Title: Electromagnetic solenoid
Inventor: YAMAGAMI ICHIROU
IPC: H01F7/16
Filed: 1983-11-18
Abstract: PURPOSE:To attenuate noises generated by impingement between a movable iron core and a core receiver, by providing a vibration damper between a yoke and a coil. CONSTITUTION:A solenoid is provided with a vibration damper 10 between the inner face of a first yoke 2 and a coil 5. For example, after this vibration damper is inserted between the coil 5 and the first yoke 2, the first and second yokes 2 and 3 are caulked so as to form a solenoid. In such a manner, even when the noises generated by the impingement between a movable iron core 1 and a core receiver 4 is transmitted to the first yoke 2, the first yoke is effectively prevented from vibration by the vibration damper 10. Accordingly, the impingement noises can be prevented from amplifying, and as a result, undesired noises generated by sound equipments or the like can be attenuated.

IPC: B04C5/103
Filed: 1997-07-28
Abstract: PROBLEM TO BE SOLVED: To improve the separated oil recovery effect of a cyclone-type oil separator with a compact structure. SOLUTION: The oil contained in the blow-by gas out of the blow-by gas introduced into a cyclone 1 and whirled up from an inlet 101 is affected by a centrifugal force from the spiral flow formed by the blow-by gas, sent toward the periphery along the ceiling surface 3a, recovered by an auxiliary recovery passage 7 having an opening 104 in the peripheral wall 2 of the cyclone 1 directly velow the ceiling 3, recovered from the recovery port 103 at the lower end of the cyclone 1 and joined to the separated oil. As a result, the oil is not retained on the ceiling surface 30, and the oil is prevented from being contained in the blow-by gas discharged from an outlet 102.

Title: Determination system for azimuth and position of unmanned carriage
Inventor: ITO JUNICHI
IPC: G05D1/02
Filed: 1992-07-24
Abstract: PURPOSE:To flexibly select a travel route and a travel pattern by using a bar code which is formed of a light reflecting body and has coordinates recorded as a mark and using a bar code reader as a mark sensor. CONSTITUTION:The output dthetas/dt of a rate sensor 1 is corrected with a bias error DELTAdtheta/dt outputted by a rate sensor correcting circuit 2. Azimuth acceleration dtheta/dt is found and integrated by an integration circuit 4 to obtain an azimuth angle theta. A speed V is calculated from the product of the rotating speed n of a rear wheel 5a and a scale factor A and integrated by a position detecting circuit 8 to obtain a coordinate position. The coordinates of the mark formed on a travel path are recorded as the bar code. Mark sensors Q1-Q7 read the coordinates each time the mark is passed during the travel and an updating circuit 9 calculates the real coordinate position and azimuth. Those coordinate position and azimuth are used as initial values of the integration of the speed V and the integration of the azimuth acceleration dtheta/dt. Consequently, a flexible guidance becomes possible.

Title: Folding replaceable blade saw
Inventor: BABA KOICHI
IPC: B27B21/04
Filed: 1998-08-03
Abstract: PROBLEM TO BE SOLVED: To enable a replaceable blade to be attached and detached and rotated and inserted into a narrowly spaced blade supporting part to retain a blade base firmly by forming the narrowly spaced blade support part which matches with the thickness of the blade, along the front end part of a fitting metal. SOLUTION: When a replacement blade 1 is mounted, the blade 1 is rotatable around the base part, and stopped at a place by a rotation resistance following the clamping of the replacement blade 1 by a recessed part. When the saw is to be used, the latching claw 221 of a lock 23 is latched onto a locking recessed part 12 in the back part of the replacement blade 1. Thus the blade 1 is prevented from being rotated in the storing direction. When storing the blade 1, the lock 23 is manipulated to disengage the claw 231 from a latching state and the blade is rotated in the storing direction. In addition, in a use state, the base of the blade 1 is fitted into a support part 223 to support the blade 1. Consequently the bade 1 is clamped at the position of the peripheral part of a rotary shaft and the position of the support part 223, and the base of the blade 1 is firmly retained.

Title: Semiconductor device
Inventor: SUZUKI YUJI
IPC: H01L29/786
Filed: 1995-08-28
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor device which restrains an on-resistance from being increased due to a high breakdown strength by a method wherein an impurity concentration down to a prescribed depth from the surface of a semiconductor substrate is made higher than an impurity concentration in a part which is deeper than the depth. SOLUTION: In an LDMOSFET 1 as a semiconductor device, a source region 5, a drain region 6 and a p-type well region 7 are formed inside a semiconductor substrate 2 which is installed on the surface of a support substrate 3 via an oxide film 4. An impurity concentration down to a depth of about 5μm in the depth direction from the surface of the semiconductor substrate 2 is made higher than an impurity concentration in a part which is deeper than the depth. Thereby, since an on-state current which flows to an n-channel from the drain region 6 flows uniformly only to a region in which an impurity concentration is high, an on-resistance can be made nearly constant irrespective of the thickness of the semiconductor substrate 2.  Consequently, even when the thickness of the semiconductor substrate 2 is made thick due to a high breakdown strength, it is possible to restrain the on-resistance from being increased.
