Title: Non-contact type card
Inventor: MATSUKAWA KOICHI
IPC: G07B15/00
Filed: 1995-11-01
Abstract: PROBLEM TO BE SOLVED: To easily utilize a non-contact type card even by a wheelchair user by securing a long communication range by providing a one-side directive antenna capable of executing communication when its prescribed one side and a transmitter side face each other on the main body of the card. SOLUTION: On the side of a front surface 2 being one side of a main body 1 of card, a slot antenna 3 is embedded so as to be the same surface as the front surface 2. In the main body 1 of card, the side of front surface 2 provided with the slot antenna 3 has the directivity of radio wave. When only the side of front surface 2 confronts the antenna side of transmitter, communication is enabled between the main body 1 of card and the transmitter, and data are transferred between them. When directivity is provided only on the front surface 2 being one side of the main body 1 of card, almost twice communication range of that of conventional double side directivity can be secured. Thus, communication is enabled while putting a communication ticket in a pocket at a non- contact type automatic ticket examination machine, and also even the wheelchair user can utilize this card.

Title: Ceiling embedded type air conditioner
Inventor: TANAKA HIDESHI
IPC: F24F1/00
Filed: 1993-11-02
Abstract: PURPOSE:To maintain a pressure difference between an air intake port and an air exhaust port constant and to sufficiently cool a motor with air forcible circulation flow by providing the intake port at an upstream side of a fan rotor and providing the exhaust port at a side opposed position of the rotor. CONSTITUTION:Since a static pressure of an air exhaust port 7 when a fan rotor 3 is rotated is lower than that at an air intake port 6, part of the air flow at an upstream of the rotor 3 is sucked from the port 6 by its pressure difference thereby to generate a forcible circulation flow to the port 7 through a motor 11 in a cooling passage 13, thereby cooling the motor 11 by the circulation flow. In this case, since distributions of the static pressures in openings of the intake port 6 and the exhaust port are relatively constant, a pressure difference between the port 6 and the port 7 is stabilized, and since its pressure difference can satisfy necessary level, the circulation flow generated in the passage 13 can be sufficiently obtained as a necessary amount.

Filed: 1987-12-07
Abstract: PURPOSE:To contrive to increase the yield of semiconductor element by lessening the deflection of a blade and consequently narrowing the width of a kerf despite the increase of the plate thickness of a wafer by a method wherein cut grooves are made by sawing from both the sides of the wafer of semiconductor. CONSTITUTION:A wafer 1 of semiconductor is fixed onto a stage 2. Next, sawing blades 3 and 6 are respectively fixed to blade holders 4 and 7 so as to be rotated about spindle shafts 5 and 8 in order to saw the wafer 1 of semiconductor from its both sides for breaking and separating the wafer 1 along kerfs into respective chips. Accordingly, despite the the increase of the plate thickness of the wafer 1, the sum of the kerf losses of the respective sawing blades 3 and 6 can be checked smaller than the kerf loss of a single sawing blade. Furthermore, the lateral deflection of the blade becomes smaller, resulting in allowing to prevent the breakage accident of the sawing blade from occurring.

IPC: H02M7/48
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To make it possible to widely control the output of a self-exciting inverter. SOLUTION: In a series inverter, a normally-open switch 19 is provided in parallel with a control terminal of a switching element 13 for fetching power- supply power into a resonance circuit 14. An inductive signal of a feed-back winding 18 for taking out the driving signal is branched and delayed by 90 degrees using a phase shifter 32. A DC signal of 0 or 1 at a terminal 29 is multiplied by a multiplier 22 to control the amplitude. The multiplied output (e) is compared with a window comparator 34. When the multiplied output is in a range from a negative-side set voltage ES2 to a positive-side set voltage ES1 , a pulse (f) is generated, and the switch 19 is turned on during the pulse generation. Even when the amplitude of the output (e) from the multiplier 33 is large, a peek or nearby value of the driving signal (c) is applied to the switching element 13.  Then, the switching element 13 is turned on surely while the amplitude is narrow, and stable operation is realized even when the output current is made small.

Abstract: PROBLEM TO BE SOLVED: To improve responsiveness in usual braking when liquid pressure is in a normal condition and ensure operation of the brake when the liquid pressure drops. SOLUTION: When an accumulator(ACC) 46 is at a preset liquid pressure or more, a power room 36 for a liquid pressure booster 2 is communicated with wheel cylinders(WCYs) 58, 59 by a switch valve 64.

When the ACC 46 is at a preset liquid pressure or less, a liquid room chamber 47 for a master cylinder(MCY) 3 is communicated with the WCYs 58, 59 by the switch valve 64. During brake operation, MCY pressure which is generated by an input shaft 21 operating a MCY piston 53 via a power piston 10 is guided through the switch valve 64 into the WCYs 58, 59. Even when liquid pressure in the ACC is smaller than a preset pressure, operation of the brake is ensured.

Abstract: PURPOSE:To avoid deformation caused by high speed rotation by providing thick thickness parts at the parts, most subject to stress based on the centrifugal force of a filled medium at the rotating time, of a connecting part for connecting a small diameter part to a large diameter part. CONSTITUTION:A connecting part 4 connecting a small diameter part 2 and a large diameter part 3 to each other is curved inward, and grease is filled between a shaft 5 and the connecting part 4. Thick wall parts 9A, 9B larger in wall thickness than the other part are formed at two places of the connecting part 4, that is, a part near the large diameter part 3 and a part where the curve is almost finished from that part. These thick thickness parts 9A, 9B are the parts most subject to stress based on the centrifugal force of the grease at the rotating time of the shaft 5. The thick thickness parts 9A, 9B are not thereby liable to deform so as to restrain the connecting part 4 from being bent outward. Deformation caused by high speed rotation can be thereby avoided so as to attain the long service life of a product.
