Title: Fuel cut control device for internal combustion engine
Inventor: TANEI KATSUTOSHI
IPC: F02D41/12
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To provide a fuel cut control device for an internal combustion engine to suitably maintain drivability when fuel cut control is executed during engine light load operation on a downward slope. SOLUTION: An electronic control device 23 decides it based on the number of revolution of an engine and a fuel injection time whether an operation state is in a fuel cut region. Based on a change amount of an accelerator opening and a change speed, a transfer region between a fuel cut region and a fuel feed region related to execution or return to fuel cut is set to either a region where a natural return hardly occurs or a region where natural return is easy to make. Namely, when a change amount and the change speed of an accelerator opening exceed a given value, a small transfer region is set and transfer from a fuel cut region to a fuel feed region is facilitated.  Meanwhile, when a change amount and the change speed of the accelerator opening are below a given value, a large region is set, and transfer from a fuel cut region to a fuel feed region, i.e., a natural return, is made difficult to be performed.

Title: Manufacture of permanent magnet
Inventor: YANAGIMOTO MASARU
IPC: H01F41/02
Filed: 1988-08-16
Abstract: PURPOSE:To efficiently manufacture a permanent magnet whose mechanical strength and magnetic characteristic are excellent by a method wherein a permanent-magnet metal powder is filled into a malleable metal container and is sealed hermetically, it is heated together with the container and it is compressed and sintered under a specific pressure. CONSTITUTION:During a heating process and a compression and sintering process to be executed after it, a powder at the inside is shut off from the outside by a container and is not oxidized. As a result, a non-oxidizing atmosphere is not required; accordingly, these processes can be executed by using facilities of a simple structure. When the container in which the powder has been enclosed is heated in advance by other means during the compression and sintering process, it is not required to heat a metal mold for pressurization use up to a treatment temperature; accordingly, it is possible to easily obtain a pressure of 2000kg/cm<2> or higher which is hard to realize in an industrial process. Thereby, it is possible to obtain a tough and high-density product where a void is hardly contained.

Title: Printing pressure control method and device in ball-type-head-typewriter
Inventor: KURAMITSU WATARU
IPC: B41J7/92
Filed: 1984-09-28
Abstract: PURPOSE:To reduce the number of parts, eliminate operational defects and prevent structural scale-up in size by controlling printing pressure of a printing member without changing the position of balls, using as single cam rotating at a fixed position and a rotary element being engaged with an electromagnetically actuated slider. CONSTITUTION:A printing member 26 is energized counter-clockwise by a spring 84 having a weak resilient force. A locking block 50 is locked an elongation part 42 of a rotary lever 36 and therefore, its motion is restricted, resulting in the movement of a roller 34 in an arrow direction 78 by the force of a spring 32 when the roller 34 comes to a position where it is engaged with a concave part 76. If a rocking lever 24 rotates in an arrow direction 78 due to the high elasticity of the spring 32, the lever 36 rotates in an opposite direction to an arrow direction 74 around an axis 30, and a locking piece 50 of the printing member 26 is unlocked. Subsequently, an axis 18 is turned clockwise and a printing ball 12 touches a platen 14, ending a printing operation. Thus a slider 54 need not return to a home position every time it completes printing, so that rapid operation is achieved and a uniform printing condition is obtained.

Title: Combustion controller of refuse incinerator
Inventor: KAWATO KIYOYUKI
IPC: F23L15/00
Filed: 1996-08-02
Abstract: PROBLEM TO BE SOLVED: To precast future combustion state and perform continuously stable refuse combustion control by providing a refuse incinerator with a temperature control means which adjustes the heating temperature of combustion gas, based on the refuse surface temperature detected by an infrared ray detection means. SOLUTION: An infrared ray camera I takes a photograph of an image having passed through a filter and an image not having passed through the filter, and this judges the area where the temperature difference on a drying zone 6 in both images is detected to be the ignition area, and judges the area with a specified width just on its upstream to be the ignition start area, and seeks the average value of the refuse surface temperatures in the image through the filter of that area. Then, A temperature control means 30 performs the temperature adjustment of air by a heat exchanger T, based on the obtained average value.  In the case that the condition where the average value is lower than the lower temperature side reference temperature continues for a specified time, the shift to an incomplete combustion condition is avoided by raising the air temperature, depending upon the degree, from about 150 deg.C to 200 deg.C so as to accelerate the drying and combustion of refuse.
