Title: High-frequency heating device
Inventor: HAYAMIZU KATSUAKI
IPC: H05B6/68
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To adequately heat an object to be heated, irrespective of the state of the object to be heated. SOLUTION: A microwave oven is equipped with a wave guide 10, a magnetron 16 for emitting microwaves, a magnetron antenna 15 projecting within the wave guide 10, and a radiating antenna 13 for enlarging the expansion of the microwave. The radiating antenna 13 is held by an antenna support member 2 such that its angle can be changed. When an object to be heated is frozen, because there is much ice but little water that absorbs microwaves, the angle of the radiating antenna 13 is set at 90 deg. with respect to the magnetron antenna 15, in order to irradiate the microwave to the whole span of a heating chamber.  If the object to be heated is relatively large in height, the radiating antenna 13 is directed upward in order to have the microwave irradiated towards the upper part of the heating chamber, and, if the object to be heated is relatively low in state, the radiating antenna 13 is directed downward in order to have the microwave irradiated towards the lower part of the heating chamber.

Title: Method and apparatus for controlling pulse width modulation of inverter
Inventor: YAMAI HIROYUKI
IPC: H02M7/48
Filed: 1991-04-10
Abstract: PURPOSE:To provide very precise PWM control without using a high- performance processor or special timer by using the interruption timer function or software timer function of a microcomputer according which is larger, the specified time not shorter than the interruption system conversion time or pulse width. CONSTITUTION:A one-chip microcomputer 8 makes the difference between the pulse width which was so calculated as to be used for PWM control of an inverter 3 and the time which corresponds to the specified time not shorter than the interruption system conversion time which is the time till the interruption handling is started after an interrupt signal is given. When the microcomputer 8 discriminates that the pulse width is larger, it sets a difference between the calculated pulse width and the value which corresponds to the interruption system conversion time in an interruption timer 8g. When the microcomputer 8 discriminates that the pulse width is not larger, it sets the calculated pulse width in a software timer 8h. Consequently, a very precise pulse width modulation control is provided without a special timer function.

Title: Safety door locking device of injection molding machine
Inventor: CHIRI EIJI
IPC: B22D17/26
Filed: 1990-03-27
Abstract: PURPOSE:To enable locking to be effected positively and also enable the opening of a safety door to be performed promptly by providing a permanent magnet on the stationary plate side end part of the safety door, and providing a direct current electromagnet on the side end part of the safety door. CONSTITUTION:A safety door 1 is closed in accordance with a molding cycle. Prior to the complete closing of the safety door 1, it strikes the tip coil spring 6 of a locking rod 5 and thus the shocks in the closing period is decreased. At the same time of closing the safety door 1, the signal of a limit switch 14 is inputted into a sequencer 13 and then a switch 12 is closed by outputting a signal (c), wherein a stopper 8 raised by a locking direct current electromagnet 7 and the tip part thereof engages the engaging projection 5a of the locking rod 5. Simultaneously, the sequencer 13 outputs a signal (a) and a switch 10 closes so that a direct current electromagnet 4 is magnetically attracted to a permanent magnet 2. Thus, the safety door 1 is dually locked by the fixation of the stopper 8 and magnetic attraction. At the time of opening the safety door 1, when a safety door releasing signal is inputted into the sequencer 13, the necessary procedures and forces for opening are reduced because the safety door 1 opens at a predetermined distance.

Title: Spouting runner in bottom pouring method
Inventor: ASANO IWAO
IPC: B22C9/08
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To prevent the development of bare molten metal surface without lowering casting speed and to reduce the consumption of an oxidation inhibitor by forming the inner diameter at the tip part of a spouting runner to larger than the inner diameter of a main body. SOLUTION: Spouting pressure is dispersed by forming the tip part diameter D1 of the runner 40 to >=1.1 times of the main body part diameter D2 and also, the molten metal surface is stabilized by lowering the flowing speed of the molten metal rising at the center part, and the development of cold shot is restrained and the entrapment of the oxidation inhibitor is reduced. Therefore, since the development of the bare molten metal is prevented by stabilizing the molten metal surface without lowering the casting speed, the oxidation inhibitor is scarcely needed to use and is sufficient in only the necessary quantity to cover the molten metal surface. Further, since the molten metal rising is stabilized and the molten metal is formed as laminated flow state to reduce the entrapment of the oxidation inhibitor into the molten metal, the quality of a produced steel ingot, etc., is improved.
