Patent JP-H1183383-A (JP)
Title: Heat exchanger
Inventor: WATANABE AKIMICHI
IPC: F25B39/00
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To enhance the heat exchange performance while preventing deformation of fin on the outermost layer by inflating a part of wall on the side plate side of the side tank of a heat exchanger toward the inside of a channel. SOLUTION: The wall of the inner side tank member 5 of a side tank 3 is inflated partially toward the inside of a channel to provide an inflated part 18. Since the inflated part 18 is bent oppositely to a side plate 13, strength of the wall is enhanced significantly against deformation in the direction inflating toward the side plate 13. The side plate 13, and thereby the fin 12 on the outermost layer, can thereby be protected surely against deformation. Since the inflated part 18 extends in the extending direction of the channel in the side tank 3, inflation can be prevented over the entire wall region of the inner side tank member 5. According to the structure, deformation of the side plate 13 and the fin 12 can be prevented surely and entirely.

Title: Pad supporting back plate of disc brake
Inventor: NAGAHARA SATOSHI
IPC: F16D65/092
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To effectively strengthen the rigidity of a back plate itself and simultaneously secure the hooking margin to a holding part for receiving the reaction force of braking action by forming a back plate for supporting a pad into a recessed substantially spherical surface or a substantially truncated quadrangular pyramid. SOLUTION: Each back metal 1 is set in such a manner that the respective locking parts 4, 5 are clamped between holding parts 7-10 formed on the caliper 6 side, and held in a designated position through the locking action between the locking part 4, 5 and the holding parts 7-10. The reaction force to the braking action applied to a pad 2 is caught through the locking action between the locking parts 4, 5 on the backward side seen from the rotating direction of the brake disc 11 and the holding parts 7-10. In this case, the back plate 1 is formed into a recessed substantially spherical surface, so that the hooking margin of the locking parts 4, 5 and the holding parts 7-10 on the caliper 6 side is increased to always obtain the sure locking state even if the pad 2 wears away.  Further, the rigidity of the back plate 1 itself can be remarkably strengthened by the reinforcing action of the recessed substantially spherical surface.

Title: Key encoder
Inventor: AKIYAMA TAKAO
IPC: G06F3/02
Filed: 1990-10-02
Abstract: PURPOSE:To invalidate multiple depression by making a key code outputted from a key encoder invalid when there is noncoincidence in the number of a signal input line in which a signal variation is recognized by a main encoder and a sub-encoder occurs. CONSTITUTION:By connecting each signal input line to each input terminal of a main encoder A-1 whose priority is the same in reverse to each other, the priority becomes reverse. For instance, in the case a signal variation occurs in two pieces of signal input lines (a), (b), the main encoder A-1 outputs a code LHL with regard to D2 whose priority is higher in input terminals D2, D1, and a subencoder A-2 outputs the LLH obtained by inverting an HHL with regard to D6 whose priority is higher in input terminals D6, D5, and noncoincidence is generated in the outputs of both the encoders. Subsequently, by inputting the outputs of the encoder A-1 and the encoder A-2 to a comparator A-6, a signal A=B' is generated, and at the time of noncoincidence, a signal of a high level H is outputted and a key operation becomes invalid. Also, on the matrix Y side, as well, it becomes invalid in the same way, therefore, all multiple depressions can be prevented.
