Abstract: PROBLEM TO BE SOLVED: To provide an image recording device capable of obtaining a stable image in every environment without being affected by the temperature and humidity of the environment. SOLUTION: In an image recording device in which a electrostatic latent image is formed by electrically charging and exposing a photoreceptor 41, and the development is carried out by sticking a toner image on this electrostatic latent image in the development process; the potential damping factor of the photoreceptor 41 due to exposure is made to have a positive characteristic to temperature and humidity, and also the initial charge potential of a charging device 42 is made to have a positive characteristic to temperature and humidity, and the photodischarge characteristic curve of the photoreceptor 41 at the time when temperature and humidity environments have changed is made to have a crossing region,  so that the variations of the initial charge potential and the photoreceptor photodischarge characteristic due to the variations of temperature and humidity can be offset by the combination of these characteristics and further, the variation of latent image potential to the environmental variation can be restrained by carrying out the binary image exposure by the exposure value in the crossing region being the offset point.

Title: Generator field rectifier circuit
Inventor: KOMURO TOMOKO
IPC: H02H3/08
Filed: 1996-08-12
Abstract: PROBLEM TO BE SOLVED: To prevent short-circuiting between rectifier units by giving an alarm to the operator of a generator when a closedcircuit failure occurs in one rectifier element of the rectifier units by installing one rectifier element failure detector provided with a detector, comparator, and an alarm to each rectifier element. SOLUTION: When a closed-circuit failure occurs in a rectifier element 6a, a detector 14b finds the average value of the voltage across both terminals of the element 6b, because the voltage increases when the element 6b is turned off. Then a comparator 16b compares the average value with a set voltage value set by means of a setter 15 and an alarm 12 gives an alarm through an alarm device 17b based on the compared result. Since the operator of a generator can immediately recognize the abnormality when the closed-circuit failure occurs in one rectifier element in a rectifier unit 5, the operator can start preparation for maintenance work before it becomes necessary to disconnect the faulty unit. In addition, the period until the maintenance work and the output of a generator can be maintained equally to those before the alarm is given.

Abstract: PURPOSE:To erase an unnecessary part of a signal recorded on a magnetic tape and a fine unnecessary part between a recording and reproducing head and an erasing head together when a recording medium such as the magnetic tape runs. CONSTITUTION:When a counter 7 is cleared (reset), a command for the start of counting is transmitted through an OR circuit 9 to the counter 7, which starts counting a pulse signal generated by running the magnetic tape 3 in a prescribed direction shown by an arrow A.

Title: Electromagnetic flow meter
Inventor: OKAYAMA TSUTOMU
IPC: G01F1/58
Filed: 1991-08-26
Abstract: PURPOSE:To suppress time constant of eddy current by dividing a magnetic route at right angle to electrodes and in the direction of pipe axis. CONSTITUTION:Electrodes E1 and E2 are air tightly and insulatedly installed on a lining L as an insulator and a metallic non-magnetic pipe P to construct a measurement pipe P. A set of saddle type coils C installed on both sides of the measurement pipe P. A yoke Y is installed on the measurement pipe P from the outside of the coil C, and the inner side of the coil C is made to contact with the pipe P to form poles PP1 and PP2. A flux comes from the PP1, passes through the PP2, separated to right and left yokes, and returns back to the PP1. When current flow direction is reversed, the flux flow direction is reversed. An eddy current is produced primarily at a metal part opposed to the coil C, flows in the direction reverse to that of current through the coil, and the route of current is cut-off by divided yoke Y. Thus circular area/circular route of the eddy current f1owing through the yoke Y, i.e., inductance/resistance are lowered to reduce the time constant.

Title: Collision forecast apparatus
Inventor: KANNONJI MICHIHIRO
IPC: G01S13/931
Filed: 1984-10-11
Abstract: PURPOSE:To prevent malfunctioning due to deviation between the direction of advancing a vehicle and that of outputting a sensor beam, by comparing with the second reference distance predetermined the distance detected in a specified time after the detection of the first reference distance predetermined is dicriminated. CONSTITUTION:First and second discrimination means derive a discrimination output when an obstacle reaches first and second reference distances l1 and l2 on a sensor beam 2. A passage detecting means sets, for example, eight obstacle detection points lA, lB...lH between reference distances l1 and l2 and derives an output when an obstacle passes by each of the detection points. In response to the output of a second discrimination means, a relative speed between a vehicle 1 and the obstacle is detected when the obstacle reaches the reference distance l2 and a collision forecast signal is issued when the relative speed exceeds a specified value while an output of the passage detection means exists. Therefore, the passage of the obstacle by all of the obstacle detection points lA-lH is detected though opponent vehicles 3 and 4 cross the reference distances l1 and l2 accidentally, a forecast signal output means will derive no output, which eliminates malfunctioning.

Title: Control unit for resonance type electromagnetic vibrator
Inventor: NONAKA TAKEYOSHI
IPC: B65G27/32
Filed: 1981-12-28
Abstract: PURPOSE:To aim at a reduction in power consumption, by controlling frequency of the exciting force of a subject body so as to be adjusted to the characteristic frequency of a resonance type electromagnetic vibrator, while also controlling the magnitude of the exciting force so as to cause amplitude of the said subject body to adjusted to the desired one. CONSTITUTION:In a stationary state, a trough 2 is vibrating in the desired amplitude with frequency commensurate to the resonance frequency but when load is imposed on the trough 2, amplitude of the trough 2 tries to become smaller whereby the resonance frequency in a vibrating system inclusive of the load falls off. At this time, the amplitude of the trough 2 is detected by an amplitude detector 8 and compared with the set amplitude valve by a comparator 14, through which an AC DC converter 5 produces a DC output in order to meet this setting value at all times, so that even in a loaded state, the trough 2 vibrates at the desired amplitude. Simultaneously, phase difference between the exciting force and the amplitude is detected and compared with the set phase difference by a comparator 10 whereby frequency of the AC output produced by a DC AC converter 7 is controlled and thereby the state of resonance is maintained.
