Title: Traffic signal checker
Inventor: AMAHISA SAWAKO
IPC: G08G1/0962
Filed: 1993-02-22
Abstract: PURPOSE:To prevent an accident and reduce traffic congestion at an intersection by making a traffic signal checker synchronously illuminate a lamp when conditions where it is difficult to discriminate the color of a traffic light are generated during a travel of a vehicle on a road. CONSTITUTION:Lamps of three colors are arrayed laterally on the upper part of the dashboard and on the left side in the cabin 1 of a four-wheeled vehicle and when this vehicle travels straight as shown by an arrow mark and approaches a traffic signal light 2 provided on a road 3, the lamp of the same color as the traffic light illuminates. Namely, this checker has a mechanism which receivers a signal sent from the traffic signal light 2 provided on the road 3 and turns ON the lamps of the three colors. The range of the capability of reception are different by road conditions such as speed setting on the road and the intervals of traffic signal light 2, but are determined according to the transmission level of the signal light 2 on the road. Consequently, a traffic accident in an uneasy state when a driver enters the intersection without making sufficient confirmation or passes through the intersection in a hurry at the time of yellow illumination can be prevented.

Title: Time division driving apparatus
Inventor: HISATOMI SHINICHI
IPC: B41J2/21
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To increase a life of a battery by reducing as much as possible a maximum current to division drive printing elements while maintaining a printing quality. SOLUTION: When a temperature of a printing head rises and a printing efficiency is improved, a power is made constant and driving pulses are applied with an application time shortened. For example, in concurrently driving printing heads set by color and driven in one cycle Ts of a fundamental waveform, concurrent driving of three colors of K, C and M, and Y, (c) and (m) at the driving time by the fundamental waveform is switched to concurrent driving of two colors of K and C, M and Y and, (c) and (m) when the driving pulse has not larger than 33% a duty of the fundamental waveform and to individual driving for each color when the duty is not larger than 16.6%.  A maximum current value I3 of a current waveform of the entire printing head at each time is reduced respectively to not lager than 2/3 and not larger than 1/6 a maximum current value of a current waveform when the number of concurrent driving is not changed. A battery life is prolonged because the maximum current value is reduced.

Title: Method for mounting protective plate for liquid crystal display surface
Inventor: MORIMOTO YUKIHIKO
IPC: G02F1/1333
Filed: 1987-03-30
Abstract: PURPOSE:To permit easy attachment and detachment of a protective late and sure fixing thereof by once curving the protective plate, fitting the plate into a recess and supporting the plate in detaining holes at both ends and the central part of the plate part, thereby stably holding the protective plate to the liquid crystal display surface of a housing. CONSTITUTION:To amount the protective plate 12 into the recess 16 of the device housing 13, an operator inserts one end of a projecting part 12a into the detaining hole 17 of the device housing and pushes the central part upward to warp the downward projecting protective plate to an upward projecting state while holding the end on the side opposite from the inserted end. The remaining part of the projection 12 is inserted into the detaining hole 17 on the housing side when the projection 12a at the opposite side end is inserted into the recess and the central part lifted by the operator is released in this state. The protective plate 12 has the downward projecting shape in a free state and, therefore, the force is acted on the protective plate in the detained state by a frame-shaped plane 15 and the detaining hole 17 in the direction where the downward projecting warpage is returned. The display surface is thus built without clattering and lifting. The protective plate is easily removable by hooking the fingertip in a central notch 18 or lifting the same by a puller.
