IPC: H02K5/04
Filed: 1989-02-15
Abstract: PURPOSE:To improve drainage effect by arranging a single annular rib for reinforcing a bracket and making one or a plurality of drainage holes through the projecting section of the annular rib formed on the underside bracket. CONSTITUTION:A drop 7 flows along a path in a motor shown by an arrow B and stored in an annular rib recess 2a at the inside of an underside bracket 2.

Accordingly, the cooling wind in radial direction is divided in two, and the cooling wind passing through the gap 16 between the iron press 14 and the end ring 8 cools the side of the end ring 8 of the rotor bar 7. Moreover, the pressure increase the action of the flow in radial direction is little, and the interference phenomena between the stator coil 3 and the end ring 8 is relaxed. Hereby, the rotor cooling property improves, and the duct noise can be reduced.

Title: Ac characteristic tester
Inventor: ITO HIDE
IPC: G01R31/28
Filed: 1995-02-23
Abstract: PURPOSE: To measure the transient time of a high speed signal without failure by integer-multiplying the pulse width of a synthetic signal, measuring and then dividing it by the integer. CONSTITUTION: The synthetic signal SUM output from synthesizing means 6 becomes an H level when first and second compared result signals CMP1 , CMP2 output from first and second comparing means 4, 5 have different logical levels. The transition time of a signal IN to be measured of a device 1 to be measured from an L level to an H level is accurately represented during this period. The pulse width of the signal SUM is narrowed if the frequency of the signal IN becomes high, and the measurement is failed. Therefore, the pulse width of the signal SUM is increased by n (integer) times by enlarging means 7, and measured by measuring means 8. The result is multiplied by 1/n, and actual transition time is obtained. Thus, the measurement can be performed even by a high speed signal without fail.

Title: Binding member of wire rod and binding method of wire rod
Inventor: KITAGUCHI KATSUMI
IPC: B21F99/00
Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To bring a heat contractive member into close contact with wire rods at a prescribed coiling interval to bind while holding the linearity of wire rods arranged in a spiral shape inner periphery by thermally contracting the heat contractive member having a prescribed heat contraction ratio in the direction of the spiral shape inner periphery. SOLUTION: The wire rod binding member 1a is formed into the spiral shape so that the band shape heat contractive member having the prescribed heat contraction ratio provides the prescribed inner periphery diameter D1. When heat required for generating heat contraction is applied to the heat contractive member, contraction is generated in e.g. the longitudinal direction of the spiral shape, and the inner periphery diameter D1 of the spiral shape is reduced as a whole. When heat is uniformly applied to the wire rod binding member 1a with a heater, heat contraction is generated in the direction of the inner periphery of the spiral shape, and the band shape surface of the heat contractive member is brought into close contact with wire rods 2 having the outer diameter D2 previously arranged in the inner periphery side of the wire rod binding member 1a to bind.  By this way, the uniform binding state is easily realized regardless of the number, the outer diameter, the material or the like of wire rods.

Title: Rotary head type reproducer
Inventor: TANAKA MASATO
IPC: G11B20/00
Filed: 1981-03-10
Abstract: PURPOSE:To achieve easy and low cost manufacturing of device, by scanning a head to (n) recording patterns recorded with a digital information signal added with an address signal by a number of times exceeding the number (n) and continuing the output. CONSTITUTION:An analog signal, e.g. audio signal to be recorded is applied to an input terminal 4 and an audio PCM signal is obtained. This PCM signal is applied to an encoder 6, where an error correction code and the like is added. At reproduction, the totational frequency of a rotary head 3 is selected higher than that at recording. Thus, since the number of scannings at reproduction is higher than that at recording, a reproducing scanning locus pitch is smaller than a track pitch and each of all the recorded tracks is traced with the reproduced scanning locus without fail without requiring tracking. Thus, since the tracking requiring head scanning with the recorded track one to one is unnecessary, no tracking servo with high accuracy is required, allowing to achieve easy and low cost manufacturing for the devices.
