Title: Manufacture of large sized rain water pit
Inventor: HASEGAWA TADASHI
IPC: B29C45/53
Filed: 1998-06-22
Abstract: PROBLEM TO BE SOLVED: To economically carry out a small and medium quantity production under a small scale low pressure by a method wherein a synthetic resin molding material melt, which is stored in an accumulator and kept under a uniform molten state, is injected in a mold under an in-mold pressure within a specified range. SOLUTION: Under the state that a plunger takes its retreated position, the screw 10 of a plunger 2 is rotated for charging a synthetic resin molding material 23 through a hopper 6. Next, the synthetic resin molding material 23 under being melted is fed forward in the cylinder 9 of the plunger 2 so as to be discharged through the tip of the cylinder 9 and stored in an accumulator 3. Then, after the synthetic resin molding material melt 24 fills the accumulator 3, the plunger 2 is advanced, resulting in injecting the melt 24 by one shot in a mold 5.  In this case, when an injection is carried out by a low in-mold pressure of 50-300 kgf/cm2 under the state that the molten state of the melt 24 in the accumulator 3 and that of the melt during an injection are kept uniformly, the residual stress within a molding becomes very small, resulting in improving the physical properties of the molding.

Title: Overdischarge protector device for battery pack
Inventor: YAMASHITA TAKASHI
IPC: H02H7/18
Filed: 1998-06-22
Abstract: PROBLEM TO BE SOLVED: To provide an overdischarge protector device for a battery pack capable of improving reliability of overdischarge judgment in the battery pack. SOLUTION: An overdischarge is judged (S108) in the case of a short periodic battery temperature rise up rate dT/dt at discharge time exceeding a prescribed threshold value (S104), so that the overdischarge can be surely detected regardless of reliability of overdischarge judgment (S102) by terminal voltage judgment. Since a circuit mechanism itself relating particularly to detection and judgment of a battery temperature is ordinarily previously assembled in a battery pack of an electromobile or the like, overdischarge judgment performance can be improved with almost no device scale increase.

Title: Semiconductor read-only memory
Inventor: IWAHASHI HIROSHI
IPC: G06F11/00
Filed: 1983-09-21
Abstract: PURPOSE:To save a defective memory cell even if data are stored during the manufacturing process, to shorten the saving time and to reduce the fail probability of the saving by outputting level data different from the stored contents when a defective storage element is detected. CONSTITUTION:If a defect is detected in a storage element by reading out data in a read-only memory (ROM) cell array 31, a column/row signal transmission control circuit 46 corresponding to the address of the element is controlled, and when the defective storage element is accessed, a detecting circuit 43 decides the defective storage element by the output of the corresponding circuit 46. A data output circuit 42 is controlled by the decided output A and a signal read out from the defective storage element is inverted, so that the read output becomes practically correct data. Even if data are stored in the manufacturing process, said constitution makes it possible to save the defective memory cell for a short time with the reduced saving fail probability.

Filed: 1983-09-20
Abstract: PURPOSE:To obtain an LSI for peripheral device which has abundant functions with high performance by setting an action mode in an initialization mode and executing and controlling abundant functions including an encoding function, etc. based on the set action mode. CONSTITUTION:The 1st action mode flag is set to a mode setting register 14 when the 1st action mode is set. The key data fed by a key is transferred to an encoding part 12 and converted into a corresponding JIS code. This JIS code is written to a buffer 13. In this case, a writing pointer is set at +1. When the difference obtained between the reading and writing pointers is positive, the written code data is transferred to a transfer register of a UART part 17 via an internal bus 20 and shifted out through a terminal TxD in a set Baud rate. The reading pointer is set at +1 after it is read out of the buffer 13. Thus the code data is delivered serially from the terminal TxD in the 1st action mode.

Title: Current absolute value circuit
Inventor: NISHIMURA KOICHI
IPC: G01R19/22
Filed: 1985-08-09
Abstract: PURPOSE:To prevent the generation of a dead band during a change of the input current, by holding the common terminal of a current mirror circuit that forms a current absolute value circuit and the base of a transistor respectively at a prescribed potential. CONSTITUTION:The input of a current mirror circuit CM and the emitter of a transistor Q1 are interconnected to form a current input terminal Tin, while the output of the CM and the collector of the Q1 are interconnected to form an output terminal Tout, and a current corresponding to the absolute value of the input current at the input terminal Tin is outputted at the terminal Tout. A reference voltage of the earth potential is impressed to the base of the Q1, while a required negative bias voltage to the common terminal of the circuit CM. When a positive input current is impressed to the terminal Tin, the circuit CM goes ON while the Q1 goes OFF, and causes no affect on the output at the terminal Tout. With a negative input current, only Q1 goes ON, and the output of the circuit CM causes no affect on the output current. Thus, the voltage change at the terminal Tin due to the polarity of the input current is small, resulting in a decrease of dead band during polarity change, and the generation of dead band can be prevented.

Title: Material and method for covering conductor joint
Inventor: OGAWA NORIAKI
IPC: H01R4/72
Filed: 1987-07-14
Abstract: PURPOSE:To make it possible to cover a conductor joint easily with simple jig and tool by covering with a thermo-shrinking sheet over which a thermoplastic resin layer or thermosetting resin layer is formed. CONSTITUTION:A cover material 1 is made by forming a thermoplastic resin layer 3 or thermosetting resin layer over a thermo-shrinking sheet 2. After covering a conductor joint with the cover material 1 with the thermo-shrinking sheet 2 outside and the thermoplastic resin layer 3 or the thermosetting resin layer inside, the cover material 1 is heated and bonded to cover the conductor joint. Since the cover material 1 has the thermo-shrinking sheet 2 placed outer side, the cover material covering the conductor joint shrinks while being heat- pressed and completely follows the shape of the surface of the conductor joint. This causes the cover material sufficiently follows the external shape of the joint to come into close contact with the shape, improve sealing performance, and perfectly protects the joint against water.
