Title: Plant alarm system
Inventor: TAKAHATA YOSHIAKI
IPC: F23G5/50
Filed: 1993-09-27
Abstract: PURPOSE:To issue a proper alarm by discriminating it that supervisory object data are not convergent within a permissible range. CONSTITUTION:A data supervisory means 20 receives outputs of a temperature sensor of a precipitator 12, an NOX sensor of a smoke chamber 9, and a steam pressure sensor of a waste heat boiler 10 and manages the operation of a plant automatically. When the means 20 detects it that the output of any sensor exceeds its upper limit and the same state is consecutive for a margin time decided by its characteristic, an avoidance operation confirmation means 21 confirms the presence of avoidance to prevent the occurrence of an accident. When no avoidance takes place, an alarm operating means 23 operates an alarm means 24. When the output of any sensor is below its lower limit, a tentative fault or a fault avoided automatically or manually does not result in issuing an immediate alarm and only when the fault continues further as the result of avoidance, an alarm is issued and no useless alarm is issued.

Title: Hollow body having strip part made of material in different color
Inventor: NAGAI SUMIO
IPC: B65D25/54
Filed: 1989-09-14
Abstract: PURPOSE:To make proof stress larger against internal and external pressures by providing a horizontal cross-sectional contour in the form of a wedge at the boundary faces between the wall constituting a strip part made of the material of different colors and an opaque plastic wall. CONSTITUTION:A cosmetic bottle 1 is composed of a bottle body 2 and a cap 3 and the bottle body 2 is provided with a strip-like viewing window 4 extending from the top to the bottom thereof. The viewing window 4 is provided with a cross section having wedge-shaped parts 5 and formed of transparent or semitransparent plastic and an opaque wall 6 is made of opaque plastic. Since a horizontal cross-sectional contour is shaped into the form of a wedge at the boundary faces between the wall of strip part 4 made of the material of different colors and the opaque plastic wall 6, their contact areas at the boundary faces become large. This not only makes the joint strength larger but also increases the proof stress against internal and external pressures.

Inventor: KAGEYAMA SHIGEMI
IPC: B01D29/01
Filed: 1994-09-07
Abstract: PURPOSE: To enhance solid-liquid separation capacity by repeatedly increasing and decreasing the pressure in the airtight chamber provided on the rear side of a screen provided under tension in an inclined state while allowing a raw material to be treated to flow down along the surface of the screen and forcibly squeezing out a liquid component while allowing air to always flow through the raw material to be treated. CONSTITUTION: When livestock excretion (raw material to be treated) 2 is treated, an airtight chamber 3 is alternately increased and decreased in pressure by a reciprocating mechanism 7 and air sucking operation is performed through a screen 1 provided under tension in an inclined state when pressure is reduced while air emitting operation is performed when pressure is increased. The raw material 2 to be treated is supplied to the start end of the screen 1 while these operations are repeated. The liquid component in the raw material 2 to be treated is squeezed out to the airtight chamber 3 by the air sucked into the airtight chamber 3 from the outside when the raw material 2 to be treated on the screen 1 is sucked.  At the time of the emission of air, air is allowed to flow through the screen from below to above and brought into contact with the raw material 2 to be treated to effectively perform aeration.

Title: Heat exchanger
Inventor: KAWAZOE MASANORI
IPC: F28D7/08
Filed: 1989-09-14
Abstract: PURPOSE:To enhance contact properties of heat transfer tubes with a cylindrical body side fluid to suppress formation of a surface state boundary layer, to improve heat transfer performance and to simplify a heat exchanger by axially forming a plurality of tube bundles knitted with many heat transfer tubes in a stripe state in a spirally twisting state. CONSTITUTION:Tube bundles 3 are formed by knitting many heat transfer tubes 2 in a stripe state, and disposed axially in a cylindrical body 1 in a spirally twisting state. Accordingly, first fluid passing through the body 1 flows along the spiral surfaces of the bundles 3 to become a turbulent flow, the tubes 2 become crossing the flowing direction of the first fluid, and the flow near the surfaces of the tubes 2 becomes turbulent. Thus, many vortexes are generated in the flow of the first fluid to prevent formation of a boundary layer on the surfaces of the tubes 2. Since the tubes 2 for forming the bundles 3 have relatively large gaps therebetween, the first fluid flow laterally and longitudinally between the tubes 2 to improve contact properties of the first fluid with the tubes 2.

Title: End structure of a fuel cell
Inventor: ROBIN JIEI GASURII
IPC: H01M8/24
Filed: 1990-09-10
Abstract: PURPOSE: To maintain the flat plane surface of the end structure of a fuel cell without allowing any thermal distortion by having flexibility even under a temporary temperature change produced during the action of a fuel cell under such a condition that a thin layer soft film transmits compression force to a cell stack sufficiently and uniformly. CONSTITUTION: A temporary temperature change is produced only on a film 16. Despite of the production of the temporary temperature changes, force is transmitted in a fuel cell continuously and uniformly via a semi-hard heat insulator. During action of the cell, in such a case where the central part of the fuel cell is actuated at a temperature higher than that at the outside end part, it can happen that the stack 12 of the fuel cell is expanded to a different width. A hard plate 20 receives this expansion so that some excessive force is applied in one direction and an insufficient force is applied in the other direction. This phenomenon enables sudden cut of connection of one partial position or permanent distortion of the total compressive partial position to cut the connection at that partial position.  By supporting the film 16 by means of an elastic semi- hard heat insulator, the film 16 is deformed as the fuel cell is distorted, sufficient force is to remain in the fuel cell.

IPC: G05B11/36
Filed: 1992-07-24
Abstract: PURPOSE:To obtain the feedback control method which can optionally adjust a frequency range wherein low sensitivity is obtained while the stability of a feedback control system without depending upon a model error. CONSTITUTION:The multiplicative model error E(s) between the transfer function matrix, Gp(s) of a controlled system and the transfer function matrix G(s) of a model is represented as G(s)E(s), and the number of unstable poles of Gp(s) and E(s) are equally set to (m). The desired frequency band which is set to low sensitivity is from a direct current to certain high frequency omegao. When the transfer matrix of a compensator 5 which can optionally be set is denoted as P(s)6 and G(s)P<-1>(s) is an expanded model 4, the multaiplicative error is P(s)E(s). Then P(s) 6 is set at omegao from a frequency band 0 so that the vector track of detP(s)E(s) centering on the origin of a complex plane does not rotates on the origin in a Gp(s) 3 stable state or rotates m/2 times counterclockwise on the origin. The expanded model G(s)P<-1>4 using this P(s) is regarded as the controlled system to constitute the feedback control system.
