Title: Light guiding plate and surface light source device and display device using that light guiding plate
Inventor: MABUCHI KOJI
IPC: G02B6/00
Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To provide a light guiding plate which can show uniform luminance without irregularity even when light is introduced through two side end faces facing each other, and to provide a surface light source device and a display device using this light guiding plate and capable of obtaining excellent performance evaluation. SOLUTION: A first diffusing means and a second diffusing means are formed on the back face 14 of a light guiding plate 1. The first diffusing means consists of plural recesses 15 each formed in such a manner that the projected area of the recess on a light-emitting face 13 differs according to the distance from a first light- entering face 11 and that each recess has a slope 15a facing to the light-emitting face 13. The second diffusing means consists of plural recesses 16 each formed in such a manner that the projected area on the light-emitting face 13 differs according to the distance from a second light-entering face 12 and that each recess has a slope 16a facing to the light-emitting face 13. The slope 15a of the recess 15 is formed in the first light-entering face 11 side, while the slope 16a of the recess 16 is formed in the second light-entering face 12 side.  Thereby, the light outgoing from the emitting face 13 shows uniform luminance.

Title: Control circuit for oil burner
Inventor: HORIUCHI TOSHIHIRO
IPC: F23N5/02
Filed: 1990-01-24
Abstract: PURPOSE:To prevent the abnormal increase of the temperature of a gasifying part by providing a delay timer to delay judgment of disconnection of a temperature sensor by a specified time starting from the starting of energization of a heater for gasification and a compulsion timer to forcedly stop re-energization of the heater for gasification for a specified time. CONSTITUTION:During disconnection of a gasifying part thermistor 5, energization to a heater 4 and counting of a disconnection judgment timer 13 are started by turning ON an operation switch 9. Since the temperature of a gasifying part is increased and the gasifying part thermistor 5 is in a disconnecting state, a resistance value is kept at a high value. When the disconnection judgment timer 13 is completed, a disconnection detecting circuit 14 is driven, temperature data of the gasifying part thermistor 5 is inputted from a thermistor circuit 12, it is judged that temperature is below a disconnection judgment temperature, and a compulsion timer 15 is driven. During this time, a heater 4 is turned OFF. A forced blast circuit 16 is driven, a blast motor 7 is started to run, and the temperature of the gasifying part is reduced. Further, even when return operation of abnormality is performed, the return operation is rendered ineffective while the forced timer 15 is worked, forced blast is continued, and the temperature of a gasifying part 3 is prevented from an abnormal increase.

Title: Anode short-type gto thyristor
Inventor: HASHIMOTO OSAMU
IPC: H01L29/74
Filed: 1994-02-08
Abstract: PURPOSE:To reduce gate impedance by a method wherein a region which is directly under a cathode electrode and in which a heavily doped p-type impurity layer does not exist is made narrow up to the diffusion length of carriers. CONSTITUTION:A heavily doped p-type impurity layer 10 whose impurity concentration is much higher than that of a heavily doped p-base layer 3 is diffused to the surface of the heavily doped p-base layer 3. Then, a lightly doped p-base layer 4 is formed on the surface of the heavily doped p-base layer 3 and the heavily doped p-type impurity layer 10, and, in addition, an n-type emitter layer 5 is formed on its surface layer. Directly under a cathode electrode 8, the heavily doped p-type impurity layer 10 is not formed in a region 11 whose shape is similar to the n-type emitter layer 5 or the cathode electrode 8 and whose width is 50 to 100mum. Thereby, carriers which are near the heavily doped surface layer of the p-base layer 3 and whose diffusion length is 50 to 100mum can reach the heavily doped p-type impurity layer 10 easily from the center of the region 11. As a result, the gate impedance is reduced.

IPC: G02B6/44
Filed: 1982-01-30
Abstract: PURPOSE:To permit tape-winding onto a cable with a constant low tension by controlling a tape drawing-out speed by means of the electric signal generated from a displacement detector which detects the displacement of a tape tension controlling mechanism. CONSTITUTION:A main motor 25 is controlled by a controller 88, and the revolution number signal of said motor 25 is transmitted to a linear actuator controller 90, from which the signal programmed beforehand is sent into an actuator 84, and the appropriate feedback signal is returned into the controller 90 through a potentiometer 86. A tape drawing-out speed depends upon the displacement of  a control arm 36 and does not depend upon the tension of the tape. Further, even if the tape drawing-out speed varies to any extent, the tension of the tape  is not varied, and the tape is strictly controlled by a tension controller 65.

Filed: 1987-01-23
Abstract: PURPOSE:To make one mask for pattern formation unnecessary and to easily pattern a fuse by a method wherein a barrier metal for pattern formation of a wiring metal and the fuse for connection of wiring metal are coated with titanium nitride (TiN) simultaneously. CONSTITUTION:When a wiring metal is to be formed by diffusion, a barrier layer, which is used to prevent this metal from being diffused into a semiconductor, and a fuse are coated with titanium nitride during an identical process; after that, the wiring metal is formed by diffusion. The material for the fuse is titanium nitride (TiN), and this material can be formed easily by a reactive sputtering process of Ti where nitrogen gas (N2) is introduced into an atmosphere of argon gas (Ar). The wiring metal 1 is formed by diffusion by using a barrier metal which is patterned and formed simultaneously with the fuse 2. Because the fuse is patterned simultaneously with the barrier metal for pattern formation of the wiring metal, it is possible to make one mask for pattern formation unnecessary as compared with the case where an NiCr fuse or a PtSi fuse is used.

Abstract: PURPOSE:To lower the average power loss at start of a motor and increase the average current at regularity by using a linear control method where noise is little or a PWM control method where power loss is little while changing them over to each other. CONSTITUTION:A linear-PWM changeover circuit 12 changes switches SW1 and SW2 over to each other by an at-start/at-steady operation changeover signal S2. At start of a three-phase motor 6, a large current is required, and noise does not matter, so the PWM control is selected. And in the PWM control, the switch SW1 is connected to the output of a comparator 11, and the switch SW2 is connected to a motor driving power source V. Next, the control signal supplied to the transistor on the ground side of an output stage driving circuit 5 is gotten by modulating it into a PWM signal through an AND circuit 3 and a predriver circuit 4 by the signal which is made by comparing the voltage level of the output of an operating amplifier 9 with that of a triangular wave generating circuit 10 with a comparator 10. By this PWM signal, the rotational speed of the motor 6 can be maintained constant.

Filed: 1982-02-02
Abstract: PURPOSE:To prevent the same call from being rejected for a long time, by changing a call signal selecting system successively in case of selection of call signals so that a higher-level call signal is selected in a high probability. CONSTITUTION:Call signals consist of, for example, two groups of 20 waves, and one wave of the upper group and one wave of the lower group, namely, total two waves are transmitted in parallel in respect to one call signal. In case of selection of these call signals, one wave is selected from upper groups 40-00 and is selected from lower groups 4-0 in 16 waves of upper and lower groups in the first time, and one wave is selected from upper groups 60-20 and is selected from lower groups 6-2 in the second time, and one wave is selected from upper groups 80-40 and is selected from lower groups 8-4 in the third time, and one wave is selected from upper groups 90-50 and is selected from lower groups 9-5 in the fourth time. Thus, each time when the same call is rejected, the probability of selecting it is higher surely, and the possibility of acquisition of an idle line is increased.
