Title: Manufacture of laminate heat exchanger with duct mounting frame
Inventor: MURAE SEN
IPC: F28D9/00
Filed: 1989-08-18
Abstract: PURPOSE:To reduce the number of assembly processes of a heat exchanger with a duct mounting frame and hence assure inexpensive mass production by assembling into a box shape a tube plate, a frame plate, and a sand member in the state where a core is internally mounted, and integrally simultaneously brazing and fixing them by bringing them into contact with each other a thier edges. CONSTITUTION:A pair of square side members 6 are brought into contact with the outside of a core 3, and the edge of a frame plate 5, and the edge of a tube plate 4 are brought into contact with each other perpendicularly to each other. The respective contact parts have flanges, one edges of which are folded at a right angle. A solder is put on the contact surfaces, and the core 3 is inner-packaged and the tube plate 4, the frame plate 5, and the side member 6 are assembled into a box shape. These members are placed in a high temperature furnace, and the contact surfaces are simultaneously brazed and fixed to each other in a united manner by melting the solder.

Title: Partially washing liquid detergent product
Inventor: IWAO SHUJI
IPC: C11D17/00
Filed: 1996-08-12
Abstract: PROBLEM TO BE SOLVED: To easily pour out a proper quantity of liquid detergent, and prevent a drip of liquid at in cleaning operation by forming an opening variable pouring-out hole in a pouring-out member to cover an opening of a vessel main body, projecting plural brush bristles to its periphery, and specifying viscosity of the liquid detergent. SOLUTION: At cleaning time, when a pouring-out member 30 is picked by hand and is pulled up from a vessel main body 10, the pouring-out member 30 rises while slidingly moving on a neck part until an annular projection 15 contacts with the lower end of an annular receiving groove 36. As a result, a clearance between a pouring-out hole 33 and a plug body 24 opens, and opening of the pouring-out hole 33 is fully opened, and opening of the pouring-out hole 33 continuously changes according to a moving degree in the middle of rising. The vessel main body 10 is inverted, and when a barrel part 14 is pressed by hand, a liquid detergent 3 is stored in a clearance between brush bristles 35. Next, a brush is cleaned by pushing the brush bristles 35 against a cleaning object.  At this time, the pouring-out member 30 is pushed to the vesse main body 10 side, and since the plug body 24 blocks up the pouring-out hole 33, a drip of liquid at cleaning work is prevented. A material whose viscosity at 25 deg.C is adjusted within a range of 0.01 P to 100 P is used as the liquid detergent 3.

Abstract: PURPOSE:To obtain a high quality demodulated chrominance signal with small sized hardware by detecting a chrominance signal to obtain time division multiplex signal cpmprising I, Q signals and using a low pass filter, an adder and a sub-sample circuit. CONSTITUTION:A digital chrominance signal subject to digital conversion by a sampling clock synchronously with the phase of I,Q axes is obtained and a 1st signal including the I and Q signals having a unified polarity whose polarity is inverted at each prescribed sample from the digital chrominance signal is obtained. Then the Q signal component is eliminated from the signal obtained by subtracting a 2nd signal from the 1st signal and only the I signal component is doubled for its level to obtain a 3rd signal. Then the signal being the addition of the 3rd and 2nd signals is sampled at a prescribed sample phase to obtain a separated demodulation output of the I, Q signals. Thus, the I, Q signals are processed by a signal format subject to time division multiplex to eliminate the need for independent system of the I and Q signal processing.
