Title: Lead extraction structure for piezoelectric body
Inventor: TABUCHI KEIZO
IPC: H04R17/00
Filed: 1989-01-12
Abstract: PURPOSE:To prevent the deterioration in the electric characteristic of a piezoelectric body by using a flexible conductive adhesives so as to connect a lead wire to an electrode of a piezoelectric body directly so as to eliminate the need for the use of solder for the connection of the lead wire thereby avoiding the effect onto the piezoelectric element. CONSTITUTION:The tip of a lead terminal 12 is overlapped to a position near a node point on an electrode 2 of a piezoelectric body 3 and a flexible conductive adhesives 11 is potted to the overlapped part. The flexible conductive adhesives 11 is potted in a way of covering a lead terminal 12 and the flexible conductive adhesives 11 is cured naturally or forcibly by hot air or the like and the lead wire 12 is directly connected to the electrode 2. Since no solder is employed for the connection between the lead terminal 12 and the electrode 2, no effect is imposed on the piezoelectric element 1 thereby avoiding the deterioration in the electric characteristic of the piezoelectric body 3 and the split of the resonance point. Moreover, no crack takes place to the piezoelectric element 1, the vibration of the piezoelectric body 3 is absorbed by the flexible conductive adhesives 11 to reduce the transmission of the vibration to the lead terminal 12 or the frame terminal 13 thereby preventing the breakage of the lead wire 12 due to the vibration.

Title: Calibration of demodulator
Inventor: KAREN KAFUEEDA
IPC: H04L27/18
Filed: 1989-01-12
Abstract: PURPOSE: To attain a highly accurate and a quick calibration by utilizing a statistic method for an analysis and a correction of received data. CONSTITUTION: Each available error factor is measured and received I and Q values are converted into solid line data. Namely the value of each vector determined by the pair (I, Q) is measured, and when the value of each vector is equal to '1', a demodulator is suitably functioned and calibrating adjustment is made unnecessary. When the value of each vector is not equal to '1', the proper number (n) of signals is measured. Then the parameter of a geometric model formed by measuring points is found out by the use of regression analysis. Thus statistic approach is used for the determination of the calibration coefficients of the demodulator. When the approach is executed, all coefficients are simultaneously found out, so that mutual influence is substaratially considered.

Title: Electric locking system
Inventor: NAKAMURA TERUHITO
IPC: E05B47/00
Filed: 1990-01-13
Abstract: PURPOSE:To automatically release discordance of ID codes by providing between an electric lock and an electric lock controller a repeater equipped with a non-volatile memory for storing ID codes, and locking or dislocking a door via the repeater. CONSTITUTION:An electric locking system comprises a repeater B interposed between an electric lock C and an electric lock controller A. The repeater B is formed by an I/F portion 2 for transmitting and receiving signals to and from the electric lock controller A, a light transmitting portion 2, a light receiv ing portion 4, an indicator 5, a controlling portion 1 comprising a CPU for signal processing, an oscillator 7 and a non-volatile memory a for storing ID codes. In changing ID codes, the system judges when an ID code does not accord with that stored in the memory 8 and there is no error that it is only the ID codes that do not accord with each other, and resends a signal requiring an ID code to be stored. Thereby transmission of a normal signal is possible even with mistakes in the setting of the codes.

Title: Production of optical disk
Inventor: GOTO YASUYUKI
IPC: G11B7/243
Filed: 1987-01-14
Abstract: PURPOSE:To eliminate a blind period by controlling the substrate heating conditions and the heat treatment time for a recording medium formed on a transparent substrate in the form of a film so that a crystallization state equal to an information erasion state is obtained. CONSTITUTION:When a film is formed on a transparent substrate, both the substrate heating temperature and the heat treatment time are controlled. For instance, a recording medium having a composition ratio of In40Sb60 is formed on a glass substrate with 100nm thickness by a dual vapor deposition process. In this case, the substrate temperature is controlled to 150-240 deg.C together with the treatment time controlled to the value between 30min and 4hr to obtain the conditions where the crystal grain size is equal to 20nm. As a result, the 20nm grain size is obtained with the substrate temperature set at about 200 deg.C and the heat treatment time set at about 2hr respectively. Under such conditions, the reflection factor of an initial state 1 shows about 30% and a recording state 2 and an erasion state 3 show the approximately constant levels of about 40% and about 30% respectively despite repetition of recording and erasing actions. Thus a blind period is eliminated.
