Title: Tool head replacing type machine tool
Inventor: OOKUBO TAKESHI
IPC: B23Q3/157
Filed: 1984-03-23
Abstract: PURPOSE:To aim at increasing the number of stocks without increasing the installation area of a machine tool, by laying a second stock rail in parallel with and above a first stock rail on the front surface of the upper section of a machine frame so that a tool head may be moved left and right and as well may be reversibly moved toward both outsides of both rails. CONSTITUTION:When an elevating base 6 is moved upward, pawls 13c, 13d engage with machining heads 4 on an elevating rail 7 and a reversing rail 16, repsectively, and the heads 4 are released from its secured condition against a coupling 9c and the elevating rail 7 into its unclamped condition. When a shift frame 13a is shifted, the head 4 on the elevating rail 7 is moved thereon, and then is positioned and secured on the base 6 by means of a cylinder 10 so that a tool drive shaft 4a is set in preparation for machining of a workpiece (a). Then the pawl 13c is rotated to its releasing side while the pawl 13d is rotated toward its engaging side when the base 6 is moved downward, so that the pawl 13d is engaged with two heads 4 on a second stock rail, and therefore, the heads 4 are shifted onto rails 16, 14, respectively in accordance with a shift of the shift frame 13a, thereby the heads may be reversed by means of rotary frames 15 on both sides.

Title: Pseudo fault generator
Inventor: KIYOO KATSUHIKO
IPC: G06F11/22
Filed: 1980-04-24
Abstract: PURPOSE:To vary the timing of fault detection freely by generating a specific fault artificially when an assigned address for reading a micro (mu) instruction reaches preset one. CONSTITUTION:The address of a (mu) instruction generating a pseudo fault is inputted to assigned-address register TAR3 by program PG, and a code expressing the kind of the fault to be generated is also inputted to register DFR11 which indicates in which part of a data processor a pseudo fault should be generated. The address is increased by one address with control storage 1 to read and execute (mu) instructions and when the coincidence between the contents of control storage address  register CAR2 and those of TAR3 is found by address coincidence circuit 4, the  output signal of circuit 4 sets FF8 via gates 5 and 7 to make decoder 12 effective.  The code of DFR11 is decoded by decoder 12 and with this signal, the prescribed pseudo fault is generated. According to contents of TAR3 and DFR11, the pseudo  fault is generated at optional timing.

Title: Optical fiber module
Inventor: MURASHIMA KIYOTAKA
IPC: G02B6/10
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To prevent the reflection wavelength of a diffraction grating from being changed by a temperature change when mounting an optical fiber with the diffraction grating to a fixing member, such as a substrate. SOLUTION: A portion of the optical fiber 1 including the diffraction grating 2 of the optical fiber 3 with the diffraction grating formed with the diffraction grating 2 in part in the longitudinal direction of the optical fiber 1 is fixed along a holding member 4 consisting of a material having a negative coefficient of thermal expansion, by which the temperature compensation of the optical fiber with the diffraction grating is effected and the holding member 4 is fixed to the fixing member 6, such as the substrate. As a result, the thermal expansion and the change in the refractive index accompanying the temperature change of the optical fiber 3 with the diffraction grating are compensated by the fixation of the holding member 4 having the negative coefficient of thermal expansion and the occurrence of a deviation in the reflection wavelength is averted.

