Filed: 1981-08-18
Abstract: PURPOSE:To make it possible to manufacture a mesa semiconductor device which is excellent in uniformity and characteristic stability and low in cost, by including the steps of forming a selective coating of a corrosion-resistant wax by means of a screen printing, applying onto the selective coating a thick film of the above-mentioned corrosion-resistant wax having a pattern a size smaller than that of the selective coating, and then melting the corrosion-resistant wax by heating. CONSTITUTION:An oxide film 2 is formed on the surface of a semiconductor substrate 1 by thermal oxidation or the like. Moreover, a pattern is formed by a selective etching. Then, a wax 3 is selectively deposited thereonto by a screen printing, and a wax thick film 4 is arranged in the center of the wax 3. The wax 3 and the wax thick film 4 are united together on heating. With the uniform corrosion-resistant wax film used as a mask, a mesa groove part is etched to form a groove 5. By this method, an essential unetched part of the semiconductor device has no part thin in coating and no pinhole at all, and the wax thick film may be smaller than that in the conventional application method.

Title: Ink jet recording device and method
Inventor: GOTOH FUMIHIRO
IPC: H04N1/40
Filed: 1993-05-31
Abstract: PURPOSE:To reduce the unevenness of density by overlapping inks with different densities each other by a method wherein density data are N-ary coded per pixel and one ink, which corresponds to the N-ary coded value on each pixel among n-1 kinds of different densities of same color-based inks, is jetted. CONSTITUTION:Respective color processings are applied in a masking circuit 40 and an under-color removal and black forming circuit 41 to original image density signals Y1, M1 and C1 in order to produce image density signals Y36, M36, C36 and K36. Further, in a gamma-correcting circuit 42, gamma-correction is performed so as to input obtained image density signals Y37, M37, C37 and K37 in a ternary coding circuit 53 in order to ternary code the multivalued density signals Y37, M37, C37 and K37 in 0, 0.5 and 1. After that, when the ternary coded value is 0, the jetting signals of deep and light inks of respective colors are made to be 0. When the ternary coded value is 0.5, the jetting signals Yu48, Mu48, Cu48 and Ku48 of light ink are made to be 1. Further, when the ternary coded value is 1, the jetting signals Yk48, Mk48, Ck48 and Kk48 of deep ink are made to be 1 during printing.

Title: Loudspeaker
Inventor: INANAGA KIYOFUMI
IPC: H04R23/00
Filed: 1988-05-26
Abstract: PURPOSE:To obtain driving force which corresponds faithfully to a sound signal by making height of one of a conductive part of a diaphragm and a feeding coil higher than height of the other. CONSTITUTION:A diaphragm 2 of a dome type consists of a vibration part 15 which has been formed in a hemispherical shape, and a conductive part 8 which has been formed annularly in an opening edge part 7. This diaphragm 2 is supported so as to be freely vibratable by a damper 9, in a state that the conductive part 8 is positioned in a magnetic void part 10. Also, the conductive part 8 is formed further extending over the lower part. This conductive part is constituted so that even if the diaphragm 2 moves forward and backward greatly in accordance with an induced current, the conductive part 8 is always left extending over the whole range of a DC magnetic field of a uniform magnetic flux distribution. In such a way, in the conductive part 8, an induced current corresponding faithfully to a sound signal is induced, and on the other hand, since strength of the DC magnetic field is not varied either, driving force corresponding faithfully to the sound signal is obtained, and the linearity between the sound signal and the amplitude of the diaphragm 2 can be maintained.

Title: Automatic sound volume controller
Inventor: SAKAKIBARA TAKASHI
IPC: G11B20/04
Filed: 1982-07-23
Abstract: PURPOSE:To ensure effective control of sound volume without giving masking at a low level nor generating an excessive degree of sound volume at a high level even to a music signal having a big level change, by performing automatic gain control not only to the ambient noise level but also to the input signal level. CONSTITUTION:When an ambient sound level detecting circuit 2 supplies the output signal of a sensor 1, the DC voltage is delivered in proportion to the level increase DELTANdB with respect to the reference sound level NodB(A) SPL. While the level of the input signal supplied to a signal input terminal 3 is detected by an input signal level detecting circuit 8. Then the DC voltage proportional to the rise DELTASdB to the reference signal level SodBs is delivered. An adder circuit 11 adds the voltage corresponding to a negative constant DELTASdB to the output of a multiplier circuit 10' and supplies them to a gain controlling circuit 5 via a limiter circuit 13. Thus the sound volume is gradually increased from a low signal level so as to receive no masking to the increase of the ambient noies.

IPC: G11B7/135
Filed: 1993-05-07
Abstract: PURPOSE:To realize an optical pick-up device using the astigmatism method at a low cost and in a small-sized and to improve the accuracy of detecting focussing error and tracking error. CONSTITUTION:A luminous flux passed through a detection line 7 is divided into two luminous fluxes La, Lb by a beam splitter 8, the luminous flux La, one of them, is extracted only at a center part by an aperture members 20. The center part luminous flux Laa passed through the aperture members 20 is made incident on a quadripartite photo-detector 10 in a state where the astigmatism is given to the Laa via a cylindrical lens 9. And, another luminous flux Lb is made incident on a bisected photodetector 11. Consequently, the patterns of the 1st-order diffracted light of focussing components are not made incident on the quadripartite photodetector 10 since the luminous flux Laa passed through the aperture members 20 includes only the patterns of the center part. Thus, a focussing servo control is excutede stably since track traversing noise is not superimposed on a focussing error signal.
