Abstract: PURPOSE:To improve a detection S/N without executing the narrow band of a BPF, in a tracking error detector which detects a tracking error by comparing the output levels of reproducing pilots. CONSTITUTION:Two signals whose frequencies are the same with the frequency of the pilot, and whose phases are different from the phase of the pilot by 90 degrees, are generated by a frequency-dividing means 6, a regenerative signal and the signals are respectively multiplied by multiplying means 8 and 9, useless components are removed by two LPF 12 and 13. Then, the two outputs from the two LPF 12 and 13, and the outputs of inverting means 16 and 17, are synthesized into one waveform by a four signal switch means 21. The detection of an envelope is operated by an error detecting means 23 by using the output of the four signal switch means 21, the tracking error is detected regardless of the reproduced phase of the reproducing pilot, and the narrow band of the LPF 12 and 13 is executed, so that the detection S/N can be improved.

Title: Mig arc welding method
Inventor: KOSHIYOU MASAAKI
IPC: B23K9/16
Filed: 1984-09-13
Abstract: PURPOSE:To obtain a weld zone having no defect and having excellent mechanical qualities and good welding workability by a weld metal of low oxygen, by using a shield gas as a mixed gas of argon and helium, and also limiting the content of helium gas, when executing MIG are welding in a pure inert gas by adding a rare earth element to a welding wire or a base metal. CONSTITUTION:Other inert gas is unsuitable as a welding shield gas, and in case when argon gas and helium gas have been used singly, they are not suitable due to a deterioration in stability of an arc and an increase of oxygen quantity in a weld metal, therefore, a mixed gas is used as a shied gas. Also, the helium gas content in the shield gas is limited to 5-80vol%. In case of <=5vol%, lack of fusion is generated in the end part due to front bead, and in case of exceeding 80vol%, an arc becomes unstable. In this way, a MIG arc welding is executed in said pure inert gas shield by adding a rare earth element of 0.02-0.3wt% to one or both of a welding wire and a base metal.

IPC: G03B17/52
Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To provide an instant camera incorporated with a stroboscope device, without increasing the size of a camera. SOLUTION: A driving motor 34 for rotating extension rollers 25a and 25b and a main capacitor 35 storing an electric charge for allowing a discharge tube 31 to emit light are placed side by side at the front and the rear and held between a light shielding barrel 26 and a front cover 22, under the light shielding barrel 26 for shielding the light from a photographic lens 27 to the exposed surface of a film unit 20. The driving motor 34 is arranged so that its outer periphery is in contact with both of a plane F level with the bottom surface of a main body part, 21 and the external wall of the light shielding barrel 26. Then, the main capacitor 35 is arranged in a gap necessarily formed on the back side of the driving motor 34.  Since it is unnecessary that space for storing the main capacitor 35 is particularly provided in the instant camera 10, the increase of the size of the camera can be suppressed.

Title: Linear motor
Inventor: INOUE HIROTO
IPC: H02K41/03
Filed: 1987-07-30
Abstract: PURPOSE:To generate high-powered thrust, by forming fixed pole teeth and mobile pole teeth of superconductive members. CONSTITUTION:In a linear stepping motor, superconductive teeth 10 on fixed pole side made of numerous film materials with a constant pitch p1 in the longitudinal direction having width d1 and thickness t1 on the surface of a moving piece 2 side of a stator yoke 3. On the surface of the above stator 1 side of the yoke 3, superconductive teeth 11a-11d on the mobile pole side made of the same superconductive film material are formed in four blocks. The phase of each tooth is deviated at 90 deg. each. Since these superconductive teeth 10 and 11 are made of superconductive materials, the invasion of flux into the superconductive teeth 10 and 11 is blocked because of Meissner effect, the proper effect of a super conductive material. The superconductive teeth 10 and 11 fulfill the same function as in the pole teeth composed of a conventional uneven magnetic material. As a result, the motor can perform stepping with high precision and high-powered thrust can thereby be generated.

IPC: G06F3/12
Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To improve the printing capable of an entire network by selecting a proper printer corresponding to printing data in a distributed print network environment. SOLUTION: An average data amount per page is calculated by respective data classes of text data, graphic data and image data in print-out data (106), that average data amount for each data class is divided with the printing capability of each printer for each data class and by summing up that divided result for each data class, a printing processing load index for each printer is calculated (108). Since this printing processing load index shows the level of load of printing processing corresponding to the printing capability of each printer, the printers of which the printing processing load index is less than a reference value '1' are selected (110). In the selected printers, the printer of which the printing processing load index is maximum (namely, the printing capability is minimum) is selected (112).

Abstract: PURPOSE: To reduce friction, and to prevent the occurrence of impact sound by providing an interlocking means for guiding ratchet claws so that only the ratchet claws within the driving region at the time of eccentricity of an eccentrically moving body are engaged with an output side rotating member. CONSTITUTION: An interlocking pin 25 is engaged with a guide groove 26 as the ratchet claws 19 within the driving region D are tilted to turn an interlocking member 23, so that all the ratchet claws 19 are interlocked to each other for keeping the same inclination. Therefore, at the time of speed change, only the ratchet claws 19 within a driving region D out of the entire ratchet claws 19 engage with the ratchet gear, and the other ratchet claws 19 are rotated in the state they are disconnected from the ratchet gear. Accordingly, the occurrence of friction and impact sound as before caused by frictional movement while the ratchet claws 19 outside the driving region D are moved in contact with a ratchet gear can be prevented as much as possible.

Abstract: PROBLEM TO BE SOLVED: To avoid the friction due to the relative displacement between a heater and support block at heating and cooling and improve the support accuracy and heating efficiency of the heater by supporting the heating body with spherical rolls rotatably disposed in at least three radically cut V-grooves. SOLUTION: Required number of V-grooves 16 are radially cut into the bottom face of a chamber body 2 with equal spacings along a smaller concentric circle than the peripheral circle of a wafer holder 5, spherical rolls 18 are mounted in the V-grooves 16 one to one to support the periphery of a heater 6, the rotation of the rolls 18 in the V-groove is limited to only radial directions to restrain the motion and they never shift when the heater 6 is mounted, but the rolls 18 can roll freely in the radial directions to follow up the expansion/ shrinkage of the heater 6 at heating/cooling, hence no sliding friction occurs between rolls 18 and heater 6 and the heat conduction quantity to the rolls 18 reduces because of the point contact.
