Title: Preparing iron powder and ferrocobalt alloy powder for magnetic tape
Inventor: YOSHIZUMI MOTOHIKO
IPC: G11B5/706
Filed: 1978-12-19
Abstract: PURPOSE: To obtain powder with high magnetic flux density and strong magnetic reluctance by reducing iron oxide with its original spicular form left, using organic matter as reducing agent, in such a process as to agglutinate adhesive organic matter on the surface of spicular iron oxide powder and heat it in a reducing and other ambience.  
     CONSTITUTION: Adhesive organic matter such as cellulose acetate, ethyl cellulose or styrene is agglutinated on to the surface of the spicular powder of iron oxide or Co-containing iron oxide, which is heated in the ambience of reducing gas or inert gas or in vacuum in a comparative low temperature less than 500°C. Ferro-oxide powder is reduced by the help of agglutinated organic matter as the reducing agent. By using iron powder with high magnetic flux density and strong magnetic reluctance obtained through reduction of iron oxide powder with spicular form left in this way, the frequency characteristic of magnetic tape can be improved.

Title: Vacuum double layer glass and its manufacturing method
Inventor: ASANO OSAMU
IPC: E06B3/66
Filed: 1996-06-17
Abstract: PROBLEM TO BE SOLVED: To lower the melt position of a glass short pipe and to prevent colli sion of a protrusion with a sash frame during opening of a window by a method wherein a shield member is attached in the middle of the glass short pipe to exhaust the air in the space between two glass plates. SOLUTION: First and second glass plates 2 and 3 are sealed along the peripheries through a spacer and the air in the space between the glass plates is exhausted through a glass short pipe 7 attached on the main surface of the first glass plate 2. The outlet of the glass short pipe 7 is molten and closed in a vacuum space. In this case, a shield member formed of a metal, a precious metal, or a refractory, and infrared rays generated during melting are blocked so as to reach in short of a solder glass 8 and the first glass plate 2 at the periphery thereof. Thereby, the melt position of the glass short pipe 7 is caused to approach the first glass plate 2 and a height (h) of a protrusion end 7a is prevented from exceeding 3mm.

Title: Air-fuel ratio controller for internal-combustion engine
Inventor: IEZUKA ISAMU
IPC: F02D41/04
Filed: 1982-09-09
Abstract: PURPOSE:To enable to appropriately control an air-fuel ratio, by controlling the injection quantity of a fuel so that the ratio of the quantity of intake air and the quantity of a fuel injected is equal to a theoretical air-fuel ratio in an open loop control period wherein fuel temperature is low and that said ratio is equal to a lean-side air-fuel ratio in an open loop control period wherein the fuel temperature is high. CONSTITUTION:In step 40, the subsequent steps are entered only in the case of a non- idle period. In step 41, the subsequent steps are entered only in the case of an open loop control 42. When the fuel temperature in a fuel tank 23 in lower than a predetermined value T in step 43, on injection quantity of the fuel is so calculated that a normalized air-fuel ratio lambda (air-fuel ratio/theoretical air-fuel ratio) 1 in step 44. On the other hand, in step 45, the injection quantity of fuel is so calculated that lambda>1. The ratio lambda is the ratio of the air-fuel ratio calculated from only the quantity of the fuel injected through a fuel injection valve 1 to the theoretical air-fuel ratio. Accordingly, the quantity of the fuel injected through the valve 11 is reduced as the quantity of a fuel vapor discharged through a purging port 10 is larger, and the ratio of the quantity of intake air to that of the fuel supplied in total is maintained at the theoretical air- fuel ratio irrespectively of the quantity of the fuel vapor discharged.

Abstract: PROBLEM TO BE SOLVED: To improve the operating convenience of the radio equipment by using a microcomputer so as to compare a detected value of a reception electric field strength with a voltage of a prescribed threshold level corresponding to a weak electric field strength and selecting automatically a voice frequency through microcomputer control so as to conduct excellent communication up to a weak electric field strength without a troublesome operation. SOLUTION: When a reception electric field strength is sufficiently high, a microcomputer 9 controls a changeover circuit 8 to make the changeover circuit 8 conductive and a position of a capacitor 7 leading to the changeover circuit 8 is connected to ground. Thus, a frequency component subject to band limit by a reception voice signal processing section 1 is outputted as it is from a voice signal output speaker. When the reception electric field strength is weak, the microcomputer 9 controls the changeover circuit 8 to make the changeover circuit 8 nonconductive and a position of the capacitor 7 leading to the changeover circuit 8 is not connected to ground. Thus, the cut-off frequency of a high frequency pass filter is decided by a quantity 5 and a capacitor 6 only.
