Title: Apparatus for obtaining three-phase position detection signal through single coil
Inventor: BAN ITSUKI
IPC: H02P25/098
Filed: 1994-10-25
Abstract: PURPOSE: To simplify a position detecting arrangement by arranging first to third sections, having different projection length and electric angles of predetermined width, on the outer circumference of a conductor rotor rotating synchronously and utilizing variation in the impedance of a coil disposed oppositely thereto. CONSTITUTION: A disc 15 is arranged with protrusions 15a, 15b, 16a, 16b, each having a width of 120 deg.. Each of recesses 18a, 18b also has a width of 120 deg.. A position detection element, i.e., a coil 10, is disposed oppositely to the protrusions through a small air gap. When the coil 10 faces the protrusions 15a, 15b, the impedance decreases due to iron loss. When the coil 10 passes the protrusion 16a, the facing area between the coil 10 and the salient pole 16a is decreased by half thus decreasing the reduction of impedance by half. Consequently, the impedance increases as compared with the case of a salient pole 15a. The impedance increases furthermore, when the coil 10 passes through the part 18a between protrusions.  In other words, the difference of impedance of the coil 10 is detected based on the variation in an AC high frequency conduction current value being applied to the coil 10 thus obtaining a position detection signal.

Title: Curtain wall
Inventor: MURAHASHI MASAO
IPC: E04B2/88
Filed: 1996-10-22
Abstract: PROBLEM TO BE SOLVED: To make the space between adjoining panels assuredly watertight by a simply structure. SOLUTION: This curtain wall, which has a tight member 69 arranged in the inside of a room in the extended part 63 of an upper panel 3, is provided with a space 67 between the end of the extended part 63 and an opposite surface 51 and a tip 72 of the tight member 69 abuts on the extended part 63 at above the lower end of the extended part 63. In this structure, the tight member 69 is never directly exposed to wind or rain and, because the space 67 is widedly secured by the tip 72 of the tight member 69 abutting on the extended part 63 at above the lower end, if water is collected in the space 67 it hardly enters the tight member 69 through the tip 72. Thus watertightness between the upper and the lower panels can be assuredly accomplished by a simply structure of only a single tight member 69.

Title: Demodulator for spread spectrum signal
Inventor: TAKEUCHI YOSHIO
IPC: H04W76/02
Filed: 1993-11-05
Abstract: PURPOSE:To nearly completely eliminate the interference between signals with less processings by obtaining the correlation with codes for the remaining error signals which is obtained by subtracting the sum of all copied signals from the accepted signal in the demodulator for spread spectrum signal. CONSTITUTION:Correlators 11-1K take values which are obtained by symbols for spread spectrum signals allocated individually for each spread spectrum signal included in input signals as the 0th correlation detected values. Then, a circuit 21 eliminating the mutual interference at the 1st stage takes the input signal and the 0th correlation detected value as input and outputs the primary remaining error signal, the primary correlation detected value and the sum of the 0th and the primary correlation detected values. Further, circuits for eliminating the mutual interference at plural stages operating like the circuit 21 are provided. Thus, the phase synchronization is performed for the sun of the Nth correlation detected value to be outputted from the last Nth staged circuit for eliminating the mutual interference. Respective signal demodulations are performed by discriminating bits. As a result, the interference can be completely eliminated with less processings.
