IPC: B41J29/377
Filed: 1990-11-28
Abstract: PURPOSE:To protect a heat generating element of a recording head against runaway of a CPU by comparing to decide whether a conducting time exceeds a maximum time or not, judging occurrence of a malfunction when a decided result is yes, and stopping conducting means. CONSTITUTION:A heat error timer 17 starts counting when the output HEATEN of a NOR circuit 13 is 'H', i.e., when a head driver is ON. When a level of a TOUT signal is not varied due to occurrence of the malfunction and a level 'H' holding state of the signal HEATEN is elapsed for a predetermined time or longer, an overflow signal TOV is output from the timer 17, and latched to a D type latch circuit. Since the output of the latch circuit is connected to the other input of the NOR circuit, when the timer 17 overflows, the output of the latch circuit becomes 'H', the output HEATEN of the NOR circuit is shifted from 'H' to 'L', and heat of a heat driver 5 is automatically (forcibly) turned OFF.

Title: Combustion apparatus for heating refrigerant
Inventor: ARAI YASUHIRO
IPC: F23N3/08
Filed: 1990-11-28
Abstract: PURPOSE:To always keep the combustion of the above apparatus in a good condition even if the temperature of the outside air changes, by a method wherein when the temperature of the outside air is at a specified value or higher, an air-flow by an air supply fan is increased and when the temperature of the outside air is under the specified value, the air-flow is decreased. CONSTITUTION:When a cooling and heating apparatus begins to be operated, the flames of a burner 57 are formed simultaneously with the start of a compressor 1 and its combustion heat heats a refrigerant flowing in a heat-exchanger 49 by heat-exchange. In this case, the amount of combustion previously determined by a fuel-feeding device 55 matchs with the rotation speed of an air supply fan 53 for the combustion, and the combustion is kept in a good condition. When the temperature of the outside air is low and the density of the air is high, an air-flow is decreased by decreasing the rotation speed of the air supply fan 53, so that the air-flow is kept from an excessive supply and the flames are prevented from blow-off. On the other hand, when the temperature of the outside air is high and the density of the air is low, the air-flow is increased by increasing the rotation speed of the air supply fan 53, so that the air-flow is kept from a short supply and incomplete combustion is prevented. For that reason, even if the temperature of the outside air changes, the ratio of air to fuel is always kept constant and the combustion can be kept clean and is always kept in the good condition.

Title: Back-light device and color display device
Inventor: ASAKAWA SHIRO
IPC: B60Q3/04
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To provide a back-light device for various display devices excellent in light utilization efficiency by providing a high-refraction factor layer on the light outgoing face of a light guide body, and providing a scattering layer on it. SOLUTION: The light passing through a color filter 503 passes through a high-refraction factor layer 506, and it is scattered by a light scattering layer 505 to form an image. Since a low-refraction factor layer 511 exists between a light scattering layer 508 and a light guide plate 507, the light fed to the light guide plate 507 is totally reflected on the boundary face of the low- refraction factor layer 511, and the light does not enter the light scattering layer 508. The light passing through the transparent section of the light scattering layer 505 is totally reflected by the low-refraction factor air layer on the outside, and no direct light is leaked to the outside. The light guided to the light guide plate 507 through the color filter 503 is used only for the scattering on the light scattering layer 505.  The light fed to a light guide plate 510 through a color filter 504 is guided to the light scattering layer 508 through a high- refraction factor layer 509 to form an image according to a pattern set in advance, and the light is projected to the outside.

Abstract: PROBLEM TO BE SOLVED: To metallize a transmissive anode emitter with no trouble by specifying the thickness of the anode emitter and the doping concentration thereby setting the emitter efficiency of the anode emitter at a required level through setting of the lifetime of local carriers.

For that purpose, nucleus of proton or helium is preferably irradiated at a depth deeper than the intrusion depth of the anode emitter 2 but shallower than the intrusion depth of a stop layer 3.
