Title: Multitubular type heat exchanger
Inventor: SAKATA YUJI
IPC: F28F9/013
Filed: 1987-11-18
Abstract: PURPOSE:To improve the assembly workability and heat transfer performance by using as a heat transfer tube support member a shape memory alloy which has a large interval with a heat transfer tube at the time of assembling the heat transfer tube and a part of which tightly adheres to the transfer tube at the time of operating the same. CONSTITUTION:A shell body 1 is provided with a shell side inlet nozzle 2 and a shell side outlet nozzle 3. Tubular plates 4 are provided at both ends of the shell body 1, and heat transfer tubes 5 are disposed between both tubular plates. The heat transfer tubes 5 are provided with heat transfer tube support members 6 at a suitable interval. The heat transfer tube support members 6 are supported by rings 7. As each heat transfer tube support member, a shape memory alloy is used which is in a shape of being inserted between the heat transfer tubes, and which has such a characteristic that it contracts at low-temperature time and elongates at a high-temperature time. The assembly of the heat transfer tube is carried out under the condition of room temperature. At time of operating, the temperature of a shell side fluid becomes higher than the room temperature. Accordingly, the assembly work of the heat transfer tube becomes facilitated. At the time of the operation, the heat transfer tube is supported by the support member and an action to disturb the flow of the shell side fluid becomes large. Therefore, the heat transfer performance is improved.

Title: Production of optical thin film
Inventor: KAWAMATA TAKESHI
IPC: G02B1/10
Filed: 1994-11-24
Abstract: PURPOSE: To produce an optical thin film of high quality at a low cost by using a single crystal Si target to produce the thin film. CONSTITUTION: In the production process of an optical thin film, a single crystal Si target is used to form a SiO2 film by reactive sputtering in the environment into which at least two kinds of gases of a gas containing oxygen and an inert gas are introduced while impressing pulses of positive voltage on a DC power source. In this method, the resistance of the single crystal Si target is specified to <=10mΩ.cm. By this method, since no intergranular interface is present in the crystal different from a polycrystalline target, the surface roughness of the target is not increased. Therefore, arc discharge is hardly caused. The target has excellent uniformity in the target surface, and as a result, even when a film is formed on a large substrate, the film quality shows higher uniformity.  By impressing pulses of positive voltage on the DC power source, charges hardly accumulate on the surface of the target.

Abstract: PURPOSE:To easily and surely couple the nerve cells by setting a pair of electrode needles so as to insert and hold a pair of nerve cells to be coupled by the control of an electrode control means, while observing the nerve cells to be coupled by an observing means. CONSTITUTION:By fixing a living body to a work table, and adjusting magnification and a focal distance of an optical lens 21, a position on a frame 24, etc., a work part of the living body is observed by a TV monitor 23. Subsequently, by operating a manipulator 25, a first electrode 11 and a second electrode 12 are thrust into a prescribed position of a living body tissue, and also, a stimulation electrode 31 and a monitor electrode 32 are thrust into one and the other end parts of the nerve cells to be coupled. Next, by applying a DC voltage between the electrode 11 and the electrode 12, a minute current is allowed to flow into the living body. Also, while the minute current is flowing, an electric stimulation is given to the living body through the stimulation electrode 31 from a pulse generator 33 at a prescribed time interval, and its reaction is observed by an oscilloscope 34 through the monitor electrode 32. In such a state, when a reaction to the stimulation appears, it is decided that the cell coupling is completed, and the voltage application to the electrode 11 and the electrode 12 is stopped.

Title: Production of ferrous sliding member
Inventor: ASAI YASUSHI
IPC: C21D8/00
Filed: 1988-11-15
Abstract: PURPOSE:To impart the coefft. of thermal expansion approximate to the coefft. of thermal expansion of an Al alloy to the sliding member and to improve the wear resistance of the sliding member by subjecting the sliding member to an austemper treatment and subjecting the sliding surface to shot peening. CONSTITUTION:The sliding member made of a cast iron is subjected to the austemper treatment to form the structure contg. 50% residual austenite. The sliding surface of this sliding member is subjected to the shot peening at 0.05 to 0.2mm short grain diameter. The transformation of the residual austenite to martensite is suppressed to a lower level in this way and the high surface hardness and sufficient wear resistance are assured. Since many fine recesses are formed on the sliding surface, the sliding characteristic by an oil reserving effect is improved. This sliding member is applicable to all members which make fitting and sliding with the mating member of the Al alloy.

Inventor: SHIROYAMA HIDEKI
IPC: B25G1/00
Filed: 1999-10-12
Abstract: PROBLEM TO BE SOLVED: To provide a slip stopper mounted to a grip of a knife and the like so as to prevent a slip suitably. SOLUTION: This slip stopper 1 is formed when a plurality of through holes 2 penetrating in the depth direction are formed in a thermally shrinkable tubular surrounding part 1a. When this grip 4 of the knife 3, for example, is inserted into the slip stopper 1 and they are heated to be thermally shrunk, the stopper 1 is mounted in the outer circumference of the grip 4. In this mounted condition, stepped faces in the circumferences of the holes 2 stick onto the palm of a hand gripping the stopper 1, so that slip stopping effect can be provided suitably. Although the slip stopper is thin in thickness, it gives desirable slip stopping effect, so that a gripping feeling on the grip 4 is hardly deteriorated and a user can handle the knife finely, and consequently, usability is improved.

Title: Vegetation base material and slope stabilizing construction method using this material
Inventor: TAKANO TASABURO
IPC: E02D17/20
Filed: 1994-10-31
Abstract: PURPOSE: To provide a slope stabilizing construction method and vegetation base material which is light and excellent in water retentivity, and suitable for growing up a plant and moreover facilitate the execution of work in a field by mixing a light- weight aggregate being less than fixed specific gravity and the seeds of the plant with culture soil, and closely spreading vegetation base material solidified with a combining agent on the surface of slope enclosed through lattice-shaped slope frames. CONSTITUTION: A light aggregate such as a styrene foam grain or the like and the seeds of a plant are mixed with a culture soil, and solidified into a block-shape or a plate-shape with a combining agent. In this case, the specific weight of the styrene foam grain is set up less than 1. In addition, the grains are mixed to 40vol.% and a grain diameter is set up as 2-8mm. The vegetation base material therefore becomes rich in water retentivity and permeability and improves the growing up of a root of the plant. The vegetation base material 12 is closely spread on the ground partitioned by a parallel crosses-shaped block wall 10 or lattice-shaped slope frame on an oblique face 11. Thus since the vegetation base material having uniform quality can be obtained by shop fabrication, field execution becomes extremely easy, and the term of execution can be sharply shortened.

IPC: G10H7/00
Filed: 1988-11-17
Abstract: PURPOSE:To reduce the memory capacity of an electronic musical instrument by setting flags to tones which are not required for changing their waveforms in the high pitch direction and tones which are not required for changing their envelope shapes in the high pitch direction to zero. CONSTITUTION:This electronic musical instrument has WTABs, ETABs, W flags, and E flags which are different at every tone in the control table 21 of a key scaling section 15 and it is not required to secure a corresponding waveform memory selecting data memory about a tone which are not required for changing the waveform in the high pitch direction, because the WTAB becomes waveform memory selected data when the M flag is set to zero. In addition, it is not required to secure a corresponding envelope memory selecting data memory about a tone which is not required for changing the envelope shape in the high pitch direction, because the ETAB becomes envelope memory selecting data when the E flag is set to zero. Therefore, the memory capacity can be reduced.
