Title: Catalytic dephosphorization
Inventor: IWAI NOBUYUKI
IPC: C02F1/58
Filed: 1983-02-18
Abstract: PURPOSE:To efficiently remove phosphoric acid while enhancing the power of a dephosphorizing agent, by circulating a liquid to be treated into a packed column packed with the dephosphorizing agent containing a phosphate mineral after being catalytically treated with an aqueous alkali solution in which an oxidizing agent is coexistent. CONSTITUTION:After a calcium agent is optionally added to raw water, from which floating substance is previously removed by the operation of pretreatment, in response to the concentration of a soluble phosphate in said raw water, a pH is adjusted to 6.0-11.0. Then, the raw water is introduced through an inflow pipe 1 for raw water into the upper part of a dephosphorizing column 2. The dephosphorizing column 2 is packed with a crushed phosphate mineral containing calcium phosphate as a catalytic dephosphorizing agent 3. The raw water flowing in contact with the catalytic dephosphorizing agent 3 is discharged through an outflow pipe 4. The catalytic dephosphorizing agent 3 in the column is continuously or intermittently introduced into a reaction tank 6 and catalytically treated by agitating it with an aqueous alkali solution, in which an oxidizing agent is coexistent, supplied from a tank 14 by an agitator 8.

Title: Superprecise fine adjustment device
Inventor: SUZUKI NOBUO
IPC: B23Q5/38
Filed: 1978-03-07
Abstract: PURPOSE: To accurately position the fine adjustment of a superprecise device by rocking a lever upon rotation of an eccentric cam to reciprocate a member by a contactor attached to the vicinity of a pivotal shaft of the lever.  
     CONSTITUTION: An eccentric cam 3 is rotated around a center O 1  by a motor to thereby rock a lever 5 around a pivotal shaft 11. Since a spindle contactor 6 is attached to the vicinity of the shaft 11 of the lever 5, the spindle 7 is reciprocated by contraction by the reverse lever action of the lever 5. The eccentric amount of the cam 3 is moved in infinitesimal amount to electrically control the motor to thereby obtain the infinitesimal displacement.

Title: Manufacture of prepreg
Inventor: YANO MASABUMI
IPC: H05K1/03
Filed: 1992-02-13
Abstract: PURPOSE:To reduce the splash quantity of phenol in a drying process at the time of manufacturing prepreg by the use of phenol resin varnish blended with polymeric solid phenolic resin. CONSTITUTION:To resol phenolic resin of about 35% tung oil modification quantity, about 20 pts. of polymeric solid phenolic resin (Bellpearl) of 2000 or more and 15000 or less weight average molecular weight is added at solid weight ratio, and then it is adjusted to be about 60% methanol resin for making varnish. After varnish is impregnated and coated on a paper foundation material, it is dried to obtain prepreg. The prepreg and adhesive-coated copper foil are put together, and subsequently subjected to heat, pressurization and lamination for obtaining single-sided copper-clad laminated board. The characteristics as a copper-clad laminated board are equal to those which employ varnish not containing polymeric weight solid phenolic resin therein. Like this, by adding polymeric solid phenol not containing unreacted phenol, since the rate of the unreacted phenol decreases, the splash quantity of phenol is lessened during the coat-drying period.

Title: Semiconductor die-bonding apparatus
Inventor: YAMAGUCHI YUKIO
IPC: H01L21/52
Filed: 1990-02-05
Abstract: PURPOSE:To cause no breaking nor cracking and to make an inclination difficult to occur in a pellet and island space by pressing a pellet against a lead frame, after the pellet is bonded to the lead frame, in a position different from the bonding position and through a pressing means different from the bonding means. CONSTITUTION:A carrier part 13 for the lead frame 5 feeds the frame by an island space. At the time of stopping the lead frame 5, further, the predetermined quantity of bonding agent is applied to an island part by a bonding agent-applying head 14. The bonding power of a bonding head 15 is for lightly conducting temporary bonding. Therefore, a pellet 1 is lightly and temporarily bonded onto the lead frame 5. A pressing means 9 applies a predetermined pressing force to the pellet 1 temporarily bonded by the bonding head part 15. That is, when the pellet 1 is carried into, the pressing means 9 descends to pressing-bond the fed pellet 1. This pressing head 91 has a flat underside to enable bonding the pellet 1 and lead frame 5 without inclining them. The title apparatus repeats this operation automatically, performs a die bond of high quality and high productivity and is especially effective for bonding of a large pellet.

Title: Control method of ignition timing in internal-combustion engine
Inventor: TAKEDA YUUJI
IPC: F02P5/15
Filed: 1983-02-18
Abstract: PURPOSE:To prevent the output of an engine from decreasing, by controlling a delaymost timing limit to be moved to an advance side at rapid acceleration, in the case of a device formed such that the ignition timing is not delayed exceeding the delaymost timing limit. CONSTITUTION:The ignition timing is obtained from an intake air quantity Q and an engine speed N. Deciding whether or not an engine is at rapid acceleration, if it is at the rapid acceleration, a delaymost timing limit is moved to the advance side. Comparing the ignition timing with the delaymost timing limit, if it is delayed from the delaymost timing limit, the ignition timing is controlled to the delaymost timing limit. In this way, an output of the engine is not decreased.

Abstract: PURPOSE:To prevent the generation of deterioration of the image forming performance of a focusing light transmission body or an uneven light quantity caused by a peeled covering layer by forming the covering layer on an end face part of each focusing optical transmission body so as to become almost the same shape as its end face shape. CONSTITUTION:With respect to a focusing optical transmission body array, circular holes 5a are allowed to coincide with each end face of a focusing optical transmission body 1 and a mask 5 is installed on both end face side respectively. Subsequently, TiO2 and SiO2 being vapor-depositing materials are brought to non-heating vapor- deposition alternately, and a multi-layer coating layer is formed in only the end face part of the focusing optical transmission body 1 corresponding to the circular hole 5a part of the mask 5. Since a covering layer 4 is formed by non-heating coating, coating can be executed exactly without causing a misalignment due to a thermal expansion of the circular holes 5a of the installed mask 5. As for the covering layer 4, almost all of coating is executed to the end face part of the focusing optical transmission body 1, and to the part of a holding member 2, coating is executed only a little, therefore, the adhesion is excellent, and also, there is scarcely possibility that the covering layer 4 of the part of the holding member 2 peels off.
