Abstract: PROBLEM TO BE SOLVED: To provide an elastic nonwoven fabric which has excellent elasticity, a good skin touch, and an excellent heat sealing property, and is suitable for sanitary materials such as diapers, disposable underwear, supporters, cataplasm base fabrics, and the like. SOLUTION: This elastic non-woven fabric having an excellent heat sealing property is obtained by applying a high pressure fluid treatment to a fiber web comprising latent crimpable conjugate fibers 1 and thermally adhesive fibers to three-dimensionally interlace the constituting fibers each other and then thermally treating the interlaced fiber web at a temperature not thermally adhering the constituting fibers each other, thereby expressing the three- dimensional crimps of the latent crimpable conjugate fibers 1. The latent crimpable conjugate fibers 1 comprise two or more kinds of polymers having different melting points, respectively, and express the three-dimensional crimps 2, when thermally treated.  The thermally adhesive fibers have a higher melting point TBL( deg.C) than a temperature T( deg.C) at which the latent crimpable conjugate fibers 1 express crimps in an amount of >=17 crimps/25 mm.

Title: Production of pyranoindolizindione derivative
IPC: C07D491/22
Filed: 1992-03-27
Abstract: PURPOSE:To obtain a racemic modification of a pyranoindolizindione derivative useful as an intermediate for an anticancer agent in high yield and purity by effectively reutilizing a useless substance formed as a by-product in producing a camptothecin derivative useful as the medicine. CONSTITUTION:A racemic modification of formula 1 is optically resolved to produce an optically active substance (S-isomer) of formula 1-S useful as an intermediate for a compound of formula 4 (an anticancer agent). A useless optically active substance (R-isomer) of formula 1-R formed as a by-product in the process is made to react with a halogenating agent such as thionyl chloride in an inert solvent at -20 to +60 deg.C temperature to afford a new halogen derivative of formula 2 (X is halogen atom), which is then hydrogenated in the presence of a reducing agent such as n-Bu3SnH or a hydrogenation catalyst such as Pd-C in an inert solvent. Oxygen gas is then introduced into the resultant compound of formula 3, preferably without isolation, in the presence of an alkali metallic alcoholate and a trialkyl phosphite, etc., in an inert solvent to oxidize the compound of formula 3. Thereby, the objective racemic modification of formula 1 is industrially and advantageously obtained. Furthermore, the racemic modification can be utilized as an intermediate for the compound of formula 4.

Filed: 1983-04-21
Abstract: PURPOSE:To improve the system performance by writing a signal of a single frequency higher than the basic clock frequency written to an indicator part to a part of a data part to record a file mark and writing a single frequency to the rest of the data part to erase the file mark respectively. CONSTITUTION:When a file mark is written to a data part D, a mark write pulse MWPb is produced in place of a write gate pulse (a) and supplied to a timer circuit 22 through an OR gate 28 to produce a gate signal (e). The signal (e) opens an AND gate 14 and is written to a data part after detection of a disk medium 10 to be used as a file mark. When this file mark is erased, an index and an address are detected. Then a mark erasion pulse (c) is produced in the timing equivalent to the middle of the data part. An approximately entire area of the data part is written with the pulse (c) together with the file mark written previously with a division output (f). Thus the file mark is erased.

Inventor: ABE TAMIO
IPC: G01R31/26
Filed: 1990-03-20
Abstract: PURPOSE:To prevent a hybrid integrated delay line having a different delay time from being mixed into a production process by measuring a delay time between a reference pulse signal generated from a pulse signal source and a delay pulse signal delayed from the reference pulse signal by a hybrid integrated delay line and deciding the validity of the delay line based upon the measured value. CONSTITUTION:A rise time difference or fall time difference between a reference pulse signal and a delay pulse signal is counted by a counter and the counted value is outputted to monitor 5 through a decision signal line 9. The measured results of a reference pulse signal waveform and a delay pulse signal waveform are observed by the monitor 5 and the delay time of the hybrid integrated delay line 3 is recognized.

Abstract: PURPOSE:To control the concentration of toner automatically and accurately at any time by detecting and storing the density of reference toner as a reference value and comparing the concentration of a developer during operation with the reference density. CONSTITUTION:A developer adjusted to accurate concentration when a copying machine is installed is stored as the reference toner concentration in a RAM 77 by outputting a signal from an oscillator 26 from a magnetic sensor 25 to a detector 27 as variation in the magnetic permeability in a developer and then passing the signal through a microcomputer 70.
