IPC: C21C7/072
Filed: 1997-01-08
Abstract: PROBLEM TO BE SOLVED: To prevent penetration of molten lead and steel even in the case of a low viscosity steel such as a lead free-cutting steel and to enable a stable gas blowing by providing the gap having a specific size between the outer periphery of a plug and a side surface iron shell. SOLUTION: In this plug for gas blowing, a close refractory outer peripheral part groove (gap) 2 of 0.08-0.3mm is provided between the plug close refractory main body 1 and the side surface iron shell 3. The plug main body 1 is composed of the close refractory through which gas is not passed, and the outer peripheral part groove (gap) 2 is formed between the plug body 1 and the side surface iron shell 3 by forming the groove on the outer peripheral part. At the time of operating, the gas is blown from this outer peripheral groove (gap) 2. By this constitution, if the lead and the molten steel intend to permeaste, the heat is absorbed into the side surface iron shell 3 and these metals are solidified and the permeation is prevented.  To the size of the outer peripheral part groove (gap) 2, in the case of being <=0.08mm, the blowing gas quantity is insufficient and in the case of >=0.3mm, the fear of the permeation of molten steel, etc., is developed.

Title: Manufacture of transistor
Inventor: IITAKA YUKIO
IPC: H01L21/331
Filed: 1983-01-28
Abstract: PURPOSE:To obtain a transistor without the decrease of current amplification factors even when emitter current increases by a method wherein the junction surface between an emitter and a base is formed in wave form, and, in order to form it, first an emitter impurity is evaporated in island form on the base surface, next the island form impurity is joined by heat treatment, thus forming the junction surface between the base and the emitter in wave form, when a transistor is manufactured. CONSTITUTION:The base region 2 is diffusion-formed in the surface layer of a semiconductor substrate 3 serving as the collector region, and the dotted emitter impurity 4 is deposited thereon in island form. At this time the interval of the impurity 4 is kept approximately the same as the final emitter diffusion depth. Next, emitter diffusion is performed, and thus the boundary surface between the emitter region 1 and the base region 2 generated is formed in wave form or a wave form approximate thereto. In such a manner, the junction area between the emitter and the base increases, and the current density reduces; therefore, even when the emitter current increases, the current amplification factor does not decrease.

IPC: G02B6/293
Filed: 1979-02-07
Abstract: PURPOSE:To obtain the photo branching and coupling device of less insertion losses and crosstalk free from wavelength aberrations by using optical fibers, plane diffraction grating and concave reflecting mirror, in an optical communication system. CONSTITUTION:Optical fibers 1 consists of the 1st fiber which transmits light signal of plural wavelengths and plural optical fibers which transmit the specific wavelength light signal. The end part of the fibers 1 is disposed near the focus of a reflecting concave mirror 2. Now, the light containing multiple wavelengths emitted from the fibers 1 is reflected by the mirror 2, is diffracted by a diffraction grating 3, again returns to the mirror 2 and is received in the plural optical fibers with a slight change in position by each wavelength, whereby branching is completed. As a result of this, no wavelength aberrations exist because no lenses are used. In addition, the wavelength differences among channels may be taken smaller and crosstalk reduced as well.

Abstract: PURPOSE:To decrease the number of transistors (TRs) constituting the titled flip-flop by adopting the constitution that an input gate of a half latch circuit is replaced into a gate circuit switched by the 1st and 2nd clock signal (2-phase clock signal). CONSTITUTION:An input signal D passes through a gate circuit 43 comprising MOSTRs 27-32 for DELTAt. The DELTAt in this case is a sufficiently long time when an output signal Q of the gate circuit 43 is made stable by the input signal. The signal Q is stored by a stray capacitance in existence from an output region of the gate circuit 43 to the input region of a latch circuit 44 comprising MOSTRs 33-38 during a time (1/2T-DELTAt) except DELTAt while the level of a clock signal X is at a low level voltage. The 1/2T-DELTAt is a sufficiently short time when the Q keeps a stable level by the stray capacitance. Then the signal Q is stored in the latch circuit 44 when the clock signal X goes to a high voltage level and this state continues until the X reaches a low voltage level.
