Title: Channel connection system
Inventor: OSAWA TOMOYOSHI
IPC: H04J3/00
Filed: 1986-01-10
Abstract: PURPOSE:To connect impartially each slave station whose propagation time differs by allowing a master station to select an optional station after a prescribed time and changing the designation of an operation enable line to another idle line when a connection request signal is sent to the operation enable line. CONSTITUTION:The master station sends a signal 1001 including connection designation channel information to each slave station from an equipment 10, and slave stations 1, 3 send respectively connection request signals 1002, 1003 to the designation channel. When the master station detects (20) a request signal arrived earlier, an inhibition device 30 sends a connection request inhibition instruction 1004 to each slave station (1, 3), a timer 40 supervises the signal propagation time to the salve station and when the signal 1003 arrives, the slave station 1 or 3 is selected (50) to assign the designation channel. Then the master station designates other connection channel to a slave station not assigned via an idle line change equipment 60 and a line designation equipment 10 to send a signal 1005. Thus, the slave station not assigned sends again a connection request signal 1006 or 1007 to the channel designated by the signal 1005.

Filed: 1981-01-14
Abstract: PURPOSE:To make a longitudinal ruled line continuous in a printer in which the quantity of charging in ink particles is controlled, by adding 1 bit per 1 column in the longitudinal indicating the ruled line. CONSTITUTION:A line image buffer 10 wherein dot image data is memorized and a ruled line information buffer 11 are provided. A ruled line information signal 17 is inputted to a charge quantity control ROM12 in addition to a charge quantity control information signal 16. When the signal 17 is inputted in the ROM12, 1 bit that indicates the ruled line is added to the image buffer 10 for every 1 longitudinal dot column. The height of said bit is controlled so that the height becomes the same size as a line feeding space (a). The bit is added to the space between tip of a ink jet nozzle 18 and a charge quantity control electrode 15 through a DA converter 13 and an amplifier 14. Thus the ruled line becomes continuous line. Even though the line feed space is changed, the same process can be performed.

Abstract: PURPOSE:To obtain the titled head having low magnetic resistance and high efficiency, wherein the magnetic characteristics of the upper and the lower magnetic film are almost the same, and with improved stability of the element characteristics and reliability by arranging a spacer having an almost trapezoidal section between the lower magnetic layer and substrate, and slowly tapering the lower magnetic pole layer. CONSTITUTION:A spacer layer 10 is formed on the substrate 1 coated with Al2O3, etc. SiO2 is used as the material of the spacer layer 10, the layer is formed in 2-4mu thickness over the whole surface of the substrate 1, and the unnecessary part other than the tip part 8 of the magnetic pole and a through-hole part 9 is etched. In this case, the cross section of the spacer layer 10 is strategically made almost trapezoidal and slowly tapered. The lower magnetic pole layer 2 is then formed thereon. Since the film thickness of the spacer layer 10 is controlled to the thickness about half the total thickness of the film coil 5 and the upper and the lower insulating layer 4 and 6, the cone angle of the top face of the insulating layer at the tip part 8 of the magnetic pole and the through-hole part 9 is reduced by half. Accordingly, the taper of the upper magnetic pole layer is eased, the wear on the inclined surface is reduced, and hence the magnetic resistance is decreased.

Title: Growing method for compound semiconductor
Inventor: KITAHARA KUNINORI
IPC: H01L21/205
Filed: 1990-01-11
Abstract: PURPOSE:To remove oxide on the surface of a substrate at relatively low temperature by heating the silicon substrate to a temperature higher than the crystal growing temperature of a compound semiconductor before the growing of the compound semiconductor, then decreasing the temperature lower than the growing temperature, exposing the semiconductor into the atmosphere of organic metal gas wherein elements contained in this semiconductor are components, and repeating these steps. CONSTITUTION:An Si substrate whose surface is cleaned is set on an MOCVD apparatus. Hydrogen is flowed, and the Si substrate is heated to 700 deg.C in this state. TMG(trimethyl gallium) is added to the hydrogen, and the substrate is left alone for five minute. The supply of the TMG is stopped, and the substrate is heated to 850 deg.C. Then, the temperature is decreased to 700 deg.C again. The TMG is mixed with the hydrogen, and the mixture is flowed. The supply of the TMG is stopped again, and the temperature is increased to 850 deg.C. The steps are repeated by several time. When a thin SiO2 film on the surface of the Si completely disappears, only the hydrogen is flowed. For example, in the growth of GaAs, the temperature is decreased to 450 deg.C. Polycrystalline or amorphous GaAs is grown on the entire surface. Thereafter the temperature is increased to 700 deg.C. The GaAs film is made to be the single crystal during the temperature increase. When 700 deg.C is reached, the single crystal of the GaAs is grown on the Si substrate.

Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To greatly improve adhesion and contact resistance of an electrode by preventing formation of a carbon layer by adopting an alloy of a metal which easily forms carbide and nickel as a material of an ohmic electrode. SOLUTION: An alloy of a metal which easily forms carbide such as metals of IVa, Va, VIa groups and nickel is adopted as a material of an ohmic electrode. For example, an Ni alloy layer 2 whose matrix is Ni is formed as an ohmic electrode on an SiC substrate 1, an Ni layer 3 is laminated on the Ni alloy layer 2 and titanium is adopted as a metal which easily forms carbide. If an alloy of a metal which easily forms carbide and Ni is used as an ohmic electrode, silicide is formed during formation of an ohmic electrode and remaining carbon atoms are consumed. Therefore, it is possible to avoid adverse effect such as an obstruction of soldering caused by formation of a carbon layer in a surface in a conventional method.

Abstract: PURPOSE:To irradiate always only a specific part of a rotary object to be irradiated, by arranging a light shielding mask having a window formed to the shape of an irradiated area between a light source and the object to be irradiated and rotating the light shielding mask synchronously with rotation of the object to be irradiated. CONSTITUTION:A light shielding mask 4 having a transmission window 3 which shields areas other than an irradiated area 1 from light is arranged between a light source 2 and an object 5 to be irradiated and is rotated synchronously with rotation of the object 5 to be irradiated. When the area having the shape 1 at the time, when the object 5 to be irradiated is vertical to an optical axis (z), is reduced to have a shape 6 by rotation of the object 5 to be irradiated on the (y) axis at an angle theta to the (z) axis, the area of the window 3 is reduced to a window 7 and is varied at the same rate as the irradiated area, and therefore, the range of the irradiated area 1 is always irradiated accurately at the optional rotation angle theta. Thus, one mask is used to irradiate continuously only an optional area of the rotary object to be irradiated.
