Title: Optical switch array type printer
Inventor: TATENO KIMIO
IPC: B41J2/44
Filed: 1985-12-18
Abstract: PURPOSE:To realize small size, low noise, and high speed of the titled printer, and to improve the printing quality by utilizing a switching effect of total reflection and transmission generated by a variation of a refractive index by injecting a carrier, as a switch array. CONSTITUTION:Beams from plural pieces of semiconductor lasers 1 are condensed by a lens optical system 2 containing a cylinder lens, and each point of an optical switch 3 is irradiated. The beam which has been brought to a waveguide in the optical switch is brought to an image formation on a photosensitive drum 5 by a SELFOC array lens 4. The optical switch array 3 is brought to a dot formation in parallel to every one line of printing. The optical switch array 3 is driven by a parallel driving circuit 6. The printing density is determined by the number of elements of an optical switch array. With regard to one element of the optical switch array, the light beam is made incident on a waveguide 11, and made to reach a carrier injection area 12. In case no current is injected to this area 12, the light is brought to a total reflection, and when it has been injected, a refractive index decreases and the light beam transmits. According to this system, a small size, low noise, and high speed of a printer are realized, and the printing quality is improved.

Title: Oil tester
Inventor: YAMADA TOYOO
IPC: G01H11/08
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To obtain an oil tester by which the degradation degree of an oil can be discriminated properly by transducing an electric signal into a sound- wave signal with a sound-wave transmitting element, transmitting the signal into the oil, receiving it with another sound-wave transmitting element and transducing it into an electric signal and judging the degradation degree of the oil from an output. SOLUTION: An electric signal, at about 20kHz or higher, which is transmitted from a transmitter 2 is amplified by an amplifier 3, an electrostrictive element 4 for transmitting is excited, and ultrasonic waves are generated. The ultrasonic waves are propagated inside an oil which is put into an oil tank 5 for measurement, they are received by an electrostrictive element 6 for reception, their electric signal is detected by a detector 7 so as to be amplified by an amplifier 8, and its voltage level is displayed by an indicator 9. The level is compared with a level in the case of a new oil, and the oil is judged to be degraded when the voltage level is low.  In this manner, the degradation of the oil can be judged on the basis of change in the propagation factor of the ultrasonic waves without being affected by a coloring component or the like, and the existence of the degradation can be judged properly and simply.

Title: Method for displaying information with the small number of digits
Inventor: MOGI EMI
IPC: G06F3/048
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To eliminate the limit of the quantity and the size of information to be displayed by displaying only digits under the prescribed number of digits of information in a second display form when information to be displayed consists of digits more than the prescribed number of digits. SOLUTION: When a processor 32 instructs a picture generation part 33 to generate an input picture, the picture generation part 33 reads out necessary data from a memory 34 and constitutes display data such as a calendar part on a picture memory 36. When a key inputted from a keyboard 31 is a numerical key, the processor 32 instructs an input frame generation part 35 to display the numeral in the frame. When an 'input key' is depressed, the processor 32 stores a numerical value in the input frame in a memory 34. After then the processor 32 investigates the numerical value stored in the memory 34 and when it consists of one digit, the processor 32 instructs the picture generation part 33 to display the numerial value in black.  When the numerical value consists of two digits, the processor 32 instructs the picture generation part 33 to display the numeral of the lowest digit in blue when the numerical value is smaller than twenty and to display the numeral of the lowest digit in red when the numerical value is more than twenty.

Abstract: PURPOSE:To detect the malfunction of a LD by maintaining the temperature of the LD constant, monitoring the emitting power of the LD, and feeding it back. CONSTITUTION:The efficiency eta of a LD and the value of a light emitting threshold current value Ith are varied according to the environmental temperature, ageing change, etc. The temperature of the LD 14 is kept constant, the emitting power of the LD 14 is monitored by utilizing it, and fed back thereby to provide a so-called APC(automatic power control) function.

In case of an optical magnetic memory, the operating states of a LD driving circuit has three modes of recording 12, reproducing 3, and erasure 5. If LD light emitting tests of reproducing and erasing modes are executed in a state that a disk is not always inserted into a driving state at the time of start of optical magnetic memory drive, the etaand the Ith can be known to detect the malfunction of the LD 14.
