Title: Oxygen sensor
Inventor: KAJIMA TAKAFUMI
IPC: G01N27/41
Filed: 1990-04-24
Abstract: PURPOSE:To make it possible to attract mist electrically to an insulating material, and prevent the attachment of the mist to the inner surface of a gas diffusing hole to deform the hold by using the insulating material wherein electric charge can be built up for the surface of a space forming material on the side facing a space part. CONSTITUTION:An insulating layer 10A wherein electric charge can be built up is provided on the surface of a space forming material on the side facing a space part. When, e.g. corrosive mist is contained in a sample gas which is introduced through a gas diffusing hole 1A, the mist can be a electrically attracted to the insulating layer 10A. Thus, the attachment of the mist on the inner surface of the gas diffusing hole 1A and the deformation of the hole can be prevented. The characteristics of a limiting current are always kept in the same state, and the measurement of the concentration of oxygen can be accurately performed, and the service life can be prolonged.

Abstract: PROBLEM TO BE SOLVED: To obtain a product having the precision equaled to a fine blanking method by shaping the shear droop part of a rough-blanking by a plane pushing forming a tooth shape and thereafter, executing a finish-blanking (shaving). SOLUTION: The blanking shear droop part 1a developed in a first semi- worked product 1 blanked to the shape and the dimension near the product with the rough blanking, is plane-pushed and round part 1b is formed to obtain a second semi-worked product 2 having the normal shape on the upper and the lower surfaces of a tooth part. At this time, the volume V1 of the blanked shear droop part 1a in the first semi-worked product 1 is almost equaled to the sum of the formed volumes V2, V3 at the upper and the lower parts of the tooth part with the plane pushing. That is, in the ideal condition, this relation is made to V1=V2+V3.  Further, therefore, in the rough-blanking process, the clearance in a die is gradually enlarged from a dedendum part toward an addendum part and the deformed volume of the tooth part is uniformized in an extruding process and also, made narrower than the width near the addendum process of the first semi-product 1 to uniformize the deformed volume in the finish-blanking process. Finally, the finish-blanking to the outer peripheral part of the second semi-product 2 is executed to obtain the product 3.

This cup 7 is removed after the working. According to this method, there will be no melt left in the hole at all, whereby clogging is fully prevented, and the accuracy of piercing is cnsiderably improved.

Filed: 1992-04-28
Abstract: PURPOSE:To reduce delay by transmitting an (m)-bit parallel information signal, which is not synchronized with a transmission line signal, as an (n)-bit parallel signal by stuff synchronization. CONSTITUTION:A transmission line signal multiplexing part 13 is provided in the transmitter 2, and a transmission line signal demultiplexing part 17 is provided in the receiver 6. Then, mn/(m-n) bits of the information signal which is the least common multiple of the numbers (m) and (n) of the bits of the signal are separated by the transmission line multiplexing part 13 of the transmitter 2 into n<2>/(m-n) bits of the high-order (n)-bit part of the information signal and (n) bits of the low-order (m-n)-bit part of the information signal, and both the signals are multiplexed on a time-division basis and converted into the (n)-bit parallel transmission line signal, which is outputted. The transmission line signal demultiplexing part 17 of the receiver 6 separates the mn/(m-n) bits of the transmission line signal and restores the signal to the (m)-bit parallel information signal. Thus, the (m)-bit parallel information signal is transmitted by the stuff synchronization by using an (n)-bit parallel transmission line.

They are given to the first and second storage control means 9 and 11. In the former, picture element data is read every (n) picture elements and every (m) lines.  In the latter, addresses are generated every (n) picture elements and every (m) lines.
