Title: Semiconductor ic device
Inventor: TOMARI NAOSADA
IPC: H01L27/06
Filed: 1981-10-28
Abstract: PURPOSE:To provide a filter in a substrate particularly without using an external mounted element, by making the cut-off frequency of a transistor which constitutes a filter circuit in one Si substrate lower than the cut-off frequency of the transistor which constitutes other circuit. CONSTITUTION:An N type epitaxial layer 2 on a P type Si substrate 1 having an N<+> buried layer 4 is isolated by P layers 3 and 5, a P layer 6 is provided on an island 2B, a new SiO2 film 8 is opened, and thus a P layer 9 is formed shallower than the layer 6 on an island 2A. The donor is diffused simultaneously over the entire surface resulting in the simultaneous formation of a transistor Q1 at a P base 9, an N<+> emitter 10 and a P<+> collector lead-out part 11 and a transistor Q2 at the P base 9, an N<+> emitter 12 and an N<+> collector lead-out part 13. Succeedingly, a window is opened on an SiO2 film 8, and an electrode 15 is laid. Since the junction of a Q2 base layer for low-pass is deep, and the depths of Q1 and Q2 emitter junctions are the same, the Q2 base width is wide resulting in the decrease of the shield frequency fT. When Q1 and Q2 are connected to a wave detector, a filter circuit is formed. When a Darlington circuit is constituted by combining the Q1 for a general circuit and the element of the same constitution, the decrease of hFE of the Q2 can be compensated.

Title: Evaluation function arithmetic circuit
Inventor: OTA SHINJI
IPC: H04L7/027
Filed: 1989-07-04
Abstract: PURPOSE:To miniaturize the circuit by providing a numerator arithmetic section calculating the numerator of an evaluation function based on a reception signal and a memory calculation section, multiplying an output of the numerator arithmetic section and the memory calculation section so as to calculate of the fractional number of the evaluation function. CONSTITUTION:A reception signal X is subject to line distortion equalization by an equalizer 2, inputted to an identification device 3 and a sample circuit 4, for which a reception symbol An and a reception signal Xn are generated and calculated over one averaging period by multipliers 12, 13. On the other hand, a symbol + or -1 counter 11 counts number of symbols of + or -1 level in the symbol An over one averaging period. Since the symbol An is of + or -3 level when not in + or -1 level, the denominator of the evaluation function over one averaging period depends definitely on number of + or -1 levels in the symbol An over one averaging period. Then the output of the counter 11 is used as the address to read a reciprocal of the denominator of the evaluation function from a ROM 14. Thus, the capacity of the ROM 14 is remarkably reduced.

Title: Thrust roller bearing
Inventor: CHIBA MOICHI
IPC: F16C33/46
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To provide a thrust roller bearing with improved reliability by a simple structure. SOLUTION: A holder 10 holds a race 103, and is projected to the race 103 to form a projection 101e to prevent axial relative movement of the race 103. The race 103, directly abutting against a roller 102 without the holder 101 therebetween, has a conical part 103a for regulating radial movement of the roller 102, therefore, radial force transmitted from the roller 102 is not transmitted to the holder 101. The projection 101e formed on the holder 101 is thus prevented from being slidably contacted with the race 103. Separation between the race 103 and the holder 101 is thus prevented.
