Title: Etching method
Inventor: KAKIGI MASAMI
IPC: G02F1/136
Filed: 1998-08-05
Abstract: PROBLEM TO BE SOLVED: To provide an etching method in which etching residue is less liable to occur. SOLUTION: A resist 32 is formed on the top of a molybdenum layer 17. An etching soln. is diluted to 30-50% and the surface of the molybdenum layer 17 is washed with the etching soln. diluted to such a degree as not to etch the layer 17 for >=60 sec to remove an oxidized film 42 on the surface of the layer 17. The molybdenum layer 17 is then immersed in the etching soln. for conventional wet etching while keeping a metal of a different kind in contact with the layer 17. Aluminum which is baser than molybdenum is selectively etched by a battery effect. Since the surface of the molybdenum layer 17 is previously washed with the diluted etching soln., the molybdenum is uniformly etched and insular etching residue does not occur.

Title: Laminated integrated circuit element
Inventor: MIYAJIMA TOSHIAKI
IPC: H01L21/20
Filed: 1982-12-21
Abstract: PURPOSE:To enable to form a single crystal semiconductor layer of homogeneity and a large area and thus obtain a laminated integrated circuit element of good quality by using a dielectric of a high thermal conductivity for an insulation film interposed between a semiconductor layer. CONSTITUTION:An Mo film 13 is deposited on the surface of an Si substrate 11 and patterned to an electrode or wiring form. Next, a boron nitride film 15 is formed on the semiconductor layer after wiring to a film thickness of 0.5mm. or more. With the boron nitride film 15 as an insulation film, amorphous Si 21 is formed in the upper part to approx. 0.5mum, and thereafter the Si film 21 is single-crystallized by the irradiation of an Ar laser. Since the thermal conductivity of boron nitride is high, the heating by the laser beam is relatively rapidly transmitted to the periphery, and the uniformity of the temperature distribution of the amorphous Si can be contrived regardless of the presence of an Mo electrode, accordingly the single crystal of a uniform film quality and a large grain diameter can be prepared. In addition to boron nitride, a dielectric material having the value of thermal conductivity at 0.1J/cm.sec.deg. or more can be utilized.

Filed: 1989-08-31
Abstract: PURPOSE: To possibly set change pressure that changes the ratio of opening pressure of an injection nozzle to flow rate from low ratio to high ratio by defining a first and a second paths in a flow control means, having a valve member that closes the second passage while the upstream pressure is below a preset value. CONSTITUTION: A flow control means 14 has a first path 32 that has a control part 33 and a second path 34 that is obstructed only by a control valve assembly 36, the assembly 36 obstructs flow of the path 34 at low pressure. As for the control part 33 and the opening pressure of the assembly 36 (as a change pressure as below), while the engine is in idle operation and the pressure in the path 34 is lower than the opening pressure of the assembly 36, the fuel is supplied at a low rate only through the path 32 to show a good low rate combustion characters. While the engine is at a high speed, fuel pressure in the path 34 becomes higher than the change pressure of the assembly 36, so the fuel flows through both path 32 and 34. Under this condition, the fuel flow is controlled by a spray orifice of nozzle in a normal state.

Filed: 1989-08-30
Abstract: PURPOSE:To enable smooth conveyance of a sample and to improve the precision in measurement by starting takeout of tea leaves only after several or several tens of minutes pass from the start of a crumpling-drying process. CONSTITUTION:When five minutes, for instance, pass after a process is started, upper and lower vibrators 6 and 11, rake-out vanes 20 and an oscillator 16 are operated and takeout of tea leaves by a conveyor 2 for sampling is started for the first time.

Title: Equipment for braking electric motor vehicle
Inventor: UEDA HIROMITSU
IPC: B60L15/20
Filed: 1992-08-24
Abstract: PURPOSE:To ensure a protecting operation by determining that a short-circuit failure occurs in a main rectifier, when an output voltage of the main rectifier becomes a prescribed value or below and a current of a main motor becomes also a prescribed value or below. CONSTITUTION:When both of a voltage relay 13 and a current relay 11 are off for a prescribed time or longer, the current of the current relay 11 becomes small and also the output voltage of a main rectifier 2 becomes small. It is regarded, therefore, that a continuity failure occurs in some of diodes 2A to 2F, and an auxiliary relay 16 is turned on through an on-delay timer 17. When the auxiliary relay 16 turns on, a relay contact 16A turns on while a relay contact 16B turns off, and breaker coils 3 and 6 are demagnetized. Breaker relay contacts 3A and 6A are turned off, an input to a main generator 1 is thereby interrupted and an input to a main motor 4 is also interrupted. Accordingly, a false operation of a short-circuit failure is eliminated and a protecting operation can be ensured.
