Title: Heat-treating furnace for spring
Inventor: MATSUI KAZUROU
IPC: C21D9/02
Filed: 1983-02-14
Abstract: PURPOSE:To provide a heat-treating furnace which enables sure execution of a uniform heat treatment for various formed springs by fitting a freely liftable furnace cover body to a furnace body provided with heaters and a product- containing rack, and providing a product inlet and outlet alongside the fitting part. CONSTITUTION:Spring products (a) right after forming are put in a case 14, pushed from a table base 13 through an inlet and outlet 5 into a furnace body 2 and are set on a product-containing rack 4. A furnace cover body 3 is lowered to fit and close hermetically both bodies 2, 3, thereby shutting off the outdoor air. The temp. in the body 2 is increased by heaters 1, 1' and a fan 10 is run to heat-treat the products (a). A sensor 12 is pressed to the products (a) upon fitting of the body 3 and the measured value detected therewith is displayed on a control panel 15, whereby the heat-treating temp. is adequately controlled. When the heat treatment is finished, the body 3 is moved upward and the body 2 is opened. The case 14 is then drawn out through the inlet and outlet 5 onto the base 13.

Title: Waste gas purification device of roaster
Inventor: TAKANO YASUSHI
IPC: B01D45/12
Filed: 1998-01-20
Abstract: PROBLEM TO BE SOLVED: To lessen maintenance work by providing a sepn. chamber into which waste gases flow with inlet and outlet flow passages for the waste gases varying in flow passage directions, setting intricate flow forms, separating mists by inertia force and capturing the mists in the oil smoke absorbent material in the sepn. chamber. SOLUTION: The waste gases are passed to an outer side along the rear surface of a rear surface plate 43 by the suction effect of a smoke suction cylindrical section 35 of a smoke collecting cylinder and are sucked into the inner side of a smoke collecting hood 36. The waste gases are sucked as ascending streams from a flow passage spacing 44 between this hood and the rear surface plate 43 into the smoke suction cylindrical section 35. The waste gases are made into rotating streams and are directed toward the center by flow regulating fins 41, 41a... and while the waste gases are risen, the gases are rotated and are directed as downward swirling streams toward the smoke suction cylindrical section 35. The gases are sucked to a U turn form by drawing the descending streams and ascending streams near the bottom end of the smoke suction cylindrical section 35.  The waste gases are made into the descending streams just before the smoke suction cylindrical section 35 and are brought into collision against the oil smoke absorbent material S of the rear surface plate 43. The mists, etc., included in the waste gases are separated by interior force and are directly adhered to the respective members of the device 40, such as the flow regulating fins 41, 41a... or are directly captured in the oil smoke absorbent material S. The degradation in the purification capability of the device 40 is averted and the continuous operation is made possible.

Title: Character recognizing device
Inventor: SANO NAOKI
IPC: G06K9/46
Filed: 1990-02-02
Abstract: PURPOSE:To attain the stable extraction of strokes and to improve the character recognizing rate by changing the parameter for extraction of strokes and repeating a similar operation if the characters are unrecognizable. CONSTITUTION:A character signal In is read by a photoelectric transducing part 1 and stored in a picture memory as an original pattern after the binary conversion. A stroke extracting part 3 tracks the contour of the original pattern and applies the approximation of a broken line to a detected contour point series for extraction of the strokes of the original pattern. A feature value extracting part 4 extracts the feature value including the stroke length, position, etc. An identification part 5 collates this extracted feature value with that of a sign character contained in a dictionary and recognizes the characters. Then a control part 6 changes each parameter used for approximation of a broken line as long as the recognition result given from the part 5 is unrecognizable. Then the part 6 carries out again the operations following the extraction of strokes to newly extract the strokes. Then the recognition of characters is tried again. Thus it is possible to stably extract the strokes and to improve the character recognizing rate.

Title: Communication equipment
Inventor: KONISHI TAISUKE
IPC: H04L27/22
Filed: 1995-02-13
Abstract: PURPOSE: To obtain a communication equipment having a stable symbol clock of a π/4 shift QPSK modulation system adopting synchronization detection independently of information data. CONSTITUTION: A synchronization detection circuit 11 outputs in-phase and orthogonal component baseband signals I(t), Q(t). When a level difference detection section applies arithmetic operation of X(t)=|I(t)|-|Q(t)| to the output signals, the signal repeats levels 1, 0 alternately by an optimum clock signal according to the property of the π/4 shift QPSK modulation system. Furthermore, when a delay difference circuit 13 differentiates the x(t) at an interval of a symbol and a full wave rectifier circuit 14 applies full wave rectification to the result, the signal is at logical 1 by the optimum clock and indicates a maximum value. Thus, a band pass filter 15 calculates a mean value of blocks and detects a timing when the means value is a maximum to recover the symbol clock stably.

Title: Partial smoothing circuit
Inventor: TANAKA HIDEHIRO
IPC: H02H7/125
Filed: 1994-02-22
Abstract: PURPOSE:To prevent the dangers of the fuming and the firing of a resistor for preventing inrush current at the time of the short circuit fault of a diode by connecting another diode to the diode of a partial smoothing circuit in series. CONSTITUTION:A diode D4 is connected in series with a diode D1. Therefore, even if the diode D1 fails and the short circuit occurs, the discharge current of a capacitor does not flow into a resistor R because of the diode D4. The charging current can be made to flow into capacitor C1 and a capacitor C2 as the intrinsic purpose. Thus, the resistor R is not heated, fuming and firing do not occur and safety is maintained.

Title: Slider
Inventor: MITSUMASA JIROU
IPC: G11B5/60
Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To reduce a crash by making maximum surface roughnesses (Rmax) of bottom surface 4 of stepped-down parts to be provided at peripheral parts of floating rails to be equal to or smaller than the specific % of the depth of the stepped-down parts to enable dust to hardly remain at the stepped-down parts of the peripheral parts of the floating rails. SOLUTION: A slider 1 is constituted of a ceramic material or the like and has floating surfaces 4, 5 at floating rails 2, 3. Stepped-down parts 6, 7 and 10, 11 having a depth M from the floating surfaces 4, 5 are provided at the peripheral parts of the floating rails 2, 3 and maximum surface roughnesses Rmax of bottom surfaces 8, 9 and 12, 13 of the parts 6, 7 and 10, 11 are made to be equal to or smaller than the 10% of the depth M.  Thus, when the slider 1 is made to be floated on a magnetic disk, even when dust being in air flow to be generated on the surface of the magnetic disk is brought into contact with bottom surfaces 8, 9 and 12, 13, it becomes small that the dust is caught by the bottom surfaces 8, 9 and 12, 13 and moreover, even when the dust is caught by the bottom surfaces, it never occurs that the bottom surfaces grow dusty so as to make the slider 1 crash against the disk.
