Patent JP-H04158283-A (JP)
Title: Magnetic flux density detector
Inventor: ISHIKURA TAKURO
IPC: G01R33/06
Filed: 1990-10-22
Abstract: PURPOSE:To hold an operation point approximately constant regardless of temperature change by connecting both the input terminals of a Hall element to a power source line and coupling both the output terminals thereof to a comparator to generate the potential difference between both the output terminals with the use of a resistance. CONSTITUTION:In a Hall element HD, four resistances R3-R6 of same resistance value are made bridge composition and two opposed points of a bridge are derived into both the input terminals 11, 12 through two resistances R7, R8 of the same resistance value to derive into both the output terminals R9, R10 of the same resistance value. And when the temperature is increased, the output of the Hall element HD itself lowers, so that, as it is, the output Hall voltage of the Hall element HD does not reach specified potential difference if higher magnetic flux density than expected set point generates. In order to block such a state, a material of a larger temperature coefficient than that of the Hall element HD is used as an action point adjustment resistance R11. Thereby, together with the increase of the resistance value of the resistance R11 due to the temperature increase, the potential difference generated in the resistances R9, R6 decreases to control the fluctuation of an operation point regardless of the temperature change.

Abstract: PURPOSE:To obviate a troublesome work of cut-removing chips after tapping work by performing one time or repeating several times reverse and normal turn processes thereafter relatively retracting a main shaft, while it is reversely turned, to draw out a tap from a stop hole. CONSTITUTION:After cutting work of an internal thread in a stop hole, before a tap 50 is drawn out from the stop hole, this tap 50 is reversely turned by a fixed rotary angle, larger than its flute width angle further smaller than an angle with a tooth thickness angle added to the flute width angle, while normally turned by this rotary angle. Since the rotary angle at the time of this reverse turning is larger than the flute width angle, not separated chips 76, cut by a cutting edge 64 in a tap biting part, are brought into contact with at least a heel part of the preceding cutting edge 64 and folded in a reverse direction to the cutting time from the base end part. Thereafter by normally turning the tap 50 by the same turn angle, the chips are folded again in a direction equal to the cutting time.

Filed: 1989-11-02
Abstract: PURPOSE:To execute another processing by an excluded terminal by responding the impossibility of updating when there is a request to update a data file from the other terminal while the data file is updating according to a request from one terminal. CONSTITUTION:When one terminal, for example, a terminal 2N, out of terminals 2A-2N, outputs the updating request to a data file updating means 1 of a host computer system equipped with a data file 4, it is investigated whether a flag for control is set to a control file 3 or not. When the flag for control is set to the control file 3, the data file 4 is under updating and such a state is responded to the terminal 2N giving the request. Thus, since the updating condition of the data file is discriminated in the terminal 2N, the effective control of the terminal 2N itself such as the execution of the other processing, etc., is enabled.

IPC: H01J61/073
Filed: 1986-12-03
Abstract: PURPOSE:To reduce the drop of the anode without making any impropriety to the other parts, by sealing both openings of a luminous bulb with bolckages which hold the main electrode and the auxiliary electrode respectively, and forming the auxiliary electrode with a material of a larger work function than that of the main electrode. CONSTITUTION:In an AC lighting, the pontentials of the main electrode 4A and the auxiliary electrode 5A held by the same conductive ceramic blockage 2A are made equal. As a result, in a half cycle when the main electrode 4A acts as an anode, the electrons flow to both the main electrode 4A and the auxiliary electrode 5A, as if the main electrode 4A is expanded, and the drop of the anode can be reduced. On the other hand, in a half cycle when the main electrode 4A acts as a cathode, the emission of electrons is only from the main electrode 4A, but not from the auxiliary 5A, since the auxiliary electrode 5A is composed of a material with a larger work function. Therefore, the capacity as the cathode is small, and the temperature rises easily. Consequently, the increase of the drop of the anode can be avoided without reducing the electron radiation.
