IPC: F02B3/06
Filed: 1982-12-03
Abstract: PURPOSE:To perform temperature control accurately by inserting a resistor between a glow plug and a regulator then calculating the glow plug temperature from produced voltage and glow plug voltage to control the regulator on the basis of said glow plug temperature. CONSTITUTION:The temperature of glow plug 10 is obtained from resistance of glow plug 10. For that purpose, differential voltage VAB across a detection resistor 13 and voltage VB at the joint with glow plug 10 are used to provide signal from a differential amplifier 17 through input buffer 18 and A/D converter to CPU. CPU is provided signals from engine cooling water temperature sensor 19, starting switch 20, etc. to calculate the glow plug temperature through control program thus to provide control signal such as main relay control signal 21A, sub-relay control signal 21B, etc. through an output buffer. Consequently temperature control of glow plug can be performed accurately.

Title: Automatic focusing and adjusting device of collimating lens system
Inventor: AKANABE YUUICHI
IPC: G03B13/36
Filed: 1981-12-31
Abstract: PURPOSE:To obtain an automatic focusing and adjusting device by the use of inexpensive gate circuits by displacing the position of a light source in such a way that the laser light past a collimating lens is paralleled. CONSTITUTION:When the min. spot of a collimating lens system deviates on an optical axis, gate circuits G1, G2 output the signals of respectively prescribed waveforms with respect to the output of a photodetector PD. The waveform signals are converted to DC with an averaging circuit AVE, and the DC voltage thereof is amplified properly with an amplifier AMP, and is applied to a transducer TR2. The transducer TR2 displaces according to the polarities of the driving voltage and the absolute value thereof, thereby displacing a light source S on the optical axis. For example, when positive voltage is applied, the light source S is moved in a negative direction so as to eliminate the min. spot deviation. The position of the light source S is regulated automatically by the feedback control in the above-mentioned way. Thus, the automatic focusing and adjusting device is realized by using the inexpensive gate circuits with the simple constitution.

Title: Color ink ribbon
Inventor: NIREKI TAKAO
IPC: B41J31/10
Filed: 1986-09-12
Abstract: PURPOSE:To prevent the loss of a processing speed, by dividing a long ribbon into three or more regions at an almost equal interval in the lateral direction thereof and impregnating the region on the central side of the ribbon with ink high in use frequency while impregnating the regions toward both end sides thereof with inks successively becoming lower in use frequency. CONSTITUTION:An ink ribbon 4 is divided into four regions at an almost equal interval in the lateral direction thereof and four regions are impregnated with different inks so that the central regions are impregnated with inks high in use frequency to form a light blue region 4a, a black region 4b, a reddish purple region 4c and a yellow region 4d.

The reddish purple and yellow regions 4c, 4d are used by further moving the lower end side of the swing arm 3 in the spaced-apart direction with respect to the cartridge main body 2. Since the ink part high in use frequency is arranged on the central side, the operation distance at the time of the change-over to the other colors becomes short and the loss of a processing speed is reduced.

Abstract: PURPOSE:To omit a large number of manual works in an input mode of a diagram of facilities and at the same time to prevent an input mistake, by recognizing interactively the input of the data on the diagram of facilities from the image information and supplying automatically the recognized input to a data base. CONSTITUTION:A diagram 20 of facilities is put into an image reader and stored in the form of a data file 8a after undergoing the elimination of filtering noises through an input step 13. While the latest data on a topographical map 21 is previously stored in a data base 8b for topographical map. Both the diagram 20 and the map 21 are put on each other in a step 14 and displayed in different colors on a graphic display 4. In such a case, the positions of the diagram 20 and the map 21 are matched with each other in the step 14. Then a mouse 12 picks the area near a symbol of facilities in a step 16 and therefore the image data on a set area is processed by the software on the basis of said picked point. Thus the form of the symbol is recognized together with the type of the symbol decided. Then the coordinate data is detected and stored in a data base 8c for facilities. The same procedure is applied also to the adjacent symbols. Thus the vector data is obtained. This action is repeated for storage of the desired data into the base 8c.

Electrons are injected to the layers 6 from the discontinuous sections (the ends of each period) of conduction bands, and accelerated at DELTAEcproportional (x2-x1). Accordingly, when such period structure is formed, hot electrons are injected repeatedly even on a thick active layer (between the emitter and a base) completely burying a cavity on a Schottky electrode, thus resulting in the expectation of response at high speed.
