Title: Magnetic card printer having cleaner
Inventor: ADACHI MASATO
IPC: G11B23/50
Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic card printer which can print cards with high quality by preparing a magnetic head part, a suck/ejection sensor which detects the suck and ejection of magnetic cards, and a cleaner part which cleans the printing side of a magnetic card that has been sucked and printed. SOLUTION: The print contents are written into a magnetic card 12 via a magnetic head part 15, and the card 12 is carried to a suck/ejection port 14. Under such conditions, the cleaner part 1 is kept in its saving state and accordingly the card 12 is not cleaned and ejected. The suck/ejection sensor 13 detects that the card 12 is ejected through the port 14 and then notifies the end of an operation. Then, the sensor 13 detects that a printed card 12 is sucked through the port 14. Thus, a feed roller 2b is revolved in the card sucking direction and at the same time, a drive current flows to the part 1. Then, the part 1 is pressed by the printed card 12 and the printing side of the card 12 is cleaned. In such a constitution, the card 12 can be printed with high quality.

Title: Absorption type freezer
Inventor: YAMAGUCHI AKINORI
IPC: F25B33/00
Filed: 1991-10-02
Abstract: PURPOSE:To enable refrigerant to be automatically refined by a method wherein a specific weight of the refrigerant is detected by a float switch and the refrigerant is automatically transferred to an absorption device by a refrigerant pump when the specific weight of the refrigerant is increased. CONSTITUTION:At an evaporator 1, refrigerant is dispersed by a refrigerant pump 3 to an evaporator tube through a refrigerant spraying pipe 4 and a refrigerant spraying duct 5. A refrigerant tank is provided with a float switch 6. The float switch has a function to float when the specific weight of the refrigerant is or more and in turn to sink when the specific weight is 1.1 or less. It is further provided with a refrigerant pipe 7 and a solenoid valve 8.

Inventor: ASAMI MASAYOSHI
IPC: F16C17/02
Filed: 1999-09-09
Abstract: PROBLEM TO BE SOLVED: To prevent lubricant from flowing out due to the thermal expansion of the air in a bearing. SOLUTION: A bearing clearance 10 has reservoirs 12 and 16 to minimize the dispersion in the quantity of the lubricant contained in radial bearing sections 13 and 15 and a recess 14, etc., and sealing sections 11 and 17 on the aperture sides of the reservoirs 12 and 16.

Title: Emergency shutdown device for liquid storage tank
Inventor: MITSUISHI MASAHIRO
IPC: F16K17/36
Filed: 1995-10-02
Abstract: PROBLEM TO BE SOLVED: To prevent liquid such as drinking water, stored in a liquid storage tank, from flowing out due to an earthquake. SOLUTION: When an earthquake sensor is actuated sensing vibration (earthquake) of set acceleration or more to cut off a current to a solenoid 7, the magnetic force of the solenoid 7 vanishes, and the solenoid 7 moves into an off position. A hook member 82 constituting engaging/disengaging mechanism 8 is thereby actuated to release lock to a rod 51, and a valve element 4 is turned by its own weight into a position of closing a takeoff port 2a of a liquid storage tank 2. When the valve element 4 closes the takeoff port 2a, liquid pressure presses the valve element 4 into its closing position, that is, the outflow of liquid can be cut off at the takeoff port 2a part opened into the liquid storage tank 2.  As a result, even if a feed pipe 3 or the like additionally provided outside of the liquid storage tank is damaged in any position by the earthquake, liquid stored in the liquid storage tank 2 can be positively secured as long as the liquid storage tank 2 is not damaged.

Title: Multifunctional information processor
Inventor: OUCHI TETSUYA
IPC: H04N1/00
Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To make a multifunctional information processor, which performs recording on a form by a recording means while placing a read means in operation, namely, being able to perform what is called the simultaneous copying operation, without not rejecting copy function even while an recording means is in operation. SOLUTION: When a copy key is operated with a document set on an image scanner device, read image information is stored in a buffer memory (S12) by placing the image scanner device in operation even if a laser printer is in recording operation (Y10: Yes), and the image information is read out and recorded (S14) after the recording operation of the laser printer ends (Y13: Yes). Consequently, even while the laser printer is in recording operation, the copy function is not rejected and the image information read by the image scanner device can be stored in the buffer memory in advance, thereby enabling acceleration of copy function.

IPC: G06F13/24
Filed: 1990-09-25
Abstract: PURPOSE:To shorten the processing time of a programmable controller despite the increase of access frequency to an I/O bus by providing an access controller and a wait controller which cancels a wait state after keeping this state until a fixed time required for a CPU to have an access to the I/O bus elapses. CONSTITUTION:A bus controller is provided with a pair of tristate buffers 11a and 11b which are set between the bus terminals of the CPU 1a and 1b and an I/O bus 2 respectively. Both buffers 11a and 11b are controlled by an access controller 12 and a wait controller 13. Then the connection secured between the CPU 1a and 1b and the bus 2 is controlled. When the access of the CPU 1a is through to the bus 2, the CPU 1b is kept in a wait state by an exclusive wait signal and this wait state is canceled after a fixed time. Thus the hardware is available and therefore the processing time of a programmable controller is shortened despite the conflict of access requests.
