Title: Disk device
Inventor: WAKUTA HIROSHI
IPC: G11B5/596
Filed: 1998-10-14
Abstract: PROBLEM TO BE SOLVED: To highly accurately detect a head position by correcting and controlling a reference middle value based on a correction value for reducing or eliminating an offset quantity by detecting the middle value of the maximum and minimum values of an output detected when a seeking operation is carried out, the preset reference middle value and the offset quantity. SOLUTION: Integral values (a) and (b) obtained by integrating the levels of the detected outputs of respective A and B phases by the time from a reference middle value immediately after the detected outputs are obtained from a linear sensor 8 are obtained for each track. In the midway of a seeking operation, the reference middle value set for each track is corrected by using the integral values (a) and (b). The corrected reference middle value of the A phase obtained by an operation is  reference middle value of A phase+a×k), and the corrected middle reference value of the B phase is  reference middle value of B phase+b×k). The code (k) denotes a coefficient for correction, meaning a correction gain when correction is made by a CPU7. The coefficient (k) is set to a correction gain enabling a DC offset quantity to be eliminated by 70 to 80%.

Title: Automatic hot water feeding device
Inventor: HIRATA KUNIO
IPC: F24D17/00
Filed: 1990-10-29
Abstract: PURPOSE:To keep temperature in a bath tub at a desired value by a method wherein control is effected such that when an arrival temperature is set and hot water is poured, the temperature of hot water fed in a hot water tank is higher than a set temperature according to a difference between a set temperature and the temperature of hot water in the hot water tank detected by a sensor. CONSTITUTION:A difference  T between a set arrival temperate T1 and a hot water temperature T2 in a hot water tank detected by a sensor 14 is calculated. When  T exceeds a x1 deg.C, through control of the mixing ratio of a mixing valve, hot water having temperature obtained by adding alpha1 deg.C to the set arrival temperature T1 is poured. When  T is below x1 deg.C,  T exceeds x2 deg.C, the mixing ratio of the mixing valve is controlled, and hot water having temperature obtained by adding alpha2 deg.C to the set arrival temperature T1 is poured. When  T is below x2 deg.C, a process is progressed to a stop S11, the mixing ratio of the mixing valve is controlled and hot water having temperature obtained by adding alpha3 deg.C to the set arrival temperature T1 is poured. Namely, through the feed of hot water, having temperature higher than the set temperature according to the magnitude of the temperature difference T, to the hot water tank, hot water is poured so that the hot water temperature T1 in the hot water tank attains the arrival temperature T2.

While the member 3 is kept rotated at the prescribed rotating speed, gaseous H2, O2, SiCl4 and Ar are supplied to the burner and the SiCl4 is cracked in the combustion flame 2 to form the fine glass particles which are deposited on the member 3. The gaseous He is simultaneously injected from the nozzle 5 to cool the deposited glass. The deposited part A under cooling is moved to the flame 2 side and the fine glass particles are deposited thereon as the member 3 rotates. The burner 1 and the nozzle 5 are successively moved and a porous preform 4 which is a base material is thus formed.

Title: Cylinder for injection molding machine
Inventor: FUJIOKA OSAMU
IPC: B29C45/48
Filed: 1995-10-17
Abstract: PROBLEM TO BE SOLVED: To provide the cylinder for an injection molding machine which makes it possible to stabilize the metering operation of the drawing or conveying of a resin pellet. SOLUTION: The inner wall of a cylinder 5 is divided into two or more blocks in the axial direction of the cylinder, and the surface roughness of the inner wall of each of the divided blocks is so decided that the metering and kneading operation can be smoothly conducted in response to the types of the resin pair to be used. For example, in the case of attempting to enhance the efficiency of resin feeding, the inner wall of the cylinder 5 is divided into two blocks 5e, 5f, and only the surface roughness of the side of the block 5e of the side including a supply part 5c is roughly finished.  Since a resin pellet can be maintained in the state that the frictional resistance between the wall 5e and the resin pellet is always larger than that between a screw and the pellet, the conveying and drawing of the pellet by the part 5c are effectively secured, the predetermined metering time is stabilized to make it possible to prevent the molding failure due to the thermal decomposition of the resin or generation of carbide.

Title: Method of molding rim product having recessed and projected pattern
Inventor: NODA HOZUMI
IPC: B29L31/58
Filed: 1988-11-21
Abstract: PURPOSE:To certainly mold a reaction injection molding(RIM) product having recessed and projected pattern with no voids by a method wherein RIM raw material is injected in the cavity of a mold under the condition that the interval between a first mold member and a sliding mold member is set to be narrower than the dimension of the thickness of the recessed and projected pattern of the RIM product and, after that, said interval is widened to the dimension corresponding to that of the thickness of the recessed and projected pattern. CONSTITUTION:At the injection stage of RIM raw material A', a sliding mold member 6 is projected to a cavity mold 2 side by the spring forces of a plurality of coiled springs 7 so as to narrow the gap of a cavity 3 (or an interval between the front surface shape part 2a of the cavity mold 2 and the rear surface shape part 6a of the sliding mold member 6). On the other hand, after the injection of the RIM raw material A', the sliding mold member 1 is retreated by the forming pressure of the RIM raw material against the spring forces of the respective coiled springs 7 so as to widen the interval of the cavity 3 to the dimension corresponding to that of the thickness of the respective recessed and projected pattern of a spoiler. Thus, air accumulated to the corner side of the cavity 3 is gone, resulting in allowing to certainly mold the spoiler, each recessed and projected pattern of which has no resin-starved area.

Title: Wiring board, liquid crystal display device and electronic equipment using it
Inventor: MURAMATSU EIJI
IPC: H05K1/02
Filed: 1998-10-15
Abstract: PROBLEM TO BE SOLVED: To provide a wiring board which is enhanced in connection reliability by a method wherein a force induced by a thermal expansion coefficient difference between the wiring board and a mounted part and applied to a joint between them is lessened. SOLUTION: A wiring board 10 is equipped with a resin layer 14 and wiring layers 18 and 20 formed on both the surfaces of the resin layer 14. No wiring layer is formed on the rear surface of the board 10 corresponding to its front region where an IC chip 30 is mounted. The resin layer 14 is formed thinner in a region where the IC chip chip 30 is mounted than in the other region. As no wiring layer is formed on the rear region of the board opposed to its front region where a mounting part is mounted, a distortion of the wiring board 10 caused by a thermal expansion difference between the resin layer and the wiring layer attendant on a temperature change after a mounted part is mounted is prevented from occurring in a part mounting region.  Therefore, a force that is induced by the distortion caused by a temperature change and applied to a joint of a mounting part is lessened, so that a mounting part can be improved in joint reliability.
