Title: Multi-room type air conditioner
Inventor: SUZUKI HIROSHI
IPC: F24F11/02
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To eliminate unnecessary cooling/warming by increasing the output from an inverter control compressor in response to increase of a load and performing forced servo operation required only for preventing occurrence of a harmful phenomenon, e.g. liquid back. SOLUTION: When a constant speed compressor 32 is started after starting an inverter control compressor 23, the constant speed compressor 32 is prevented from being overloaded by an extra load on the high pressure side of the inverter control compressor 23. When other indoor units 31 -3n are previously set with a forced thermo operation mode, forced thermo operation does not take place in the indoor units 31 -3n . Consequently, the indoor units 31 -3n are prevented from delivering a forced thermo operation command individually and the forced thermo operation can be limited to minimum time necessary for avoiding a harmful phenomenon, e.g. liquid back.

Title: Regenerating operation limiting device for motor
Inventor: FUKUMOTO NOBORU
IPC: H02M7/757
Filed: 1989-10-05
Abstract: PURPOSE:To prevent the fusing of a fuse as well as the breakage of a thyristor by a method wherein chances, in which a thyristor circuit becomes regenerative operation, are reduced by switching a reverse side thyristor bridge upon regenerative operation. CONSTITUTION:When a speed difference is changed into positive or negative, the polarity of a current command is changed into positive or negative and a positive side pulse output is outputted when said polarity is negative while a negative side pulse output is outputted when said polarity is positive. When a regenerative control signal 11 is inputted in this case, switching is precluded by a preferential circuit even when a switching condition into regenerative operation or the current command has become positive. When the output of the preferential circuit 4 is eliminated by a switching sensibility setter 12, the condition of driving operation side is retained preferentially whereby the control is stabilized. According to this method, the fusing of a fuse or the breakage of a thyristor in a thyristor bridge circuit due to the short-circuit of a motor driving circuit can be prevented.

Title: Semiconductor array having high output and high beam properties
Inventor: DAN BOOTEZU
IPC: H01S3/06
Filed: 1989-10-06
Abstract: PURPOSE: To enable a laser array to operate at a high output level by a method wherein a talbot distance is used combining it with a few means which are inside an array structure and restrain the laser array from operating out of phase in an array mode. CONSTITUTION: A first array 10 of a semiconductor waveguide and a second array 12 of a semiconductor waveguide are separated from each other by a non-laterally guided region 14 with a width which is nearly multiples of half a talbot distance. The elements of the array 10 are arranged in line with the intermediate element region of the second array 12, so that it is advantageous that a laser array operates in a basic mode or the same position array mode. Provided that one of the arrays 10 and 20 operates in the same phase or in a basic array mode, the emission of the array is transmitted passing through the diffusion region 14 and recombined at an intermediate point in a region between the initial emission laser elements.  The emission out of phase in a mode is recombined at a position distant in the same lateral direction with the emission array and efficiently restrained by a spatial filter effect obtained by selecting the lateral positions of the two arrays.

Title: Manufacture of superconductive coil
Inventor: MITSUI HISAYASU
IPC: A61B10/00
Filed: 1986-11-06
Abstract: PURPOSE:To enable superconductors to be solidly supported and a quenching current to be increased, by inserting packings of release materials beforehand into gaps serving as channels of coolants and forming a coil and next impregnating/filling this coil with resin and finelly extracting the packings. CONSTITUTION:Superconductors 1 are wound in multiple numbers in a supporting frame 3 which is made of high-strength non-magnetic metal such as stainless steel or fiber reinforced plastics such as an epoxy glass laminated plate and in which packings 8 of release materials, that is, rods of polytetrafluoroethylene are inserted into parts serving as channels for liquid helium of a coolant. An epoxy resin constituent is impregnated and hardened by a vacuum pressing method. when the packings 8 are removed after hardening, gaps 7 serving as channels for the coolant are formed. Since all gaps 11 are buried with epoxy resin, the superconductors 1 never move during the conduction of the coil. When liquid helium is made to flow, the superconductors are fully cooled and so a quenching current can be increased.
