Title: Distributor for internal combustion engine
Inventor: FUJIWARA HIROSHI
IPC: F02P7/02
Filed: 1986-12-26
Abstract: PURPOSE:To make it possible to display ventilation, drainage, and explosion-proof functions by the use of a common air vent by boring the air vent in a position facing the ground side in a larger diameter part of the distributor cap so that one end of the air hole is connected to the outside and the other end of the air hole is connected to an inside cavity. CONSTITUTION:In the opening end part 17 of a distributor cap 14 fitted to a distributor housing 1 is provided a larger diameter part 21 whose inside diameter is larger than that of a body part 14a and is larger than outer diameter of fitting part 19 of the distributor cap. And a cavity S is formed inside the distributor by the inside wall part of the larger diameter part 21 and one portion of the fitting part 19. Further, an air vent 27 is bored in the larger diameter part 21 for exhaust and drainage purposes in a position facing the ground side when the distributor is located horizontally to an internal combustion engine. The air vent 27 is constructed so that one end is connected to the outside of the distributor and the other end is connected to the cavity S, and is partly bent, forming a quenching construction. Thus, since the ventilation, drainage, and explosion-proof functions can be effectively displayed using a common air vent 27, the durability and reliability of the distributor can be greatly improved.

Title: Ink-jet head
Inventor: SAKURAI HISAYOSHI
IPC: B41J2/045
Filed: 1997-11-11
Abstract: PROBLEM TO BE SOLVED: To keep the constant discharge of ink droplets by forming grooves at least at one place of a surface opposite to the surface facing the pressure chamber of a laminated piezoelectric element which is located corresponding to the side wall of the ink pressure chamber. SOLUTION: When driving voltage is applied to an ink-jet head 1, a laminated piezoelectric element 5 is deformed in a shear mode between an individual driving electrode 21a and an individual electrode 21b and deformed in a unimorph mode between the individual electrode 21a and a common driving electrode 25. The piezoelectric element 5 is protruded toward an ink pressure chamber, and the ink pressure of ink pressure chamber increases, so that ink is discharged from a nozzle 13a. Since grooves 29 are formed on the upper surface of the piezoelectric element 5 to weaken connection with an adjoining ink pressure chamber, the deformation of a side wall 27 due to unimorph mode is almost prevented so that stable ink discharge performance can be obtained without causing problems of cross strokes.

Title: Optical disc apparatus
Inventor: HASHIMOTO MINORU
IPC: G11B7/085
Filed: 1990-11-16
Abstract: PURPOSE:To achieve a quick movement of an optical pickup by detecting whether rotation frequency of an optical disc is in an area near a resonance frequency of the optical pickup or not. CONSTITUTION:Upon the entry of an access mode, a system controller 6 examines whether the current position of an optical pickup (PU)5 is within a specified area using information from a position information detecting circuit 14 to judge whether the rotation frequency of a disc 3 is in an area near a resonance frequency of the PU5 or not. When it is in the area, the controller performs a track jump control of the PU5 with a focus tracking servo circuit 13 in operation. Otherwise, the controller stops the circuit 13 and performs an access control to move the PU5 fast with a feed motor drive circuit 12. Based on positional information of the circuit 14, this access control operation is repeated if the current position of the PU5 does not reach a desired track position and the access control ends when it reaches the desired track position. This enables the moving of the PU5 to the desired track position stably and quickly.

IPC: B21K21/08
Filed: 1997-11-11
Abstract: PROBLEM TO BE SOLVED: To improve bending strength by arranging a reinforcement, of which bending rigidity is high at a central part in the axial direction and of which bending rigidity is continuously reduced toward the edge so as to be nearly zero at the edge in the predetermined range continued to both edges in the axial direction. SOLUTION: A reinforcement 16 is provided with a solid bulkhead 18 at a central part in the axial direction.

Since this reinforcement 16 is arranged, high buckling performance can be obtained by the bulkhead 18 near the center position S of a main body part 12, and while the concentration of stress can be prevented by the thickness gradually reduced part 20 near the edges.
Patent JP-H01150296-A (JP)
Title: Signal detecting circuit
Inventor: SHIRAI MASAKI
IPC: G11C16/06
Filed: 1987-12-07
Abstract: PURPOSE:To attain accurate and rapid detection even if a signal on a bit line is small by changing a reference voltage generated on a dummy memory cell side reversely to the potential of a bit line on a reading side. CONSTITUTION:When an address change detecting circuit ACD detects a change in an address signal A, a control signal C to be turned to a low level only in an unstable period of potential VB on a common bit line CB is outputted and a switch MOSFET Q5 connected to a MOSFET Q4 in series is turned off. Consequently, current ID is allowed to flow only to a MOSFET Q3' in a dummy side current/voltage converter CVCZ. Thereby, a reference voltage Vr supplied from an inverter INV2 to a differential amplifier SA is stabilized at an intermediate potential between the high and low levels of a reading voltage VM. At the time of stabilizing the potential VB, the FET Q5 is turned on again and a part of the current ID is allowed to flow into the FET Q4 side to be driven by the voltage VM. Consequently, the reference voltage Vr is immediately transferred to the reverse level to the reading voltage VM.

As a result, the position command and the corresponding alarm are outputted to the outside, and the usability can be evaluated in a short period and correctly.

Filed: 1989-11-29
Abstract: PURPOSE: To facilitate maintenance work by forming a unit body by integrating a toner carrier and a toner passing means and constituting the unit body to be freely attachable/detachable to/from a device main body in the direction nearer to and away from a back electrode. CONSTITUTION: The unit body 10A is formed by integrating the toner carrier 1 and a control electrode 3 and constituted to be freely attachable/detachable to/from the device main body in the direction nearer to and away from the back electrode 2. Therefore, the inserting part of a recording paper is opened and the jam processing thereof is facilitated. Besides, since the unit body 10A is not pulled out in the direction not to be moved in parallel to the electrode 2 but to be pulled out in the direction away from the electrode 2, the electrode is prevented from being damaged because the jammed recording paper rubs the electrode 3. Moreover, since the electrode 3 is directly exposed when the unit body 10A is pulled out, it is easily cleaned and the clogging of an empty hole is also easily eliminated. Thus, the maintenance work for toner staining or jamming is facilitated.
