Title: Hydraulic control device
Inventor: NUNOTANI SADAO
IPC: F15B13/042
Filed: 1984-03-16
Abstract: PURPOSE:To prevent the occurrence of hunting as well as to make micromotion control attainable, by constituting each of flow control valves with a poppet valve wholly, while changing discharge control for a variable stroke pump over to open-loop control by means of a control signal being outputted from a control lever. CONSTITUTION:Each of flow control valves is constituted with a poppet valve 31 wholly. And, these poppet valves 31 are made free of opening or closing at will via a pilot valve 34 to be operated by a control signal out of a controller 8 which outputs the control signal according to the operated variable of a control lever group 1. Then, pressure of the higher pressure side between a meter-in poppet and a load check valve 34 is taken out by a shuttle valve 47 and led into a variable relief poppet valve 46. With this constitution, relief pressure of the variable relief poppet valve 46 can be set with the maximum pressure of each actuator load pressure and, what is more, micromotion control is easily performable.

Title: Fixing device
Inventor: MIYAJI NOBORU
IPC: G03G15/20
Filed: 1991-03-14
Abstract: PURPOSE:To allow an operator fo freely select whether a gloss is given or not according to a character image and a color image by variably providing a fixing distance where fixing is carried out with a fixing belt. CONSTITUTION:A movable base 7 is moved by the operation of an adjusting screw 8, and when adjusting rollers 6a and 6b are at positions shown by a full line, the fixing distance (b) from a heating roller 2 is increased. When the adjusting screw 8 is operated and the adjusting roller 6 is moved to the position of an alternate long and short dash line, the fixing distance (b) from a pressure roller 5 is reduced. Thererfore, since the fixing temp, of the fixing belt 4 at the position of the adjusting roller 6 is high without reducing the fixing temp. so much, releasability is low. Consequently, an image is mat. In other words, a glossy or mat image is formed by a temp. change at the time of the fixing.

Title: Facial instrument
Inventor: NAKAYAMA TAKEHISA
IPC: A45D44/22
Filed: 1988-03-04
Abstract: PURPOSE:To make it possible to operate continuous work of suction force and intermittent work of suction force with message effect without changing an attachment, by a method wherein a reed valve is provided for checking an air flow from the main body of a facial instrument to its attachment, and air are provided between a valve room and a suction room of the attachment. CONSTITUTION:When an attachment (20) is turned in one direction to the position where its projections (23) make contact at the end of circular arc-shaped grooves (17), air passages (12) of the main body (1) of a facial instrument are situated at the under surface of a reed valve (14) which is located in the lower room (11) of a double hollow section (21). When a piston (2) is lifted, in such a condition, air passages (32) are closed by the read valve (14) and and the air through the air passages (12) are exhausted from a discharge port (15). Suction force is thus produced continuously in a suction room (25). On the other hand, when the attachment (20) is turned in the opposite direction, the air passages (32) through the main body (21) of the attachment are out of place to the reed valve (14). When the piston (2) is lowered, in such a condition, suction force is produced in the suction room (25), and when the piston (2) is lifted, the air in a pump room (8) is returned into the suction room (25). The suction room (25), thus, is intermittently in suction condition.

Title: Gas injection head
Inventor: HORIE KUNIAKI
IPC: F15D1/08
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To carry out uniform distribution and mixing of gas by means of a simplified structure by use of a choking phenomenon by setting the minimum cross-sectional area of undermentioned minute pores of a gas injection head, used for a thin film vapor growth apparatus where gas is uniformly distributed through many minute pores, to a specific value. SOLUTION: In this gas injection head, uniform distribution of gas is performed not only by providing a resistor to a passage, but also by reducing the diameters of the minute pores until the flow velocities of gas at respective minute pores reach a value satisfying M(Mach)>=1, respectively. The mass flow rate mc (kg/s) at which gas is passed through the minute pore at this time is determined by an inequality. Accordingly, setting only of the minimum cross-sectional area Fc (m2) of the minute pores suffices. In the inequality, (k) is a ratio of specific heats (constant by gas), p1 is the gas pressure (Pa) on the gas-inlet side of the minute pore, and v1 is the gas specific volume (m<3> /kg) on the gas-inlet side of the minute pore.

A recording head 18 is driven at the point of time when the scanning distance of the main body A becomes L or more to perform transfer recording P. When the switch 21 is turned OFF, a buzzer 35 is intermittently driven to inform that scanning is further necessary. When the recording of all of data is finished, the driving of the head 18 is stopped to continuously drive the buzzer 35.
