Title: Tape guide drum unit
Inventor: YOSHII TETSUJI
IPC: G11B15/61
Filed: 1986-06-13
Abstract: PURPOSE:To surely abut a head and a tape in the tape entrance side without increasing load practically by providing a pad abutting on a stepped part of tape entrance side of a tape lead provided in a fixed guide drum and on a tape that runs in this part. CONSTITUTION:A stepped part is provided in the tape entrance side of the tape lead of a fixed guide drum 1, and a pad 11 abutting on a tape that runs in this part. A tape loading guide block 10 moves guided by long holes 13, 14, and winds a tape 8 on a tape guide drum consisting of a rotary head drum 1 and a fixed guide drum 3. In this case, the pad 11 presses the lower part of the tape 8 against the tape guide drum. A part of the pad 11 abuts on the tape lead 9, and thereby movement in the direction of the abutting is controlled, and at the same time, abutting force is also controlled. Further, floating up of the lower edge part of the tape 8 is also prevented.

Title: Apparatus for preparing single crystal
Inventor: WASHITSUKA SHIYOUICHI
IPC: C30B15/26
Filed: 1983-07-29
Abstract: PURPOSE:To obtain single crystal having stable quality by providing a switching means which selects specified control signal for setting pulling speed successively and feeds the selected pulling speed to a pulling speed setting means. CONSTITUTION:The output of a diameter measuring device is operated by for example a microcomputer, and a control signal is transmitted to a control device for number of revolution of a motor. The control by the control device for number of revolution is performed by the process as described hereunder: pulling speed is increased stepwise from an initial value to a second pulling speed at the time when the diameter D at the shoulder part of a grown crystal coincides with the difference between the previously set target value of final diameter Do and a set value of deviation from the value DELTAD. The time when the diameter at the shoulder part attains peak value Dmax is detected, and the pulling speed is decreased stepwise to a third pulling speed value. Thereafter, control of barrel is commenced by adopting the peak value Dmax as the target value for the control Dref, and Dref is corrected by setting a fourth pulling speed which corrects deviation between the final target value Do and Dref by the detection and adjustment to correct the deviation asymptotically to zero.

Title: Color thermal printer
Inventor: MOGI HIDESUKE
IPC: B41J2/32
Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To improve print quality by stabilizing a conveying amount of a recording paper and preventing loosened winding of a roll of the recording paper due to lacking of a back tension caused by variation of a load of the roll of the recording. SOLUTION: A pair of relaying rollers 11 are provided between a paper supplying roller 4 and a pair of conveying roller 13. The speeds of the relaying rollers 11 are lower than those of the paper supplying roller 4 and the conveying rollers 13. When paper is supplied, a back tension is applied between the pair of relaying rollers 11 and the pair of conveying rollers 13, thereby stabilizing a conveying amount of the color thermal recording paper 2. When the printing is executed, a sag of the recording paper is generated between the pair of relaying rollers 11 and the pair of conveying rollers 13, thereby sucking variation of a load of the roll 3 of the recording paper.  A back tension is applied between the paper supplying roller 4 and the relaying rollers 11 so that the color thermal recording paper 2 is wound back to the roll of the recording paper without generating the loosened winding.

Abstract: PURPOSE:To prevent parison from fleeing to the outside of a mold and to prevent an inner side of the parison from becoming thin at the time of pressure pinching, by providing a weir at a pressure pinching part of a divided mold. CONSTITUTION:When molds 11, 12 are made to approach to each other, parts of parison 6 corresponding to pressure pinching parts A, B are crushed, which are pinched deeply by a weir 15 provided especially by crossing the pressure pinching parts. At the time directly before clamping, the tip part 15a of the weir is approached to the pressure pinching part of the other die 12, the parison 6 is turned into a thinly crushed state so as to cut off a part of the parison 6, and the tip part 15a is retreated to a containment chamber 14 while an elastic material is being compressed. In this instance, the parison 6 whose flow to the outside of the mold is interrupted by the weir 15 is extruded into a hollow part 13 through a gap between a protrusion 11b and the other mold 12. As a quantity, therefore, equivalent to thickness to be extruded is supplied to an inner side part of a contact bonding part, even if the thickness is sunk when compressed air is blown into the mold it does not happen that a hollow part is generated on the inner side of the contact bonding part and the thickness becomes equal with that of the other part or more than that.

Title: Optical pickup device
Inventor: MIYAKE TAKAHIRO
IPC: G11B7/1398
Filed: 1990-05-29
Abstract: PURPOSE:To record and reproduce information with a high precision by diffracting the reflected beam, whose sectional intensity distribution is shaped to an elliptic form by an optical system, in the direction parallel with the major axis direction and detecting the light intensity of each diffracted reflectd beam. CONSTITUTION:The reflected beam reflected by an optical disk 70 has the sectional intensity distribution shaped to an elliptic form by the optical system and is thrown to a diffracting element 20. Diffraction gratings 22 and 23 equally divide the reflected beam into two in the direction of the major axis of the elliptic form and diffract divided reflected beams at different angles. Respective diffracted beams form a light spot which has the sectional intensity distribution of half elliptic forms divided in the direction of the major axis on a photodetector 60. An objective lens 52 is controlled based on output signals from a first detection face 61, a second detection face 62, and a third detection face 63 of the photodetector 60. The offset of a focus error signal for the change of the wavelength of the laser beam oscillated from a laser light source 10 is suppressed in this manner. Thus, information is recorded on and reproduced from a recording medium with a high precision.

Abstract: PROBLEM TO BE SOLVED: To regulate a hot water temperature of a sub-heat transfer tube at the time of simultaneously operating main and sub-heat transfer tubes. SOLUTION: The heat source apparatus comprises a combustion unit 15, an integrally constituted main heat transfer tube 16, sub-heat transfer tube 17, a sub-bypass circuit 23 connected to the tube 17, and a sub-temperature suppressing unit 25 for controlling an opening/closing means 24 for opening a passage of the circuit 23 if an output of a sub-temperature detector 20 exceeds a reference value at the time of simultaneously operating main and sub-heat transfer tubes. Since the unit 25 controls the means 24 to open the circuit 23 when an output of the detector 20 exceeds the reference value, a warm water flows to the circuit 23 and the tube 17, and a heat absorbing amount of the tube 17 is reduced.  Then, since a main operation controller 22 reduces a burning amount by an amount for reducing the heat absorbing amount of the tube 17, the heat absorbing amount of the controller 22 is further reduced. As a result, the warm water of the tube 17 can be approached to a required temperature.
