Title: Manufacture of longer plastic pipe
Inventor: IWAMOTO AIJI
IPC: B29C48/09
Filed: 1981-10-09
Abstract: PURPOSE:To produce the titled pipe with the replacement of a plug being obviated, by an internal pressure molding method wherein a closing plug is employed with it secured to an extruder at the initial step of the molding, and after adjusting the size of the pipe, the plug is freed to be used as a pipe tip seal. CONSTITUTION:While the floating plug 3 is anchored by a wire rope 2 passed through an air supply pipe 7 extending through the inner part of a die head 1 and secured outside of the extruder, internal pressure is applied by air to mold a pipe 4, and the pipe passed through the plug 3 is cut, and its size is checked. When a state is attained wherein a pipe having a desired size can be obtained constantly, the wire rope 2 is removed or cut from outside, and then the plug 3 becomes free. Then when the pipe 4 is moved forward, since the plug 3 will be brought forward as a tip seal therewith, the plug 3 would not be abraded, so that longer working becomes possible, and a longer plastic pipe can be efficiently obtained.

IPC: G02B6/13
Filed: 1994-07-14
Abstract: PURPOSE:To provide a method for producing an optical waveguide having a small polarization characteristic. CONSTITUTION:This process has (a) a stage for forming a waveguide layer 40 having a core part 32 which is an optical waveguide part and a clad layer 25 which has a refractive index lower than the refractive index of this core part 32 and coats the core part 32 on a substrate 10, (b) a stage for forming a stress control layer 50 consisting of a material having a coefft. of thermal expansion different from the coefft. of thermal expansion of this substrate 10 on the rear surface of the substrate and (c) a stage for heating this stress control layer, then cooling the layer. The internal stress of the direction opposite to the direction of the internal stress of the substrate is generated in the stress control layer in consequence of a difference in the coeffts. of thermal expansion between the stress control layer and the substrate by the heat treatment of the stress control layer. As a result, the strain quantity of the waveguide layer 40 curved by the stage for forming the waveguide layer is decreased and the internal stresses of the core part 32 are decreased and, therefore, the anisotropy of the refractive index by a photoelastic effect is lessened. The optical waveguide having the small polarization characteristic is eventually obtd.

Title: Manufacture of optical master disk
Inventor: MIYAMURA YOSHINORI
IPC: G11B7/26
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To drastically micronize patterns and to increase the density thereof by forming an optical recording film on a photosensitive material, confining the light for exposure to have a intensity below the ordinary diffraction threshold and removing the optical recording film after development processing. SOLUTION: A phase shift plate 3 has such nature in the Y direction that the spot width is as narrow as below a diffraction threshold and conversely wider in the X direction. The master disk 5 is irradiated with a light spot having the Y direction as the guide groove width, by which the patterns are formed on the optical recording film. When a resist is thereafter subjected to development processing, the resist of the parts formed with the patterns of the optical recording film is removed and the rugged patterns are formed. Baking for one hour at 120 deg.C is thereafter executed to change the properties of the resist in such a manner that the resist cannot be chemically removed. The recording film is then removed by an alkaline soln. The patterns are thereby formed with the guide grooves narrower than heretofore.

Title: Both side reproducing mechanism for optical disk reproducing device
Inventor: ITO AKIHIKO
IPC: G11B20/00
Filed: 1987-06-30
Abstract: PURPOSE:To attain the reproduction of both sides without inverting an optical disk by arranging 1st and 2nd optical sensors to both sides of an optical disk, switching the sensor from the 1st optical sensor to the 2nd optical sensor and reading a signal stored in a memory in the opposite sequence from the order of storage in the memory.

Then after the 1st optical sensor 3 is switched into the 2nd optical sensor 4, then the signal stored in the memories 16, 17 in the reverse sequence from the write sequence in the memories 16, 17 is read. Thus, after the optical disk is stopped once on the way of reproduction, then the both sides of the optical disk are reproduced without reversing.

Title: Peripheral controller
Inventor: IIZUKA HIROSHI
IPC: G06F13/00
Filed: 1989-06-26
Abstract: PURPOSE:To prevent the destruction of a program when its rewrite and correction are repeated by comparing an address image with the value of a program counter to produce an interruption signal when the coincidence is obtained from the comparison and at the same time collecting and storing the action information. CONSTITUTION:A comparator 3 always compares the value of a program counter 1 with the value of a dip switch image store register 2. When the coincidence is obtained between both values, an interruption request is supplied to a control circuit 5 of a CPU via an interruption signal line 4. Thus the circuit 5 sets the contents of an interruption vector 6 to the counter 1 via an internal bus 7. Then an execution address of the program stored in a program store area 9 is changed into the head address of the interruption process program designated by the vector 6. Then the information on the actions of a device like the contents of the registers 10 are stored in a storage circuit 8. Thus it is not required to rewrite the program and therefore the program is never destroyed by mistake.

Title: Crack detecting method
Inventor: AKIYAMA NOBUYUKI
IPC: G01N30/88
Filed: 1994-07-15
Abstract: PURPOSE:To simply judge the existence of a crack generated at random on a sample surface regardless of the sample shape or the like by measuring the concentration of a volatile solvent contained in a flowing-out inert gas. CONSTITUTION:A sample 1 whose surface is dried by permeation of a volatile solvent such as acetone into a crack 2, is stationarily placed in a sealed vessel 5. Inert gas such as He, that is, carrier gas 6, is injected from an injection port 7 of the vessel 5. The gas 6 flows along the surface of the sample 1, and flows out of an outflow port 8. In this case, a solvent 4 gasified and deposited from the sample 1 is rolled up in the gas 6, and flows out (8) together with the gas 6, and the concentration of the solvent 4 is measured with a solvent concenntration measuring device10 connected to the rear part of the outflow port 8. That is, the concentration of the solvent 4 containing the gas 6 flowing out of the outflow port 8 is measured with a hydrogen flame ionization detector 9, and outputs a solvent concentration signal 11. Therefore, if the crack 2 exists, the gas 6 contains the solvent 4, and the signal 11 becomes high. If the crack 2 does not exist, the signal 11 is low as it is, and the existence of the crack 2 can be judged from the size of the signal 11.
