Title: Fine alpha-alumina ultrafiltration membrane and production thereof
Inventor: ROBAATO EI HEI
IPC: C04B41/87
Filed: 1988-12-09
Abstract: PURPOSE: To obtain an ultrafiltration membrane having an alpha alumina sepn. layer having an average pore diameter of <=35 nm by applying an alumina hydrate gel dispersed with finely divided crystalline seed particles on a porous support and drying the coating, then heating the same at <1300 deg.C. CONSTITUTION: The alumina hydrate gel dispersed (about 0.05 to 1 wt.%) with the finely divided crystalline seed particles (a specification surface area of >=35 m<2> /g is preferable) is applied on the porous support, such as tubular microfilter, of alpha alumina. The coating is then dried and thereafter the dried gel is heated at <1300 deg.C for the time sufficient for converting the gel to the alpha alumina and to bond the same onto the support. As a result, the novel ultrafiltration membrane having the sepn. layer of which at least >=60 vol.% consists of the alpha alumina and which has the pore size of <=35 nm is obtd. The temp. necessary for conversion to the alpha alumina is higher and the pore size is larger if the seed crystals are not added.

Title: Communications equipment and storage medium thereof
Inventor: ISAKI TAKESHI
IPC: H04W72/04
Filed: 1998-11-02
Abstract: PROBLEM TO BE SOLVED: To make the operation of a slave set side as quick as possible at the time of calling, when communication equipment is used in a master-slave form. SOLUTION: A CPU decides whether or not a seizing signal is received (S10) and decides whether or not a calling signal is received (S18), after receiving the seizing signal when it is called from the opposite calling party. In this case, the CPU acquires an identification number (S13), by receiving an ID signal within a prescribed period from receiving the seizing signal until receiving the calling signal, and immediately after that, establishes a channel for exchanging a communication signal with a slave unit (S17 and S28). After the channel is established, the CPU then transmits the communication signal to the slave unit through the already established channel (S19) by receiving the calling signal following the seizing signal and the ID signal.

Title: Pump for ink jet printer
Inventor: SUGIMURA SHIGEO
IPC: B41J2/185
Filed: 1990-11-17
Abstract: PURPOSE:To seal the first and the second piston and allow a specified amount of ink under a specified pressure to flow into a printing head by applying a pressure force to the first piston manually through an elastic member. CONSTITUTION:If ink discharge becomes inferior in a printing head 11 due to the intrusion of dust or air bubbles, the shaft part 2b of the first piston 2 is pushed through a rubber stopper 6 with the help of an operating shaft 12 or manually. As a result, a sealing part 2e comes in contact with the inclined part 3d of the second picton 3 to realize a sealed state. At the same time, the second piston 3 moves in an arrow B direction with the first picton 2. Ink is sealed and pressurized by the internal diameter of a main pump system 1 and the sliding part 3b of the second piston 3 following said movement, and an ink amount proportional to the movement value of the second piston 3 is sent to the printing head 11. Next, if a pressure force acting on the first picton 2 through the rubber stopper 6 is eliminated, the first piston 2 moves in an arrow C direction due to a restoration force gnerated by a piston return spring 5, and the spherical protrusion 3a of the second piston comes in contact with a piston fixing member 4, resulting in the movement of the second piston 3 in the arrow C direction.

IPC: H02K3/34
Filed: 1991-11-27
Abstract: PURPOSE:To prevent a wedge insulating paper from moving due to vibration by projecting the wedge insulating paper at bore side slot from the end face of stator core upto the coil end and then bundling the wedge insulating paper, together with the coil end, by means of a bundling paper. CONSTITUTION:Wedge insulating papers 21-28, fit respectively in slots 12-19, are projected from a stator substantially upto a coil end formed by stator windings 11-14 and stator windings 15-18. Consequently, when the wedge insulating papers 21-28 are inserted unto the slots, insertion is completed when the leading end of an inserter reaches the height of the coil end. Subsequently, the wedge insulating papers 21-28 are bundled together with the coil end by means of bundling threads 41-47 at the time of shaping of coil end. Since the wedge insulating papers are secured to the coil end by means of the bundling threads, the wedge insulating papers are prevented from being shifted or removed due to vibration at the time of starting or driving of motor.

Abstract: PURPOSE:To stabilize the reproduction of a magnetic tape after copy preventing processing by inhibiting or making it ineffective the count of a horizontal synchronizing signal during a copy guard pulse CGP period and providing an on- screen display stabilizing circuit masking the CGP substantially giving adverse effect onto the positioning of on-screen display. CONSTITUTION:The on-screen display stabilizing circuit 5 consists of a low pass filter circuit 6, a waveform shaping circuit 7, and a delay circuit 8 such as a rear edge delay type monostable multivibrator. Since the on-screen display stabilizing circuit 5 is constituted such that the count of the horizontal synchronizing signal is inhibited or made ineffective and the CGP giving adverse effect onto the positioning of the on-screen display is masked substantially, disadvantages such as the deviation of the on-screen display position due to the effect of the CGP or vertical movement of the on-screen display in the field period are prevented surely.

The gap keeping protruded pieces 4 have the layout and height that the face of the heat ray shielding film 3 is kept in no contact with a horizontal mount plane. When the door 1 is removed from the refrigerating show case and stacked on the floor surface, a gap is formed between the face of the hot ray shielding film 3 and the floor by the existence of the gap keeping protruded pieces 4, and the damage of the hot ray shielding film 3 can be prevented.

Title: Method for inspecting conduction of wire harness and conduction inspection device
Inventor: SASAI OSAMU
IPC: G01R31/02
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To surely detect also an abnormal deformation of a terminal metal fitting at low costs, by inserting a contact element having a switch part operating when a predetermined pressing force is applied into a main body of a terminal. SOLUTION: When an inspection part 43 is brought near to a connector, a contact pin 61 of a contact probe 20 is inserted into a terminal metal fitting. At this time, if a tongue element of the terminal metal fitting is not deformed and held in a state wherein a predetermined butting force to hold a male terminal metal fitting is obtained, the contact pin 61 receives a predetermined pressing force in an axial direction when an entering part 68 enters the terminal metal fitting. As a result,, the contact pin 61 is slid against an urging force of a spring 73, and a switch part 74 is turned ON.  On the other hand, if the tongue element is deformed, etc., and therefore the butting force to hold the male terminal metal fitting cannot be obtained, the contact pin 61 receives merely a small pressing force even when the entering part 68 is inserted, whereby the contact pin 61 and an electrode pin 62 are not brought in touch with each other. That is, the switch part 74 is not turned ON, and an inspection result is a conduction failure.

Abstract: PURPOSE:To obtain an AlN resistant to chipping and cracking in laser-working of AlN by adding Dy2O3 to AlN raw material and sintering in a reducing atmosphere, thereby segregating a vitreous phase on the surface of AlN. CONSTITUTION:Aluminum nitride raw material is added with 2.7-3.3wt.% of Dy2O3 and sintered in a reducing atmosphere at 1750-1875 deg.C to effect the segregation of vitreous phase composed of Dy2O3 added to the aluminum nitride raw material on the surface of the aluminum nitride and obtain the objective aluminum nitride. Since the vitreous phase composed of Dy2O3 in AlN is segregated on the surface of the aluminum nitride, the AlN can be worked by laser- working process without generating the defects such as chipping and cracking which are suspected to be caused by the void in the AlN.
