Abstract: The heat exchanger HE comprising a case 2 housing a plurality of heat transfer tubes 1 and a header 3 having a hollow main body 30 with an open edge 33. A side wall 21 of the case 2 is provided with a bulging portion 22 having a cylindrical circumferential wall 22a bulging out of the case 2 and an end wall 22b which blocks a tip portion of the circumferential wall 22a. Each end of the heat transfer tubes 1 is inserted into a penetrating hole 22c provided for the end wall 22b of the bulging portion 22, and is jointed to the end wall 22b, and the open edge 33 of the header 3 is fitted onto the circumferential wall 22a of the bulging portion 22, thereby forming a chamber 36 communicating with the inside of each heat transfer tube 1. Therefore, it is possible that the number of the members of the heat exchanger HE is reduced, the configuration is simplified, and the heat exchanger HE is easily manufactured at low cost.

Abstract: In the handle assembly, a combination lock (6) is opened by turning each dial discs (4) a given number of times to establish a combination of marks on the discs, and is incorporated in a handle (2) and disposed adjacent to a cylinder lock (13) in the handle. A receiver lever (16) pivoted on a base body (1), is controlled by a lock plate (5). A stopping plate (11), interlocked with a rotor (8) of the cylinder lock (13), engages receiver lever (16) pivoted to the base body (1), so that the handle (2) is held in its folded position. When the combination lock (6) is in its unlocked condition and the handle (2) is pulled, the receiver lever (16) is swung upward by the stopping plate (11) to release handle (2) from the base body (1). A plurality of slots (68) are formed on a bottom surface of a dent portion (100) of the handle (2).

Abstract: There is provided a handle assembly of thin type which permits through a computerized personal management system a plurality of persons to have easily access to instruments in a box with the handle assembly. Said handle assembly does not get out of order or break down owing to a collision or contact with other physical solid body.

Abstract: A substrates processing device having a tank in which process solution is contained, a bottle communicated with the tank through a conduit and located above an object to be processed with the process solution supplied, a nozzle located under the bottle, a support for supporting the object to be processed, and a changeover device for making pressure in it negative through a conduit when the process solution is to be added to it and also making pressure in it normal through the conduit when the process solution is to be supplied to the nozzle.
