Title: Digital/analog converting device
Inventor: KUBO MITSUMASA
IPC: H03M1/04
Filed: 1986-09-09
Abstract: PURPOSE:To automatically make an adjustment with high accuracy by adjusting the level of a digital dither and reducing an error in subtraction. CONSTITUTION:Digital multiplication between a coefficient K and a dither Y is performed by a multiplier 7 in a stop state where a digital information signal X is zero. The coefficient K outputted by a coefficient multiplier 9 is small after resetting, so a subtracter 5 outputs a dither with a high level and a sample holding circuit 17 operates in synchronism with the clock of a clock signal generator 8 to store the output of a rectifying and smoothing circuit 16. A comparator 18 compares the output of the circuit 16 which is one sampling period before with the current output and increases the coefficient K obtained from the coefficient multiplier 9 in response to the clock signal. when both inputs of the subtracter 5 coincide with each other substantially, the coefficient multiplier 9 stops up operation and latches the current coefficient.

Abstract: PURPOSE:To prevent a safety valve of pressure from freezing, by a method wherein a safety valve of pressure and a low temperature actuation valve are combined and a circumferential temperature of the safety valve of pressure is made to maintain at a value more than the freezing point by making use of hot water in a water heater at the time of a low temperature. CONSTITUTION:When pressure at a supply opening 2 side to be connected with a hot water supply side of a water heater becomes high, a safety valve of pressure 5 is moved against a bounce of a spring 19, a valve seat 4 is released and hot water is discharged to an outlet 3. When an atmospheric temperature becomes lower than a set temperature of a wax thermoelement 8, wax in the element 8 loses pressure, the element 8 is ascended by making an elastic part 81 contract by a bounce of a spring 18, a movable guide 14 is ascended also, a low temperature actuation valve 7 is made to ascend by hooking the tip of the valve 7 by the bottom of the movable guide 14, a valve port 61 is released, hot water is discharged to an outlet 3 through a liquid hole 92 of a casing 9 and a temperature in the vicinity of the safety valve of pressure 5 is maintained at a value more than a freezing point. When the pressure is regained by increasing a temperature of the element 8, the low temperature actuation valve 7 is descended and the valve port 61 is closed.

Title: Packaging structure
Inventor: AMITA JIYUNICHI
IPC: B65D5/462
Filed: 1995-08-22
Abstract: PROBLEM TO BE SOLVED: To prevent breakage at the time of removing an inner case from an outer case to improve removal operation by providing a plurality of holes which are opened by applying pressure to a tab from opposite ridges on a top plate of the inner case. SOLUTION: When a product is necessary, a lid of an outer case C is opened. Then a part of U-shaped perforations is pressed to push down a hole forming piece 3b to open a hole. Since a part below the hole forming piece 3b is hollow, the pushed piece 3b may not come into a head of the product at the time of opening the hole, so that the product may not be damaged. By lifting this part with a finger inserted in it, an inner case B is taken out of the outer case C. At the time of taking out the inner case B, since a fold line of the hole forming piece 3b is located on a ridge of a top plate, a point of application of force functioning to the top plate of the inner case B is close to a side of the inner case, so that force functioning to the top plate is largely dispersed to a perpendicular side. Thus the top plate is not likely to flex nor be broken.
