Title: Optical pick-up device
Inventor: TAKAHASHI YOSHITAKA
IPC: G11B7/135
Filed: 1988-08-01
Abstract: PURPOSE:To eliminate the change of an oscillating wavelength due to the output fluctuation of a semiconductor laser and to improve the detecting accuracy of a focus error signal by arranging a wavelength plate on an optical path between the semiconductor laser and a beam splitter. CONSTITUTION:As the wavelength plate, a lambda/2 plate 11 is arranged on the optical path between a semiconductor laser 1 and a polarized beam splitter 3 and fitted freely turnably around the optical axis. By rotating the wavelength plate 11 up to a certain definite angle and causing a light emitted from the semiconductor laser 1 to be incident on the wavelength plate 11, the polarizing surface of the incident light can be changed, and a light-emitting intensity can be changed. Thus, since the light quantity of the light irradiating the surface of an optical disk 6 can be freely changed in a condition in which the light- emitting intensity of the semiconductor laser 1 is fixed, the change of the oscillating wavelength due to the output fluctuation of the semiconductor laser is eliminated, and the detection of the focus error signal can be executed with good accuracy.

Title: Thermal transfer printer
Inventor: KOMURO KIYOTO
IPC: B41J2/325
Filed: 1986-08-18
Abstract: PURPOSE:To prevent the shifting of dot due to the zigzag motion of a paper and to prevent creasing of paper, by pressing the both edges of a film peeling roller and a film pressing roller independently. CONSTITUTION:When a film back tension is higher than a predetermined level and a film winding force is smaller than a predetermined value, an ink film at a printing section is carriable because it is adhered to a transfer paper, but an ink film at non-rinting section is not carriable. Consequently, the ink film is shifted between a printing section and a non-printing section so as to cause creasing of the ink film. But when a film peeling roller 3 and a film pressing roller 4 are pressed with a predetermined force, the film and the paper are moved with the same speed so as to cause no creasing. Since the pressing force is applied independently to the both edges of the film pressing roller 4 and a film peeling roller, the center can be adjusted thereby a dot is not shifted.

Title: Introduction and delivery indicating device for cargo receiving bed
Inventor: OKAYAMA YOZO
IPC: B65G1/02
Filed: 1986-08-18
Abstract: PURPOSE:To indicate the delivery of cargo to facilitate delivery works, by providing a means for transmitting a signal when a cargo shifting fork on a travel crane for introduction and delivery is extended, and by providing a receiver on a cargo receiving bed to indicate the delivery of cargo in accordance with the presence of a received signal in the cargo loading condition. CONSTITUTION:When a crane shifts a delivered article onto a cargo receiving bed, a fork 2 is extended, which is detected by a detector 7 so that a signal transmitting means 6 energizes a transmitter 8. Further, a cargo receiving side cargo presence detector 10 detects the delivered article, and a signal from the crane side is received by a receiver 9, both being delivered to a control means 14 while an indicating means 13 indicates the delivery of cargo. Meanwhile, when a fork-lift or the like shifts an introduced article onto the receiving bed, the cargo presence detector 10 detects the introduced article but the transmitter 8 is not energized since the crane fork is not yet extended, and therefore, no signal is received by the receiver 9 so that the indicating means 13 indicates the introduction of cargo. Accordingly, it is possible to clearly distinguish between the introduction and delivery of cargo onto the cargo receiving bed and thereby to facilitate the cargo handling work.

Filed: 1993-07-12
Abstract: PURPOSE:To attach required amount of solder to a required place on a part pattern by constituting conductors on printed patterns in such a manner that a reactance value or resistance value preset by a conductive layer can be obtained. CONSTITUTION:When pattern-printing a coil on one surface of a substrate 2 on which metal layers such as copper were vapor-deposited on both the surfaces, unnecessary metal layer portions on the surface of substrate are removed by etching method by copying a planar (spiral) coil together with a land 4.

Abstract: PROBLEM TO BE SOLVED: To realize the sure supporting of a member to be inserted and prevent the member to be supported of the member to be inserted from exposing outside. SOLUTION: In order to manufacture a push switch, firstly a terminal 26 as an insert member is installed between molds 30 and 31 and the fixed contact 15 on the top surface side of the terminal 26 is abutted against the fixed supporting part 30a of the top mold 30 under the condition that its rear surface side is supported by the head part of a movable supporting member 32. Under the condition as just mentioned above, a resin 12a for forming a housing is poured between the molds 30 and 31, resulting in retracting the movable supporting member 32 from the position indicated with two-dot chain line to that with solid line by means of the pressure of the resin 12a. After the solidification of the resin 12a, the molds 30 and 31 are opened and then the housing is unloaded.  Thus, the rear surface of the fixed contact 15 portion of the terminal 26 is also covered with the resin and no part to be supported of the insert portion is exposed outside.
