Abstract: PURPOSE:To make the title motor small-sized and make it generate high torque by providing two or more small teeth in the internal peripheral surface of two or more pole teeth of a stator and bar-shaped magnets in a groove between small teeth displaced by 1/2 pitch of a rotor divided in the axial direction into two parts interposing a permanent magnet. CONSTITUTION:Two or more stator small teeth 3a are formed in the internal peripheral surface of two or more pole teeth 2 of an iron core 1 in the internal peripheral surface of a stator S, and a winding 4 is wound on the pole teeth 2. An iron core 6 of a rotor R, secured to a rotary shaft 10, is divided in the axial direction into two parts interposing therebetweeen a disk-shaped permanent magnet 9 magnetized in the axial direction, and the iron core 6 forms in its peripheral surface a rotor tooth 7b of dimension equal to the stator small teeth 3a, displaced by 1/2 pitch. Bar-shaped permanent magnets 8a, 8b are embedded in the rotor teeth 7b, and divided bar-shaped magnets 5a, 5b are embedded in the stator small teeth 3a. The bar-shaped magnet 5a, 5b, 8a, 8b are magnetized in the diametric direction with their thickness 0.3 times or more the thickness of the permanent magnet 9, negating its main magnetic flux. Thus, a product of high torque in small size is manufactured.

Title: Core for molding hollow body made of resin
Inventor: TSUDA OSAMU
IPC: B29C33/40
Filed: 1994-03-30
Abstract: PURPOSE:To rapidly and reliably carry out sealing of a connecting hole of a core by single action operation, by a method wherein a hole in a counterbore form is formed on the circumference of the connecting hole of the core left in a hollow body made of resin, a connecting device such as a connecting groove is formed in a side wall of that hole and a blind lid having a projection is prepared beforehand. CONSTITUTION:At the time of sealing operation of a connecting hole 21B of a core left behind in a hollow body 5 made of resin, a hole 21 in a counterbore form is formed in a connecting hole 21B part of the core. A connecting groove 21a is formed in a side wall. Hereby, since a blind lid 31 having a projection conforming with a connecting groove 21a is prepared beforehand, sealing can be performed rapidly and reliably by one touch operation. Since the blind lid 31 fitted with an O-ring 40 is used, a degree of airtightness of the blind lid 31 can be improved further. Since a connecting piece 31B conforms to the connecting groove 21a, the hollow body 5 made of the resin having a favorable pressure resistance can be obtained. Therefore, even if the hollow body has a complicated form, it can correspond sufficiently with the form.

Title: Synchronization adjustment method in time division duplex communication method and communication system using it
Inventor: SAKAI TAKASHI
IPC: H04L5/16
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To attain valid synchronization adjustment by preventing interference between slots with a simple communication equipment when one station and plural communication equipments conduct communication by a specific communication method according to a reference timing decided by the station. SOLUTION: After a terminal equipment 100 receives a signal of a transmission slot 102 at a delay time dt from a base station 0 and the terminal equipment 100 sends a signal through a transmission slot 106 to the base station 0 after the elapse of time 1/2Tf-Δt (Tf: frame period). The base station 0 receives the sent signal at a delay time of dt from the transmission of the terminal equipment 100. When the base station 0 receives the signal at a delay time t0 from a time tr without any delay, a relation of t0=2dt-Δt is established. In order to avoid interference, it is required to reduce the delay time than a guard time. Let an offset time 2dt be Δt, then the interference between slots is prevented as if no delay time were caused between the base station 0 and the terminal equipment 100.
