IPC: F02D41/06
Filed: 1992-04-07
Abstract: PURPOSE:To provide a fuel control device for an internal combustion engine which prevents the internal combustion from stopping after start-up by determining adequate injection quantity at the time of start-up corresponding to a ratio of alcohol content in mixed fuel, and gradually decreasing injection quantity. CONSTITUTION:A fuel control device for an internal combustion engine 22 having a main injector arranged in each cylinder and a cold injector arranged in an intake manihold while using alcohol mixed fuel as fuel, is provided with a means 208 which detects a ratio of alcohol content in the alcohol mixed fuel and means 209-211 which detect quantity of state representing driving condition in the internal combustion engine. The fuel control device for internal combustion engine 22 is also provided with a means which distinguishes whether the internal combustion engine is in a starting condition or not from the driving condition quantity and a means which determines an initial value of fuel quantity at the time of start-up injected from the main injector 2041-2044 and the cold injector 205 and by which the higher the ratio of alcohol content, the faster the starting time for decreasing fuel quantity at the time of start-up.

Title: Character dot pattern signal generator
Inventor: KAJIMOTO KAZUHIRO
IPC: G09G5/24
Filed: 1989-04-03
Abstract: PURPOSE:To output the dot pattern having high printing quality by deciding an interval in the vicinity where two line segments generated when a reduction out line is generated are crossed and limiting the generation of a dot concerning a part where the interval is relatively decreased in comparison with a dot size. CONSTITUTION:An outline arithmetic circuit 3 transforms the coordinates of a starting point, ending point, control point or auxiliary point, which is read from a storage circuit 1 by a read circuit 2, so as to be coincident with a character size and the data concerning reduced characters are outputted to a correction arithmetic circuit 4. According to the contour information from the outline arithmetic circuit 3, the correction arithmetic circuit 4 determines the thinning- out number of the dot in correspondence to the interval between the line segments in the vicinity of the crossing point. A dot pattern generation circuit 6 outputs the dot pattern based on the outline data from the outline arithmetic circuit 3 or correction arithmetic circuit 4.

Title: Low-voltage operational amplifier and its method
Inventor: DOTSON ROBERT N
IPC: H03F3/30
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a conventional operational amplifier receiving its power from a battery. SOLUTION: The low-voltage operational amplifier 10 is operated at a voltage range of 1-8V over a temperature range of 0 to 70 deg.C. An input stage 12 employs an N-channel depletion mode MOSFET, to amplify differential inputs and for maintaining a prescribed mutual conductance. A source follower MOSFET 13 provides a single gain to a base of a current sink transistor(TR) 18 in the transfer of an AC signal 'stage 1 output'. A sink control circuit 14 and a source-control circuit 22 generate a base drive current in TRs 18, 24. The input signal controls the sink TR through an AC signal path for a 'sink path' signal or a 'source path' signal is generated through a trans-linear loop 16. An output stage provides a sink and source current of about 50mA.

Title: Safety device
Inventor: KAWAMURA TAKESHI
IPC: B66C23/88
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To easily make ineffective a second boom overlifting device during operating a tower crane. SOLUTION: During operating a tower crane, a harness 42 for a tower is connected to a body relay box 40 provided on a revolving structure 3. Since the standing up of the tower is performed in state where the relative angle of a jib is fixed to a specified angle (110 degrees or 162 degrees), a jib releasing switch is turned on. Thus, a circuit with which a second boom overlifting relay 26 and a second boom overlifting switch 32 are short-circuited, is cut off, and a second boom overlifting relay 25 is not energized even when the second overlifting switch 32 is turned on. As a result, solenoids 61a, 62a of a solenoid selector valve for stopping the driving of a derricking winch, are not excited, and the second boom overlifting device is made ineffeictive.

IPC: F25B43/04
Filed: 1989-04-06
Abstract: PURPOSE:To prevent leakage of surrounding air into working refrigerant and improve economical reliability by a method wherein cooling of an electric motor is carried out through specified working medium liquid purified not to contain air and a gas extracting device is automatically operated before starting operation of a heat pump compressor. CONSTITUTION:As a working refrigerant, refrigerant having compound with a molecular formula of CkHLClmFn (where, k is an integer more than 2, l is an integer more than 1, m+n is an integer more than 1) and further having an inner pressure of an evaporator less than an atmospheric pressure is applied. An electric motor 24 for use in driving a compressor 1 is cooled by working refrigerant liquid fed through a refrigerant passage 14 from a condensor 2 and sent by a pressurizing device 15. In order to prevent dissolution of the working refrigerant at the electric motor or an outlet port of the compressor, a gas extracting device 30 for use in extracting air leaked into the refrigerant passage is provided, a pressurizing device 18 is arranged within a pipe 17, resulting in that the gas extracting device 30 can be operated before starting the heat pump operation. With such an arrangement as above, there is no fear of dissolution of refrigerant even if the working refrigerant acting as one for cooling the electric motor is sent from any place due to the fact that a concentration of air within the heat pump system is low.

IPC: H04N1/113
Filed: 1991-03-27
Abstract: PURPOSE:To prevent the deviation of a printing start position or the change of the dot diameter in a page by inhibiting the difference of laser power in the page. CONSTITUTION:A laser ON/OFF control part 62 controls lighting and extinction of a laser diode in accordance with printing data in the case of the inside of a printing area. In the case of the outside of the printing area, the laser diode is turned on for the purpose of detecting a laser beam by a start sensor. The feedback enable output is not outputted to a laser power control part 63 till the end of printing of one page. Then, a latch circuit 30 latches a digital value till the end of printing of one page. Consequently, an analog output A from a D/A converter 31 is not changed during printing of one page. The digital value latched in the latch circuit 30 can be varied between the page and the next page.

Title: Device for feeding film at slow speed for projector
Inventor: HANAOKA SHIYOUJI
IPC: G03B31/00
Filed: 1978-07-14
Abstract: PURPOSE: To readily execute the heading of a film at recording time in a sound projector by starting a device for feeding a film at slow speed via a slow speed feeding switch only when a projection lamp is set at off position to become preheating state.  
     CONSTITUTION: When a main switch knob 30 is set at off position 33, a motor 71 is not driven, and a lamp 15 becomes in preheating state under the control of a cam 74 to allow a microswitch 76 to be connected to a low voltage side. When a normal rotation slow speed feeding switch 37 is depressed in this state, a microswitch 60' is closed to thereby allow the motor 71 to be normally driven at slow speed to thus project a movie film image on a projection glass on a viewer. When a reverse slow speed feeding switch 38 is depressed, the motor 71 is driven in reverse direction at slow speed. Thus, even if the film is accumulated on an optical path for long time in this slow speed drive state, it may not be burnt due to the radiation heat of the lamp.
