IPC: E06B9/01
Filed: 1998-08-18
Abstract: PROBLEM TO BE SOLVED: To provide a beautiful outlook and a superb strength without cutting restrictions and enable a painting work to be performed easily using a machine by applying an adhesive in the center part of an intersecting groove and nipping a panel body between a weight platen and a receiving platen and further applying a weight to the panel body, so that the adhesive is spread widely by a pressure contact force generated by the weight and the intersecting grooves are bonded together. SOLUTION: When a wood cross lattice is assembled, a front cross support 1 and a back cross support 2 are not flush with both first and second surface respectively but the front cross support 1 protrudes slightly ahead of the back cross support 2 on the first surface and contrarily the back cross support 2 protrudes ahead of the front cross support 1 as a projecting part T on the second surface. During assembling, a little amount of adhesive 5 is applied in the center of the bottom face of an intersecting groove 3 and the cross supports 1, 2 are assembled and weighted. In this case, both cross supports 1, 2 are nipped between a broad platelike receiving platen 5 and a weight platen 7, so that the receiving platen 5 comes into contact with the one cross support 2 and the weight platen 7 comes into contact with the other cross support 1.  Consequently the bottom faces of the intersecting grooves 3, 3 are brought into contact with each other under pressure and the adhesive 5 is spread to display an adhesive capability to the maximum possible extent.

Abstract: PURPOSE:To ensure the insertion of a shutter by forming a slit at a case side edge part to divide a guide groove and also an elastically deforming part which has an elastic deformation by the pressure of a hook projection of the shutter at the divided side edge part. CONSTITUTION:A slit 12 extending up to a guide groove 6 from a case side edge 9 is formed at a part of a side edge part 4 of a lower case 1b to divide the groove 6. Then the groove 6 is cut partially to form an elastically deforming part 10. A shutter is pushed inside from the front side of cases 1a and 1b, and a hook projection 5 of the shutter presses the part 10 toward a lower space 17 to deform the part 10. Thus the projection 5 is put into the groove 6. In this case, the part 10 is changed again into its original form to function as a hook projection of the projection 5. Thus the projection 5 is prevented from being dropped off from the groove 6. Furthermore the part 10 has a tapered form 16 at its tip to facilitate easy insertion of the projection 5.

Title: Sonic wave delay line
Inventor: RIHIARUTO ZORUTONAA
IPC: H03H3/08
Filed: 1989-09-07
Abstract: PURPOSE: To delay an electric signal in a frequency area of 1 to 10MHz by the conditions of a wide band, a small transmission loss, no distortion, and narrow traveling time tolerance by setting up the thickness of a substrate to a value less than the wavelength of the maximum transmission frequency and polarizing the substrate almost in parallel with equal potential lines. CONSTITUTION: In a sound delay line 2 constituted of a piezo-electric ceramic material and arranging electroacoustic converters 6, 8 on a substrate 4 with an interval of length L so as to mutually form a traveling time route as electrode structures, the electrode structures of respective converters 6, 8 are together formed on one face or both the faces of the substrate 4. The length (d) of the substrate 4 is set up to a value less than the wavelength of maximum frequency to be transmitted through the substrate 4 and the substrate 4 is polarized almost in parallel with equal potential lines generated at the time of impressing voltage to the electrode structures in the substrate 4. Namely the thickness (d) is set up to 100 or 200μm when upper limit frequency is 10MHz so that the electric signal can be delayed without generating distortion over a wide range.  Consequently the sound wave delay line can delay an electric signal in the frequency area of 1 to 10MHz by the conditions of the wide range, a small transmission loss, no distortion, and narrow traveling time tolerance and the delay line can be miniaturized.

Title: Production of 2,6-dialkylnaphthalene
Inventor: OTAKE MASAYUKI
IPC: B01J20/18
Filed: 1990-09-03
Abstract: PURPOSE:To produce the subject compound by separating the 2,6-isomer from a feedstock oil containing a dialkylnaphthalene isomer mixture, subjecting the residual feedstock oil to converting reaction, raising the concentration of the 2,6-isomer, removing part, etc., of the 1,8-isomer fraction from the resultant reaction product and recycling the obtained dialkyl derivative to the initial step. CONSTITUTION:A feedstock oil containing a dialkylnaphthalene isomer mixture is brought into contact with Y-type zeolite preferably subjected to ion exchange with La, Ba, etc., to separate and obtain the 2,6-isomer. The resultant feedstock oil at a reduced 1,6-isomer concentration is then subjected to converting reaction in the presence of a solid acid catalyst or a Lewis acid catalyst in the vapor or the liquid phase at 20-500 deg.C under atmospheric pressure to 50 atm to raise the 2,6-isomer concentration. The obtained reaction product is subsequently fed to a distillation column to distill away low-boiling substances from the column top. Bottom liquids are then distilled to distill away the 1,8-isomer together with highboiling substances from the column bottom to the outside of the system. A dialkyl derivative obtained from the column top is then recycled to the initial step. As a result, operation can be smoothly performed by removing the 1,8-isomer.

Title: Thrust bearing device
Inventor: ANDO MASATOSHI
IPC: F16C33/10
Filed: 1986-10-02
Abstract: PURPOSE:To increase the ratio of pressure receiving area of a pad to a thrust runner so as to restrict cavitation by annularly arranging plural fan-shaped thrust pads, which support the thrust runner, through narrow spaces, and opening an oil filler hole to the end portion of the pad on the rotational direction side. CONSTITUTION:In the case that there appears the symptom of any cavitation due to negative pressure on the end portion of a pad 1 on the rotational direction side, pressure oil is supplied from an oil filler hole 3 opening to said portion. And, oil film pressure is kept higher than the atmospheric pressure so as to prevent the phenomenon of absorbing bubbles in surroundings. In addition, respective pads 1 are mutually adjacent to each other through a narrow space (g), so that the bubble amount staying in a space between pads 1 can be remarkably restricted in comparison with devices having the conventional constitution. Moreover, although the space (g) is narrow, temperature-up oil and cold oil supplied from the oil filler hole 3 are mixingly heat-exchanged in a sliding portion, hence rendering it possible to maintain the lubricating function.
