Patent JP-H01102270-A (JP)
Title: Plate for cooling
Inventor: NAKAGAWA AKIRA
IPC: F25D25/02
Filed: 1987-10-16
Abstract: PURPOSE: To prevent an external appearance and performance of a metal plate from being deteriorated owing to deflection and deformation of the metal plate upon refrigerator cooling operation by mounting the metal plate with the aid of a plurality of insertion holes and a stopper piece in a plastic frame peripheral part, and providing clearance absorbing thermal compression over the entire periphery. CONSTITUTION: A metal plate 5 is inserted into a space part 2c in a flange 2 of a peripheral part of a frame 1 through an insertion hole 7 from an oblique upper portion, and once the metal plate 5 is lifted, an engagement piece 2b is moved into an opening part 2a to bring the back of the metal plate 5 and a reception surface 4 of the plastic frame 1 into contact with each other. When the metal plate 5 is slided to the space part 2c on the opposite side of the flange 2, the metal plate is disengaged from the engagement piece 2b and the engagement piece 2b is returned to an original position with resilient force so that the metal plate 5 is kept in its predetermined clearance without being disengaged from the space part 2c.  Although the cooling plate 8 is exposed to considerable low temperature upon refrigerator operation, the metal plate 5 and the plastic frame 1 kept the predetermined clearance and a thermal compression difference between the metal and the plastic is absorbed, so that an external appearance and performance such as deformation and deflection are prevented from being lowered.

Title: Plane with cut width indicator
Inventor: TANABE HARUYUKI
IPC: B27C1/10
Filed: 1994-10-26
Abstract: PURPOSE: To enhance the efficiency of a cutting operation and improve operating ease by recognizing a cut width easily and positively. CONSTITUTION: A handle part 4H is moved in an arrow direction 90 by an operator who holds the handle. Then a wood is cut in the form of a strip within the limits of a cut width S2, and reference lines 8a, 8b are formed on a housing 4 along both end lines L1, L2 which are almost of the same width as both ends of the cut width S2. That is, if a hand electric plane is viewed from above by the operator, it is possible for him to recognize the cut width S2 easily and positively. Thus the efficiency of a cutting operation is enhanced and the operating ease be improved. As an alternative, the housing 4 can be painted in different colors instead of forming the reference lines 8a, 8b and the cut width S2 can be indicated by these colored boundary lines.  In addition, the cut width S2 can be indicated by positioning the boundary lines of covers 6a, 6b attached to the housing 4 almost on the same lines as both end lines L1, L2 of the cut width S2.

Title: Virtual connection setting control system for cell exchange system
Inventor: KATO MASAAKI
IPC: H04L47/80
Filed: 1996-10-03
Abstract: PROBLEM TO BE SOLVED: To realize the definition technology of a subscriber attribute in which the flexibility of a cell exchange system such as an asynchronous transfer mode(ATM) exchange system is sufficiently utilized. SOLUTION: A definite virtual path connection identifier(VPCI) is defined to each of two subscriber lines 102 (jA, #B) contained in an ATM exchange 101 as shown in figure (a). In this case, attribute data denoting a subscriber attribute have only been defined in the unit of the subscriber lines 102 (#A, #B) as shown in Figure (c) conventionally. On the other hand, in this system, the attribute data are defined to each virtual path in the unit of each VPCI as shown in Figure (b). Thus, for example, adoption of a different communication form for each different subscriber accommodation location number belonging the same subscriber is easily realized.

Filed: 1989-10-09
Abstract: PURPOSE:To suppress an interference to the receiving of broadcasting by providing electric wave absorbers which consist of a magnetic material surrounding a part of the connection wires between a frequency converting device and a heating coil. CONSTITUTION:Electric wave absorbers 24 to 26 which consist of magnetic substances are provided to surround at least a part of the connection wires between a frequency converting device 10 and a heating coil 22.

Title: Rotary actuator
Inventor: KONDO JIRO
IPC: H02K33/02
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To provide a rotary actuator which enables reduction in the weight of its rotor and hence reduction of the rotor core weight, without reducing the torque applied to a rotor. SOLUTION: A hollow part 36 into which a throttle shaft 12 is inserted is formed at the center part in the diameter direction of a rotor core 42. A hollow part 46 has an elliptical shape which has its long axis in the direction of the diameter of the rotor core 42. The long axis is extended along a line connecting a permanent magnet group 43, which is one of a pair of poles formed on the outer circumference of the rotor core 42 to a permanent magnet group 44, which is the other pair of poles. Since thin parts 42a are formed in the rotor core 42 at two center parts of the pair of poles of the rotor 41, and thick parts 42b are formed in the rotor core 42 at both the end parts of the pair of poles, the unevenness of flux density in the rotor core 42 is reduced, and a uniform flux distribution can be obtained. Therefore, the weight of the rotor core can be made relatively light, hence the weight of an actuator can be reduced without reducing the torque applied to the rotor.
