Title: Vehicle's driving azimuth detecting apparatus correcting disturbed geomagnetic azimuth
Inventor: NAKAYAMA OKIHIKO
IPC: G01C17/28
Filed: 1989-02-28
Abstract: When a vehicle is driven in a disturbed geomagnetic area, a geomagnetic azimuth sensor signal does not correctly reflect the actual driving azimuth of the vehicle. Moreover, a gyroscopic azimuth sensor signal drifts with time. A variation amount of the acquired geomagnetic sensor signals at units of distance is subtracted from variation amount of the acquired gyroscopic sensor signals at units of distance and the result is used to determine the quality of the geomagnetic conditions. The driving azimuth is processed on the basis of the conditions determined. so as to obtain a driving azimuth similar to the actual driving azimuth.

IPC: H01L21/36
Filed: 1992-08-20
Abstract: In a method for producing a II-VI compound semiconductor device including mercury, a thin film 9 comprising a group II element or a group II compound, which is solid at a room temperature, is deposited on a surface of a p type II-VI compound semiconductor 5, and annealing is carried out to diffuse the group II element from the thin film into the p type II-VI compound semiconductor, whereby a region of the p type II-VI compound semiconductor, on which the thin film is present, is converted to n type, resulting in a p-n junction 6. Therefore, instruments and material are easily handled, increasing work efficiency and productivity. In addition, the annealing is carried out without a complicated temperature profile, resulting in a simple process. <IMAGE>

Title: Consumable electrode dc arc welder
Inventor: MORIGUCHI HARUO
IPC: G05F1/08
Filed: 1992-09-08
Abstract: A consumable electrode DC arc welder rectifies 2 an AC input 1, converts it to a high frequency AC using an inverter 4, and rectifies it again 7 to provide a DC supply to the load 11. The output voltage Va is stabilised by comparing it 18 to a reference voltage Sr and using the output to control the inverter. The output current Ia is measured and differentiated over time 32 to discriminate between shorting and arcing. In the event of shorting, or if low output voltage is detected 22 the reference voltage in the feedback loop is reduced 29. This prevents spattering. <IMAGE>
