Title: Blood dialyzer
Inventor: HARADA YOSHIMITSU
IPC: A61M1/14
Filed: 1987-11-17
Abstract: PURPOSE:To accurately, automatically measure and control an amount of removed water so as to safely dialyze blood, by converting a momentary amount of removed water periodically measured into an amount of water to be removed for a certain time period (time period for completing dialysis) and calculating the difference between the converted value and an amount of water-removal previously set. CONSTITUTION:Pulse counts indicating an inflow amount and an outflow amount of a solution to be dialyzed are periodically detected with oval meters 3 and 6, and are sent as pulse signals to a means 11 for calculating momentary amount of removed water. A converting means 31 for amount of water-removal calculates a speed ot a momentary water-removal from an increment of pulse counts, which indicate momentary amounts of removed water and which are periodically calcuated by the means 11, and then, using the speed calculated, converts the momentary amounts of removed water into an amount of water to be removed for a time period for completing dialysis. A signal from the means 31 is sent to a means 32 for calculating difference between converted value and set value, where the signal is compared with an amount of water-removal previously set by a means 10 for setting amount of water-removal and thereby the difference between both the values is calculated. The difference is converted into a membrane pressure difference to be accorded with a value set by a means 13 for setting constant membrane pressure difference. The amount of water-removal is accurately controlled in the above manner.

Title: Intake/exhaust valve device for internal combustion engine
Inventor: YAMADA SHIGEKI
IPC: F01L3/00
Filed: 1989-11-09
Abstract: PURPOSE:To prevent the adhesion and accumulation of foreign material to an engine valve by detecting the position of a cam so as to drive a high frequency vibrator during the open time of the engine valve driven by the cam and thereby vibrate the engine valve. CONSTITUTION:At the engine operating time, an engine valve 1 is switched being elevated by a cam 12. While a valve opening detecting sensor 28 and a valve closure detecting sensor 29 output detection signals respectively in association with the change-over of the engine valve 1, an electrostrictive vibrator 20 is vibrated. As the upper end face of the electrostrictive vibrator 20 is constrained to the cam 12 through a shim 21, the engine valve 1 is excited axially with high frequency by the vibration of the electrostrictive vibrator 20. As a result, foreign material on the verge of being adhered to the engine valve 1 is shaken off. Moreover, as the excitation of the engine valve 1 is performed during the valve open time, damage caused by the vibration of a contact part between a seat 7 and a valve head part 2 can be avoided.

Title: Crane and attachment for increasing hoisting capacity thereof
Inventor: BECKER THOMAS K
IPC: B66C23/36
Filed: 1989-11-09
Abstract: PURPOSE: To adjust increase of lifting capabilities of a crane by providing a counterweight carrier for holding a counterweight so that it may be moved between one or more connecting parts between segments and along the length of a support beam. CONSTITUTION: In lifting a load, a counterweight 62 arranged on a beam rear end 112 generates a moment larger than a moment generated by the load. When a carrier 92 of the counterweight 62 is moved forward along a support beam 84, a moment to be generated on the counterweight 62 is equalized to a moment to be generated by the load and then decreased lower than it. In this case, energization of a cylinder acts on an outer member to prevent the movement of a groove of the outer member in relation to the pin until the counterweight 62 is moved by passing the position in which a moment by the counterweight 62 is equal to a moment by the load. Next, when the counterweight passes the balance point, a mast is turned upward, and the beam rear end 112 is lowered.

Filed: 1990-10-31
Abstract: PURPOSE: To cancel crosstalk by a method, wherein wire segments are connected in series to each other by a strip conductor, which gives a magnetic interconnecting in a direction opposite to the interconnection between the wire segments. CONSTITUTION: A current is made to flow along the side on one side of the sides of a peripheral part 46 toward a laser 22 and is returned along the other side of the part 46 within each partial loop 58 in the surface of a covering 20. In each of signal channels, the current in made to flow clockwise in each loop 58, and a magnetic flux is generated. This magnetic flux passes through the loop in the direction vertical to the surface of the covering 20, is circulated on the vertical surface of the magnetic flux to exchange the negative interconnection coefficient of the loop 58 for the positive interconnection coefficient of a loop 58 adjacent to the loop 58, and the negative interconnection coefficient is given to the loop 58 adjacent to the loop 58.  Accordingly, the adjacent signal channels are magnetically linked to each other by the positive and negative components of the mutual inductances. The lengths and width of a parts 46 in the loops 58 are adjusted and can be made equal with each other, so as to offset the negative and positive components of the mutual inductances. By constituting the interconnection system of an electric circuit in this way, crosstalk can be reduced.

Title: Laser beam printer
Inventor: UCHIYAMA MASAJI
IPC: G03G15/04
Filed: 1990-10-29
Abstract: PURPOSE:To reduce the area of a light receiving part in keeping an allowable value of slippage from the optical center ensured intact as well as to make a reduction in the jitters realizable by forming the light receiving part of a beam detecting means for detecting a horizontal synchronous signal into a polygonal form of a circle or more than a pentagon. CONSTITUTION:A beam detecting means is used for a horizontal synchronous signal BD signal detecting part 115 in a laser beam printer, and it has a light receiving surface 2 for each photoelectric transfer of a package 1 and the beam detecting means. This light receiving surface L2 is formed into a round shape which will get the light receiving surface of about 78% comparing with a square case with a diameter of the circular light receiving surface. Therefore junction capacitance between PN junctions is reducible, and the buildup of an output waveform can be yet earlier. Thus, even if a light receiving area is reduced, an allowable value from the optical center of a laser beam can be ensured on the circular light receiving surface. With this constitution, the junction capacitance between the PN junctions is increased and thereby a speed of response becomes quickened, thus a reduction in the jitters is well promoted.

Title: Linear type optical encoder
Inventor: ONO YUTAKA
IPC: G01D5/36
Filed: 1990-10-30
Abstract: PURPOSE:To obtain the detected commutation-angle signal directly from the detected signal of an encoder and to perform the commutation control of a motor by making the pitch of the slits of the encoder equal to the pitch of the gear teeth of the stator of the motor. CONSTITUTION:The pitch of the slits of an encoder 2 is made equal to the pitch of the gear teeth of a stator 11 of a motor 1. Therefore, the phase shift of the slits detected with the encoder 2 becomes the phase shift itself between the gear teeth of the stator of the motor and the gear teeth of a mover 12. Thus, the detected commutation-angle signal can be directly obtained from the detected signal of the encoder 2. The encoder 2 can be used for controlling the commutation of the motor 1. When the change of the phase shift is computed, the position of the mover of the motor 1 is detected. The speed of the mover of the motor 1 can be detected on the basis of the fluctuating period of the value of the phase shift. Thus, the controls for the commutation, position and speed of the motor 1 can be performed at the same time.
