Title: Preparation of polyamide
Inventor: TOYODA TOSHIHIRO
IPC: C08G18/34
Filed: 1981-07-20
Abstract: PURPOSE:To prepare a polyamide having high polymerization degree, with improved rate of reaction and low deterioration of the polymer, by reacting a specific di-, tri- or tetra-carboxylic acid with a diisocyanate in the presence of an alkali metal (bi)carbonate. CONSTITUTION:A polyamide containing at least one recurring unit of formula VII-IX is prepared by polymerizing (A) at least one di-(tri or tetra)carboxylic acid of formulaI, II or III (e.g. adipic acid, pentane-1,2,5-tricarboxylic acid, butane-1,2,3,4-tetracarboxylic acid, etc.) with (B) at least one diisocyanate of flumula IV (e.g. 1,2-diisocyanatoethane) in the presence of an alkali metal (bi) carbonate of formula V or VI (e.g. lithium carbonate) in an anhydrous organic polar solvent (e.g. N,N-dimethylacetamide) in an anhydrous inert gas atmosphere at 50-200 deg.C for about 1-20hr while removing the by-product (carbon dioxide gas) from the system.

Title: Charged particle optical system
Inventor: KURODA KATSUHIRO
IPC: H01J37/248
Filed: 1988-05-11
Abstract: PURPOSE:To make it unnecessary to provide a specific space by providing a throttle with an opening smaller than the width of charged particles focused at the focus position of a lens other than a lens immediately in front of the sample. CONSTITUTION:A throttle 3 for energy filtering is arranged at the focus point of a capacitor lens 12. Therefore, the width of electron beams 2 is restricted by the throttle 3, and the electron beams with the energy width smaller than that released from an electron gun 1 are injected to an object lens 13. As a result, the color aberration of the object lens is reduced, and the resolution ability is improved. Consequently, a filter to reduce the energy width can be composed in a structure simpler than the conventional one, and a charged particle optical system with the space smaller than that of the conventional one can be obtained.

Title: Preparation of tin plated steel plate for welded can
Inventor: KANBARA SHIGEO
IPC: C25D5/10
Filed: 1982-07-01
Abstract: PURPOSE:To prepare a tin plated steel plate for a welded can excellent in paint close-adhesiveness and corrosion resistance and low in cost, by a method wherein a tin plated steel strip is subjected to cathodic electrolysis in an aqueous sodium bicarbonate solution and a metal Cr film and a Cr oxide film are subsequently formed by cathodic electrolysis. CONSTITUTION:Tin plating is applied to a steel strip so as to adjust the amount of tin to a relatively small amount of 0.55-1.65g/m<2> per one surface thereof and subjected to cathodic electrolysis within a range of about 0.5-5 coulomb/ dm<2> in an aqueous sodium bicarbonate solution to activate the surface of the tin plated steel strip. In the next step, thin tin plated steel strip is further subjected to cathodic electrolysis in a two-component system CrO3 aqueous solution containing 5-30g/l CrO3 and 0.5-2.0g/l NH4F to form a chromate film comprising 5-30mg/m<2> metal Cr and 5-20mg/m<2> Cr oxide (on the basis of a CR amount) on tin plating. By this method, a tin plated steel plate suitable for the preparation of a high speed resistance welding can having stable corrosion resistance and paint close-adhesiveness is obtained in a reduced tin plating amount.

Title: Recovery system for runaway of microcomputer
Inventor: KOMODA YOSHIYUKI
IPC: G06F11/00
Filed: 1985-05-25
Abstract: PURPOSE:To recover the runaway of a microcomputer by detecting an overflow state of a stack area with an 8-bit processor of 68 systems. CONSTITUTION:A RAM 3 containing a stack area uses addresses 0h-1FFFh and a memory 4 to which a program is written uses addresses 8000h-FFFFh respectively. Under such conditions, the addresses after 1FF6h form a stack area 1 and a reserved area 2 contains addresses 1FF7h-1FFFh. The EEh is written to each address of the area 2. If a return instruction RST given from a subroutine is executed excessively due to a runaway, the value written to the area 2 is read into a program counter and therefore the program counter shows the EEEEh. Then the control is shifted to the EEEEh. Thus the runaway can be recovered by writing previously a runaway recovery routine or a jump instruction to the runaway recovery routine from the address EEEEh.

Abstract: PURPOSE: To control wheel speed to maintain an instantaneous value of a coefficient of friction of road surface μ close to the maximum value by calculating the value by an equation of motion which is based on electric signals each of which corresponds to wheel speed acceleration and deceleration, a brake torque, and a wheel  weighting.  
     CONSTITUTION: A signal to judge increase or decrease of an output signal of coefficient of friction of road surface μ by discriminating whether a differential value is positive or negative by differentiating μ of coefficient of friction of the road surface detecting device 5 at a coefficient of friction increase or decrease discriminating part 6. At an actuator control part, responding to a μ reduction discriminating signal, a reduction in brake hydraulic pressure is instructed when the brake hydraulic pressure has been increased, and an actuator control signal is generated to increase when the pressure has been reducing. Being thus constituted, wheel speed is controlled to maintain the coefficient of friction of road surface μ close to the maximum value. When the same control signal keeps on being generated for longer than a set period of time and μ signal wouldn't change in the direction of increase, a timer part 9 switches control signal to the control part 7.

Abstract: PURPOSE:To prevent contact between a wheel cover and a seal fin by making the wheel cover of wheel group containing a stopper wheel to be stopped to a turbine rotor disc thinner than the wheel cover of other wheel group. CONSTITUTION:In the wheel group to be stopped to the outercircumference of a turbine rotor disc 1, the wheel cover 13a in the wheel group containing a stopper wheel 7 is made thinner than the wheel cover 13b in other wheel group.
