Title: Boat for evaporation
Inventor: SAWADA AKIRA
IPC: C23C14/26
Filed: 1980-02-19
Abstract: PURPOSE:To equalize a thickness and quality of an evaporation coating, in the evaporating boat formed by a boat main body, an intermediate plate and a top lid, by thickening a thickness of the top lid thicker than that of the boat main body. CONSTITUTION:The evaporating boat for subjecting a sublimable substance to the evaporation is formed from the boat main body 1, the intermediate plate 3 and the top lid 2. To the top lid 2 and the intermediate plate 3, openings 2a and 3a which are not coincided to an upper and a lower directions are formed and, in a recessed part of the main body 1, an evaporating substance 4 is received. In this case, by adjusting the thickness of the top lid 2 to 1.5-3 times that of the boat main body 1, in evaporating said substance 4 by passing current to the boat, because electroconductivity of the top lid 2 becomes well and temp. rise of said top lid 2 itself becomes higher, said evaporating substance is not coagulated at the opening part 2a and a constant amount of the evaporating substance is always evaporated from said opening part 2a because a size of said opening part 2a does not become smaller. Therefore, a constant evaporating operation is always carried out stably.

Title: Self-diagnosis system for microcomputer
Inventor: WATANABE MASAHIRO
IPC: G06F11/30
Filed: 1981-02-12
Abstract: PURPOSE:To improve the response to failures, by providing a shift register which inputs a pulse train having a period within a prescribed range as clock and a watchdog pulse as a reset signal. CONSTITUTION:If the period of a pulse train is longer than an interruption routine execution time and no failure takes place in the operation of a microcomputer, one time watchdog timer pulse is outputted in one period of pulse train. A shift register 2 is reset with this pulse to obtain a pulse output with the same period as that of the inputted pulse train for Q1 output (output of the 1st stage). A Qn output (output of the final stage) is kept at 0 and no alarm signal is outputted. On the other hand, a microcomputer 1 runs away and no watchdog timer pulse is outputted, then the Q1 output is kept at 1 and the Qn alarm  output 1 is outputted at the input of the (n-1)-th or the n-th pulse from the  start of runaway.

Title: Removing method for ammonia contained in fluid
Inventor: KAIHO ISAO
IPC: B01D15/04
Filed: 1978-02-24
Abstract: PURPOSE: To remove NH 3  contained in a fluid efficiently by use of easily producible, inexpensive resin, by bringing the fluid into contact with porous cation exchange resin made by cross-linking with divinylbenzene and containing SO 3 H group  or its salt, the divinyl-benzene having comparatively low degree of cross-linkage.  
     CONSTITUTION: A porous cation exchange resin of degree of cross-linkage 10W 20%, made by introducing a sulfon group to a copolymer manufactured pref. by cross-linking styrene with divinylbenzene, is packed in a column. A liq. to be analyzed by liq. chromatography is made to flow through the column to remove NH 3  contained in the liq. Since the cation exchange resin is of porous type, sulfonation time of the ST-divinylbenzene copolymer is reduced, the resin is produced easily and the price of an NH 3 -removing apparatus can be reduced. Because of porous type, the resin is polluted only to a comparatively low degree with high molecular substances such as dye stuff, and the resin has a long service time.

Abstract: PURPOSE:To check any deformation of a cylinder by forming an escape part getting away from a local contact with the rear end face of a sliding groove, in a rear surface in the sliding direction of a vane, in this rotary compressor equipped with a roller eccentrically rotating in the cylinder, and the vane coming into contact with this roller and partitioning off the cylinder inside into both the high and low pressure sides. CONSTITUTION:This rotary compressor 1 is made up of housing a rotary compressor part 3 being driven by an electric motor part in an enclosed case 2, and this compressor part 3 is equipped with a roller 11 being inserted into an eccentric part of a turning shaft 9 and eccentrically rotating in a cylinder 6, and a vane 12 coming into contact with this roller of its tip and thereby partitioning off an inner part of the cylinder 6 into both high and low pressure sides. In this case, a cut part 17 escaping from a local contact with the rear end face of a sliding groove 14 is formed in a rear surface in the sliding direction of the vane 12. Owing to the existence of this cut part 17, a collision with the rear end face of the sliding groove 14 of a cylinder block 5 is turned to a bump between two curved surfaces themselves for the purpose of easement, and thus any possible deformation in those of cylinder block 5, cylinder 6 and further sliding groove 14 is fairly reduced.

Title: Oozing type coating roller
Inventor: OKURA HIDESUKE
IPC: B05C17/025
Filed: 1995-01-12
Abstract: PURPOSE: To ooze a coating material approximately uniformly from the outside surface of a roller, to uniformly apply the coating material and to prevent clogging by forming the discharge holes of a discharge pipe by slender slits in an axial direction and forming the opening area of the discharge holes larger on the front end side of the discharge pipe than on the base part side. CONSTITUTION: A discharge pipe 14 is obtd. by forming right and left ends 14a, 14b of plastic materials to a cylinder, forming an intermediate part 14c to a hollow triangular pile shape and forming the discharge holes, i.e., slits 15, extending in an axial direction. The opening quantity of the discharge part of the discharge pipe 14 by the respective slits 15a to 15c increases gradually from the base part side where the pressure increases toward the front end part side where the pressure decreases. The coating material discharged from the discharge pipe 14 is, therefore, discharged approximately uniformly from the overall length of the discharge pipe 14. Eventually, the coating material is uniformly oozed from the outside surface of the main body 20b.  Since the respective slits 15a to 15c are formed slender in the axial direction, the clogging is substantially prevented even with the coating material of a high viscosity.
