Abstract: PROBLEM TO BE SOLVED: To increase the vacuum degree in an oil tank and conservator. SOLUTION: Through suction valve 26 of the conservator 25, an oil tank 21, conservator 25 and a rubber bag 27 are evacuated.

IPC: G11B15/60
Filed: 1984-04-13
Abstract: PURPOSE:To obtain an excellent tape running characteristic even at humid atmosphere with less tape damage by coating a thin layer of titanium oxide ceramic to a magnetic tape sliding face. CONSTITUTION:For example, a tension post 15, tilt post 17 and a tilt post 23 among members of a tape running system are formed by coating a thin layer of a titanium oxide ceramics being a sintered body taking a rutile (TiO2) use as a major component to an outer circumferential face (tape sliding face) of a mother material made of a stainless steel. Moreover, a drum 22 is formed by coating a thin layer of titanium oxide ceramics to the outer circumferential face of the mother material of a drum shape made of aluminum or plastic. Thus, even if the tape winding angle to the post is large, the friction coefficient at the surrounding of the post is less and the wear of both posts and tape is very less.

Title: Nonvolatile semiconductor memory device
Inventor: HAYAKAWA TOSHIYUKI
IPC: H01L21/76
Filed: 1993-04-01
Abstract: PURPOSE:To prevent a threshold value of a selective transistor from rising by forming a channel stopper layer of an element isolation region of a selective transistor whose concentration is lower than the concentration of a channel stopper layer of an element isolation region of a memory cell transistor. CONSTITUTION:Impurity concentration of a channel stopper layer 102 of a region 10 (a region including a source side selection line SL2) lower than impurity concentration of a region 11 (a region including a word line WL and a drain side selection line SL1). Thereby, element isolation between adjacent memory cells of higher breakdown strength is possible. As a result, enough element isolation is possible in a channel stopper layer of low concentration immediately below a source side selection line and a narrow channel effect is not generated in a source side selection transistor. Since series resistance during read of a NAND-type memory cell lowers and discharge velocity of a bit line is made rapid, rapid read becomes possible. Furthermore, false read is reduced.

Title: Phenol resin-laminated board and manufacture thereof
Inventor: MATSUOKA HIROYUKI
IPC: B32B27/42
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To dispense with a halogen flame retardant, and advance a flame retardancy, soldering heat resistance, and punching workability by blending microcapsules of phosphoric ester in a phenol resin-laminated board. SOLUTION: The phenol resin laminated board is blended with microcapsules of phosphoric ester in order to have a superior flame retarding property without the use of a halogen flame retardant. For such a compound to be encapsulated, an amino resin of melamine and a melamine resin is desirable in order to permit a flame retarding property of the laminated board to perform effectively. As a phosphoric ester, triphenylphosphate, cresyldiphenylphosphate, and tricresylphosphate are preferable because of its wide application in aspect of cost. By blending microcapsules of the phosphoric acid ester in phenol resin varnish, there is no loss of the phosphoric ester in a drying process, so that flame resistance is exerted sufficiently.

The track width is regardless of the thickness of the ferromagnetic metallic thin films in this way and the track width of the high accuracy is obtd. even if a wafer is formed to a larger size. The productivity is thus enhanced.

Title: Automatic gain control circuit
Inventor: KAMIYAMA TAICHIROU
IPC: H04B1/16
Filed: 1980-06-06
Abstract: PURPOSE:To realize a sufficient control of gain even at a particularly high input signal level, by adding a control circuit for attenuation quantity of RF band signal to a heterodyne receiver which gives an automatic control to the gain of the intermediate frequency band and at the same time controlling the gain of the RF band. CONSTITUTION:The input signal Sin of the RF band is supplied to a received frequency converter 21 with a preintermediate frequency amplifier through an attenuation quantity control circuit 33 and then sent to a main intermediate frequency amplifier 22 after receiving a frequency conversion by the output of a local oscillator 25. A part of the output Sout of the amplifier 22 receives a negative feedback from a DC amplifier 23 with rectifier to the amplifier 22 and is also sent to a control amplifier 32. The amplifier 32 increases a control signal S2 when the input Sin of RF band exceeds the standard received input level set by a variable resistance Rv. Thus an RF signal attenuating circuit 31 has an attenuating action. In such way, the signal Sout is controlled at a certain level like in the case of 36 although the signal Sin increases.
