Title: Pneumatic tire with improved heating property
Inventor: OGAWA MASAKI
IPC: C08K3/04
Filed: 1978-04-06
Abstract: PURPOSE:To greatly reduce heating and improve the wear-resisting property, by using a tread base rubber mixed with a prescribed quantity of syn-1,2-polybutadiene short fibers. CONSTITUTION:The maximum diameter of the syn-1,2-polybutadiene short fibers is 10mu. Syn-1,2-polybutadiene grains of 10 to 700 mu in diameter are mixed with an unvulcanized rubber at a temperature not higher than 190 deg.C. The mixture is extruded through a circular die of 1 to 5mm in inside diameter and 1 to 20 in rotio of length to inside diameter. The extruded mixture is cooled and extended by rolls, thereby obtaining a master batch wherein the syn-1,2-polybutadiene short fibers are dispersed. Because the short fibers are firmly bonded to the rubber, the rubber  is prevented from creeping. Therefore, a high resilient elasticity and a high reinforcing property are obtained.

Abstract: PURPOSE:To prevent an undersired wave which is excited by an electric field caused between a non-grounding electrode finger and ground from giving adverse effect on the characteristic of a surface acoustic wave device by decreasing the area occupied by an electrode digit connecting to a non-grounding side bus bar. CONSTITUTION:A bus bar 4 connecting to an interdigital electrode having a larger sum of areas of electrode digits 6 and 7 prolonged from a bus bar 2 and from a bus bar 4, that is, to the interdigital electrode of the electrode digits 7 is connected to ground, and the bus bar 2 connecting to the interdigital electrode having the smaller sum of areas connecting to the electrode digits 6 is connected to an input output terminal 1. Similarly, the bus bar 3 connecting to the cross electrode having a larger sum of areas of electrode digits connects to ground and the bus bar 5 connecting to the interdigital electrode having a smaller sum of areas of electrode digits is connected to the input output terminal 1. Since the electrode pattern is split and connected to decrease the occupied area of the electrode digits connecting to the input output terminal 1 is decreased, the adverse effect of an undersired wave excited by an electric field cased between the electrode digits connecting to the input output terminal 1 and a stem 8 at a ground level is reduced.

Abstract: PURPOSE:To clearly measure the recording state of a vertical magnetic recording medium by using a cantilever consisting of a probe and a leaf spring where a hard magnetic thin film is formed at the tip as the cantilever for magnetic force microscope. CONSTITUTION:A stainless steel foil 1 is machined in the shape of a leaf spring 2 and then a probe 3 is adhered to the tip of the leaf spring 2. In the probe 3, iron/cobalt alloy thin film 5 is formed on the surface of an iron probe 4 which is machined in needle shape by performing electrolytic polishing of iron wire by the electrolytic plating method. The iron/cobalt alloy is a hard magnetic material and has a large coercive force so that the direction of magnetization of the probe 3 is constantly maintained to be fixed and attraction and repulsion operate according to sample magnetization direction for the probe 3 when the sample 3 is brought closer to the sample surface and scans the sample surface in parallel. When the probe 3 is moved slightly up and down by a piezoelectric element and scans the sample surface in parallel in this state, the probe 3 is controlled in upper position when the magnetization is in the same direction. On the other hand, when the magnetization is in opposite direction, the probe 3 is controlled in lower position. It is changed into an image, thus measuring the magnetization distribution of the sample.

Abstract: PURPOSE:To facilitate the formation of fine element isolation regions, by providing the process of forming a single crystal semiconductor layer on a substrate, and a polycrystalline semiconductor layer on the oxide film and the process of converting the latter layer into an oxide film by utilizing the difference in oxidation speed. CONSTITUTION:The surface of a Si semiconductor substrate 11 is exposed at element forming regions by selectively etching away the part other than the element forming regions, and a Si single crystal epitaxial layer is grown over a Si oxide film 21 and the substrate 11. The oxidation speed is higher in a polycrystalline Si layer 24 than in a single crystal Si layer 23. Since the former layer 24 gets higher speeds in the longitudinal direction and lower speeds in the lateral direction, on oxidation treatment after the growth of the Si single crystal epitaxial layer, the layer 23 is left thick enough, and the layer 24 is entirely oxidized and can be converted into a Si oxide film 25 as an element isolation region. The oxide film formed at the next step is etched away, and a Si oxide film 25 as the element isolation region is formed.

Abstract: PURPOSE:To improve the working efficiency of a worker by performing control to comfortable warm heat environment through detection of a comfortable condition desired by a worker. CONSTITUTION:In automatic control of warm heat environment of a working area, where a seating work or a work in a fixed place similar to the seating work is performed, by means of heat source devices, the presence or the absence of a worker in a working area is detected by using a human body detector employing an infrared ray sensor 7, and an atmospheric temperature is detected by an ordinary temperature detector 5.

IPC: G03G21/00
Filed: 1982-03-17
Abstract: PURPOSE:To obtain a more reliable jam detector, by not judging as jam when 2 states of paper presence and paper absence occur at the interval of one pulse of a reference pulse, and ensuring detection of the state between the pulse. CONSTITUTION:A paper presence flag FF1 and a paper absence flag FF2 are  each a memory for clearing preceding data and storing a new jam sensor signal. When each of the flags FF1, FF2 puts out ''1'', the paper is normally carried. An NAND gate G2 puts out ''1'' level, and does not put out a jam signal, but when FF1, FF2 are each not the above case, an NAND gate G1 puts out ''1'' level output. At that time, a timing signal is provided from a timing signal generating circuit IC1, and when all the conditions are changed to favor generation of ''1'' output from an inverter I2, the NAND gate G2 provides ''0'' level output, therefore, an inverter I1 provide ''1'' level output, that is, a jam signal.
