Filed: 1999-07-15
Abstract: PROBLEM TO BE SOLVED: To drastically improve the recording speed, and to realize high quality recording without prolongation of the recording time even in the case the number of gradations is large. SOLUTION: A printing cycle T is divided into a plurality of sections T1, T2. Plural kinds of driving voltage wave forms SD1-SD6 are generated according to the size of ink droplets for each of the sections T1, T2. An optional driving voltage wave form is selected from the plural kinds of the driving voltage wave forms SD1-SD6 to be supplied to each of the sections T1, T2 so as to be supplied to a vibration generating means for each of the sections T1, T2. Accordingly, a plurality of gradations can be obtained in the printing cycle T so that the recording speed can be improved drastically as well as a high quality printing image can be obtained without prolongation of the recording time even in the case the number of gradations is large.

Title: Formation of oxide film
Inventor: SHINDOU MASANARI
IPC: B41J2/335
Filed: 1983-10-27
Abstract: PURPOSE:To suppress thoroughly the variance in oxidation of an underlying layer and to decrease the change, etc. of the resistance value thereof by starting formation of an oxide film on the prescribed layer within the specified time from the point of the time when an oxidizing gas is introduced into a film forming chamber. CONSTITUTION:The inside of a vacuum vessel 40 is evacuated down to a prescribed degree of the reduced pressure and while a substrate 3 is heated, Ar and O2 are introduced into the vessel at a specific rate and a high voltage of a high frequency is impressed onto a target (e.g.; high-purity Si target) 41. Glow discharge is thus generated between the target 41 and the substrate 3 and the Si in the target 41 is driven off by Ar<+>, by which alpha-Si is stuck to the substrate 3. The ionized O generated by decomposition of O2 by the glow discharge is brought into reaction with Si at the same instant so that an SiO2 film is deposited on the substrate 3. O2 or oxidizing gas is supplied in the vessel 40 just prior to the start of film formation. More specifically, if the interval between the point of the time when the oxidizing gas is introduced into the vessel and the point of the time when the film formation is started is maintained within 5min, preferably within 1min, the variance in the resistance value of TaN in the underlying layer is considerably reduced.

Then, a triangle EFG formed by the vertex F and its adjacent vertexes E, G is considered, virtual points E', G' are set on the positions of the sides FE, FG respectively separated from the vertex F by length L and an intermediate point P1 of the side E'G' is defined as a pointing-out reference point. After ending the retrieval of the painting-out reference point, a painting-out command based upon the reference point is formed to paint out the plotted polygon.

Title: Hysteresis circuit
Inventor: SEKI KUNIO
IPC: H03K3/02
Filed: 1984-09-28
Abstract: PURPOSE:To adjust easily a hysteresis width by selecting suitably a value of a resistance, in a detecting hysteresis circuit for detecting a power supply voltage and cutting off a power source to a load at an abnormal time. CONSTITUTION:When a power source + Vcc is normal, a transistor Q1 is off, and from the emitter of transistors Q2, Q3 for constituting a mirror circuit, a current I0=2I1 is supplied to an amplifying circuit 1 and the circuit becomes an amplification operating state. When the power source + Vcc rises abnor mally, an on-current flows to the transistor Q1 through a constant-voltage ele ment ZD1, a transistor Q4 also becomes on, this collector current I4 portion is decreased comparing with a current I1 supplied to the transistor Q2, and the transistors Q2, Q3 are shifted to an off-state. Since a current I'1 does not flow, a current I3 increases suddenly, the current I4 increases by a positive feedback operation, the current I0 is cut off, and an amplifier 1 becomes off. By selecting a resistance R1, a hysteresis width by the positive feedback opera tion can be set, therefore, a load circuit can be protected stably from an abnor mality of the power source.

Abstract: PURPOSE:To suppress unnecessary power consumption and to enable cost reduction by operating a switching means according to the discrimination result of the presence of a human body based upon all light beams incident on a sensor from an area to be detected and discriminating human bodies by unit areas. CONSTITUTION:A light converging means 5 which has polarization parts corresponding to the unit areas A - F of the area to be detected is arranged nearby the sensor 3 and light beams from the areas A - F are converted on the sensor 3 through the corresponding polarization parts. Further, a switching means transmits some of the incident light beams from the areas A - F to the sensor 3 selectively and cuts off the other, and switches the transmitted incident light beams in order. A switching control means operates the switching means only after the presence of a human body is discriminated according to all the incident light beams to the sensor 3 to discriminate the presence of the human body by the areas A - F. Thus, only when the presence of the human body is discriminated, the discrimination operation is performed and when there is no human body, the switching means is held in an operation stop state, so that unnecessary power consumption is suppressed.

Filed: 1990-07-31
Abstract: PURPOSE:To dispense with a heating treatment and to facilitate the application of the title shielding material by a method wherein a plastic resin containing a specified amount of superconductive oxide powder is applied and hardened on a basic body. CONSTITUTION:A superconducting magnetic shielding material is manufactured by a method wherein a plastic resin containing 5 to 99wt.% of superconductive oxide powder is applied and hardened on a base body on the basis of a knowledge that when a prescribed amount of superconductive oxide powder is made to disperse in a proper plastic resin, a Meissner effect is shown. As the superconductive oxide powder, Y-Ba-Cu-O powder (critical temperature is 90K.), Bi-Pb-Sr-Ca-Cu-O powder (critical temperature is 110K.), Tl-Ba-Ca-Cu-O powder (critical temperature is 125K.) and the like are applicable. As the plastic resin, any resin, such as silicone resin and the like, is applicable. In the case the content of the powder is less than 5%, a magnetic shielding effect is not recognized and in the case the content exceeds 99% molding becomes difficult. Accordingly, a high-temperature firing for imparting superconductivity characteristics to compound oxide powder as in a conventional method becomes unnecessary.

Title: Method and device for reducing mixture of components in continuous casting of different steel kinds
Inventor: MIYAZAWA KENICHI
IPC: B22D11/116
Filed: 1994-08-29
Abstract: PURPOSE: To reduce the mixture of components at the connecting part of a cast slab, to lengthen the sound part of the cast slab and to improve the yield by arranging a refractory-made molten steel mixture reducing plate for reducing the mixture of the upper molten steel and the lower molten steel in a mold at the lower end of an immersion nozzle. CONSTITUTION: At the time of producing the cast slab by pouring the molten steel 4 in a ladle into the mold 1 through a tundish and the immersion nozzle 2, the molten steel mixture reducing plate 3 is used to reduce the casting speed and straighten the descending flow in the mold 1 by passing through the gap between the solidified shell 6 and the molten steel mixture reducing plate 3. By this method, since the invading depth of the descending flow can drastically be reduced, the component mixture range can be reduced. Further, after completing the pouring of the molten steel in the previous ladle, the casting can continuously be executed without rising the immersion nozzle 2 or reducing the drawing speed of the casting slab.