Title: Phase shifter
Inventor: TOYODA YUKIHIRO
IPC: H01P1/18
Filed: 1989-03-09
Abstract: PURPOSE:To simplify the constitution and to suppress the increase in the insertion loss by varying a phase of a passing signal from an input terminal of a 1st circuit up to an output terminal of a 3rd circuit in a range of at maximum of 360 deg. based on the control of the level attenuation of a 2nd circuit. CONSTITUTION:Only a variable attenuator 22 for a 120 deg. vector is controlled, a variable attenuator 21 for a 0 deg. vector is brought into a through-state and the output of a variable attenuator 23 is made zero. In this case, the phase of an output signal SOUT is varied in a range from 0 deg. to 120 deg.. When the variable attenuator 22 for a 120 deg. vector is brought into a through-state, the amplitude of the output signal SOUT represents its maximum value similar to the case when only the variable attenuator 21 for a 0 deg. vector is brought into a through- state. Conversely when the output of the variable attenuator 22 for a 120 deg. vector is halved to the maximum value, the amplitude of the output signal SOUT represents its minimum value. When the amplitude of the output signal SOUT represents its maximum value, a power being a multiple of 1/3 of input power is finally outputted, and when the amplitude of the output signal SOUT represents its minimum value, a power of a multiple of 3<1/2>/6 of the input power is outputted, then the insertion loss of each phase shifter is small.

Filed: 1986-03-14
Abstract: PURPOSE:To improve the process control performance at circuit integration by using a depletion mode MESFET as a load and a JFET of enhancement mode as a drive element so as to ensure a large logic amplitude. CONSTITUTION:A JFET 2 of enhancement mode and MOSFET 1 of depletion mode are connected in series. Then an input signal VIN is fed to the JFET 2 to obtain an output signal Vout from a connecting point between the MOSFET 1 and the JFET 2. A high gate barrier due to the p-n junction between the gate and channel of the JFET 2 used as the drive element, resulting that a large logic amplitude is obtained. In the MOSFET 1 used as a load, the control of density and thickness at processing is not required by the design without the provision of a gate region like a JFET between the gate electrode and the channel region.

Title: Production of acetyl compound
Inventor: FUJIWA TAKAAKI
IPC: C07C51/56
Filed: 1984-03-22
Abstract: PURPOSE:To produce the titled compound preventing the lowering of the activity and selectivity of the reaction and using the catalyst liquid repeatedly, by separating the volatile component from the reaction liquid produced by the carbonylation reaction of an O-methyl compound using Rh as a main catalyst, and treating the obtained catalyst with hydrogen. CONSTITUTION:An O-acetyl compound (e.g. acetic anhydride) is produced by the carbonylation of an O-methyl compound (e.g. methyl acetate) with carbon monoxide in the presence of an Rh catalyst and an iodine compound (preferably methyl iodide). The liquid produced by the carbonylation reaction is subjected to the flash distillation to separate the volatile component from the catalyst liquid containing Rh. The separated catalyst liquid is heated at 100-200 deg.C in the presence of a hydrogen-containing gas having a partial hydrogen pressure of >=0.2kg/cm<2> to reactivate the catalytic activity which is lowered remarkably by the flash distillation, and the activated catalyst liquid is reused. When the above hydrogen treatment is carried out in the presence of CO having a partial pressure of >=0.1kg/cm<2>, the production of methane can be suppressed, and the recovery of the catalytic activity can be promoted.

Abstract: PURPOSE:To contrive the generator to be made small-size and the improvement of a power performance per weight by a method wherein a space between side faces of magnetic poles in adjacent different polarities is expanded wider nearer the center of a rotor. CONSTITUTION:An axial length B' of a magnetic field winding wound part of the rotor 1 is taken almost equivalent to a stator core lamination thickness and shortened as compared with the conventional length. The length of the space between the both side surfaces 20', 21' in which adjacent heteropoles of pawl-shaped magnetic pole parts of the magnetic poles 1a, 1b which are arranged so as to be alternately differently polarized along the outer peripheral surface of the rotor 1 are faced to each other, is gradually increased in approaching nearer the center of the rotor 1 as compared with a length E' of a space formed along the outer diameter R1 of the magnetic pole, and a length F' of a space along the inner diameter R2 of the pole becomes the largest. An opening angle theta showing the expansion between the both side surfaces 20', 21' represents the angle which is opened toward the center of the rotor 1 at the section vertical to a rotor shaft 5. Thereby, the generator weight is reduced and the power per weight can remarkably be improved.
