Title: Water thrust reducing method at transition time of pump water wheel
Inventor: IIJIMA HARUO
IPC: F03B11/06
Filed: 1981-05-15
Abstract: PURPOSE:To reduce the water thrust of a pump water wheel during a transition  period, by arranging an auxiliary balance tube between a runner back pressure  chamber and a draft pipe additionally and parallelly to a balance tube arranged  for reducing the water thrust at the time when a transient phenomenon such as  interception of the load of the pump water wheel or the like occurs. CONSTITUTION:A back pressure chamber 1 is connected to a lateral pressure chamber 3 through a balance tube 4, and a back pressure chamber 2 is connected to a draft pipe 9 through a balance tube 6 and further through a balance  tube 5 in parallel on which a normally closed automatic valve 10 is interposed.  When a transient phenomonon occurs, as the automatic valve 10 is opened and  the runner back pressure chamber 2 and the draft pipe 9 are connected through  by the balance tubes 6, 5, a downward water thrust during the transition period  can be restrained to the normal water thrust or below.

Title: Optical multiplexer-demultiplexer
Inventor: TERAHARA TAKAFUMI
IPC: H04B10/29
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To provide an optical multiplexer-demultiplexer that keeps balance of each wavelength optical power of a wavelength multiplex signal light, before and after input and output. SOLUTION: This optical multiplexer demultiplexer 1 has a building block, provided with an optical ADD-DROP multiplexer OADM circuit 10 that branches/inserts a signal light of a specific wavelength with respect to a wavelength multiplex signal light sent through an optical fiber of a trunk line system, an ADD light power control section 20 that controls the power of an ADD light inserted by the OADM circuit 10, based on the power of a DROP light branched by the OADM circuit 10. The ADD light power control section 20 measures the power of the DROP light and the ADD light and controls the ratio of the power of the DROP light to make the power of the ADD light constant. Thus, the power of a signal light with each wavelength before and after input/output of the optical multiplexer-demultiplexer 1 is kept constant.

Title: Shell for balloon and its manufacture
Inventor: TOREISHII REI BAANZU
IPC: B64B1/40
Filed: 1982-04-28
Abstract: A balloon envelope is disclosed which has the ability to minimize and isolate destructive tears, and which comprises a latticework of interconnected vertical and lateral reinforcing tapes which form open areas therebetween, and with a fabric panel overlying and covering each open area. The fabric panels are sewn to the surrounding tapes in a manner such that there is no direct interconnection between adjacent fabric panels. The envelope is fabricated by a procedure wherein the vertical gores, which are each composed of a vertical array of the fabric panels, are initially formed by sewing adjacent side edges of adjacent panels to intermediate laterally directed tapes, and then sewing a vertical tape component along each side of the resulting array of panels. The vertical side edges of the thus formed gores are then sewn together to form a sphere-like configuration.

IPC: B41J29/20
Filed: 1990-03-22
Abstract: PURPOSE:To prevent printing malfunction caused by heat generated from a print head, and to print characters, graphics, etc., in high quality by so controlling the head as to execute particular printing when counted value of counter means is a reference value or larger. CONSTITUTION:The number of dots to be printed upon printing of a print head 41 is sequentially added by counter means 31, and time counting means 29 subtracts a predetermined value from counter means 27 each time the means 29 measures predetermined time. When judging means 33 judges that the counted value of the means 27 is a reference value or larger, it so controls to print as to execute a particular printing by the head. In this case, the predetermined value to be subtracted from the means 27 is altered by subtracting value altering means 37 according to a detected temperature from temperature detecting means 51 for detecting a temperature. Thus, printing involving many number of dots to be printed in a state that the temperature of the head 41 is not substantially raised is performed by a normal printing operation, and processing capacity per unit time is not reduced.
