Title: Method and apparatus for pressure equalization of hopper for furnace top charger
Inventor: SUGAWARA TAKAFUMI
IPC: C21B7/18
Filed: 1986-03-14
Abstract: PURPOSE:To decrease the amt. of the gaseous N2 to be used and to prevent damage of a stop valve by dust and heat by branching the blast furnace gas generated in a blast furnace in the mid-way of feeding said gas to a cleaner, mixing said gas with the gaseous N2, subjecting the gaseous mixture to dust collection, feeding the gaseous mixture to the inside of a hopper and executing secondary pressure equalization. CONSTITUTION:A branch pipe 11 is branched from the mid-way of a gas pipe 10 for taking the high-pressure gas out of the blast furnace 1 and is connected to the gas cleaner 3 via a flow rate regulating valve 12 interposed in the mid-way of the pipe 11 and an N2 mixer 14 for joining and mixing the gaseous N2 from a gas pipe 13 at the secondary side. After the raw materials are thrown into the pressure equalization and discharge hopper 2, the pressure equalization is executed by a primary pressure equalization device and thereafter, a valve 6 for the primary pressure equalization device is closed and the secondary pressure equalization is started. A gas shut-off valve 16 is opened to introduce the blast furnace gas through the pipe 10 for the above-mentioned purpose. The blast furnace gas and the gaseous N2 are mixed in a mixer 14. The flow rate of the blast furnace gas is decreased to lower the temp. of the gaseous mixture if the temp. of said gaseous mixture is higher than the specified temp. blowing is then executed.

Title: Multiplex processing type frame synchronizing circuit
Inventor: INOUE HARUKO
IPC: H04J3/06
Filed: 1990-03-07
Abstract: PURPOSE:To process a multiplex frame signal with a different synchronization condition such as a bit count number in a frame and a protection stage number by varying a data content of a RAM outputting synchronization discrimination information. CONSTITUTION:A 2nd RAM 2 stores a data from a 2nd buffer 5 by using a 2nd write pulse 2 at the write state of a 2nd write/read signal 107. Then the content of a data read corresponding to an output outputted from a selection circuit 3 and designating an address of a 1st RAM 1 is compared with a multiplex frame signal at a point of time (n) and synchronization state information at point of time of (n-1) based on the condition such as bit count number in a frame and protection number stage. Then the result is outputted as n-point of time synchronization state information 109 representing the synchronization state of synchronization/asynchronization at a point of time (n) after state transition from a (n-1) point of time. Thus, the content of the 1st RAM 1 is replaced with an output of the 2nd RAM 2. Thus, the synchronization condition of a multiplex frame signal is varied to process the discrimination of synchronization/asynchronization.

Title: Video recorder with high quality acoustic recording
Inventor: HANSU YURUGEN KURUTO
IPC: H04N9/83
Filed: 1987-03-13
Abstract: In a video recorder, in which the available frequency range has been extended to about 7.5 MHz by means of circuit means, a frequency- modulated sound carrier (T1u, T2u) is recorded in the upper frequency band (B). During the reproduction, the frequency is converted back to the original frequency (5.5 or 5.74 MHz) by means of a mixed carrier (M) obtained from the line. This frees the frequency-modulated sound carrier of timing errors and additional interfering modulation. Figure 1. <IMAGE>

Title: Burr removing device and method thereof
Inventor: KURITA SADAJI
IPC: B24B9/00
Filed: 1986-03-14
Abstract: PURPOSE:To easily remove burrs produced when an internal tooth spline part is grooved, by a method wherein a peripheral groove, having width wider than that of a groove formed in the internal tooth spline part and depth deeper than that of the groove, is formed in an external tooth spline part engaged with the internal tooth spline part of a work. CONSTITUTION:An external tooth spline part 4 of a burr removing device 1 is first engaged with an internal tooth spline part 102 of work W. Secondly, through rotational driving of the work W, the work W is rotated in a direction B centering around a rotary axis 0. Meanwhile, the burr removing device is vibrated longitudinally in an axial direction, but a brake force F is exerted in the direction of rotation on a spindle. Therefore, when the external tooth spline part 4 is rotated centering around a rotary axis P, it is brought into contact with the internal tooth spline part 102 of the work W, and a press force is exerted on the engagement part. This constitution removes burrs, produced in the groove of the work W, by means of a tip edge 22 and two end edges 62 and 64, which form a cutting edge.

Title: Simple measuring method of acidity for fruit juice
Inventor: IWAMOTO YOSHIKAZU
IPC: G01N33/14
Filed: 1982-04-06
Abstract: PURPOSE:To simply and quickly measure the acidity in high accuracy without being affected by salts in fruit juice or gaseous CO2 in the atmosphere, by diluting the fruit juice to prescribed time as much and measuring its pH and then finding the concentration of the acidity of the fruit juice basing on this pH and preliminarily found correlative expression. CONSTITUTION:Fruit juice is diluted to 50 times as much by pure water and pH is measured by using an electrode for pH measurement. On one hand, the acidity of each solution of the fruit juice is found by a neutralizing titration method and a graph shown by the figure which is plotted said acidity and the acidity found by said pH value, is prepared and then, the acidity of the fruit juice is found by referring to these data. Otherwise, it is read directly by preparing an acidimeter graduated with a logarithmic scale of the acidity corresponding to a pH value scale on an indicator having the same construction as the pH meter. In this manner, the acidity measurement having nearly no measuring error is performed by bringing acidity near to pH 4 by diluting the original liquid of the fruit juice because the pH of nearly all of the original liquid is near 3.5.

The surface temp. of mold material is kept to >= about 700 deg.C and the mold powder having the solidified point lower than the surface temp. of mold material, is used. By this method, the mold powder 3 between the mold 1 and the solidified shell 4 eliminates the solid-phase state and keeps the liquid-phase condition and the air gap layer is reduced. Therefore, reduction of uneven solidification can be realized.

Title: Resin composition and laser marking thereof
Inventor: NARITA HIROSHI
IPC: C08K3/04
Filed: 1984-03-26
Abstract: PURPOSE:A resin composition which, when laser-marked, can give clear, legible, marked characters, prepared by adding a specified amount of carbon black to a specified resin composition. CONSTITUTION:A resin composition prepared by adding 0.5% or above carbon black to a principal component comprising 10-20wt% novolak epoxy resin, 10- 20% phenol novolak resin or cresol novolak resin and 60-80wt% inorganic filler. The marking of a resin-sealed semiconductor device has been conducted by using a thermosetting ink and, therefore, there has been a problem that the marked characters are thinned down by rubbing in the subsequent steps or during handling in packaging or by swelling during solvent washing. Although laser marking is effective in respect of resistance to detachment of marked characters and the index-up of a marking step, it is not yet put into actual use because the marked characters are not legible. By using the resin composition containing carbon black in an amount increased within the scope not detrimental to the function as an electrical insulating material, clear and legible marked characters can be obtained.

CPU 28 obtains a max. value of reading data and corrects the light quantity (gain adjustment) in order to execute optimum reading. Then, shading correction data for correcting the luminous intensity distribution is fetched, so as to start image reading. At the time of the adjustment executing timing, CPU 28 reads the reference density plate so as to correct the light quantity and the luminous intensity distribution. The output current value of a light control inverter 27 is decided, in order to obtain the optimum light quantity at the time succeeding gain adjustment.
