Title: Filter for civil engineering works and draining material using it
Inventor: KUSAKA TATSURO
IPC: E02D17/20
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To provide a filter for civil engineering works and a water draining material using filter, with which it is practicable to allow passage of a large quantity of water in a short time and prevent clogging through preclusion of sand and earth, small stones, etc., from flowing in. SOLUTION: A sheet 2 is furnished with holes 3 having a diameter between 1 and 10 mm in such an arrangement that the rate of hole opening ranges from 5 to 20%, more preferably from 7 to 15% in uniform dispersion. In the initial period of water passage, a small amount of fine earth grains and organic substance are allowed to flow out from holes 3 having greater diameters and a bridging layer of earth grains having comparatively greater diameters is formed on the surface of a filter 1 for civil engineering works, and because of passing through the bridging layer thereafter, no clogging with fine earth grains will occur nor a secondary clogging resulting from generation of bacteria.

Title: Rotary head type magnetic recording and reproducing device
Inventor: YOSHIDA RITSUO
IPC: G11B5/024
Filed: 1985-07-01
Abstract: PURPOSE:To attain sufficient erasing with simple constitution by fitting a head to be exclusively used for erasing to a rotary drum on which four magnetic heads are arranged with equal intervals so that the erasing head has a level difference from the magnetic heads. CONSTITUTION:If it is supposed that a tape 16 is carried so that a recording track is formed on the upper part of the rotary drum 15, the difference in level between the recording/reproducing heads 11-14 and the lower edge of the erasing head 17 will be found out. A locus to be easily erased by the erasing head 17 out of locuses of the magnetic heads 11-14 is the locus of the magnetic head 12 arranged on the nearest position prior to the erasing head 17. Namely, when the erasing head 17 is to be arranged immediately after the head 12, the erasing head 17 may be arranged on the upper position of the magnetic head 12 with TP height difference. To minimize the level difference, the erasing head 17 may be arranged immediately before the magnetic head 11 and the level difference required at that time is 2/3TP=TP-1/3TP or more. Consequently, a low frequency conversion chrominance signal can be sufficiently erased with a simple constitution.

Abstract: PURPOSE:To prevent interference onto an adjacent channel without a distorted output signal even at an initial rising point when an input signal is applied by quickening a reply speed of a loop time constant of a time constant controller. CONSTITUTION:A signal subject to level control by a frequency conversion section 8 is inputted to an amplifier section 19 and an output signal of a gain controller 13 controlling a variable gain amplifier 10 is given to a time constant controller 14 and an amplifier 20 comprising a resistor 15, capacitors 16, 17 and a relay based on an output of a level detector 11 so that an output of the variable gain amplifier 10 is constant. On the other hand, when an output signal of a level detector 9 connecting to the input of the variable gain amplifier 10 reaches a preset level or below, a contact of the relay 18 by a changeover controller 12 is opened to disconnect the capacitor 17 deciding the loop time constant from the circuit thereby quickening the reply speed of level control.

Title: Manufacturing method for commutator groove
Inventor: TOMITA MINORU
IPC: H02K13/00
Filed: 1994-05-31
Abstract: PURPOSE:To reduce an error to half as compared with a conventional one in a step for manufacturing a commutator groove, by adding a mean value of differences between a theoretical value and a segment groove pitch measured by turning a commutator at each groove center when a base manufacturing reference point is measured. CONSTITUTION:A central point P0 in one segment groove is used as a temporary reference point of cutting. An adjacent central point P1 is measured by turning a commutator and a length from the reference point P0 to the central point P1 is calculated. A difference DELTAP1 between the length anal a theoretical value (360 deg.,/n; n is the number of segments) is calculated. Then, central point P1, P2..., Pn in segment grooves are each measured by turning the commutator one revolution. After each length from the temporary reference point P0 is sought, differences DELTAP1, DELTAP2..., DELTAPn from each theoretical value are calculated. A mean value is calculated by dividing the total of differences by the number (n) of commutator segments. A real cutting reference value is obtained by adding the mean value to the temporary reference value P0.

Filed: 1999-05-24
Abstract: PROBLEM TO BE SOLVED: To heat even the inside of food to be cooked not to burn its front surface and to permit fat exuded from the food to be cooked to get away when the food contains fat by providing many non-continuous projections on the front surface of a planar main body. SOLUTION: A grill plate 1 is heated from a rear surface side, food to be cooked is placed on the front surface of the planar main body 2 of the plate 1. When the food is grilled, it is supported by the many projections 21 formed on the front surface of the main body 2 so that parts between the food and the parts between the mutual projections in the main body 2 become gaps. Air heated by the plate 1 exists in the gaps and, then, the food is grilled while preventing its burning on its front surface with heated air. Besides, fat drops onto the parts between the projections 21 on the main body 2 when the fat is exuded from the food so that it is no steeped in the fat and the fat is efficiently removed.

Title: Sintered compact for tool and its production
Inventor: TSUNODA HIDEO
IPC: C04B35/10
Filed: 1989-06-07
Abstract: PURPOSE:To provide a sintered compact for tool capable of low-temp. sintering and causing neither breaking nor abnormal wear of tip at the time of high-speed matching by adding specific amounts of monoclinic ZrO2 having specific grain size to Al2O3 in which SiC whiskers and ZrO2 fibers are incorporated. CONSTITUTION:This sintered compact for tool is produced by sintering a powder mixture which consists of 1-10wt.% monoclinic ZrO2 of <=1000Angstrom  average grain size and 90-99wt.% Al2O3 containing 5-20vol.% SiC whiskers or/and ZrO2 fibers. Since ZrO2 enables the low-temp. sintering of Al2O3 and is uniformly dispersed in the surface of Al2O3 grains, and further, at the time of sintering, ZrO2 absorbs impurity components in Al2O3 and also forms solid solutions together with Al2O3, grain boundaries are firmly bound. When the average grain size of ZrO2 is >=1000Angstrom , uniform dispersion into Al2O3 cannot be attained, and, as to the additive quantity of ZrO2, grain boundary binding power is insufficient when it is <=1% and, on the other hand, the effect caused by increased amount of ZrO2 cannot be attained when it exceeds 10%. SiC whiskers and ZrO2 fibers are added principally in order to increase the toughness of the sintered compact.

Abstract: PROBLEM TO BE SOLVED: To provide a high accuracy semiconductor angular velocity sensor in which the leak to the sensor output by a drive signals is eliminated to avoid the zero point drift and a manufacturing method thereof. SOLUTION: A frame 2 which is separated upward from a board 90 and swingable in direction Y and a plumb 3 swingable in the direction Y, together with the frame 2 and displaceable in direction X are provided, insulators 29 are formed on the frame 2 to section into semiconductor parts 21-24, comb-like electrodes 27 are provided on the semiconductor parts 22, 23, so that the semiconductor parts 21, 24 may be conductive with the plumb 3, and a comb-like electrode 31 is provided on the plumb 3. When only the oscillation drive is applied to the frame 2, the plumb 3 and frame 2, i.e., the comb-like electrodes 31, 27 oscillate together and hence it never becomes a leak signal to the capacitance detection.  When an angular velocity is applied, the plumb 3 shifts in the direction X to the frame 2 due to the Coriolis force, and hence the angular velocity can be detected from the change of the capacitance.
