Title: Manufacture of vinyl chloride resin
Inventor: KOBAYASHI SADAHITO
IPC: C08F2/18
Filed: 1988-08-19
Abstract: PURPOSE:To suppress foaming of a polymerization suspension thereby preventing it from overflowing, and further to make is possible to produce a product which has no fish eyes by using a polymerizer equipped with a reflux condenser to introduce previously a non-condensable gas into the polymerization system when a vinyl chloride resin is subjected to suspension polymerization. CONSTITUTION:When vinyl chloride monomer or a mixture of vinyl chloride monomer with other monomer polymerizable therewith is subjected to suspension polymerization using a polymerizer equipped with a reflux condenser in the gas phase part of the polymerizer or outside the polymerizer, a non-condensable gas is previously introduced into the polymerization system (N2 gas is preferred from the point of view of the cost, the influence on the quality of the product, and the like), then the polymerization is started, and the non-condensable gas is purged from the polymerization system. According to the process, the feed of polymerization can be increased without causing overflow of the polymerization suspension into a conduit connecting the polymerizer with the reflux condenser and into the reflux condenser, formation of scale in the conduit and the reflux condenser is prevented, and a product which is excellent in quality and does not have fish eyes or the like can be produced.

Title: Rolling bearing device
Inventor: MURAKI HIROMITSU
IPC: F16C25/08
Filed: 1998-07-23
Abstract: PROBLEM TO BE SOLVED: To control a swing arm at higher speed with higher precision by setting the linear expansion coefficient of an inner ring larger than the linear expansion coefficients of a rolling body and an outer ring, and/or setting the linear expansion coefficient of a shaft larger than the linear expansion coefficient of a housing, and using oil as lubricant. SOLUTION: The linear expansion coefficient of an inner ring 1 is set larger than the linear expansion coefficients of a ball 5 and an outer ring 2, and/or the linear expansion coefficient of a shaft 2 is set larger than the linear expansion coefficient of a housing 4. Further, as the lubricant of a ball bearing 6, oil 8 is used. Since the oil 8 is apt to get into a moving contact surface and dispersible of heat, the initial scattering of the lubricant can be minimized. The deterioration of the ball bearing 8 in operation is also minimized to minimize the torque fluctuation of a bearing device. Since the linear expansion coefficients of the inner ring 1 and the shaft 3 are larger than those of the outer ring 2 and the housing 4, the bearing clearance is never increased at a high temperature, so that the reduction in resonance frequency by preload release can be prevented, and satisfactory positioning performance can be provided.

Title: Illumination emission system
Inventor: TOUHOU MAKOTO
IPC: H01J61/24
Filed: 1981-12-21
Abstract: PURPOSE:To increase the luminous efficiency of an illumination emission system by using the second airtight space as a space containing a gas which is excited to a high level by directly absorbing emissional radiations discharged from the first airtight space, and can be shifted to a ground level while radiating emissions having gradually increasing wave lengths. CONSTITUTION:The first airtight space 1 forms a low-pressure mercury electric-discharge tube 4. The second airtight space 2 is formed between the tube 4 and a cylindrical outer tube 5 which is provided outside the tube 4 coaxially with the tube 4, and  charged with a gas principally consisting of sodium vapor. When low-pressure mercury electric-discharge is carried out in the first space 1, a radiation principally consisting of a wavelength of 2.54nm is transmitted to the second space 2, and sodium atoms are excited to a high level by absorbing ultraviolet rays. When all reverse-excitations are supposed to be performed by radiation transition to a given level, D-rays and emissions of around 480nm cover about 4/7 of the whole input, and a little under 60% of the ultraviolet input is converted into two kinds of spectra (590nm and 480nm) which are desirable for directly emitting white light. Besides, since the ratio of the former spectrum to the latter spectrum is 5 to 3, the outputs of the spectra are mixed into an almost white color.

Title: Heat storage heater
Inventor: AKIYAMA YOSHIO
IPC: F24H7/02
Filed: 1994-08-31
Abstract: PURPOSE: To provide a heat storage heater which achieves a preventing of hot air of a heat storage body from blowing at a blowing port as contained in an air path at the start of operation. CONSTITUTION: When a heat storage body 2 is above a set temperature, a heat storage body air path 12 is opened with a shutter 27 and a sirocco fan 45 is driven to rotate with a blowing motor 46 in an intense operation so that air is sent through the heat storage body air path 12 from the sirocco fan 45. As air contacts a radiation fin 6 of the heat storage body 2, the temperature of the air flowing through the heat storage body air path 12 rises. A lower exothermic heater 23 alone is turned ON, the air from the sirocco fan 45 is shunted with the shutter 27 to be heated with the heat storage body 2 in the heat storage body air path 12 and heated with the lower exothermic heater 23 in a heater air path 24. Immediately after the starting of the operation, hot heat is contained in the heat storage body air path 12 while the lower exothermic heater 23 does not raise heat.  This allows the mixing of the air with a mixing chamber 33 to blow at the blowing port 31 thereby keeping hot air from blowing at the blowing port 31 beyond the necessity thereof.

When the printing head reaches the home position, a signal (d) is sent to the logic circuit 70, the output of the logic circuit 70 is stopped, and the prohibition of printing is released. At the same time, the output stoppage of the logic circuit 70 is detected by a breaking detector 90, a reset signal (g) is sent out, and the counter 40 is reset. Again, line feeding and printing are continued and the foregoing retracting operation is repeated.
