Title: Compound semiconductor multilayer thin film and magnetic sensor
Inventor: TANAKA TAKESHI
IPC: H01L43/10
Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To make it possible to make compatible an increase in the mobility of InSb layers in a compound semiconductor multilayer thin film, which is used for a magnetic sensor or the like, with an increase in the resistance of the InSb layers. SOLUTION: A compound semiconductor multilayer thin film is formed into a structure, wherein an InSb buffer layer 2 doped with one of Al, Be, Zn, Mg, O and Ga as impurities and an undoped, Te-doped or Se-doped InSb active layer 3 are deposited in order on a semiinsulative GaAs substrate 1. By doping the one of the Al, the Be, the Zn, the Mg, the O and the Ga to the part of the layer 2 having bad crystal characteristics, the resistivity of the layer 2 is augmented and most of a current is contrived so as to flow in the side of the layer 3 having comparatively no crystal defect, which is attributed to the main cause of the reduction in the mobility of the layer 2. As a result, the InSb layers result in showing excellent electrical characteristics of a high mobility and a high resistance as a whole.

Title: Optical scanner for electrophotographic printer
Inventor: HIROSE YOJI
IPC: G02B26/10
Filed: 1995-01-13
Abstract: PURPOSE: To obtain a mechanism for quickly adjusting the intervals of two or more laser beams at a low cost, in an optical scanner for writing a latent image on a photoreceptor with two or more laser beams by providing an optical path position deciding member in a position in the vicinity of the photoreceptor which is at a distance equal to the distance between a rotary reflection mirror and the photoreceptor, for adjusting the intervals of the beams on the photoreceptor. CONSTITUTION: The optical path position deciding member 12 is arranged in the vicinity of the photoreceptor 11, so as to make the distance between the rotary reflection mirror 9 and the optical path deciding member 12 equal to the distance between the rotary reflection mirror 9 and the photoreceptor 11. Then, a beam interval adjusting member 6 is rotated to obtain a prescribed beam interval, while output from the member 12 is made visible by an optical path position confirming member 13. Since the interval of two laser beams can be adjusted, it is unnecessary that printing is executed by the adjustment of the intervals of plural laser beams. Thus, not only the adjustment is quicken but also a printing paper is dispensed with and further, the cost is drastically reduced as well.

When a preset r.p.m. is reached, power supply is interrupted to bring the wheel set A into free running state. Vibration at the bearing part 13a, 14a is detected by a sensor under that state and stored, in relation to the rotational speed of the reference mark, in a memory within an arithmetic circuit. Finally, the balance amount is determined at each angle based on the stored data and displayed 18.

Title: Production of non-directional silicon steel sheet having less aging deterioration and good surface property
Inventor: KOGA SHIGENOBU
IPC: C21D8/12
Filed: 1979-01-22
Abstract: PURPOSE:To enable steel sheet having less aging deterioration and good surface property to be stably produced without carrying out decarburization treatment by a method wherein carbon content is lowered to below a specified amount of carbon in the production of non-directional silicon steel sheet having high Si-content. CONSTITUTION:In the production of from high grade to intermediate grade non-directionality silicon steel sheet containing from 1.5-3.5% of Si, residual carbon content in the steel sheet is lowered to below 0.0030-0.0025% and Al content is made to >=0.15% or below 0.005% to avoid the formation of fine AlN which prevents crystal growth at the time of final annealing. When B is added to the steel, the amount of Al may be below 0.10% which is required for deoxidation, because AlN formation is controlled by B. B is added to the steel in such a proportion as to give a ratio of B/N of from 0.5-2.5. After the slab of the silicon steel having high Si-content and the above composition is hot-rolled, cold rolling is carried out once, or cold rolling including intermediate annealing without carrying out decarburization is carried out twice or more to produce steel sheet having final thickness. Then final annealing, which is not accompanied by decarburization, is carried out to produce non-directional silicon steel sheet having less aging deterioration and good surface property.

Title: Ultrasonic wave transmission
Inventor: SONODA SHINJI
IPC: H04R3/00
Filed: 1989-01-13
Abstract: PURPOSE:To enable formation of a transmission waveform with a high damping by applying a high voltage holdable for a fixed time length to a piezo-electric element with a certain time delay after a first high voltage is applied thereto with a time-series driving of a timing generator. CONSTITUTION:After an oscillation, a capacitor circuit C which performs a first oscillation is released electrically from a vibrator 1 with switches S1 and S2. A fixed DC voltage is applied direct to the vibrator 1 which is performing a mechanically free vibration to be held. With such an arrangement, as a displacement of the vibrator can be controlled at a desired timing and with a desired holding time, vibration can be suppressed on optimum conditions with respect to a vibration system. All of these can be controlled easily by a drive pulse of a timing generator 2. This enables the obtaining of a high-damping ultrasonic transmission wave form with limited ringing.

Abstract: PURPOSE:To constitute a loop network again quickly by sending a control signal to one of duplicated transmission lines for a predetermined time only from each slave station and repeating the transmission of the control signal till the control signal is received from the other side of the duplicated loop transmission line. CONSTITUTION:When a fault takes lace on a loop transmission line including slave stations RT1-5 and loop transmission lines N0-N5, a slave station close to the fault is in the state of loopback and disconnected from a loop network.

Thus, the loop network is built up again quickly without being restricted in the order of the connection of slave stations.
