Title: Cassette housing
Inventor: HARIMA MASAHIRO
IPC: G11B15/675
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent a magnetic tape from being hung when taking out a tape cassette by forming a cassette slider stopper, which is fixedly arranged on a cassette housing and abutted to the cassette slider of the tape cassette to be inserted, so as to be obliquely extended from the downside to the back in the inserting direction of the tape cassette.

Abstract: PURPOSE: To obtain the reactor requiring no reconstruction of dust, formation of notched portion, etc., by slantly arranging the catalyst layer inside a vertical type duct at which an upper duct and a lower dust are in contact with each other without forming waste gas traps inside the duct.  
     CONSTITUTION: The catalyst layer 2a is slantly probided inside the vertical type duct 10 connecting the uppr duct 1 with the lower duct 3 in such a way that the catalyst layer 2a can gradually reduce the sectional area of the duct 1 and also can gradually increase the sectional area of the duct 3. In the reactor, waste gas G in the duct 1 is sent to the catalyst layer 2a and introduced into the layer 2a by an upper rectifying plate 4a for accelerating reactions, and then the waste the gas G coming out of the catalyst layer 2a is directed into the lower duct 3 by a lower rectifying plate 5a, where on deposition of dust occurs on the right-hand end portion of the duct 3, or the dust-trapping area usually. Thus, the lowering of flow rate of the waste gas can be prevented without needs to install partition plate, porous plate, etc., and therefore the deposition of dust can be greatly lessened.

Filed: 1988-04-21
Abstract: PURPOSE:To make a magnetic head capable of following the curving of a card by making a magnetic head rockable in the direction perpendicular to the card- running direction together with a supporting plate. CONSTITUTION:In the small hole 3a and the notch 3b of a plate spring 3, pins 5, 6 are respectively inserted through, and the pins 5, 6 are planted in the supporting plate 7, the parts of the pins 5, 6 abutting the plate spring 3 are tapered so that the spring 3 can freely rock. The supporting plate 7 is fastened on a magnetic card reader main body 8 with screws 7a-7d. The magnetic head 1 penetrates the opening 7e of the supporting plate and that 8a of the magnetic card reader main body 8, protrudes the foremost end of its own into a card passage 9. The plate spring 3 can displace up and down following the curvature of a magnetic card 4 inserted into the above mechanism, however, since the spring is supported at its tapered part by the pins 5, 6, it can freely rock. As a result, the magnetic head 1 can rock up and down freely following the curvature of the card in its width-direction.

Abstract: PURPOSE:To prevent the lowering of output characteristic of the apparatus caused by an attempt to reduce the size thereof by arranging first and second ceramic resonators on a ground surface of a circuit board and ground electrodes opposed to each other near an output terminal of the second ceramic resonator. CONSTITUTION:First and second ceramic resonators 6 and 7 are arranged on a ground surface of a circuit board 10 and ground electrodes 16 are arranged opposing to each other near an output terminal of the resonator 7. Then, as a ground conductor plate 14 is provided connected in continuity to a ground opposed surface of the resonator 7, Q of the resonator 7 becomes higher to compensate for a drop in Q caused with a smaller size of resonator 7. An extension of the conductor plate 14 is opposed near the output terminal of the resonator 7 as electrode 16 or another independent ground electrode is disposed near the output terminal of the resonator 7. This can prevent the lowering of a voltage level of a carrier thereby compensating for a drop portion of a voltage level caused by an attempt to reduce the size of the resonator 7.

Title: Counting display circuit for signal peak-value segment
Inventor: ENDOU NORIO
IPC: G01R19/04
Filed: 1978-08-11
Abstract: PURPOSE: To count and display accurately the total number of peak values of each segment by counting up either one of outputs of adjacent analog comparator circuits while counting down the other.  
     CONSTITUTION: Up/down UD counter 61 counts up in a fall of the output of comparator circuit 21 at time (t 1 ), but counts down to its original count value when the output of comparator circuit 22 rises at time (t 2 ) and arrives at down (d) input.  Therefore, the contents of display unit 81 displaying the contents of the counter  at any time vary as long as a time difference between (t 1 ) and (t 2 ), but it is short  enough not to notice, so that an observer will accept them as the display contents  before time (t 1 ). Similarly, momentary variation in display content between time  (t 2 ) and (t 3 ) can not be confirmed as to UD counter 62. However, since UD counter 63 is applied with an up (u) input at time (t 3 ) and not with a (d) input, it  counts up by one, so that the contents of display unit 83 will increase by one.  consequently, the total number of each segment can accurately be counted and  displayed.

Title: Method for melting molten steel for nonoriented silicon steel sheet low in core loss
Inventor: TAKASHIMA MINORU
IPC: C21C7/06
Filed: 1994-05-11
Abstract: PURPOSE:To melt molten steel for a nonoriented silicon steel sheet low in core loss, at the time of melting molten steel having a specified componental compsn., by reducing the concn. of dissolved oxygen under specified conditions before the regulation of Si components by refining outside of the furnace. CONSTITUTION:Molten steel for a nonoriented silicon steel sheet having a compsn. contg., by weight, 0.01% C, 0.05 to 1.0%, Si, 0.05 to 0.5% Mn, <=3% P, <=0.0010% sol.Al, and the balance Fe with inevitable impurities is melted. At this time, prior to the componental regulation of Si in refining outside of the furnace, vacuum degassing treatment is executed to reduce the concn. of dessolved oxygen in the molten steel to <=700wt.ppm, and furthermore, by deoxidation with Al, the concn. of dessolved oxygen in the molten steel is regulated to 50 to 200wt.ppm. Next, by using an Fe-Si alloy in which the content of Al is limited to <=0.3%, the componental regulation of Si is executed by refining outside of the furnace. Thus, the low Si nonoriented silicon steel sheet low in core loss can be produced under good operability and economization.

Title: Scanning type electron microscope
Inventor: TOMIZAWA JUNICHIRO
IPC: H01J37/244
Filed: 1987-04-22
Abstract: PURPOSE:To obtain the sufficient signal even if the operating distance is increased by arranging a secondary electron detector above an upper magnetic pole and a reflection electron detector on the sample side and synthesizing respective signals. CONSTITUTION:A reflection electron detector 5 is arranged on the sample 3 side of an objective lens upper magnetic pole 2, and its signal is synthesized with the signal of a secondary electron detector 4 arranged above an upper magnetic pole 2. Secondary electrons from a sample with a large operating distance are hard to pass the hole of the upper magnetic pole 2 by the effect of an objective lens magnetic field, but when the reflection electron detector 5 is arranged on the sample 3 side of the upper magnetic field 2, the secondary electron signal is supplemented by the reflection electron signal. A good image with a low magnifying factor can be observed by a high-resolution objective lens.
