Title: Ink jet recorder and recording head mounted in the same recorder
Inventor: KOIZUMI RYOICHI
IPC: B41J25/34
Filed: 1988-12-20
Abstract: PURPOSE:To discriminate the propriety of a recording head to be mounted on a recorder body by previously inspecting the operating characteristics of a discharge heater and a temperature sensor. CONSTITUTION:A head cartridge 14 has a recording head including an ink discharge port 26 and composed by adhering a heater board 27 and a ceiling plate 30. A discharge heater 3 made of an electrothermal transducer, and a temperature sensor 2 for detecting the temperature of a recording head to suitably control a head temperature are provided on the heater board 27. A CPU 11 executes a process for inspecting the operating characteristics of the discharge heater and the temperature sensor to inspect whether the discharge heater 5 and the temperature sensor 2 are suitable or not. When it detects the ON of the power source of a recorder, it drives a head driver 5A for preliminarily discharge to electrify the discharge heater 5. Then, it reads the detected value of the temperature sensor 2, compares it with a predetermined temperature range stored in a RAM, and judges whether it falls within the range or not. The propriety of the discharge heater and the temperature sensor to the recorder body is judged by this process.

Abstract: PURPOSE:To realize the speedy operation of a fork for a light load by installing a detecting means for detecting the output value of a hydraulic pump and a judging means for the comparison-judgement with a set value and suspending the revolution of an electric motor or carrying out the power running of the electric motor when the fork is lowered by a light load and the electric motor is in the regenerative operation disabled state. CONSTITUTION:If a lift lever 5 is operated downward to lower a fork in the nonloaded state or light-loaded state, when a tilt lever 10 is in nonoperation, the flow rate of the oil returned into a pump 1 from a lift cylinder 7 reduced, and an L-signal is outputted from a lift side pressure switch 8a. Since the tilt lever 10 is in nonoperated state, the L-signal is outputted also from a tilt side pressure switch 11a, and the L-signal is outputted from the first OR circuit 22a of a discriminator 22. If a speed adjusting switch 25 is held in the nonoperated state, the L-signal is outputted, and when said switch 25 is operated, the second OR circuit 22b outputs the L-signal into a controller 20. Therefore, the controller 20 cuts off the supply of electricity into an electric motor 21 from a battery 24.

Title: Apparatus for ultrasonic treatment of very dilute alcohol
Inventor: HIROSE MASANAO
IPC: C07C47/02
Filed: 1990-11-28
Abstract: PURPOSE:To obtain an alcohol or an aldehyde from a very dilute alcohol solution using a low energy by arranging a vibration member in the inside and equipping an ultrasonic machine unit accommodating the very dilute alcohol solution and tightly sealed. CONSTITUTION:Cavitation is produced by making a vibration member 20 ultrasonically vibrate in an ultrasonic machine unit 16 while supplying oxygen suitably adjusted, e.g. to some degree dilute oxygen concentration, e.g. by adding carbon dioxide gas to compressed air through a connecting opening 25 and a vaporized alcohol is oxidized thereby. The above-mentioned oxidation is remarkably promoted by cavitation to be immediately converted to an aldehyde and the generated aldehyde is accommodated in a liquid storage tank 33. In this case, a solid type catalyst may be placed in the neighborhood of a bumping- proof board 28 in the ultrasonic machine unit 16 for more complete conversion to the aldehyde. When methyl alcohol or ethyl alcohol is used as the very dilute alcohol solution 91, formaldehyde or acetaldehyde is obtained.

Title: Driving method for led
Inventor: HARAJIRI MASAO
IPC: H04B10/50
Filed: 1987-12-19
Abstract: PURPOSE:To obtain light emission intensity similar to the time of low speed even when an LED is driven at high speed, and to realize long distance reach by lowering the duty ratio of a carrier signal by making the duty ratio of a subcarrier signal be 50% at least. CONSTITUTION:A driving pulse to be impressed upon an input terminal 1 is inversion-amplified by a buffer amplifier consisting of a transistor(TR) Q1, resistors R1, R2 and a gate diode D1, and the TR Q2 turns on/off as receiving the output of the TR Q1, and drives the LED 2. A signal to be impressed upon the input terminal 1 is the signal (c) that the RZ signal (a) of pulse width PW is pulse-amplitude-modulated PAM) by a subcarrier (b) whose duty ratio is 50%. Thus, because the pulse forward current of the LED of a light transmitter, etc., is increased by a PAM wave using the subcarrier whose duty ratio is 50% at least, the luminance of a light intensity modulated wave can be increased, and the light output of it can be increased.

Title: Focusing error detector
Inventor: KIMURA YASUO
IPC: G11B7/135
Filed: 1988-12-20
Abstract: PURPOSE:To obtain a focusing error detector with superior stability for temperature by setting the travel of a light spot on an optical detector according to the fluctuation of oscillation wavelength in a light source in the same direction as that of two light spots and suppressing the amount of travel of the light spot within prescribed times the parting line width of the optical detector. CONSTITUTION:A focusing error signal Sfe is given as equation I assuming the output of segments 31-34 of the optical detector 22 as V1-V4. Therefore, the focusing error signal is offset and goes to zero even when the positions of the light spots 25 and 26 are deviated upward or downward from a first parting line 23 in parallel optically with the knife edge of the optical detector, and no focusing error signal offset occurs. Thereby, the parting line of the optical detector 22 and the position of a convergent point on the parting line are decided so that the travel of the light spots 25 and 26 on the optical detector according to the fluctuation of the oscillation wavelength of the light source can be set in the same direction as that of the two light spots and also, the amount of travel of the light spots can be suppressed within 2.8 times the parting line width of the optical detector. In such a way, it is possible to obtain the focusing error detector having remarkably stable error detecting characteristic against the fluctuation of the wavelength of the light source.
