Title: Accumulation and regeneration of power by means of refrigerant
Inventor: MATSUMURA TOMITAKA
IPC: F01K3/00
Filed: 1981-05-06
Abstract: PURPOSE:To realize power regeneration with safety and certainty when necessary by compressing refrigerant steam by means of power to accumulate it as heat energy so that the power may be regenerated in form of the pressure of refrigerant steam. CONSTITUTION:Refrigerant stesm 4 is compressed and liquefied by means of a compressor 5 utilizing power. The power is then accumulated as heat energy. When regeneration of power is required, it is obtained by means of a motor 6 (one which makes an action reverse to the compressor 5) utilizing pressure of compressed refrigerant steam 4. This shortens a time for accmulating power and enables reduction in size and weight of the unit. Further, power cumulation capacity is increased and execution of the safety measures is easier because most of them are related to pressure. Since operation control is easy to perform because it can be done by means of valve only, and production cost is rather low for its cumulation capacity, the device can stand almost permanent use.

Title: Heating cooker
Inventor: IKEDA SHUJI
IPC: F24C15/20
Filed: 1990-03-19
Abstract: PURPOSE:To prevent users from receiving an unpleasant feeling from the exhaust air coming out of a heating chamber and from the danger of suffering a burn when he opens a door after heating for cooking is finished by a method wherein a forced exhaust device for forcibly discharging air from a heating chamber and an exhaust purification device provided in a flue for purifying exhaust air by an exhaust purification catalyst are made to operate for a predetermined time even after heating for cooking is finished. CONSTITUTION:When food 2 in a heating chamber is heated for cooking, the exhaust air 5 containing soot or the like produced from the food 2 is forcibly discharged by a sirocco fan 6 from inside of the heating chamber 1 through a flue 7 to the outside of a main body 9. When the exhaust air 5 passes through an exhaust purification catalyst 8, organic matter in the exhaust air is thereby decomposed and oxidized for purification. Even after cooking is finished, the sirocco fan 6 is operated to pass the exhaust air 5 through the exhaust purification catalyst 8 for purification, after which it is discharged to the outside of the main body 9. As a result, the inside of the heating chamber 1 is made free from the soot or the like and, even when the user opens a door 10 to take out the heated food 2, he does not receive any unpleasant feeling therefrom and also the indoor air and the heating chamber can be kept clean. Moreover, the temperature of the exhaust air 5 in the heating chamber 1 falls and there is no concern that it may cause a burn to the user.

CONSTITUTION: A mechanical adapter member 2 and a pipe member 3 are installed at an end portion of a rectangular cavity waveguide 1, that is connected to a microwave introducing vacuum member, i.e., a plasma chamber 4; the member 3 is connected to a microwave propagation path (not shown), and is exposed to atmospheric pressure. In between a flange 12 of the member 2 and a flange 13 of the chamber 4, a seal ring 14 playing a role as a harmetic seal against outside environment is installed; in the other flange 7 of the member 2, a window 15 made of quartz, ceramics, etc., which can pass ultra-violet waves is formed. As attaching means to connect the window 15 to the member 2, high-quality silicon is used so as to ensure low loss, durability to vacuum up to 10<-8> millibar, stability at 150 deg.C and elasticity. In this case, the diameter of the window 15 is greater than that of the wave guide 1, which allows its edge to bite into a recess 16 formed in the waveguide 1.

A part of the magnetic flux flows to the opposite side to the gap 6.3 to form a closed magnetic path, and another part of the magnetic flux goes toward a vertical recording medium 2.1. In addition, a magnetic core 8.1 is provided at the position near the gap 6.3, and the magnetic fluxes shown by the dotted lines are generated by a coil 8.2 wound around the core 8.1. As a result, the quantity of leakage toward the medium 2.1 can be increased for the magnetic flux generated at the gap 6.3.

IPC: B66B13/14
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To protect a user and reduce the impact of a door by setting the door opening and closing speed command value to a prescribed value or less when the motor speed detected value is saturated to a maximum value in the output of a motor voltage command value according to the deviation between the rotating speed detected value of a door driving motor and the door opening and closing speed command value.

Further, it determined the difference between this motor current command and the actual motor current value by a current detector 31 and calculates the voltage command proportional to this difference to control a door motor 12 through a main circuit 9. When a force as hinders the door opening and closing operating is added to increase the difference between the speed command and the speed signal, the torque command is increased, and the speed signal reaches a maximum value, the speed command is reduced for a prescribed time to prevent the excessive acceleration by overshoot of door opening and closing control.
