Title: Serial signal modulation device
Inventor: FUCHIGAMI HIROYUKI
IPC: H04L27/12
Filed: 1989-10-20
Abstract: PURPOSE:To obtain a serial signal modulation device which can execute modulation on +/- sides by providing two diodes and two resistances between a serial signal source and an FM modulator. CONSTITUTION:IC 1 is the FM (frequency) modulator and a micro computer IC2 from which a signal passes through the resistance R1, the diode D1, the resistance R2 and the diode D2 to a common input terminal 5 is a serial signal source. Consequently, a serial signal from an output terminal 3 changes L H, the modulation output of the FM modulator IC1 is displaced to the '+' side. When the serial signal from an output terminal 4 changes H L, the modulation output is displaced to the '-' side. Thus, the FM modulator IC1 can be modulated to both +/- sides by transmitting the serial signal from the micro computer IC2 at the timing of the serial signals B and C.

Title: Combined safety and pressure filling valve, safety method for use thereof and method for pressure filling thereof
Inventor: KITABAYASHI SEIICHI
IPC: B05B9/04
Filed: 1994-10-03
Abstract: PURPOSE: To prevent the explosion of a container by providing a lower packing between the outer peripheral part of the lower end of a valve stem and the inner peripheral part of the lower end of a valve housing and a spring acting to downwardly bias the lower packing to the closing position, whereby, when the inner pressure of the container is made high by heat, pressured gas is discharged from a flow passage. CONSTITUTION: At the time of pressure filling, a pressure filling valve mechanism is made capable of performing the pressure filling of a container from its pressure filling passage and, when the inner pressure becomes high upon receiving heat, a lower packing 4 interposed between the outer peripheral part of the lower end of a valve stem 6 and the inner peripheral part of the lower end of a valve housing 2 is made to rise deflecting a spring 5 acting to downwardly bias the lower packing to the closing position to open a flow passage for discharging the inner pressured fluid in order to discharge the pressured gas therefrom, thereby preventing the explosion of the container.  Therefore, even if the container becomes high in inner pressure in incinerators, etc., upon receiving combustion heat therein, the pressured gas is discharged from the inside of the container to prevent its explosion.

Title: Capsule toner for heat roller fixing
Inventor: MATSUBARA AKITOSHI
IPC: G03G9/093
Filed: 1986-11-19
Abstract: PURPOSE:To obtain excellent low-temp. fixability and offset resistance and to expand a practicable fixable temp. range by incorporating a nonlinear polymer and wax into meltable core material particles. CONSTITUTION:This capsule toner has the meltable core material particles and the shells consisting of a thermoplastic resin so provided as to coat the surface of the core material particles. The nonlinear polymer and the wax are incorporated into said meltable core material particles. Since the nonlinear polymer has crosslinked structure of network structure, the viscoelasticity of the toner when melted is adjusted to an adequate size and the transfer of the toner material to a heat roller of a heat roller fixing device is hardly generated. The offset resistance is thus obtd. The toner is made meltable at the lower temp. by the characteristic of the wax that the wax melts efficiently at a low temp. The excellent low temp. fixability is exhibited particularly under environmental conditions of a low temp. and low humidity. The fixable temp. range is thereby greatly expanded.

Title: Ignition device
Inventor: IWABORI MASAYUKI
IPC: F23Q2/16
Filed: 1994-10-13
Abstract: PURPOSE: To enhance ignition efficiency by moving a movable member at a stroke by an elastic force of a pressure-stored drive elastic member in the forced direction and turning a ratchet and a rotary ignition means. CONSTITUTION: A slide member 51 is engaged with a movable member 45 until a forcing operation member 41 is forced in by a definite quantity while a drive elastic member 49 stores its elastic pressure between the forcing operation member 41 and the movable member 41. When the forcing operation member 41 is forced in beyond the definite quantity, them forcing operation member 41 pushes back the slide member 51 against the elastic force of the elastic member 49, thereby releasing the engagement between the slide member 51 and the movable member 45. Therefore, the movable member 45 moves in the forced direction at a stoke by the elastic force of the pressure-stored elastic member 49, thereby turning a rotary member 13 and engaging a locking claw 17 with ratchet teeth 18 of a ratchet 12 and then turning the ratchet 12 and a rotary ignition means.  This construction makes it possible to enhance ignition efficiency by rubbing an ignition stone to ignite.
