Filed: 1984-03-23
Abstract: PURPOSE:To uniformize the thickness and the pattern dimensions of a resist film by arranging nozzle tips on a line containing the center and a part of the periphery of a wafer and dripping a developing solution onto the wafer simultaneously. CONSTITUTION:A plurality of nozzles 9 are fixed with a plate 10 with their tips arranged in the radial direction of a wafer. The space between two nozzles may be 5mm. or less.

Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To arbitrarily give a lattice distortion so as to have large spontaneous polarization and a small resist field, by using a ferroelectric substance thin film of perovskite structure, and substituting an element of different ion radius. SOLUTION: A crystal structure of ferroelectric substance thin film of stratified structure superposing six single lattices of perovskite structure is constituted by using an element Bi in site A, element Sr in site B and element Ta in site C. That is, by combining an element of different ion radius with sites A, B constituting a crystal lattice and site C generating polarization in the ferroelectric substance of perovskite structure, an arbitrary large distortion is given to the crystal lattice. As a result, a ferroelectric substance thin film having high spontaneous polarization and small resist field can be utilized as a ferroelectric substance element of structure interposed by an electrode.

Title: Process for producing 1,4-diazacycloheptan-2-one from alkylated diamine mixture
Inventor: JIYON TAAYUAN RAI
IPC: C07D243/08
Filed: 1991-01-07
Abstract: A process is disclosed for making a 1,4-diazacycloheptan-2-one from a mixture ('first' mixture) of alkylated 1,3-propanediamines one of which (referred to as the 'target' diamine) has substituents at specifed positions and contains (i) a terminal primary amine group adjacent to a disubstituted C atom (hence, referred to as having a 'hindered' N atom), and (ii) a terminal secondary amine group. The target diamine, other diamines and oligomeric polyamines in the first mixture, are made by alkylating an acyclic ('starting') 1,3-propanediprimaryamine having the hindered N atom. The first mixture of alkylated diamines, preferably containing a major molar proportion of the target diamine relative to any other alkylated diamines, is reductively alkylated, which unexpectedly results in the reductive alkylation of only the unwanted diamines, allowing the target diamine which is not reductively alkylated, to be removed from the mixture of reductively alkylated diamines. Upon cyclization of the target diamine, using the "ketoform reaction", it is essentially quantitatively converted to the 1,4-diazacycloheptan-2-one having an unsubstituted N<4> atom flanked by disubstituted adjacent C atoms. By removing the unwanted components in the reaction mass an essentially pure product of 1,4-diazacycloheptan-2-ones is recovered. Thus, the difficulty of separating the target amine from other close-boiling compounds is avoided. As an alternative, the reductive alkylation step can be bypassed and the first mixture subjected to the ketoform reaction, followed by recovery of the desired product.

Title: Serial data transfer circuit
Inventor: YAMAGUCHI AKIRA
IPC: H03K5/135
Filed: 1985-03-20
Abstract: PURPOSE:To reduce the power consumption by providing plural rows of shift registers connected in series and supplying data to shift registers in the first stages of individual rows in time division to reduce the number of inversions of shift registers. CONSTITUTION:n-number of shift registers are divided to k-number of groups each of which consists of m-number of shift registers connected in series. Common data is given to shift registers in the first stages of k-number of groups and is inputted there in time division by shift pulses phii (i=1-k) different in phase. Inputted data is transferred to shift registers in the same group successively synchronously with the shift pulse of each group. Data transferred to registers in the last stages of individual groups are led out through transfer gates T1-Tk and T0. Thus, the number of inversions of each shift register is reduced to 1/k. Consequently, the power consumption is reduced.

Filed: 1988-03-10
Abstract: PURPOSE:To transmit and receive an electric signal with high reliability by laying a superconductor under the ground and making the laid superconductor into the reference potential network between pieces of electric equipment installed in different spots. CONSTITUTION:A superconductor 5, which is laid and extended under the ground of the areas of main places in the whole of Japan so that it can cross the main places, composes the reference potential network to be a return circuit for the signal circuit between respective telephone sets 1 as the pieces of electric equipment installed in the respective main places.
