Title: Hot water feeding method
Inventor: KATO TATSUO
IPC: F24D17/00
Filed: 1988-11-28
Abstract: PURPOSE:To eliminate an installation of an over-heating prevention device, an empty heating prevention device, a short circuit breaker, an over-pressure prevention device and an over-pressure relief value by a method wherein hot water from a hot water feeder is accumulated in a vacuum container and the hot water is fed out through a plug. CONSTITUTION:As a plug 3 is rotated, a hot water feeder 1 is operated, water is fed from a water feeding pipe 13, the water is changed into a hot water, the hot water is mixed with water in a water feeding pipe 12 by a mixing valve 10 through each of a hot water feeding pipe 8, a vacuum tank 15 and a hot water feeding pipe 11, respectively, and then the hot water is fed out through a plug 3. Hot water accumulated in the hot water feeding pipe 8 is arranged outside a housing normally until the plug 3 is opened, the hot water is cooled by the surrounding atmosphere. The hot water 5 within the tank 15 installed within a wash basin is normally kept at its hot temperature due to a high thermal insulating characteristic of a vacuum space 15c. Accordingly, when the plug 3 is opened, a hot water of low temperature is mixed with the hot water 5 and then fed out through the plug 3. The hot water feeding pipe 11 is short in length and the hot water of low temperature is low in its volume, so that the hot water 5 is fed out immediately after the plug 3 is opened.

Title: Current inverting circuit
Inventor: HIKITA JUNICHI
IPC: G05F3/26
Filed: 1990-11-05
Abstract: PURPOSE:To perform the current inverting operation even at the time of reduc ing the voltage of a battery by leading a current from bases of first and second transistors Trs to the pair of Trs in accordance with the current on the collector side of the first Tr to reduce the minimum operating voltage. CONSTITUTION:A feedback loop is formed by a pair of Trs 30a and 30b in a current inverting circuit, and currents flowing to Trs 32 and 28b are balanced, and a constant current I1 is led to a Tr 50 from the side of a line 23 and is taken out from an output terminal 54. When the current amplification factor of Trs 32, 20a, 28a, 20b, and 28b is denmoted as beta, relations between the con stant current I1 and currents I2, I3, I4, and I5 are expressed with I4=I5/beta, I3=I4/beta, I2=I3/beta, and I5=I1/beta<4>. Consequently, the base current flowing to the Tr 20a is 1/beta<4> times as large as the constant current I1, and the voltage between the emitter and the collector of the Tr 20a is considerably reduced. Therefore, the minimum operating voltage of the current inverting circuit is reduced, and the current inverting operation of high reliability is realized with a low operat ing voltage.

Abstract: PROBLEM TO BE SOLVED: To reduce a variation of the resin density of molten resin by continuing pressure control to a screw at the termination of a metering process in a state where rotation of the screw is stopped or in a almost stopped condition. SOLUTION: When a pressure value applied on a screw detected by a load cell 10 has reached a set valve, an injection servomotor 6 is controlled for its rotation driving by a command from a pressure feedback controller 13b in order to be converted into the axial movement of the screw by a rotation to linear movement conversion mechanism 8, and thereafter the screw is permitted to start backward movement. During the period subsequent to this, the servomotor 6 is controlled in its normal-reverse rotation driving control or stop control through a pressure feedback controller 13b so that the pressure value applied on the screw detected by the load cell 10 comes in accordance with a set value, and the screw 2 is put into a reciprocal movement or stopped to control the pressure of resin.

Title: Device for applying powdery heat insulating material to inside surface of injection sleeve
Inventor: AKASE MAKOTO
IPC: B22D17/20
Filed: 1992-11-11
Abstract: PURPOSE:To automatically judge the state of applying a powdery heat insulating material to the inside surface of an injection sleeve and to prevent the generation of a defective product by the fall of a molten metal temp. and the generation of galling of a plunger tip by installing a thermocouple to the outer side in the lower part of the pouring port of the injection sleeve. CONSTITUTION:The thermocouple 5 is installed to the outer side in the lower part of an injection port 4 of the injection sleeve 2. The thermocouple 5 is used to monitor the temp. of the injection sleeve 2 at all times and is connected via a cable 6 to a thermometer 7 and an alarm 8. In the mass casting, the temp. of the injection sleeve 2 stabilizes nearly at a specified temp. when the powdery heat insulating material is applied normally on the inside surface 2a of the injection sleeve 2 but if the application defect of the powdery heat insulating material arises, the heat of the molten metal poured from the pouring port is deprived of by the injection sleeve 2 and, therefore, the temp. of the injection sleeve rises sharply. The abrupt temp. rise of the injection sleeve 2 is detected by the thermocouple 5 and is judged to be the abnormality of the application. This abnormality is indicated on the thermometer 7 and simultaneously an alarm is emitted by the alarm 8.

Abstract: PURPOSE:To eliminate the possibility of giving external damages to other objects and to enable an operator to stably carry out operation by providing erecting walls along the outside circumferential edges in the thin parts for connecting temples so that the tips of the temples are covered and are prevented from projecting to the outside when the temples are folded. CONSTITUTION:Mounting parts 3 at one end of a rim B are thinly formed so that the rib B can be grasped. The erecting walls 4 join to each other to prevent projection of the connecting ends of the rim B to the outside when both are superposed on each other. The walls prevent the damage in a pocket particularly when the spectacles are housed in the pocket. The walls also prevent the external damages when the spectacles are housed in a container or at the time of an assembling operation, etc. The erecting walls 4 and the inside edges 4a thereof are so formed as to be adapted to the shapes of the rim B and the temples C; for example, said walls and edges are curved or bulged outward or only the inside edges 4a are tapered around the center of through-holes 5 for mounting and screw holes 6. The projection of the connecting ends of the temples C to the outside is, therefore, obviated and the possibility of giving the external damages to the other objects is eliminated. The safety operation is thus assured.
