Filed: 1989-04-24
Abstract: PURPOSE:To automate the confirmation and inspection of the soundness of the flange part of the pressure vessel and to enable underwater inspection by mounting a system rack on the flange and fixing it to a stud bolt. CONSTITUTION:The system rack 11 is mounted on the flange surface and fixed to the stud bolt by a fixing mechanism 14, and the flange surface is inspected by a probe which travels along one travel guide 22 of the system rack 11. Further, a probe 49 which swivels around the fitting hole of the stud bolt is provided on a travel vehicle 34 which travels along the other travel guide 32 to perform flaw detection at the periphery of the bolt fitting hole. Further, flaw detection in the stud bolt center hole is carried out by a probe 63 which is mounted on the travel vehicle 34, inserted into and extracted from the center hole of the stud bolt, and rotatable. Consequently, the flaw detection inspection of the three places required to confirm the soundness of the flange part 2 is carried out automatically by one device even underwater without being carried out in a dry state.

Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To perform excellent auditory weighting for a broad-band signal like music. SOLUTION: For an input signal, linear prediction of p'th order (41) is performed to constitute a reverse filter 42, the prediction residue of the input signal is found through the reverse filter 42, and its residue signal is processed by linear predictive analysis (43) of (n)th order (n>p) to generate a linear filter (45), whose impulse response is calculated (47), converted into a frequency range (49), and deformed (51) with auditory characteristics.  A linear predictive filter 44 of (p)th order, on the other hand, is generated, the frequency range signal of its filter coefficient is deformed (50) into auditory characteristics, the error signal between the input signal and composite signal is converted (53) into a frequency range, and the error signal is multiplied by the outputs of converting means 50 and 51 to give auditory weight (52 and 54); and encoding is carried out so that the error becomes minimum.

Title: Thermal treatment device
Inventor: TOCHIKUBO HIROO
IPC: H01L21/22
Filed: 1989-04-26
Abstract: PURPOSE:To prevent dislocation due to thermal stress from taking place in a wafer by establishing a connection between wafer retention grooves and the wafer so that stress at each point of contact with the opening edges in the wafer retention grooves becomes less than yield stress in the case of thermal treatment. CONSTITUTION:A wafer 1 is supported in a state that a part of the outer peripheral part of the water is inserted into retention grooves 12 and is placed against retention members. In such a case, as the groove width (d) of each retention groove 12 allows same surplus S for fitting the wafer into each groove, the wafer 1 has an inclination at the inside of the retention groove 12 and leans against a rising wall. Then, when the allowance S is less than 100mum, the groove width (d) is established so that a distance L between the uppermost point of contact 14 and the lowermost point of contact 15 with which the wafer 1 is in contact respectively in the retention grooves may become more than 15mm and less than the diameter of the wafer 1. In other words, each groove width (d) is established so that the wafer 1 supported at the retention grooves 12 allows each stress acting upon respective points of contact to be less than yield stress at the temp. of 1200 deg.. In this way, the state of stress prevents dislocation due to thermal stress from taking place in the wafer.

Title: Automatic ticket examination machine
Inventor: TSUCHIYA SHINJI
IPC: G07B15/00
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To precisely record data in a ticket when a magnetic ticket and a noncontact type ticket are used by inhibiting entrance/exit if the noncontact ticket is not in the communication range of a communication area when the entrance/exit can be executed with the result of an arithmetic processing based on the data recorded in the magnetic ticket and the noncontact ticket.

When the arithmetic processing of entrance/exist is executed and the entering/exitting are permitted, the entrance/exit are permitted only by the noncontact ticket (S104). When the main body waits for the supply of a magnetic ticket, and the magnet ticket is supplied, the data of the magnetic ticket is read (S106 and 108). When the noncontact ticket goes outside of a communication range of the antenna before the arithmetic processing of the supplied magnetic ticket is terminated (S110), the entering/exitting are inhibited, and a guide for 'Place the noncontact ticket on the antenna' is shown via a display screen and a speaker (S112).

At this time, a point of maximum gammais allowed to correspond to a zero crossing point of delta shifted from this point by a time gamma2/2. Thus, the zero crossing point of the secondary differential signal corresponds to the level inversion point of the recorded signal.
