Title: Non power source built in type optically converted current-measuring device
Inventor: KUNIYASU HARUE
IPC: G01R15/18
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a current-measuring device of an insulation type for measuring a current running in a distribution line which uses a photoconverter not requiring an external power source and can secure a higher insulation level than an existing measuring device from the distribution line to be measured. SOLUTION: A current running in a distribution line 6 generates an electromotive force by magnetic induction to a current measurement current transformer 1 and a power source current transformer 2, whereby the current flows. The current generated by the power source current transformer 2 is inputted to a power source device 4, while the current generated by the current measurement current transformer 1 is inputted to a photoconverter 3. The current is converted inside the photoconverter from an electric signal to an optical signal, outputted and transmitted outside through an optical cable 5. The optical signal is detected outside and converted into an electric signal, whereby a value of the current can be measured.

Title: Optical head
Inventor: AIKO HIDEKI
IPC: G11B7/135
Filed: 1990-04-18
Abstract: PURPOSE:To reduce the offset of a tracking error signal due to the shift of an objective lens produced in the tracking direction by a splitting/focusing element and a multi-split photodetector to form a tracking error signal detection means. CONSTITUTION:A light source 1 is provided together with an objective lens 3, a 2-split detection means 5, and a focus/tracking servo application means 6. Then a tracking error signal detection means consists of a splitting/focusing element 8 which splits and focuses the reflected light sent from an information recording medium 4 and a multi-split photodetector 5. Thus the lens 3 moves from a neutral position of a movable range set in the tracking direction. As a result, the offset is reduced and the quality is improved for the tracking error signal which is obtained as an output even if an optical spot moves on the photodetector.

Title: Multihead sewing device
Inventor: SHIMIZU MASAKI
IPC: D05C5/02
Filed: 1998-03-29
Abstract: PROBLEM TO BE SOLVED: To miniaturize a power circuit, to reduce its costs, and to reduce noises during actuation of various mechanisms for achieving functions by reducing driving currents which drive a plurality of electric actuators of the same function provided at a plurality of heads. SOLUTION: Six presser foot solenoids provided at first to sixth heads are classified into a first group consisting of those for the odd-numbered heads, i.e., the first, third, and fifth heads, and a second group consisting of those for the even-numbered heads, i.e., the second, fourth, and sixth heads, and the presser foot solenoids of the same group are driven and controlled at the same operating timing in such a manner that the operating timing of the second group is delayed a very short period of time from that of the first group. Therefore, a power circuit which supplies drive currents to the six presser foot solenoids can be made to have a small power capacity capable of merely driving the three presser foot solenoids of the same group at the same time, so that the power circuit can be miniaturized and cost low.  Also, the noises of a drive mechanism caused by the action of raising the presser foot can be reduced.

Abstract: PURPOSE:To obtain a foil wound transformer which has excellent cooling performance to prevent the extreme rise of the temperature at the top of a coil by providing a projection on the side wall of a cooling duct near the aperture of the cooling duct where an insulating fluid flows out by housing the coil wound with a foil type conductor and an insulating sheet around the cooling duct. CONSTITUTION:Two cylinder type projections 12 are provided in a cooling duct 10 vertically at a definite interval perpendicular to the direction of an insulating oil 8 flow on both sides of a duct spacer 9 which is a side wall abutted to the insulating oil 8 near the upper outlet of the cooling duct 10. That is, the projections 12 provided on the duct spacer disturb the flow 14 of the insulating oil in the cooling duct 10 to a disturbed flow 15 and disturb a temperature boundary layer formed on the surface of a coil abutted to the cooling duct 10. Consequently, the temperature distribution perpendicular to the flow of the insulating oil is made uniform and the temperature slope on the surface of the coil is made extremely great. Accordingly, the thermal flux to the insulating oil flowing in the cooling duct 10 from the top of the coil where Joule's heat is greatly generated can be made great.

IPC: B41J29/38
Filed: 1991-04-08
Abstract: PURPOSE:To omit an useless operation such as transfer of a same picture to the device main body again by selecting re-use or delete of picture information stored in a storage means as required in the case of revising the setting of an initial value of the device main body. CONSTITUTION:Suppose that picture information used for forming an image is already stored in a RAM 47. When the operator depresses an emulation key of an operation panel 66 to make an emulation revise request, the request is transferred to a CPU 741 by an operation panel control circuit 757. The CPU 741 sends a message such as 'Existing picture information is to be deleted?' to a liquid crystal display section on the operation panel 66, in which the message is displayed based on the system control program attended with the request. The operator observes the message and discriminates it and when the existing information is not used again, the operator depresses an eject key to delete the picture information in the RAM 743 via the CPU 741. On the other hand, when the existing information is used again, the emulation of the main body is revised.

Title: Cooling method of hot rolled steel sheet
Inventor: SAITOU YOSHIYUKI
IPC: C21D9/52
Filed: 1983-06-09
Abstract: PURPOSE:To control the cooling of a steel sheet to desired conditions by computing desirable speed and stopping temperature of cooling basing on the difference less than an allowable upper limit between the strength of a steel sheet and its target one at the time of natural cooling and the functions of the speed and stopping temperature of cooling, in case of cooling a hot rolled material by water. CONSTITUTION:A function G consisting of the difference F less than an allowable upper limit of difference between the strength of a steel sheet and its target one, a cooling speed CR, and a stopping temperature TF of cooling, is expressed by an equation I . When F is positioned by coordinate transformation in the equation I , a functional equation G(GR, TF, F) is expressed by an equation II. The values of speed CR and temperature TF which make G(CR, TF) of the equation II minimum, are desirable. Accordingly, a desirable cooled steel-sheet can be always obtained by acquiring the cooling conditions previously.
