IPC: G02B13/18
Filed: 1990-02-22
Abstract: PURPOSE:To obtain the compact high-variable-power zoom lens which is short in overall length although the lens has an about X2.5 - X3 variable power rate by composing the zoom lens of four lens groups, moving at least the 1st, 3rd, and 4th lens groups on the optical axis to the object side, and satisfying specific conditions. CONSTITUTION:The zoom lens consists of the 1st positive lens group, the 2nd negative lens group, the 3rd positive lens group, and the 4th negative lens group and at least the 1st, 3rd, and 4th lens groups move on the optical axis to the object side for variable power from short focus to long focus to satisfy an expression I. In the expression, Miw and Mit (i=2, 3) are long-focus and short- focus power values of an (i)th lens group. Further, the zoom lens is focused preferably by the 2nd lens group and the power is varied by moving the 1st and 3rd lens groups in one body. Consequently, a wide angle is included and the high power variation ratio of up to about X3 is obtained; and the telephoto ratio is nearly 1 even on the telephoto side and aberrations are compensated by the compact constitution with good balance over the entire power variation range.

Title: Address recording system of flexible disc
Inventor: TAKUBO AKIO
IPC: G11B21/10
Filed: 1978-04-05
Abstract: PURPOSE: To lower the decrease in throughput by recording the position of the first sector of the next track behind the final sector of an arbitrary track, with a delay of  more than the rotating angle corresponding to the time required for moving and  settling of a magnetic head for 1 track.  
     CONSTITUTION: At the time of detecting the index signals from a disc apparatus and recording address information for 1 track in a disc 4, the address information is so configured that the origin sector S 0  of the sector address of each track is deviated in the direction opposite from the rotating direction of the disc in compliance with the ascending direction of the track addresses. Hence, at the time of performing read-write operations after moving the magnetic head 1 to the next track then allowing the same to settle upon finishing of reading and writing of the final sector Sn, there is virtually no need for rotation latency time of the disc and therefore throughput may be incresed.

Title: Key switch of small-sized electric apparatus
Inventor: YOKOTA REI
IPC: H01H3/12
Filed: 1988-02-23
Abstract: PURPOSE:To prevent misoperation in key entry by forming the keys in such an arrangement that they have smaller tallness with approaching the front of the electric apparatus concerned, furnishing a boss on the panel adjoining to each key top, and thereby allowing any key top to be pushed solely with certain performance. CONSTITUTION:The key tops 4, 5 are made with smaller tallness with approaching the front of the electric apparatus, and a boss 9 with appropriate tallness is provided on the outer side-face of the panel 10 penetrated by the key tops 3-5 in such a position as adjoining to each key top 3-5 in order the push-in strength to be equal at the time of operation. Accordingly eventual pushing of two tops 4, 5 by one finger does not cause the conductive rubber corresponding to the lower one 5 to reach the printed circuit board 8, and entry through the upper one 4 is solely achieved certainly. The key with longer key top is prevented from excessive depression by means of the boss 9 provided on the panel 10. Thus only one intended key is pushed certainly to eliminate risk of mishandling in entering the settings, etc.

Title: Tape cassette
Inventor: KOMIYAMA KOZO
IPC: G11B23/087
Filed: 1990-02-20
Abstract: PURPOSE:To prevent a tape reel form being given unstable pressing force by providing a reel pressing spring for giving its pressing force in an axial direction of the tape reel integrally with the tape reel. CONSTITUTION:The tape reel 2 is pressed in the direction of its rotational axis by the reel pressing spring 11 provided integrally with it, and the reel pressing spring 11 becomes a contact rotation part, so that vibration in the vertical direction is prevented. That is, since the reel pressing spring 11 for giving its pressing force to the tape reel 2 is provided integrally with the tape reel 2, the constant pressing force can always be given to the tape reel 2 in the axial direction. By this method, the vibration in the vertical direction of the tape reel 2 can effectively be prevented without giving unstable force to the tape reel 2 in its rotation, and hence the stable rotation of the tape reel 2 can be obtained.

Title: Wide band signal switch matrix circuit
Inventor: KATAOKA HIDEKI
IPC: H03K17/62
Filed: 1982-03-16
Abstract: PURPOSE:To obtain a switch matrix which outputs no excessive DC voltage without using a dummy switch, by adding a simple circuit using a field effect transistor, in a wide band signal switch matrix circuit. CONSTITUTION:When a switch 9 or a switch 10 is in a conducting state, a transistor (TR) 16 is set to a conducting state by a control terminal 6, so that a current is supplied to the switch 9 or 10 through a resistance 8. In this case, a voltage drop by the resistance 8 is applied as reverse bias voltage, between the gate and the source of a field effect TR (FET) 17 through a resistance 18, and the drain-source voltage attains to a cut-off state. When cutting off both switches 9, 10 it is unnecessary to supply a current to the output side of the switch, therefore, the TR16 is turned off by the voltage of the control terminal 6. In this case, no current flows to the resistance 8, the gate-source voltage of the FET 17 reduced to zero volt, and the drain-source voltage attains to a conducting state. A signal which leaks from the switch 9 or 10 is scarcely outputted to an output terminal 7.

Abstract: PURPOSE:To quickly remove a mushroom (mass body) for effectively operating a converter by a method in which the mushroom formed at the top of a nozzle is forcibly cooled after the blowing operation in a converter refining method in which a gas is blown into the converter through a nozzle provided below a bath. CONSTITUTION:After the completion of converter refining, or the finishing of slag removal, a coolant 15, e.g., water, a gas, etc., is blown onto the mushroom 2 formed in the converter body 9 tilted so as to forcibly cool the high-temperature mushroom 2.

Thus, the mushroom can be made into an easily separable state. Then, the mushroom 2 is scraped down by a scraping bar 12 attached to a self-running, cooling scraper 11, or wiped down by a jet lance 13.

Filed: 1989-02-20
Abstract: PURPOSE:To obtain a parallel guided light without using a wave guide type lens element and to reduce the insertion loss of a whole device by so composing as to guide a parallel beam output from a surface emission type semiconductor laser to an optical waveguide. CONSTITUTION:Only a light having a wavelength determined by the period of a diffraction grating is selectively amplified while a light generated in an active layer 4 in a current injection part 11 of a semiconductor laser 20 is propagated into the part 11 to generate a laser oscillation. The generated laser light is propagated into a current noninjection part 12 but since the second order diffraction grating is used in an optical guide layer 6, part of the propagated light is output perpendicularly to an advancing direction as the first order diffracting light at the part 12. Since the layer 4 has a quantum well structure, the propagated light is invaded into the deep side in the part 12, the first order diffracting light emitting range is increased in width, thereby outputting a light parallel to a laser oscillator direction. Since the upper clad layer 7 of the part 12 is end-coupled to an optical waveguide 13, the light emitted from the grating is guided to the waveguide 13 to obtain a parallel guided light.
