring 50 by a pair of pins 55, 56 which are engaged in engaging grooves. When a control shaft 59 is rotated by an actuator 61, the annular disk 49 is brought to an eccentric position by an eccentric cam 60, and the camshaft 44 is rotated at nonuniform speed, resulting in a variation in valve lift characteristic. The annular disk 49 of each cylinder is located on the side of the actuator 61 across the center of each cylinder.

Title: Circuit for preventing mis-deletion of memory
Inventor: SAKAI MISAKO
IPC: G11C16/02
Filed: 1994-11-17
Abstract: PURPOSE: To prevent a mis-deletion and to improve the reliability at the time of deleting data by controlling so that data is not deleted when it is discriminated that a command is inputted within a prescribed time. CONSTITUTION: A timer 52 discriminates the lapse of a prescribed time in which the last deletion command out of plural deletion command is inputted and deletion operation is finished. When an output of an AND circuit 61 and an LECLK signal outputted when data is prepared in a serial data register of a serial input/output circuit are supplied to a NAND circuit 62, a pulse signal J6B is outputted. A reset circuit 63 judges existence of input of data by the signal J6B outputted from the circuit 62, and generates reset signals of each section based on the signal J6B and outputs them. Therefore, when a command is inputted within the prescribed time, execution of deletion of data being written is interrupted, and mis-deletion by an erroneously inputted deletion command can be prevented.

Title: Method and apparatus for injection-molding using thermoplastic resin
Inventor: OGAWA NOBUO
IPC: B29C45/67
Filed: 1986-11-27
Abstract: PURPOSE:To make it possible to realize high speed continuous molding by a method wherein a new plate-shaped middle force is installed between a top and a bottom forces at the stage that thermoplastic resin filled in the middle force cures to some extent so as to perform the operation for removing resin molded item from the plate-shaped middle force, into which resin has been poured, is done in parallel to the operation for pouring resin in the new middle force. CONSTITUTION:A semiconductor lead frame 36 is pinched between an upper and a lower product plates 30 and 31. In addition, a runner plate 34 is laminated beneath the lower product plate 31 so as to form a plate-shaped middle force 3. The thermoplastic resin, which is poured out to the force, is filled through gates 35 into the cavities of the product plates 30 and 31 and cools down and cures. At the stage that the resin cures to some extent, the top force 1 and the bottom force 2 are parted from each other in order to remove the middle force 3 from and to install a middle force, the cavities of which are empty, to the forces 1 and 2. The removed middle force 3 is demolded at a separate workshop and prepared for next use. Accordingly, the curing time of item can be shortened to a far greater extent. Since the middle force is made to be detachable from the top and the bottom forces, one cycle of molding process can be shortened to a far greater extent, resulting in allowing to realize a high speed molding operation.

Patent JP-H03144684-A (JP)
Title: Image forming device
Inventor: ITSUKIDA MASAMI
IPC: G03G15/20
Filed: 1989-10-31
Abstract: PURPOSE:To prevent an excessive rise in the temperature of a heater lamp by directly applying the temperature of the heater lamp to a temperature fuse. CONSTITUTION:The temperature of the tube wall of the heater lamp 40 rises faster than that of the surface temperature of a roller 41. Since the temperature fuse 100, in contact with the heater lamp 40 directly, is heated at the temperature equal to that of the tube wall of the heater lamp 40, its temperature rises excessively before the surface temperature of the heat roller 41 reaches its melting temperature. When the temperature of the fuse 100 comes to equal to or above the temperature determined by its material, an organic compound in the temperature fuse 100 are fused. Accordingly the energization of the heater lamp 40 is shut off, and the surface temperature of the heat roller 41 is prevented from rising higher than that. Thus, an excessive rise in the temperature of the heater lamp can be prevented.

Title: Radio receiver
Inventor: ASAMI MASARU
IPC: H04B1/16
Filed: 1998-10-07
Abstract: PROBLEM TO BE SOLVED: To enable automatic switching to RDS (=FM broadcast) broadcasting the same radio program as the radio program of DAB (=digital audio broadcast) without any feeling of physical disorder when the reception state of the DAB(digital audio broadcast) becomes worse. SOLUTION: In view of differences in the FM modulation degree of RDS among broadcasting countries of RDS, the broadcasting country of a radio program is checked with FIG0/2 of DAB and the FM modulation degree is found from the broadcasting country. When the FM modulation degree is 75 kdev, the amplitude of a demodulated signal of RDS is lowered by 5 dB and then sent to a subsequent stage. Consequently, when the sound volume of the sound source is equal, the sound is outputted from a speaker 24 with the same sound volume with an FM modulation degree of 40 Kdev even if the FM modulation degree is 75 kdev.
