Title: Device for coupling and holding low temperature liquid pipe
Inventor: SAKURAI TAMIO
IPC: F16L53/00
Filed: 1992-10-07
Abstract: PURPOSE:To smoothly carry out natural convection of low temperature liquid circulating through a riser pipe provided in a pipe line connecting between a low temperature liquid source and a supply destination, by providing a rectifier for preventing an ascending stream and a descending stream from colliding with each other, in the riser pipe. CONSTITUTION:A riser pipe 4 extending in a vertical Z-axial direction and connecting an upper pipe line 2 connected to a low temperature liquid source and extending in a horizontal x-axial direction with a lower pipe line 3 for feeding low temperature liquid to a destination and extending in a horizontally y-axis direction is provided in its intermediate part with a twisted plate (rectifying plate) 5 having a predetermined height. The angle of the twisted plate 5 continuously varies from the lower to upper ends 5t thereof, circumferentially of the riser pipe 4. Accordingly, an ascending stream of liquid whose temperature is raised at a supply designation end and a descending stream directly from the low temperature liquid source are prevented from colliding with each other in the pipe line, and accordingly, these stream may flow smoothly so as to ensure smooth natural convection, thereby it is possible to efficiently circulate the low temperature liquid.

Title: Production of poly-3-hydroxyalkanoic acid
Inventor: TAGUCHI KAZUNORI
IPC: C12R1/19
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To produce a poly-3-hydroxyalkanoic acid usable for alternative plastics by introducing a polymerase gene of the poly-3-hydroxyalkanoic acid, and a fatty acid synthetase gene to a host microorganism, proliferating the host microorganism, and isolating and purifying the product. SOLUTION: A polymerase gene of a poly-3-hydroxyalkanoic acid is incorporated into a wide host range expression vector pJRDTrc1 for a Gram-negative bacterium to construct the expression vector of the polymerase gene of the poly-3-hydroxyalkanoic, acid. On the other hand, a fatty acid synthetase gene derived from Escherichia coli is incorporated into a vector pBluescriptII-KS(+) for expression, to construct an expression vector of the fatty acid synthetase gene. These expression vectors are transduced to a host microorganism such as Escherichia coli to transform the microorganism, and the transformed microorganism is proliferated in the presence of a carbon source. The product is isolated from the proliferated microorganisms and purified to provide the objective poly-3-hydroxyalkanoic acid useful as alternative plastics.  By this method, highly pure poly-3-hydroxyalkanoic acid is readily and cheaply produced in large scale.

Title: Deadlock avoiding system upon execution of program
Inventor: TAKEUCHI ATSUO
IPC: G06F9/52
Filed: 1990-10-05
Abstract: PURPOSE:To prevent the reoccurrence of a deadlock so as to prevent the deterioration in the processing performance by delaying the reexecution of each program against the occurrence of the deadlock. CONSTITUTION:A deadlock avoiding mechanism 2 measures the average processing time of one transaction by a program with a built-in timer and manages the measured data. When a deadlock occurs, the mechanism 2 reads out the average processing time of the deadlocked program and issues a transaction reexecuting instruction after confirming that the average processing time has elapsed with the built-in timer. In other words, when a deadlock occurs while program is executed, the reexecuting instruction is delayed by the average processing time of the transaction of the deadlocked program. Therefore, reoccurrence of the deadlock and, accordingly, the deterioration in the processing performance can be prevented.

Title: Power source unit
Inventor: MOCHIDA NORIHITO
IPC: G06F15/78
Filed: 1990-10-05
Abstract: PURPOSE:To easily and inexpensively obtain such a constitution that does not allow VIO to exceed VDD by using a DC voltage source and two or a plurality of pieces of rectifiers connected in common on the anode side and connecting the cathode of one of the rectifiers to the power supply terminal of a microcomputer and that of the other rectifier to a power supply terminal for load. CONSTITUTION:A voltage VOUT which nearly depends on the Zener voltage of a Zener diode 2 is outputted across the GND terminal 7 and output terminal 6 of a DC voltage source 1. When the electric current I1 flowing to a microcomputer 10 and the other current I2 flowing to a load circuit are equal to or larger than I', the difference between the forward voltage VF1 of a rectifier 9 and the forward voltage VF2 of another rectifier 11 always becomes  VF. Therefore, a voltage which is lower than the output of the DC voltage source 1 by the forward voltage of the rectifier 9 becomes the power source VDD to the microcomputer 10 and another voltage which is lower than the output of the voltage source 1 by the forward voltage VF2 of the rectifier 11 becomes the power source VL for load.

Abstract: PURPOSE:To obtain a distance detector for vehicle which can deal with a bright part and a dark part at a definite judgment standard with reference to a change in illuminance outside a vehicle and which enhances the accuracy of a distance detection. CONSTITUTION:A sensitivity correction table which is used to correct the sensitivity of an image which has been image-sensed by CDD cameras 11a, 11b is written in individual LUTs 33a, 33b for a data correction part 32. Then, by using the sensitivity correction table, brightness data on the image-sensed image is logarithmically converted in a region in which a noise component proportional to brightness is dominant and whose brightness is a prescribed value or higher. On the other hand, in a dark region whose brightness is at the prescribed value or lower, the data is proportionally converted in order to avoid increasing the noise component not proportional to the brightness. Thereby, when the coincidence degree of a right image with a left image is evaluated, the apparatus can deal with a bright part and a dark part at a definite judgment standard value, and it is possible to avoid a complicated operation to change a plurality of judgment standard values every time.

Abstract: PURPOSE:To facilitate the arrangement of telegrams on a reception side by storing the page sequence of the telegrams according to destination terminals, and controlling the page sequence of the transmitted telegrams according to stored sequence information on the communication opposite terminals a time of transmitting the telegrams. CONSTITUTION:Facsimile accumulating/multiple-address communication equipment M stores control information, which decides whether the page sequence of the telegram read and transmitted from a telegram storage part 4 is set at an ascending sequence or descending sequence, according to the communication destination terminals, and when the telegram accumulated in the telegram storage part 4 is transmitted to the communication opposite terminal stored beforehand, the page sequence of the transmission telegram is controlled in the ascending sequence or in the descending sequence according to the stored control information on the communication opposite terminal. Thus, since the page sequence of the telegram read and transmitted from the telegram storage means 4 can be set so that the page sequence of the telegram stored on the receiving side may be always constant, the arrangement of the telegram on the reception side can be simplified, and mistakes such as the erroneous recognition of a telegram pause, or the mixture of telegram pages can be reduced.
