Title: Emergency lighting device
Inventor: SHIRAO AKITOSHI
IPC: H05B41/14
Filed: 1994-06-28
Abstract: PURPOSE:To provide an emergency lighting device capable of simplifying a circuit configuration. CONSTITUTION:When a commercial AC power supply E is operating, electric current flows to a relay coil RyL11, thereby closing a relay contact RyS11a and opening other relay contacts RyS11b and RyS11c. The voltage of the power supply E is full-wave rectified with a full-wave rectifier 12 and, then, smoothed with a smoothing circuit 13. Then, the voltage is made to resonate through the primary winding Tr12a of the inverter transformer Tr12 of the first inverter circuit 14 and a capacitor 15, and converted to high-frequency AC to induce high-frequency AC across the secondary winding Tr12c of the transformer Tr12, thereby turning on a fluorescent lamp FL. When the power supply E is interrupted, no current flows to the coil RyL11. Thus, the contact RyS11a is opened, while the contacts RyS11b and RyS11c are closed. Also, the voltage of a battery B is made to resonate through the primary winding Tr12b of the inverter transformer Tr12 of the circuit 14 and a capacitor C17, and converted to high-frequency AC, thereby turning on the fluorescent lamp FL.

Filed: 1989-06-12
Abstract: PURPOSE:To easily make operation correspondent even when a communication system is changed by providing a function part for the various kinds of setting, signal velocity selecting circuit, interface selecting circuit and DTE/DCE switching circuit. CONSTITUTION:Since the various kinds of signal velocity from low velocity to high velocity is outputted by a various signal velocity generating circuit 14 for setting the signal velocity, according to the instruction of a setting part 16, a signal velocity selecting circuit 15 applies the designated signal velocity to a parallel/serial converting circuit 6 for common line, imbalanced transmission circuit 8 and balanced transmission circuit 11. For setting an interface circuit, an instruction is applied form the setting part 16 to an interface selecting circuit 7, either the imbalanced transmission circuit 8 or balanced transmission circuit 11 is selected. For setting DTE/DCE, an instruction is applied from the setting part 16 to DTE/DCE switching circuits 9 and 12 and either the DTE or DCE is set. Thus, when a common signal system is constructed, the operation can be easily made correspondent.

Title: Subordinate synchronizing system
Inventor: KATSUTA CHIKAHIDE
IPC: H04L7/00
Filed: 1989-06-12
Abstract: PURPOSE:To decrease the number of links in a network synchronizing device by distributing a reference frequency by using a virtual container(VC) which is the constituting element of a network node interface(NNI) frame. CONSTITUTION:The frequency component of a VC-32 pass inserted from the network synchronizing device with VC processing function in an A station, which is equipped with function to reproduce the reference frequency, is velocity- converted to an STM-1 frame of the NNI and sent by a VC-STM frame converter 17. In the AU-32 destuff device 18-F of a synchronizing multiple converter 16-F in a final station F, the AU 32 including the VC-32, which is inserted by the converter 17, is picked up from this STM-1 frame. A P/N stuff, which is inserted in passing stations B-E, is destuffed and the same frequency component as the frequency component, which is generated by the network synchronizing device 19-A with VC processing function in the A station, can be received by a network synchronizing device 19-F with VC processing function in the F station. Thus, the number of the links in the network synchronizing device can be prevented from being increased.

Title: Variable wavelength light source apparatus
Inventor: ODACHIME HIROAKI
IPC: H01S3/1055
Filed: 1994-06-06
Abstract: PURPOSE:To vary the oscillation frequency of an external resonance type variable wavelength light source apparatus using a semiconductor laser (LD) while a same external resonator longitudinal mode is maintained by a method wherein a current injected into the phase adjustment region of the LD and the rotation angle of a deflection lattice are simultaneously varied. CONSTITUTION:A light emitted from the AR-coated end surface of an LD 6 having a phase adjustment region 6b is converted into a collateral beam by a lens 2 and enters a deflection lattice 3. Only light components which are selected by spectral dispersion and have specific wavelengths are reflected by the deflection lattice 3 and returned to the LD 6. With this constitution, an external resonator (effective resonance length: K) is formed between the LD 6 and the deflection lattice 3 and a laser oscillation having a wavelength which is determined by the external resonator longitudinal mode and the resonance loss is created. The effective resonance length K is varied by a current injected into the phase adjustment region 6b. A current injection means 7 injects a current into the phase adjusting region 6b and an oscillation wavelength control means 8 controls the injected current supplied by the current injection means 7 and the rotation angle of the deflection lattice 3.

Title: Formation of white surface
Inventor: HOSOKAWA MINORU
IPC: C23C14/04
Filed: 1980-10-23
Abstract: PURPOSE:To control the surface shape of a reflection plte so as to obtain the best whiteness or brightness by vapor depositing metal through a vapor deposition mask which is fixed in such a way that the end part of a window for vapor deposition does not adhere to the substrate surface to be deposited. CONSTITUTION:In forming a white substrate for display by liquid crystals or the like a patterned mask 71 is fixed on a substrate 73 to be subjected to surface whitening treatment by taking a constant spacing L with respect to said substrate 73.

Title: Heating roll type fixation device
Inventor: SUZUKI YOSHIYASU
IPC: G03G15/20
Filed: 1982-08-28
Abstract: PURPOSE:To eliminate the pressure distribution owing to the bending deformation of both heating and pressurizing rolls by supporting pivotally an auxiliary roll slightly across the axis of the heating roll so as to contact with the central part of the heating roll. CONSTITUTION:When the transfer paper is passed between the heating roll 1 and the pressurizing roll 2, a toner image is fixed. The force by which the central part 1b of the roll 1 is brought into press contact with the central part 2b of the roll 2 is exerted to the central part 1b of the roll 1 by the central part 5b of an auxiliary press contact roll 5 made of metal, and therefore even if the bending moment to part the central parts 1b, 2b of both rolls from each other is applied on said parts by the press grasping reaction of the transfer paper, said bending moment is born by the roll 5 and the contact pressure P between the roll 1 and the roll 2 is uniformly distributed. A toner image is thus uniformly fixed on the transfer paper and the fixation failure and the generation of crease are prevented.
