Title: Negative resist material having sensitivity against ionizing radiation
Inventor: TAKAHASHI YOICHI
IPC: G03F7/20
Filed: 1984-10-23
Abstract: PURPOSE:To obtain the titled material having a high sensitivity and a good definition and antidryetching properties by incorporating to the titled material either a halogen contg. acylsubstd. polyvinyl phenol copolymer having a specific mol% of a constituting unit and a specific average mol.wt. or a mixture of the prescribed polymer and another polymer having a compatibility against said polymer. CONSTITUTION:The above described polymer comprises 30-80mol% of the constituting unit I shown by formula I and 5-70mol% of the constituting unit II shown by formula II and also consists of the halogen contg. acylsubstd. polyvinyl phenol copolymer having the average mol.wt. of 3,000-1,000,000, or the above described polymer comprises the mixture of the prescribed polymer and another polymer having a compatibility against said polymer. If the above described polymer contains <30mol% the unit I, the obtd. material has less sensitivity. While if said polymer contains >80mol% the unit I, the obtd. material depresses a bonding strength against a substrate. In the unit II, it is most preferable to use a polyvinyl phenol skeleton having a hydroxyl group at a para position. If the mol.wt.of the polymer is <10,000, it makes difficult to form the resist film. If the mol.wt. of the polymer is >1,000,000, the polymer is too high viscosity to coat the substrate.

Title: Back washing process of filtration device
Inventor: NEJIGAKI TATSUO
IPC: B01D61/00
Filed: 1985-10-08
Abstract: PURPOSE:To eliminate the necessity of back wash tank and back wash pump by back-washing the semi-permeable membrane of the module, which is one of a number of lines and is not filtrating at the moment, with the filtrate coming from some other line, effecting the automatic adjustment of pressure fluctuation and maintaining the pressure at the inlet of module constant. CONSTITUTION:The semi-permeable membrane modules 1,1' and 2,2' are divided into the lines more than one. With the automatic valves 8, 9 and 14 open and the automatic valves 10, 12, 13 and 16 closed, filtration is carried out by the module 1,1' only of the module rack A, and the filtrate is flowed reverse to the normal flow, i.e. from the filtrate supply tube 61 and 62 to the module 2,2' of module rack B to clean the clogging substance in the semi-permeable membrane. The filtrate used for cleaning is sent back to the circulating tank 4 through the second by-pass line 15 and the first by-pass line 11. After finishing the back wash of module rack B, the role of rack A is switched over to the rack B. At this time, the pressure rise at the inlet of module which stops circulating is checked with the censor 23, and the number of rotation of supplying pump 3 is lowered with the control unit to maintain the pressure at the inlet constant.

Title: Method of controlling inverter tower loading air conditioner
Inventor: URASHIMA HARUO
IPC: F25B1/00
Filed: 1987-09-09
Abstract: PURPOSE: To protect a bellows against damage by setting the upper limit opening of an electronic expansion valve and the lower limit of supercooling and increasing the operating frequency of a compressor by a specified amount when the limits are exceeded respectively thereby requiring installation of a liquid tank. CONSTITUTION: An air conditioner comprising an electronic expansion valve, an inverter control section, a compressor and a frequency control section enters into a control for increasing the command frequency to a compressor by (a) Hz when the cycle enters into insufficient refrigerant operation and the opening of the electronic expansion valve reaches an upper limit N0 . When the frequency is increased to t+a Hz, the quantity of refrigerant to be circulated is increased in the cycle and the condensation pressure is increased thus increasing the degree of supercooling of refrigerant SC in front of the expansion valve. The cycle is stabilized by sustaining the f+aHz state for a predetermined time. If the opening of the electronic expansion valve is still at the upper limit after t0 time later, the command frequency is preferably increased furthermore. When the detected degree of supercooling drops below a set level, the cycle is stabilized by increasing the degree of supercooling.
