Title: Bath unit
Inventor: TANAKA HIROAKI
IPC: F24H1/00
Filed: 1998-01-20
Abstract: PROBLEM TO BE SOLVED: To provide a bath unit in which a mild additional heating mode or a full additional heating mode can be employed selectively and the time required for heating up the bath is prevented from being extended at the time of automatic operation. SOLUTION: The bath unit is provided with an automatic operating function dropping the water level of bath down to a set level and heating up to a set temperature in addition to independent operation, e.g. additional heating operation. It is also provided with a mild additional heating mode for burning a burner while lowering the combustion capacity appropriately as compared with a full additional heating mode for burning the burner with high combustion capacity. In principle, the bath unit is controlled to make a transition automatically to mild additional heating mode when the bath temperature falls within a specified temperature range with respect to a set bath temperature.  When dropping operation is followed by additional heating operation during automatic operation, full additional heating mode is sustained by means of a controller until the bath set temperature is reached regardless of the principle.

Title: Reel for tape
Inventor: IWAHASHI YUJI
IPC: G11B23/087
Filed: 1995-02-13
Abstract: PURPOSE: To remove the possibility of image deterioration by collating an upper flange with a lower flange provided with a cylindrical hub part around which a tape is wound through the hub part and forming the upper end of the hub part as a thick part. CONSTITUTION: This reel for tape 1a is formed by fixing the upper flange 6 through the hub part after forming a reel member 5 having a ring-state rib 10 on the upper end of the outside hub part 3. In such a case, strength difference between the upper end of the outside hub part 3 and the lower end thereof on the lower flange 4 side is smaller than the reel for tape in the conventional example, and the reel becomes endurable for tightening force of the tape. Therefore, the tape itself is not deformed and the unsymmetrical extension of the tape is prevented. Thus, the tape normally abuts on a recording and reproducing head and the possibility of the image deterioration is improved.

Title: Polarizer
Inventor: TANNO MASAYUKI
IPC: G02B5/30
Filed: 1993-02-15
Abstract: PURPOSE:To provide a polarizer which can be easily produced, is reduced in its cost, hardly generates cracks in metallic films and has high reliability on quality. CONSTITUTION:This polarizer 1 is formed by alternately laminating the metallic films 2 and dielectric films 3. The metallic films 2 are formed of platinum, cobalt or nickel. The light shielding efficiency of a TE mode sharply degrades in general when the thickness of the dielectric films 3 increases excessively as compared with the film thickness of the metallic films 2. The light shielding efficiency of the TE mode hardly degrades in spite of a considerable increase in the thickness of the dielectric films 3 if the metallic films 2 are formed of the platinum, cobalt or nickel. The number of laminations is decreased and the generation of the cracks in the metallic films and the dielectric films is substantially prevented.

Title: Recovery method for base metal from desulfurized slag of molten iron
Inventor: KATOUGI TAKESHI
IPC: C21B3/06
Filed: 1979-03-02
Abstract: PURPOSE: To precipitate base metal contained in desulfurized slag of molten iron to the bottom of a slag pot by means of specific gravity, and to separate and recover the base metal easily, by a method wherein the desulfurized slag is poured into the slag pot into which molten converter slag of twice or more is admitted.  
     CONSTITUTION: Molten iron discharged from a blast furnace is desulfurized outside the furnace by means of soda ash. Pig iron base metal of approximate 10% is contained in desulfurized slag formed at that time. Molten converter slag twice or more as much as the desulfurized slag to be treated is beforehand introduced into another slag pot, and the desulfurized slag is poured into the molten slag. Since the converter slag is high in temperature at approximate 300°C and twice or more in quantity as compared to the desulfurized slag, the desulfurized slag is mixed with the converter slag, and a molten condition is held for one hour or more. Thus, the base metal which is contained precipitates at the bottom of the slag pot by means of specific gravity, and is brought to a condition that is collected to a  massive shape. The mixed slag is discharged to an outdoor slag field from the slag  pot, solidified by pouring cold water, and crushed, and base metal lumps are separated by means of a magnet, etc. and recovered.

Title: Communication equipment for train control
Inventor: NAKADA KENJI
IPC: H04B1/707
Filed: 1994-01-27
Abstract: PURPOSE:To obtain a high quality reception signal by performing an inverse diffusion processing for an input signal by using the same PN code as the PN code performing a diffusion processing for a transmission signal and removing the PN code. CONSTITUTION:In the output signal of an amplifier 7, the leaked spread signal alpha.fA.PN1 (alpha is the leakage constant.) from a ground transmission part A1 exists in addition to the transmission signal fB.PN2 spread originally from the top of a train. In an inverse spread circuit 8b, an inverse spread processing is performed for the output signal of the amplifier 7 by a PN code PN1. In this case, because a band elimination filter 8c has a function eliminating a transmission signal fA, the side of the output of the band eliminating filter 8c becomes the signals roughtly shown by fB.PN1.PN2. When an inverse spreading is performed for these signals fB.PN1.PN2 by a PN code PN1 in the inverse spread circuit 8d, the signals becomes fB.PN2. Therefore, the omission signal from the ground transmission part A1 is not included in the signal transmitted from a transmission signal output circuit 8.

Abstract: PROBLEM TO BE SOLVED: To smoothly discharge a chip to the rear of a blade tool, by forming the shape of a gash part into a protruded surface, and connecting the boundary part between a lead rake face and a bottom blade rake face in with R (Roundness). SOLUTION: A lead rake surface 5 is extendedly formed until crossing with a bottom blade 1, and a gash part 21 is formed so as to be a protruded surface to connect the boundary part with the lead rake surface 5 with R (roundness). However, the whole gash part 21 is not needed to be a single R, but changeable from place to place, for instance, some remainder of a recessed surface in nearby the center part, instead of the single R, is allowed. But an outer peripheral part must be a protruded surface, and the tilt of the surface of the gash part 21 can increase effect as increasing the tilt until about 45 degrees.
