IPC: B41J21/00
Filed: 1996-08-02
Abstract: PROBLEM TO BE SOLVED: To improve a using efficiency of a receiving buffer by comparing the quantity of data to be transferred next with a idle capacity of the receiving buffer to decide a busy state of the buffer. SOLUTION: The transmitting data 100 to 103 stored in a transmitting data buffer 11 of a transmitting module 1 are successively transferred to a receiving module 2 and stored in a receiving buffer 21.

Title: Sliding material
Inventor: HAMASAKA NAOHARU
IPC: C22C9/02
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To obtain a sliding material excellent in corrosion resistance to biodegradable oil and having superior conformability to a mating material by specifying respective contents of Sn, Pb, Ni, and Zn in a lead bronze type material. SOLUTION: This sliding material has a composition consisting of, by weight, 9.0-15.0% Sn, 8.5-11.0% Pb, <=3% Ni, 3.0-10.0% Zn, and the balance Cu. In this composition, Sn content in the amount not lower than the lower limit is necessary to strengthen the crystallization of Cu and also Sn content is regulated to a value not higher than the upper limit in order to allow Sn to enter into solid solution perfectly in Cu. Although it is necessary to regulate Pb content to a value not lower than the lower limit to secure machinability, Pb is regulated to a value not higher than the upper limit because Pb is liable to lower strength (hardness) with the increase of its content. Zn is necessary to improve corrosion resistance, and the effect becomes remarkable when Zn content is not lower than the lower limit, and, when it exceeds the upper limit, Zn is liable to be zinc oxide and the probability of occurrence of material defects is increased. Although Ni can prevent the segregation of Pb and contribute to the improvement of strength, hardness is increased and conformability to a mating material is reduced when its content exceeds the upper limit.

Abstract: PURPOSE:To prevent current fluctuation due to light absorption in an active region and to improve stability in operation, by forming a forbidden band with of the active region in a transistor element so that its energy is larger than energy of photons radiated from a luminous element. CONSTITUTION:On a semi-insulating GaAs element 1, a laser element LD is composed of the following units: a n-type GaAs contact layer 12, a n-type AlxGa1-xAs(x=0.3) clad layer 13, a non-doped GaAs active layer 14, a p-type AlxGa1-xAs(x=0.3) clad layer 15, a p-type GaAs contact layer 16, a n-side electrode 17, and a p-side electrode 18. Similarly on the substrate 1, a MES FET element is composed of the following units: a n-type AlyGa1-yAs channel layer 2, a source.drain electrode 3, and a gate electrode 4. This n-type AlyGa1-yAs channel layer 2 is formed to have an Al composition ratio of e.g., 0.4 and forbidden band width of about 1.92 eV, so that energy of photons in the band width is larger than that of photons in forbidden band width nearly of about 1.42 eV of the GaAs active layer 14 in the laser element LD. Thus, even if light radiated from the laser element is scattered to become incident to the channel layer 2, current fluctuation due to light absorption in the MES FET element is prevented, so that stable light output can be obtained.

Since the volume of the raw gases is rapidly reduced as the reaction proceeds, an upward gas current is formed, and the descent of powder is disturbed. The powder stays in the air until the powder is sufficiently grown. The settled metallic titanium powder forms a slurry with liq. magnesium chloride and is discharged outside the reactor 1. The slurry is passed through a separator 10 and separated into the metal powder as the product and magnesium chloride. The magnesium chloride is returned to an electrolytic furnace 5.

Title: Image processing unit and its method
Inventor: HONPO TSUNAO
IPC: H04N1/407
Filed: 1996-08-22
Abstract: PROBLEM TO BE SOLVED: To prevent the linearity between image data and a pulse width even when the pulse width is made narrower and to prevent a density change at a highlight part of an output image from being unnatural. SOLUTION: A triangle wave generating section 108 generates a triangle wave synchronously with a clock whose period is twice that of an image clock 103. Buffers 104, 105 are used to convert an image signal into a pair of image signals having a symmetrical voltage distribution based on a voltage being a half of the amplitude of the triangle wave. A comparator 106 compares the triangle wave with an output of the buffer 104, and a comparator 107 compares the triangle wave with an output of the buffer 105. An EXOR(exclusive OR) gate 116 applies exclusive OR to both the results of comparison and provides an output of a laser drive signal with a pulse width proportional to image data 101.
