Title: Recovery of epsilon-caprolactam from lactam solution containing epsilon-caprolactam oligomer
Inventor: FUJIWARA KATSUAKI
IPC: C07D201/16
Filed: 1980-07-17
Abstract: PURPOSE: In recovering ε-caprolactam from a lactam solution containing ε-caprolactam oligomer, to improve the purity and yield of ε-caprolactam, by adding caustic alkali in rectification process without adding the caustic alkali in distillation process.  
     CONSTITUTION: A lactam solution containing ε-caprolactam oligomer is distilled without adding caustic alkali to it, and the solution is separated into a distillation residue consisting essentially of the oligomer and ε-caprolactam. The residue is depolymerized in the presence of phosphoric acid and overheated steam, so that ε- caprolactam is recovered in the form of an aqueous solution. 0.01W0.5pts.wt. caustic alkali (e.g., NaOH, KOH, etc.) based on 100pts.wt. solution obtained in the distillation process is added to ε-caprolactam prepared in the process, and it is rectified to give ε-caprolactam.

Title: Production of optical fiber having gas-tight coating
Inventor: KORUNERISU MARINUSU HERITSUTO
IPC: C03C25/106
Filed: 1990-04-16
Abstract: PURPOSE: To coat an optical fiber at a higher speed particularly by a decomposition reaction and to hold furnace walls clean by bringing this fiber into contact with carbon-contg. gas in a position where the optical fiber exists in a prescribed high temp. range and regulating the wall temp. of a reactor to a specific value or below.  
     CONSTITUTION: After the optical fiber 10 is formed by drawing a preform 12, the optical fiber is immediately brought into contact with the carbon-contg. gas, for example, butane-contg. gaseous Ar, in the carbon deposition reactor at a high temp. As a result, the optical fiber 10 having the hermetic coating of an amorphous carbon type is obtd. In such a case, the optical fiber 10 is brought into contact with the carbon-contg. gas described above and the wall temp. of the reactor 16 is kept at ≤800°C in the position where the temp. of the optical fiber 10 in the reactor 16 is between 1100 and 1500°C. The carbon- contg. gas is required to be incorporated with an inert carrier gas having a coefft. of thermal conductivity smaller than 0.04J/m.s. at 27°C. As a result, the carbon layer of such a type which suppresses the diffusion of hydrogen into the glass fiber is formed.

IPC: F16H7/02
Filed: 1982-06-07
Abstract: PURPOSE:To obtain an excellent anti-rolling characteristic, by spanning a belt in crossing between a pulley and a flywheel provided to a rotating shaft of a motor, tilting the motor and adjusting the crossing position of the belt. CONSTITUTION:The belt 16 is spanned in the shape off the figure 8 in crossing between the pulley 12 and the flywheel 13 provided with the rotary shaft 11 of the motor 10, and the motor 10 is tilted by a required minimum value to prevent the belt 16 from being contacted at the cross point of the belt 16. Thus, it is required to increase the distance X1 from the cross point to the center of the flywheel 13 viewed from the side more than that X2 viewed from the top, and it can be satisfied by selecting the inclination between the flywheel 13 and the pulley 12. Thus, the direction of rotation between the motor 10 and the flywheel 13 is reversed each other, then a rolling force is cancelled if existing, and since no separate flywheel is required, the device is miniaturized and made inexpensive.

Abstract: PURPOSE:To eliminate the necessity of power consumption in holding contacts in a conducting or nonconducting state, electrically control switching of the contacts and make the structure of a toggle switch small by providing a fixed portion having a fixed contact and a fixed electrode, and a moving portion having a movable contact and a movable electrode. CONSTITUTION:A toggle switch, which holds a fixed contact 20 and a movable contact 50 in a conducting or nonconducting state by means of a spring, is provided with a fixed portion 10 having the contact 20 and a fixed electrode 30 and a movable portion having the contact 50 and a movable electrode 60. When a potential difference is applied between the electrodes 30, 60 from outside the toggle switch, electrostatic forces are generated between the electrodes 30, 60 and the movable portion 40 moves against the spring, switching the conducting state to the nonconducting state or vice versa. Thereby switching of the contacts can be controlled electrically, and application of the potential difference between the electrodes 30, 60 is required only at the switching of the contacts, so power consumption is not required in holding the contacts in the conducting or nonducting state, and the need for a coil for an electromagnet is eliminated, whereby the whole structure can be made smaller.

Title: Measuring instrument for electrostatic charging quantity of toner
Inventor: OYAMA KATSUMI
IPC: G03G9/087
Filed: 1987-04-22
Abstract: PURPOSE:To accurately measure an electrostatic charging quantity distribution by forming the right-angled section of an intake pipe flat in a toner falling direction and opposing electrode plates to each other so that an electric field is produced nearly at right angles to the lengthwise direction of the exit of the intake pipe. CONSTITUTION:A housing 1 consists of a separation part 2 which separates toner from a developer and a measurement part 2 which measures the electrostatic charging quantity distribution of the separated toner. Then the measurement part 3 is equipped with a couple of electrode plates 9a and 9b, which face each other so as to produce the horizontal parallel electric field by the application of a DC power source B at right angles to the lengthwise direction of the exit 6b of a funnel 6. Consequently, the deflection quantity of toner when it passes through the electric field varies in the lengthwise direction of the exit 6b of the funnel 6, and consequently the spread of its falling position varies, thereby calculating the invariably accurate toner electrostatic charging quantity even if the deflection quantity varies large owing to variance in the electrostatic charging quantity of toner particles.
