Title: Recording head
Inventor: OKI YASUSHI
IPC: B41J2/055
Filed: 1998-02-23
Abstract: PROBLEM TO BE SOLVED: To provide a recording head capable of recording a high resolution image by ejecting small ink drops. SOLUTION: This recording head 10 has a cantilever structure wherein an elastic member 12 is supported by a vibration generating means 16 at a base end section 14. As a result of the structure, the vibration generating means 16 is vibrated by a predetermined frequency, the elastic member 12 is resonated and an ink drop 48 is ejected from a vibration face 45 in the vicinity of a tip section 18 so that a dot is recorded on a recording paper. Thus, a high resolution image is recorded by the small ink drops 48. At that time, as the elastic member 12 is skirt-shaped at the base end section 14, it is possible to prevent stress concentration to the base end section 14 during the bending vibration, thereby stabilizing the bending vibration. As a result, flight condition of the ink drop 48 is stabilized, thereby achieving high resolution of image recording.

Inventor: MASAGO YUKIO
IPC: H02H3/16
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To surely protect a relay from grounding even if banks are operated separately or parallelly. SOLUTION: This device is constituted of automatic-reset relays 1, 2 which are operated by the currents of CT1, CT2, an automatic-protection relay 0 which is operated by the current of CT0, a circuit of an AND10 and a timer T1 which trips a breaker CBI when the relay 1 operates under the condition that the relay 0 operates, a circuit of an AND20 and a timer T2 which trips a breaker CB2 when the relay 2 operates under the condition that the relay 0 operates, and a circuit of ANDs 10, 20, 120 which trips a bus-linked breaker CB 12 when the relays 1, 2, 0 operate. When an earth F occurs at the parallel operation of banks and then currents Io1 , Io2 flow, the CB12 is tripped by the output of the AND120 before the T1, T2 deliver outputs and thereby the current Io2 becomes zero. After that, the CB1 is tripped by the output of the T1.  When the relays 1, 2 keeps operating, it is determined that the operation of the relays 1, 2 is due to circulating current and then an alarm signal is output from an AND12 through a timer T3.

IPC: G06F3/00
Filed: 1979-04-05
Abstract: PURPOSE: To reduce a space where set data can be written simply and rapidly, by providing a nonvolatile memory to read out stored peculiar data.  
     CONSTITUTION: Mode switch MCL is set to the test mode, and set data peculiar to a terminal is successively input to register RG1 by numeric keyboard TK. When set of function keyboard FK is depressed at the last of input, data from register RG1 is stored in shop number register RG3 and device number register RG4 through gate group GT2 and is stored in nonvolatile memory MEM together with the output of check data generating register RG2 by the output of input end detection circuit IED. Then, memory control part MMC reads the check bit to perform check. In case of normalcy, switch MCL is switched to operating. In case of error, alarm is issued to give the operator warning so that set data cannot be used. Thus, when transfer of keyboard FK is depressed, set data is read, and set data is transmitted through line control part LCT following normal data. Consequently, the set board can be needless to reduce the space.

Title: Control circuit for starter
Inventor: SUZUKI TOSHIO
IPC: F02N11/08
Filed: 1978-04-10
Abstract: PURPOSE: To automatically de-energize an electromagnetic switch through a simple construction, by connecting one end of an electromagnetic switch coil of a starter to an auxiliary diode terminal of an AC generator so that a prime mover rotates by itself.  
     CONSTITUTION: Wnen a main switch 2 and a key switch 3 are turned on, a charge lamp 13 provided between the key switch 3 and a terminal L and the electromagnetic switch coil 5 of the starter 4 are energized. Because the resistance of the lamp 13 is much higher than that of the coil 5, the voltage of the terminal L is much lower than that of a battery. Thus, a desired current flows through the coil 5 to start the prime mover. When the prime mover rotates by itself, the AC generator 11 produces power. The voltage of the terminal L is equalized to that of the battery by a rectified voltage produced by passing the power through auxiliary diodes 11A. As a result, the coil 5 is automatically de-energized stop the starter 4.
