Title: Information recording member
Inventor: ANDO KEIKICHI
IPC: G11B7/24
Filed: 1990-05-09
Abstract: PURPOSE:To prevent dimensional changes of the substrate surface due to recording laser beam and to prevent decrease in recording sensitivity by providing protective layers essentially comprising oxides, sulfides, carbides, serenides, nitrides, etc., in a multilayer structure adjacent to a recording thin film. CONSTITUTION:The first protective layer 3 is a thin film essentially comprising oxide, nitride, or carbide and has the thermal conductivity between >= 8 W/m.K and <= 60 W/m.K, and more preferably, >= 10 W/m.K and <= 50 W/m.K. The heat generated by irradiation of recording beam is diffused in the first protective layer 3 essentially comprising oxides, nitrides or carbides which have high thermal conductivity. The heat is then shielded by the second protective layer 2 essentially comprising oxides, serenides or sulfides having low thermal conductivity. Therefore, little heat reaches to the grooved resin 7, which prevents deformation or deterioration of the substrate.

IPC: F02G5/04
Filed: 1989-05-15
Abstract: PURPOSE:To drive a cogeneration system with high system efficiency even with different ratios of electric load and thermal load by providing a system which supplies steam generated by the use of exhaust heat of a driving source of a generator to a heat source unit. CONSTITUTION:Water which is boosted by a water pump 19 is evaporated by an exhaust gas heat exchanger 14, and flowed into a second three-way valve 20 whose opening is controlled by required electric power and thermal load. One part of steam which is flowed into the second three-way valve 20 is flowed into a steam turbine 18 and expanded. The work of this time is transmitted to a generator 23 for steam and electric power is obtained. On the other hand, the other part of the steam is introduced to a second pressure-reducing valve 21 whose opening is controlled similarly to the second three way valve 20. Cooling medium steam from the second pressure-reducing valve 21 is mixed with the steam from the steam turbine 18, and flowed into a double effect absorption refregerator 8 for condensation. The condensation heat is utilized as a heat source of the double effect absorption refregerator, while thermal effect for a cooler or the like is obtained from the double effect absorption refregerator 8 as an output.

Title: Picture display system
Inventor: TABATA TOSHIO
IPC: H04N5/46
Filed: 1989-05-15
Abstract: PURPOSE:To prevent baking caused when a picture pattern smaller than the screen is displayed by selecting a timing signal at random from plural timing signals with a different phase. CONSTITUTION:The number of scanning lines of a video signal by the high definition television system such as a MUSE base band signal is decreased by a scanning line number conversion means 4 and the resulting signal is stored in a time axis correction buffer memory 5. Then the generating timing of an address signal is controlled to vary the readout timing of the signal from the buffer memory 5 thereby moving the picture display position and avoiding the relation of position between the picture area and the space area from being fixed. The generating timing of the address signal is changed by generating plural timing signals with a different phase in advance, selecting one timing signal at random among them and using the selected timing signal to control the readout control means. Thus, baking caused by fixed picture and space areas is prevented.

Abstract: PURPOSE:To reduce the number of workers for calibration to one, by a method wherein a gas concn. indicator is provided with a means to maintain the max. value of the concn. of a gas, then, a worker blows a reference density of gas to a gas sensor at a remote point and returns to a main unit. CONSTITUTION:When a maintenance switch SWm is turned ON, a timer T1 is switched ON after a set time and a relay RY1 starts to work, which causes a contact RY1a to be switched over to a main amplifier MA through a peak holding circuit pH from a preamplifier PA to maintain the max. value of an output of a gas sensor S. A self-holding circuit SH is kept ready for alarming even when a line R is ON as a contact RY1b is turned OFF. With such an arrangement, a worker moves to apply a reference gas all the way to a gas sensor S located away from an alarm body and, then, returns to the main unit side of a gas detector to check an indication of an indicator unit 10. Afterward, the calibration of a gas concn. indicator M is performed.

Abstract: PROBLEM TO BE SOLVED: To surely prevent the clogging of a nozzle hole for a long period by attaching a metallic short pipe to the nozzle hole of a diffuser pipe and further sheathing the metallic short pipe with a flexible short pipe. SOLUTION: A metallic short pipe 3 with the inner diameter made identical to or slightly larger than that of a nozzle hole 2 is attached to the nozzle hole 2 of the diffuser pipe 1 of an aeration tank to prevent the formation of a dead angle. The metallic short pipe 3 is normally made of stainless steel and welded to the nozzle hole 2. The length is made 1 to 5 times, preferably 2.3 to 3.0 times, larger than the inner diameter. The metallic short pipe 3 is sheathed with a flexible short pipe 4 of rubber, etc., which is extended from the metallic short pipe 3. The inner diameter of the flexible short pipe 4 is so determined as to sheathe the metallic short pipe 3, and its length is made 1.5 to 3 times, preferably 1.7 to 2.3 times, larger than that of the metallic short pipe 3.  Under such conditions, the deposit is shaked down by the vibration of the flexible pipe 4 caused by the aeration, and the clogging of the nozzle hole 2 is prevented.
