Title: Rotary four-way valve
Inventor: ESUMI HAJIME

Filed: 2000-03-14
Abstract: PROBLEM TO BE SOLVED: To solve the problems of a rotary four-way valve of an outdoor machine of, for example, an air conditioner that a gear housing is corroded if foreign matter such as water and dust enters a recessed part and the vibration occurs if the foreign matter is caught in a clearance, thereby damaging the housing, by storing a part of a non-contact drive type motor in the recessed part on an outer face of the gear housing by providing the clearance.

Title: Enclosure for account adjusting device
Inventor: HAYAKAWA YOSHIKAGE
IPC: E05B65/00
Filed: 2000-03-15
Abstract: PROBLEM TO BE SOLVED: To improve the burglarproof effect of an account adjusting device. SOLUTION: The door of this enclosure is attached to the enclosure main body in such a way that the door is opened and closed around a shaft provided in parallel with a prewscribed surface of the enclosure body. When the door is closed, the engaged section formed of the enclosure body and door does not become a target of destruction, because the inclined surfaces of the engaged section closely adhere to each other and the insertion of a craw bar, etc., between the inclined surfaces is difficult. When the door is opened, the inclined surfaces are separated from each other. Since the hinges of the door are hardly visible from the outside, the hinges hardly become the target of destroying activities. The door is constituted in a dual structure of external and internal walls and hole boring work from the outside takes time.  Even when a thief gouges out a cylinder section which conducts the locking and unlocking of a lock, a handle races and he is not able to move a locking mechanism. In addition, when he tries to remove the lock itself by destruction, the link of the locking mechanism falls off and he is not able to release a latch. Since the locking mechanism is fitted in the door after its whole body is housed in a case, the mechanism is not visible even when a hole is bored into the door and destroying activities require long time and much labor.

Title: Mass flow rate controller
Inventor: TANAKA MAKOTO
IPC: G05D7/06
Filed: 2000-03-16
Abstract: PROBLEM TO BE SOLVED: To provide a mass flow rate controller which enables controlling of a flow rate at a higher accuracy with a limited effect of zero point deviation in a small flow rate region by maintaining the control of a flow rate to a certain extent in a large flow rate region. SOLUTION: In the mass flow rate controller, a fluid flows being branched off at a specified shunt ratio to a bypass passages 18' and a sensor passage 20 wound with heating resistance wires 24A and 24B forming a part of a bridge circuit 22, the moving of heat caused as the fluid flows through the sensor passage is captured as imbalance of the bridge circuit to determine the overall flow rate of the fluid as sensor output based on which the overall flow rate of the fluid is controlled by a flow control valve. The conversion factor that is so determined by the ratio of the flow rate of a nitrogen gas and an SF6 gas to make the sensor output equal is so arranged to give a difference of 8% or more when the set flow rate is 30% of the full scale as compared with that when the set flow rate is 100% of the full scale.  Thus, the control of the flow rate can be maintained at a higher accuracy to a certain extent in a large flow rate region thereby enabling the control of the flow rate at a higher accuracy and with a limited effect of a zero point deviation in a small flow rate region.

Title: Semiconductor device
Inventor: MASE AKIRA
IPC: G02F1/1368
Filed: 2000-03-21
Abstract: PROBLEM TO BE SOLVED: To cheaply obtain at a low price a liquid crystal device with the reduced capacity and light-weight by forming a switching element TFT for an optical shutter and a driver TFT for driving the liquid crystal device on the same substrate. SOLUTION: In a drive circuit arranged around a substrate, although it is most preferable to form all the components on the same substrate, however, forming at least a block closed to an output terminal, i.e., a block circuit part closed to an optical shutter on the substrate also has an effect to fulley reduce the capacity and weight. Also, in this case, the degree of integration of an IC chip equivalent to the other circuit parts can be suppressed, and as a result, the cost of the IC chip can be restrained. In this way, by using a laser beam whose cross section is made to be linear shape by an optical system, doping an high-resistance amorphous silicon film corresponding to a plurality of transistors with phosphorus, slicing and facilitating crystallization of the high resistant amorphous silicon film are successively performed.  Thus, leakage current can be suppressed to be very low level.
