Title: Macrominiature sound producer for electronic watch
Inventor: NOMURA HIROO
IPC: G04C21/02
Filed: 1977-12-15
Abstract: PURPOSE: To increase the packing density and thus to increase the information quantity for the electronic watch by forming the vibrating plate into an oval or false oval.  
     CONSTITUTION: The magnetic circuit part comprising electromagnet unit 3 necessary for driving and permanent magnet 4 is formed concentrically centering on magnetic core 1 and then combined with vibrating plate 5 of an oval or false ovalconcentric to the driving system to be stored into the case of the sound producer. With the microminiature sound producer thus constituted, the resonance is produced in proportion to the lengths in the long and short axis of the oval vibrating plate, so at least two major resonant peaks emerge. In other words, the resonance of the low frequency side and the high frequency side are opposed to the long and short axis respectively, so the low frequency reproducing band can be obtained by the effect obtained in the long axis direction. As a result, a large-width reproduction becomes possible, and thus the quantity of information can be increased in such ways that a melody is given to the alarm or the patterns are signified for each interval or the pronunciation.

Inventor: MIYAGAWA SUSUMU
IPC: B41J2/335
Filed: 1987-06-19
Abstract: PURPOSE:To make installation of a partial glazed part needless and to achieve reduction of cost by making preparation by forming a heating resistor on an end slant of a plane glazed part. CONSTITUTION:Only a plane glaze 7b is formed on a surface of a ceramic substrate 1 in a thermal recording head composed of the ceramic substrate 1 which has heating resistor elements 2 and wiring electrodes 6 heat sink, driver IC3, and FPC4, and the heating resistor elements 2 are formed on an end slant of this plane glaze 7b. Since a thin film pattern is thus formed on the end slant of the plane glazed part, the thin film pattern can be prevented from generation of defective inferiority owing to its contact with a photomask. Further, since the thin film pattern is formed not directly on the ceramic substrate 1, defective inferiority of the thin film pattern can be prevented. Preparation of the thermal recording head can be made easy thereby, and reduction of its printing cost can be reduced.

Abstract: PURPOSE:To easily from fixed channel cuts without giving bad influences on an element, by etching grooves selectively on the part wherein an Si3N4 mask is applied on the n-layer on a p type Si substrate and etching-removed, and forming p type layers in the grooves. CONSTITUTION:An n<+> layer 102 is buried onto a p type Si substrate, and an n type epitaxial layer 103 is superposed. After an SiO2 film 105 is etched by an Si3N4 mask 104, the n type layer 103 is anisotropic-etched. A resist mask 106 is applied, grooves 107 are formed on the n type layer 103, and B ions are implanted. Next, the mask 106 is removed, a field oxide film 108 and an oxide film 109 are formed, and simultaneously B ions are activated resulting in the formation of channel cuts 110 which reach the substrate 101 under the field oxide film 108. The stepwise difference on the region 110 is slight. Succeedingly, masks 104, 105 are removed, and an n-p-n bipolar transistor is formed. In this constitution, since the n type epitaxial layer is etched twice, the acceleration voltage when B ion implantation can be reduced, ions do not infiltrate into the element region, and the time of heat treatment can be shortened.

Title: Granular polyolefin material for molding
Inventor: MATSUYAMA NORIYUKI
IPC: C08L33/02
Filed: 1980-10-28
Abstract: PURPOSE: A granular polyolefin material with high bulk specific gravity and good fluidity directly moldable and giving a homogeneous molded product, which is prepd. by providing a layer consisting of a compounding agent and a binder on the surface of a granular polyolefin.  
     CONSTITUTION: A layer consisting of a compounding agent and a binder is provided on the surface of a granular polyolefin of bulk specific gravity ≥0.45 and average particle size 150W2,000μ. One or more finders may be used. A binder of m.p. at least 3°C lower than that of the granular polyolefin is pref. in view of the preparation and molding of the material, so that it is advisable to select the binder in consideration of m.p. of the granular polyolefin. Bulk specific gravity of the granular polyolefin <0.45 is undesirable, because it is impossible to effect sufficient deaeration during molding because of too much clearance within and between the granules. The granular polyolefin of too small a particle size is undesirable because of easy, flyability, while the one of too large a particle size is also undesirable because of poor dispersion of the compounding agent.
