Title: Automatic end point detecting device
Inventor: SUZUKI SEIJI
IPC: H01L21/302
Filed: 1988-11-21
Abstract: PURPOSE:To prevent emission spectrum strength from varying fractionally and to detect an end point surely without false detection by performing correction operation for emission spectrum strength by a pressure. CONSTITUTION:One of factors of fractional variations of emission spectrum strength is variations of pressure inside a treatment chamber 1. Therefore, it is possible to eliminate the variations if relationship between a pressure and an emission spectrum strength is acquired in advance and an operation device 4 performs correction operation for an emission spectrum strength which a spectrum sensor 2 detected by a pressure detected by a pressure sensor 3. Since the little by little variations of emission spectrum strength waveform is thereby eliminated, false detection of an end point is also eliminated, thus eliminating the necessity of neglecting variations. False detection of failing to detect an end point can be prevented in this way.

Title: Shell type needle roller bearing
Inventor: UCHIUMI YASUO
IPC: F16C33/62
Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To improve the bearing service life, and to improve an acoustic characteristic by forming an orbital plane after press molding by using low carbon steel having a specified crystal grain size. SOLUTION: A shell type needle roller bearing is used under a condition where roughness of a contact surface of a bearing ring with a needle roller is generally largely different. That is, from a material of the bearing ring, almost same roughness (Ra=0.06 to 0.07 μm) is obtained regardless of the crystal grain size as illustrated, but in a pressed bearing ring, roughness is large in the one having the large crystal grain size, and is remarkably large when the crystal grain size is not more than about No. 7. Thus, in a work surface having bad roughness, a projection becomes a stress concentration source, and becomes a cause of reducing the service life and an acoustic characteristic.  Therefore, when low carbon steel having the crystal grain size not less than JIS No. 8 is used as a material of the bearing ring, a bearing ring having an excellent roughness orbital plane can be obtained.

Title: Latching comparator to compensate offset voltage
Inventor: KASE KIYOSHI
IPC: H03K5/08
Filed: 1988-11-24
Abstract: PURPOSE:To improve and compensate an offset voltage during comparation operation by storing offset information in two capacitors during offset sampling. CONSTITUTION:The both sources of electric field effect transistors Q2 and Q3, which form a first differential pair, and connected to an N-channel electric field effect transistor Q1 which is a common constant current source. Then, the transistor Q1 is controlled by a bias voltage input BI. Since an inverted input IN is the offset sampling, the input is executed through an N-channel electric field effect transistor Q9 to the gate of the electric field effect transistor Q3 as well. When a high level is given to a clock inverted input EN, the N- channel transistor Q9 is turned on and a gate input IP of the electric field effect transistor Q3 goes to be the same level as the inverted input IN. Then, the offset sampling can be executed. Thus, the offset voltage can be easily compensated without increasing die cost.

IPC: G21B1/00
Filed: 1985-12-25
Abstract: PURPOSE:To obtain a sealing condition with high reliability by a simple work by disposing a sealing member composed of a form memory alloy between first and second joined members. CONSTITUTION:In a fusion reactor, in a state that the cross-section of an O-ring 101 disposed on access door 7 side is memorized in a circular form, the access door 7 is attached and fastened to an access port 8 by means of a bolt 107. At this time, the O-ring 101 is deformed in an elliptical form in its cross-section by the fastening force of the bolt 107 and in cases where the O-ring is in a martensite phase, the cooling medium having the temperature of not less than Af is introduced into piping 105 through a penetrating aperture 104 and sprayed to the O-ring 101 through a penetrating aperture 106. Thus, since the O-ring 101 returns from a martensite phase to a mother phase and its cross-section returns to a circular form, it makes close contact with the access door 7 and the access port 8. Therefore, a certain sealing state can be obtained without needing any complicated work.
