Title: Structure of flange of heat exchanger
Inventor: SHIMOYASHIKI SHIGEHIRO
IPC: F28F9/00
Filed: 1981-01-19
Abstract: PURPOSE:To improve the safety, by welding stretchable bellows of a metal thin sheet into a space in an outer circumference of a flange. CONSTITUTION:A slit 15 having a hight (a) and width (b) is formed in each of an upper flange 1 and a lower flange 3. The strechable bellows 14 of a thin metal sheet are attached with its upper end welded to the upper flange 1 and its lower end welded to the lower flange 13 as shown by the reference numeral 16 to seal the inside of the arrangement from the atmosphere.

Title: Contact of relay
Inventor: KOJIMA KATSUTO
IPC: H01H50/54
Filed: 1992-01-16
Abstract: PURPOSE:To improve stability of a stick-proof property and point-contact resistance by containing pure gold in at least one side contact surface part of a normal open contact couple opposite to each other. CONSTITUTION:In the contact combination of two sets of contact couples of a normally open contact pair 6 and a normally closed contact couple 7, a gold- silver alloy 1 for the surface of the couple 6 while pure gold 1' is used for the couple 7 respectively. Then, the couple 6 side become liable to be influenced by oscillation and impact from the outside in an assembly process to the package of this relay and by oscillation due to ultrasonic washing and an ultrasonic cutter since the contact points are always in contact. Accordingly, the stick- proof strength can be raised by increasing the hardness of one side contacts. Further, since the couple 6 are normally closed, stability of the contact points can be sufficiently held without pure gold while the side of the couple 7 is not required to raise the stick-proof strength since the contact points are normally opened on the side of the couple 7 so that stability of contact resistance can be improved by pure gold.

Title: Bridge structure of piano
Inventor: MAEHARA KAZUO
IPC: G10C3/04
Filed: 1978-01-24
Abstract: PURPOSE: To reduce propagation loss of string vibrations and improve sound quality by so arranging the bridge that the ratio E/ρ of Young's modulus E and density ρ decrease as it goes from the portions in contact with strings toward the portions in contact with soundboard.  
     CONSTITUTION: For example, a long briged 11 is bonded on a soundboard 2 and its shape is identical to that of conventional ones. And the long bridge 11 is bonded and laminated with four members 11a thru d in its thickness direction and the ratios E/ρ of the densities and Young's modulus of the respective members become smaller as it goes from the member 11a on the side in contact with strings toward the member 11d on the side in contact with the soundboard 12. Hence, reflecting of string vibrations by the boundary faces of the member will not occur and the string vibrations are popagated to the sound board, thus the propaation loss is reduced.

Title: Measuring system for phase difference of fm multiplex communication
Inventor: NAKAZAWA SOUICHI
IPC: H04N5/60
Filed: 1980-01-23
Abstract: PURPOSE:To be easy to see zero point of the output signal and increase the accuracy of measurement, by obtaining the difference of each output signal from a band pass filter and delay circuit via a means of the subtractor circuit such as a differential amplifier. CONSTITUTION:The composite signal ei is applied to the band pass filter 12 and delay circuit 13 through the output terminal B of the distributing circuit 11 via the circuit 11. The signal eB passed through the filter 12 receives a phase delay by the delay characteristics of the filter. Thus a delay equivalent to an aforesaid amount is given to the signal ei which is applied to the input terminal of the circuit 13. Then the output signals eD and eB of the circuit 13 and filter 12 are compounded by the substractor circuit 14 to negate the subcarrier wave. Thus the output signal eO containing the zero point is obtained.

Filed: 1993-01-18
Abstract: PURPOSE: To simplify operability and an operation by fitting a drum on a main deck so that it inclines forward and fitting a tension pole so that it can push a tape inside from outside the tape. CONSTITUTION: The tension pole 11 is positioned on the outside of the tape released and outputted from a supply reel 110 and pushes the tape inside. A tension arm to which the tension pole 11 is fitted passes through an unloading stop position ULS and an end sensor position ESP and it is in a state where it is detached to the outer side of the tape while it turns with a hinge part as a center. Thus, the tension pole 11 of the tension arm 26 pushes the tape on the outer side face of the tape 22, and gives tension to the tape with the contact force of a tension band 98 at the time of unloading the tape.

Filed: 1985-01-17
Abstract: PURPOSE:To increase the kind of documents capable of being automatically fed by mounting auxilliary members for paper sheet feed composed of an elastic body coaxially with the shaft of paper feed rollers. CONSTITUTION:When paper sheet feed rollers 4 begin to rotate in a direction shown by an arrow A, the leading edge of a document 1 first touches the trip of a projection of an auxiliary member 8 for paper sheet feed at a contact point 10. Then, when the projection passes through a contact point 9, the docu ment 1 is rolled in the paper sheet feed rollers 3. When an adjacent projection reaches the position of the contact point 10, a force to feed the document 1 is aplied to two positions, i.e., the contact points 9 and 10. The auxiliary mem ber 8 for paper sheet feed is so arranged that one of the projections touches the document 1 at all times, following the rotation of the paper sheet feed rollers 3. The auxiliary member 8 for paper sheet feed is composed of an elastic body. As a result, reliability for feeding documents increases and the documents can be fed even when the paper sheet feed rollers 3 have reduced fricitonal force caused by their stain and the documents cannot be fed without the help of the auxiliary member 8 for paper sheet feed. Namely, the kind of documents available increases.

Filed: 1999-01-13
Abstract: PROBLEM TO BE SOLVED: To obtain N-methylmonoethanolamine and/or N-methyldiethanbolamine with a sufficient reaction speed at a low reaction temperature and without requiring a high pressure reaction vessel by reacting monomethylamine with ethylene oxide in the presence of water. SOLUTION: The objective compounds, N-methylmonoethanolamine and/or N-methyldiethanol amine, are obtained by reacting monomethylamine with ethylene oxide in the presence of water. The molar ratio of water to ethylene oxide is preferably 0.8-4.5. When the molar ratio of water to ethylene oxide is 4.5, the degree of conversion of ethylene oxide is 100% even at a room temperature of 30 deg.C. To selectively obtain N-methylmonoethanolamine, the ratio of monomethylamine/ethylene oxide (molar ratio) is high. It is not necessary to use a reaction solvent and it is better to use no reaction solvent. As types of reaction, both of a batch reaction and a continuous reaction can be applicable.
