Title: Measurement of melting point
Inventor: FUKAMI AKIRA
IPC: G01N25/04
Filed: 1989-02-08
Abstract: PURPOSE:To enable accurate measurement of a melting point of a substance to be measured by measuring a temperature on the side opposite to the side where the substance to be measured is placed in a heating boat with a radiation thermometer. CONSTITUTION:When a substance 2 to be measured is melted by heat to measure a melting point, the substance 2 is heated upto the melting point by applying a fixed quantity of heat and begins to melt. Under such a condition, as the substance 2 absorbs a melting latent heat, a rise in the temperature of the substance 2 stays at the melting point. Since a temperature of a heating boat 1 corresponds that of the substance 2, the temperature at which the temperature rise of the substance 2 stays is the same as the temperature at which rise in the temperature of the boat stays. Then, a temperature on the side 1B opposite to the side where the substance 2 is placed at the boat 1 is measured to determine a temperature curve with a radiation thermometer 3. On the temperature curve, a so-called thermal arrest indicating the melting point is caused. Thus, the melting point can be measured by checking the temperature at which the thermal arrest is caused.

Title: Oil-pressure circuit for civil and construction machinery
Inventor: OKABE SHINYA
IPC: E02F9/22
Filed: 1981-03-03
Abstract: PURPOSE:To attain travelling and boom operations concurrently and independently by  using a system in which oil pressure is supplied to one running motor through any direction switching valve for travelling, boom, or arm operation in each switching valve  group formed for each oil-pressure pump. CONSTITUTION:In the first switching valve group 39, since a direction switching valve  44 for boom operation is positioned on the upstream side where pressure oil is preferentially received by a direction switching valve 47 for running on the left side, all of  the pressure oil from the first oil-pressure pump 35 is supplied to a boom cylinder 54  through the valve 44 to drive the boom. In the second switching valve 40, since a direction switching valve 49 for running on the right side is positioned on the upstream side where pressure oil is preferentially received by a direction switching valve 52 for boom, pressure oil from the second oil-pressure pump 36 is supplied to a motor 58 for  running on the right side. Because, at the same time, a valve 60 is switched to open  position by an interlocking mechanism B with the action of the valve 44, pressure oil from the pump 36 is supplied through a divergent path oil circuit 59 to the motor 57  for running on the left side by the valve 47. Thus, by driving the motors 57 and 58 by  the pump 36, its independence from the cylinder 54 can be secured.

Filed: 1990-02-13
Abstract: PURPOSE:To enable recording at a pitch between recording elements by altering the range of the elements used for recording at one unit of a plurality of recording elements arranged in a predetermined direction. CONSTITUTION:If a recording head 2 has, for example, 360dpi of resolution to record a line of 1/6 inch by one scanning of a carriage 9, the head 2 needs 60 discharge ports, but 64 ports are here arranged. Further, gears 10a, 10b, etc., are so composed that the minimum sheet feeding pitch of a sheet feed motor 6 becomes 1/90'', i.e., four times of the pitch of arrangement of discharge ports of the head 2. Recording data to be output from an input/output port 104 are supplied to the driving circuit 16 of the head 2 through a selector 18. According to the structure, a recording sheet can be relatively conveyed a pitch shorter than a minimum conveying distance (unit conveying distance) capable of being conveyed by conveying means such as the arranging pitch unit of recording elements.

Title: Manufacturing device for covered cable
Inventor: NISHIDA MINORU
IPC: H01B13/14
Filed: 1989-02-08
Abstract: PURPOSE:To greatly reduce a rotary driving force and make the size of a motor small and compact the motor by installing an inversion driving means of core material which reciprocally inverts at a fixed period while a cable core material is allowed to move it on this side of a covered layer extension molding machine in the direction of its axial center. CONSTITUTION:A core material inversion driving means 9 which makes a cable core material 2 to be reciprocally inverted around its axial center at a fixed period is installed on this side of a covered layer extrusion molding machine while the cable core material 2 is allowed to move in its axial direction. It is possible, therefore, to make the core material 2 to be rotated only in one direction, but also make it to be reciprocally inverted at a fixed period, and when the core material 2 normally turns, this core material 2 is twisted, but when it is reciprocally inverted, the twist is released. That is, if an inversion action is set such that the core material 2 can be reciprocally turned before a resiliency generated in the core material 2 by twisting at the time of normal increases, it is possible to reduce a rotary driving force. Thereby, the motor can be made small in size and compact.

Title: Continuously treating equipment for slag
Inventor: MAGAKI NOBORU
IPC: C04B5/00
Filed: 1978-03-15
Abstract: PURPOSE:To enable a large amt. of molten slag to be treated in a narrow site and to enable the potential heat of the slag to be recovered in cooling by allowing molten slag to flow down onto a circular cooling disc from a spout turning along the disc after which the slag is cooled, solidified and crushed. CONSTITUTION:Molten slag 31 flowing from the upper part of fixed spout 1 is shifted to turning spout 2 turning clockwise on circular cooling disc 5 with turning stand 15. Next slag 31 flows down from the tip of spout 2 onto disc 5, and it is thinly extended owing to the inclination of disc 5 and cooled with cooling water flowing through cooling pipes 6. The extended molten slag is solidified to solid slag while giving most of its potential heat to the disc and releasing part of the heat into the air. A thin layer of solid slag 31a is then crushed with crushing roller 19 rotating on the layer as stand 15 moves. Ballast 31b formed is discharged with scraper 22 toward the center of disc 5.

Title: Method for encoding, transmuting and receiving 10-bit data byte and transmission equipment for 10b/12b mode
IPC: H03M7/14
Filed: 1993-02-19
Abstract: PURPOSE: To encode a packet of 10-bit width to a 12-bit code by separating 10-bit raw data as well as performing encoding, while using a 5B/6B code. CONSTITUTION: In response to an 8-bit/10-bit control on a line 20, in a 10-bit mode, a multiplexer 31 sends two 5-bit nibbles to a 5B/6B encoder 32. The 6-bit code output of the encoder 32 is sent to a port 2 of a multiplexer 34 and transferred to a serial shifter 36. Under control 20, the multiplexer 34 is locked to the port 12 in the 10-bit mode. An execution disparity/inversion control circuit 35 receives a 2-bit input. Encoders 32 and 33 calculate the disparity of nibbles, send the result to the circuit 35 and update the execution disparity calculation of a serial data stream. In 10B/12 mode, data are shifted serially from a shifter 36 for the unit of 12 clocks. A synchronous padding circuit 38 instructs shift to 10B/12B mode.
