Title: Long lead frame for semiconductor device
Inventor: OMAE SEIZO
IPC: H01L23/50
Filed: 1987-10-28
Abstract: PURPOSE:To prevent any cracking in mold resins from occurring by a method wherein slits extending in the direction making a right angle with the parallel direction of semiconductor devices are provided in section bars. CONSTITUTION:The slits 11 extending in the direction making a right angle with the parallel direction of semiconductor devices 3 are provided in the section bars 4 of a long lead frame 1. Consequently, either during the bonding process of the outer lead 2 or during the carriage of the frame 1 before or after the bending process, the displacement level of the section bars 4 due to the displacement of the mold resins 5 of the respective adjacent semiconductor devices 3 can be absorbed by the slits 11 to restrain the section bars 4 from colliding with resin bars 7. Through these procedures, any cracking in the mold resins can be prevented from occurring without fail.

Title: Production of glass fiber-reinforced resin
Inventor: TANIGUCHI HIROSHI
IPC: C08J5/04
Filed: 1984-12-28
Abstract: PURPOSE:To obtain FRP containing a large amount of glass fibers having long fiber length, by dissolving a resin in a solvent, mixing glass fibers to the solution, and removing the solvent from the mixture. CONSTITUTION:A resin (thermoplastic resin or thermosetting resin) is dissolved in a solvent (e.g. methylene chloride, carbon tetrachloride, etc.), and glass fibers are added and mixed to the solution. The solvent is removed form the mixture by heating. Glass fibers having relatively long fiber length can be mixed to the resin without breaking the fiber. The mixing can be carried out in a short time preventing the thermal degradation of the resin because the long-term thermal kneading is not necessary in the present process in contrast with the conventional method.

Abstract: PURPOSE:To eliminate a decrease in elastic modulus at the time of moisture absorption by providing a moisture-proof coating layer on the external surface of a magnetic field producing body which contains resin and has respective magnetic poles magnetized by orientation. CONSTITUTION:The main body part of a magnet roll 5 is formed by molding the whole including shaft parts of both ends integrally while magnetic powder is dispersed in resin such as nylon and then forming the respective magnetic poles by oriented magnetization. This nylon, etc., forming the main part of the magnet roll 5 has high moisture absorptivity in this state and the magnet roll 5 decreases in elastic modulus at the time of moisture absorption to increase in quantity of flexture, thereby increasing variation of surface magnetic flux on a nonmagnetic sleeve. For the purpose, the moisture-proof coating layer 11 is formed of a moisture-proof raw material over the entire external surface of the magnet roll body 5. Consequently, even when the magnetic field producing body 5 which contains the resin is used, a developing device which is small in the flexture of the magnetic field producing body at high humidity and causes no trouble as to images is obtained.

Title: Clock extracting circuit
Inventor: TOMA TAKASHI
IPC: G11B20/10
Filed: 1988-11-02
Abstract: PURPOSE:To obtain the optimum phase of a clock and data which is never fluctuated according to a temperature by comparing the phase difference between a demodulated signal and a signal latched by the clock. CONSTITUTION:A digital signal 1 is applied through a buffer 4 to a resonator 5, and the clock is extracted, shaped in a comparator 6, and inputted to a PLL 7. Variable capacity is used for the resonator 5,and an output phase is changed by the output of an amplifier 13. A PLL output phase is inverted by an inverter and given to a latch 8 together with the digital input signal 1. The rise of the signal 1 and the fall of the latch are detected in edge detection circuits 9 and 10, the phase difference signal between two inputs is obtained by an RSFF 11, and the resonator 5 is voltage-controlled through an LPF 12 and the amplifier 13. When the phase difference is 180 deg., the FF 11 generates an error signal V/2 and executes adjustment so that the clock and the resonance frequency of the resonator 5 can coincide with each other at this time. As the result, even when the clock frequency of the input fluctuates, the phase difference between the input of the latch 8 and the clock can be kept in 90 deg. all the time, and the resonance frequency can be kept.

Abstract: PURPOSE:To simplify the constitution of a burner and to improve combustion performance, by a method wherein the arrangement angle of the claw of a kettle holder and arrangement of the burner flame ports of a burner are set in a manner that the arrangement angle of the claw of the kettle holder and arrangement of the burner ports of the burner are displaced from each other so that, when a single claw coincides with a burner flame port, other claws do not coincide with other burner flame ports. CONSTITUTION:A single claw 4 of a kettle holder 3 formed with a plurality of claws is coincided with a burner port 2, contact with flame from the burner port 2 is practicable, but the other burner port of the burner 1 does not coincide with the claw 4 of the kettle holder 3. The claws 4 of the kettle holder 3 are six located at intervals of 60 deg., and when the burner ports are formed at equal distances of 360 deg./12, the burner ports are coincided with all of a plurality of claws 4 or displaced from all of them, and combustion performance is not decided. However, by forming the burner ports at intervals of 360 deg./11, the single burner port 2 coincides with the claw 4, but other burner ports 2 do not coincide with the claws 4 of the kettle holder. As a result, combustion performance is improved, and since no special processing on the burner is necessary, productivity is also improved.

Abstract: PROBLEM TO BE SOLVED: To provide a liquid-surface detector, which can discriminate whether a container is fallen down or emply without providing a means for detecting whether the container is in the normal attitude or not and can achieve a low cost and space saving. SOLUTION: When the apparatus comes into a fallen-down state, an overlapped float 7 forcibly moves a movable float 5 in the directions to a first lead switch 11 and a second lead switch 13 regardless of the state that liquid is contained in a liquid container 1 or not. As a result, the movable float 5 reaches the set position of the switch 11 and the overlapped float 7 reaches the set position of the switch 13, respectively. The switches 11 and 13 both perform the closing operation. Therefore, the signals indicating the detections of the floats 5 and 7 are outputted from the switches 11 and 13.
