Patent JP-S616537-A (JP)
Title: Water heater
Inventor: TOMITA HIDEO
IPC: F24H1/40
Filed: 1984-06-19
Abstract: PURPOSE:To facilitate to prevent the local boiling from occurring by a constitution wherein the water fed in the title water heater ascends while being heated through a water pipe, in which a temperature detector is provided. CONSTITUTION:A feed water pipe 6 is inserted through a first header 1 into a water pipe 3a and has an open feed water port 8a formed by throttling its tip and an feed water port 8b open on its peripheral surface facing to the first header 1. The water pipe 3a and a water pipe 3b, in which a temperature detector 1 is provided, are connected with each other by means of a U-bend 12 in a second header 2. The water 11 fed from the feed water port 8a flows from the tip of the water pipe 3a through the U-bend 12 so as to rise in the water pipe 3b while being heated up to the temperature, which becomes higher as the water approaches the first header 1. As a result, the temperature distribution, in which the forced convection is dominant and which is thermally balanced, is formed in the water pipe 3b at all times. Because the amount of water in the water pipe 3b is small, the temperature change in the water pipe 3b during the ON-OFF operation of a burner 10 is large and severe, resulting in allowing for the temperature detector 9 to quicken the detection of the temperature. Consequently, the extinguishing lag of the burner 10 is reduced, resulting in eliminating the local boiling in the water pipe 3, which tends to occur just after the stopping of hot water supply.

Title: Screening device for integrated circuit
Inventor: EGUCHI YASUO
IPC: H01L21/479
Filed: 1980-09-11
Abstract: PURPOSE:To discover trouble early, and to protect a normal sample by a method wherein patterning action is monitored by sensing patterning signals activating an integrated circuit substrate on the integrated circuit substrate, and an overcurrent interrupting element is formed onto the integrated circuit substrate. CONSTITUTION:The activating signals sense-backed through the integrated circuit substrate and a predetermined voltage level are compared in a block 9, and sampling is checked whether or not the activating signals agree with an activation pattern at the time of drive. When the signals disagree, the signals are latched by means of a block 10, and forwarded to a control section 1 as the abnormality of a signal system. Even when either of a format control section 4, a pattern driver section 5, a connector section 6 and the integrated circuit substrate section 7 get trouble, thouble is detected in the blocks 9, 10 because right signals are not transmitted. Bias voltage is sense-backed through the overcurrent interrupting element such as a fuse in the integrated circuit substrate, and currents are interrupted when overcurrents flow-in due to fracture, etc.

The light of the wavelength lambda1 of the light reflected by the face 4 is transmitted through said film and the light of the other wavelength is reflected therefrom. The reflected light is made incident on the 2nd total reflection face 5. The light of the wavelength lambda2 is transmitted therethrough. The light of the wavelengths lambda1, lambda2 is thus demultiplexed by the same film 2.

IPC: H04N5/341
Filed: 1990-05-18
Abstract: PURPOSE:To improve the generality of a shift register by providing the shift register with the 1st and 2nd switching circuits and selectively actuating respective circuits. CONSTITUTION:When a switching control signal CH is set up to an 'H' level, switching elements Ya, Xa in a switching control circuit are turned on and switching elements Yb, Xb are turned off, so that inputted data DS are transferred in a direction (positive rotation direction) from a front stage side transfer element to a rear stage side element. When the signal CH is set up to an 'L' level, the switching element Ya, Xa are turned off and the elements Yb, Xb are turned on, so that the inputted data DS are transferred to the reverse direction from the front stage side transfer element to the rear stage side transfer element. Since the switching control circuit is integrally arranged, reversible transfer can be attained, and since the transfer direction can be properly changed during the operation, the application range of the shift register can be expanded.
