Title: New 15-membered cyclic compound and its production
Inventor: TAKAHASHI TAKASHI
IPC: C07C49/587
Filed: 1992-09-09
Abstract: PURPOSE:To produce the subject new 15-membered cyclic compound useful as a raw material for efficiently producing muscone as an aromatic component of musk at low cost by carrying out ring closure of a specified long-chain unsaturated nitrile compound under a basic condition. CONSTITUTION:After protecting the aldehyde group of 7-octenal of formula I by acetalation and lengthening the carbon chain by a hydroformylation reaction, this compound is converted to an aldehyde ester compound of formula II (R2 is an alkyl, etc.) by the Horner-Emmons reaction and then reduced. A hydroxyl group is introduced into the terminal and the introduced hydroxyl group is substituted with an eliminable group. The terminal ester group is subsequently reduced to obtain a compound of formula III (X is an eliminable group). Acetal form of senecioaldehyde is then reacted therewith and trimethylsilyl cyanide, etc., is subsequently reacted therewith. The hydroxyl group of the resultant cyanhydrin compound is etherified and the obtained compound of formula IV (A is, e.g. a group of formula V; R is an alkoxyethyl) is subjected to ring closure under a basic condition, thus producing the objective 15-membered cyclic compound of formula VI.

Title: Atm network
Inventor: YOKOYA TETSUYA
IPC: H04L12/56
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To enable a communication management system to quickly cope with the load change of a network by generating an RM cell as well as a user data cell, calculating the ER(explicit rate) value based on the algorithm accordant with the QL(queue length), updating an ER field in the RM cell and then returning the RM cell. SOLUTION: In an ATM(asynchronous transfer mode) network 24 having a switch 26, an originator system 10 generates a data cell 12 as well as a forward RM cell 14. A switch 26 calculates the ER value based on the algorithm accordant with the QL and updates an ER field in the cell 14. Then the switch 26 writes the network retard information into both or one of forward and backward RM cells 14 and 18. A destination system 22 consumes the cell 12, converts the cell 14 into the cell 18 and sends the cell 18 back to the system 10 via the network 24.

Title: Displacement element
Inventor: WATANABE JUNICHI
IPC: H01L41/083
Filed: 1987-10-26
Abstract: PURPOSE:To obtain an excellent temperature characteristic by a method wherein two or more electrostrictive elements or piezoelectric elements whose Curie temperature value differs from each other are combined and laminated. CONSTITUTION:Two or more kinds of electrostrictive elements or piezoelectric elements whose Curie temperature value differs from each other are formed to be thin sheets; these thin-sheet elements are laminated; electrodes to be used to impress a voltage are installed at each thin-sheet element. When the voltage is impressed on this displacement device via the electrodes, each thin-sheet element of the electrostricitve elements or piezoelectric elements is displaced individually; accordingly, a large displacement value of the displacement device is obtained as a whole. In this case, because the two or more electrostrictive elements or piezoelectric elements constituting the displacement element contain the elements whose Curie temperature value differs from each other; a temperature at which a maximum displacement value is obtained is not definite at each thin-sheet element. By this setup, even when the temperature is changed, the thin-sheet electrostrictive elements or piezoelectric elements display the maximum displacement value at each temperature; accordingly, even when the temperature is changed, a nearly uniformly large displacement value of the two or more thin-sheet elements is obtained at the respective temperatures as a whole.

Abstract: PURPOSE: To separate the frequency components of noise due to the recess and projection on road surface and the vibration of vehicle suspension by using a means for detecting the rotary speed of a wheel at a region which is different from that of the frequency component of noise. CONSTITUTION: When a wheel 10 rotates, a flange 11 and a shaft 12 also rotate and the shaft of a rotary encoder 14 (rotary speed detection means) also rates via a shaft joint 13. Then, a circular disk with a slit in the encoder 14 rotates and pulses are outputted from the encoder 14 according to the speed of the rotary disk. With the encoder 141, the frequency component of the rotary speed of the wheel are set to a high frequency so that they differ from the frequency component of the noise at a relatively low frequency due to the recess and projection on the road surface and the vibration of a suspension and for example 1,000 pulses are outputted per revolution of the wheel 1. Also, since the encoder 14 is fixed to the wheel, mounting stays 17 and 18 and a stay connection means 19 and a supporting means 16 support the encoder 14, thus achieving the mounting on the vehicle afterward.

The center point of the wafer map is determined by a corner points. Curves 310 and 312 indicate the number of chips obtained by changing the peripheral rejectable area by fixing the center point of the wafer map. In addition, a curve 410 is obtained by multiplying a probability curve 314 by the curve 310, and a curve 412 is obtained by multiplying the curve 314 by the curve 312. The chips in the rejectable area are accepted when the yield probabilities of the chips are larger than as assigned threshold.
