Title: Semiconductor epitaxial wafer and its manufacture
Inventor: YOSHINAGA ATSUSHI
IPC: H01L21/208
Filed: 1989-12-22
Abstract: PURPOSE:To control unevenness on a surface for growing in a simple manner to obtain an epitaxial wafer having a substantially uniform growing surface by providing an epitaxial growing layer having a plane orientation shifted by a specific angle from a (-1-1-1) surface of a single crystal. CONSTITUTION:An epitaxial growing layer having a plane orientation shifted by 0.5 to 2 degrees from a (-1-1-1) surface of a single crystal is provided. The single crystal is cut in a surface shifted by 0.5 to 2 degrees from the (-1-1-1) surface and a semiconductor crystal layer is epitaxially grown on the cut surface. For example, with a CaP single crystal base used an off-angle base having a plane orientation shifted by 0.7 degree from the (-1-1-1) surface is used to epitaxially grow a nitrogen doped CaP layer. Thus a frequency of unevenness on the growing surface is smaller than a device size so that it is possible to obtain a semiconductor device with a fluctuation in characteristics reduced among devices caused by the unevenness.

Title: Magneto-optical recording medium
Inventor: KARUBE HIROO
IPC: G11B11/10
Filed: 1989-12-22
Abstract: PURPOSE:To increase the Kerr rotation angle by incorporating at least one element selected from Pb, P, As, Sb, and Bi into layers composed of one or more 3d transition metals which are alternately laminated with rare earth metal layers. CONSTITUTION:At least one element selected from Pb, P, As, Sb, and Bi is incorporated into the layers 3 composed of one or more 3d transition metals which are alternately laminated with layers 2 composed of one or more rare earth metals. The rare earth metals are, for example, Tb, Y, La, Ce, Pr, Nd, Sm, Gd, Dy, etc., and the 3d transition metals are Fe, Co, Ni, etc. The effect of addition is varied depending on the kind of the rare-earth elements. On the other hand, the Kerr rotation angle for light of longer wavelength than 600 nm largely depends on the contribution of the transition metals (such as Fe, Co). Therefore, the additive elements are made to couple only with the transition metal elements, separating from the rare earth elements. Thus, the Kerr rotation angle can be increased.

Title: Seal
Inventor: UYAMA HARUO
IPC: G09F3/02
Filed: 1993-12-27
Abstract: PURPOSE:To provide a seal for preventing forgery, difficult to discriminate the layer constitution or the structural materials and having an unique color tone capable of discriminating authenticity and a seal for optically preventing forgery, satisfying requirement for the seal for preventing forgery and obtained by laminating a ceramic capable of transferring to a stereoscopic material such as a molding. CONSTITUTION:The seal is obtained by providing a functional layer 3 on a substrate 2 and laminating an adhesive layer 4 on the same surface side or another surface side and the functional layer 3 is obtained by laminating plural ceramic materials different in refractive index. And the seal has a property capable of reflecting or transmitting the light in a specific wavelength region by constituting the functional layer 3 so as to alternately laminate the ceramics of a low refractive index layer 7 and a high refractive index layer 6 and exhibits a different color by changing the angle to observe because the thickness of the functional layer is changed to shift the wavelength region. As a result, the authenticity is easily discriminated.

Title: Stringed instrument with device for sound volume intensification and bass reproduction
Inventor: GOTTSCHALL PETER
IPC: G10D3/02
Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To improve and intensify the sound level and regeneration of a bass of a stringed musical instrument without any need to enlarge a resonance body by inserting at least one intermediate resonance board in the resonance body in such a state as inclined toward a resonance cover. SOLUTION: An intermediate resonance board 19 is inserted in a resonance body 3 in such a state as inclined toward a rear board 7 and a resonance cover 5. This resonance board 19 covers only a part of a section across a lateral board ring 9. The lateral ring board 9 expands into the internal space of the resonance body 3 and divides the space into two spaces 21 and 23 connected to each other. In this case, the resonance cover 5 is vibrated by use of the known way via a bridge 15 while a string 13 is being plucked or rubbed with a bow, thereby directly emitting a high level of sound externally by the ordinary method and by the same sound quality. The frequency of a low level of sound, on the other hand, is emitted to the inside of the resonance body 3 and first intensified via the upper space 21.  Then, the frequency enters the lower space 23 via a connected position 27 toward an arrow P direction, or is externally emitted via a sound hole 17 at the end of the lower space 23.

Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To improve the pattern design used for processing an integrated circuit by a method wherein the additional lines and the working lines to be formed on a semiconductor wafer have the equal surface region of conductive material with each other. SOLUTION: The distance in horizontal direction between the operating lines 2 and 3 exceeds the threshold distance X, and the distance in horizontal direction between operating lines 5, 6 and 7 and operating lines 8, 9 and 10 exceeds the threshold distance Y. As a result, dummy lines 11 to 16 are printed in a region 17 in order to guarantee the uniform printing of all operation lines. In order to guarantee the desired uniformity in the load for the patterning conducted for formation of both operation lines and dummy lines, a patterning operation is conducted on the single layer, consisting of conductive material, where both operating lines and dummy lines are formed, and the operation lines and the dummy lines are formed with the same material.

Thereafter, provided is the process in which by implanting impurity ions of a high concentration into the silicon substrate 1, junctions 12, 15 are formed. Thereby, the channeling, which is caused when thereafter implanting ions, can be prevented, and since crystal defects in silicon can be terminated, the dangling bond of the defects, which causes the generations of leakage currents, can be reduced.

Title: Recording head of ink-jet recorder and recording head cartridge comprising said recording head
Inventor: KAWAI JUN
IPC: B41J2/05
Filed: 1994-12-21
Abstract: PURPOSE: To eliminate uneven density caused by differences in temperature-rise characteristics of recording heads by a method wherein a heating element substrate is bonded on a support member by a thermally-conductive adhesive layer to stabilize the temperature-rise characteristics of the recording heads. CONSTITUTION: A heater board 100 is bonded on a support member 300 by a thermally-conductive adhesive 101 to form an ink-jet head. Right and left reference studs 2500 and 2600 are references for mounting a carriage that carries a head. A represents the thickness of the adhesive layer 101 and B shows a distance from the upside of the heater board 100 to the reference studs 2500 and 260. When an ink-jet head unit is assembled to perform recording, the heater board 100 as a spouting pressure generating part becomes high temperature due to the thermal energy for spouting. Therefore, to avoid heat accumulation only in the heater board 100, the heater board 100 is bonded on the metal support member 300 having a large heat capacity by the thermally-conductive adhesive 101 to dissipate heat and cool the heat board 100.
