Title: Spray device for manipulator
Inventor: WAKI AKINORI
IPC: B25J9/00
Filed: 1983-03-30
Abstract: PURPOSE:To simplify the spraying operation by a manipulator by providing a case holder for holding a spray case, and permitting the push of the operating part of the spray case when the holder is coupled to the manipulator. CONSTITUTION:A spray case 10 contg. a desired fluid to be sprayed is fixed and held to a case holder 20 and is supported on a stand. A compression spring 32 is compressed in this state and the tip of a connecting pin 30 is retreated to the outside of a finger rest 27 and therefore the spray device is removed from the stand by inserting the fingers 25, 26 of a manipulator 24 into the finger rests 27, 28. Then the pin 30 is inserted by a compression spring 32 into the hole 25A of the finger 25 and both are kept coupled and held. The manipulator 24 is thereupon moved to direct a spray nozzle 13 toward an object. When the space between the fingers 25, 26 is closed, the top end 36A of a pushing lever 36 pushes the operating part 12 of the case 10.

Title: Steering stabilizer for car
Inventor: KOUSAKA MASAO
IPC: B62K5/00
Filed: 1982-03-31
Abstract: PURPOSE:To improve the steering performance by making the center of gravity of chassis movable back and forth thereby preventing from shifting to the front side at the cornering. CONSTITUTION:When turning a steering wheel to the left or right by theta from the straight-advacing state, the wheel post 11 and the engaging member 32 will rotate in same direction with the wheel 12, and the bent section 32a or 32b of said member 32 will displace the piston rod 30a or 31a into the cylinder body 30c or 31c. Consequently the operating oil in the chamber D or F in the hydraulic cylinders 30, 31 is fed forcibly through a hydraulic hose 36 into the chamber B of the hydraulic cylinder 25 to shrink the hydraulic cylinder 25 thus to displace the rear wheel 17 forwards. Consequently the center of gravity G1 when advancing straight will displace forwards to the position G2 enabling smooth cornering.

IPC: B41J2/44
Filed: 1989-03-07
Abstract: PURPOSE:To eliminate development of a cache memory even if a paper jam etc., occurs by writing or clearing the memory in synchronization with a printing operation. CONSTITUTION:When print data, etc., are input from a host computer 1, the data are stored in an input buffer 2, vector coordinates, a character pitch, an attribute, etc., are output from a character information memory 3 based on the stored data, and a bit map is developed. Then, a cache memory converter 5 inhibits to write in a cache memory 4 until a signal of informing the end of print of previous page by a print controller 8 is detected by a print end detector 10 to prevent bit map data from damaging. Thereafter, when the detector 10 detects the end of page printing, it judges the state of the memory 4 to execute writing. Thus, a labor of redeveloping of the bit map in the memory when a trouble of the controller 8 occurs can be omitted.

IPC: C07C323/22
Filed: 1987-03-10
Abstract: PURPOSE:To obtain the titled compound useful as a crosslinking agent, in high yield and purity, by adding an aldehyde containing active hydrogen to a mixture of an inert solvent and sulfur monoxide and reacting the components with each other. CONSTITUTION:The objective dithiodialdehyde of formula II can be produced by condensing an aldehyde of formula I (R1 and R2 are 1-8C alkyl) containing active hydrogen with sulfur monoxide. The reaction is carried out by adding the compound of formula I to a mixture of an inert solvent (e.g. benzene, toluene and methylene chloride) and sulfur monoxide. The sulfur monoxide is constantly maintained in more than equimolar amount based on the compound of formula I during the reaction. The residue of the compound of formula I can be essentially eliminated by this process and the contact with by-produced hydrochloric acid gas can be avoided. The objective compound can be produced by this process irrespective of the necessary time for the addition of the raw material.

Title: Semiconductor device
Inventor: KUMAGAI NAOKI
IPC: H01L27/088
Filed: 1990-03-05
Abstract: PURPOSE:To restrain a current flowing through an element and to carry out load shortcircuit protection by making substrate electric potential of a current detecting MOSFET common to one main electrode of an output element and by detecting load shortcircuit by a voltage which is applied to an element using change of its gate threshold value. CONSTITUTION:When load shortcircuit develops and a voltage applied to an output element 1 rises, a substrate electric potential of a MOSFET 5 rises; therefore, its gate threshold voltage rises, the MOSFET 5 turns OFF and a MOSFET 4 turns ON. Thereby, gate electric potential of a MOSFET 1 lowers to a divided value by an ON-resistance of a gate resistance 2 and an MOSFET 4; or when designed to operate a MOSFET 4 in an active region, it lowers by a voltage drop due to the gate resistance 2 caused by a saturation current of the MOSFET 4, thereby reducing a shortcircuit current during shortcircuit. Thereby, it is possible to reduce loss generated at an output element during load shortcircuit, to prolong a period until element breakdown, and to protect an element from load shortcircuit even in a slow protective circuit which is usually used.
