Title: Mounting method of semiconductor device
Inventor: TOMINAGA KAZUYOSHI
IPC: H01L21/60
Filed: 1981-10-27
Abstract: PURPOSE:To attain compactness and thinness and to reduce the number of processes by a method wherein a resin mold member is applied on a circuit substrate before face bonding and the mold member is flowed into a gap between the substrate and a semiconductor chip to prevent blister formation. CONSTITUTION:A suitable amount of a resin mold member 23 is applied on a circuit substrate 21 facing to a semiconductor chip 22. The chip 22 exactly established a face down bonding position by a bonding machine is set through the member 23 and is pressed and heated by a heating tool, a pulse heater or the like 24. In this way, a soldering bump 26 is connected to a conductive pattern 25 and the chip 22. At that time, the bump 26 penetrates the member 23 to connect to the pattern 25, furthermore, solder is melted by heating and is connected to the pattern 25 by diffusion. Therefore, no member 23 exists between the bump 26 and the pattern 25 and the member 23 is flowed into a gap between the substrate 21 and the chip 22 to prevent blister formation.

IPC: H04L27/18
Filed: 1982-09-30
Abstract: PURPOSE:To generate an alarm at a transmission and receiving terminal station even if a transmitted input pulse signal is interrupted by providing forcibly a prescribed angle of phase rotation to a transmission side signal so as to keep the synchronizing state of a communication system. CONSTITUTION:Input signals IN1, IN2 are transmitted through OR gates 9, 10, transmission side differential logical section 1 and a phase modulator. On the other hand, the input signal is inputted also to an input detecting circuit 8, and when the input signal is interrupted for a long time, a ''1'' signal is generated at an output of an NOR gate 19 by utilizing the integrating characteristic of capcitors 13, 17. This signal ''1'' generates an alarm ALM' and is applied to the gates 9, 10 to bring the output to 1. The output 1 of the gates 9, 10 changes the modulated phase of the transmitted signal by each pi rad, and the receiving side utilizes this phase change to assure the synchronism, and to generate the alarm.

Inventor: NISHIHARA TOSHIKAZU
IPC: G11B5/85
Filed: 1998-06-04
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of splashes and to improve a working rate and productivity by constituting the contamination member existing in an upper part of contamination members of a travelable belt-like contamination member and parting the end of the contamination member existing in the lower part in a central direction of a cooling can roll from right above the melting part of a crucible. SOLUTION: Deposits are respectively deposited by ineffective vapor on the belt-like contamination member 24 and the contamination plate 13 simultaneously as vapor deposition starts. Since the belt-like contamination member 24 travels at a prescribed speed at all times, the deposits are melted and are transported in a direction parting from right above a magnetic material 8 and the stagnation of the deposits at one point and the growth thereof are prevented. The deposits grow even at the end 13a of the contamination plate 13 but even if these deposits fall, the end 13a exists in the position parting from right above the molten magnetic material 8 and, therefore, the deposits fall to the outside of the crucible 9 and the generation of the splashes of the melt is prevented.

Title: Electric shock preventive circuit
Inventor: HANEDA YOSHIHITO
IPC: H04N5/63
Filed: 1995-07-07
Abstract: PROBLEM TO BE SOLVED: To detect the stoppage of the supply of DC current and then rapidly discharge residual voltage from a load by turning a switching section from an OFF state to an ON state when a detecting section detects a specified voltage. SOLUTION: In the case that a cable is pulled out by mistake during the operation of an electronic equipment, a detecting section 5 detects that a power line A of a first load section 2 which is driven by low voltage comes to a specified voltage and then it turns a switching section 6 from an OFF state to an ON state. By this, a power line D of a second load section 3 which is driven by high voltage is grounded and thereby residual voltage of the second load section 3 is rapidly discharged. Therefore, a power line connected to a connection pin of a connector of a cable 4 becomes zero volt and it is not feared that when someone touches the connection pin, he or she touches the voltage before discharging.

IPC: G01N21/41
Filed: 1988-07-12
Abstract: PURPOSE:To easily and securely measure the concentration of liquid by providing a rod part, a light emission part, and a light reception part. CONSTITUTION:When the rod part 1 is inserted into a sample 5 and the light from a projection part is entered slantingly into the rod 1, the light is reflected by the border surface between the flank of the rod 1 and a tip part 2 and travels backward in the rod 1 to enter the light reception part 4. In this case, larger reflection is caused on the flank of the rod 1 and the liquid contact surface of the tip part 2 as the refractive index ratio of sample liquid and the material forming the rod 1 is smaller, so the light intensity at the light reception part 4 is larger and larger as the refractive index of the sample is smaller and smaller. Further, a tip mirror part 6 and an upper end mirror part 7 are provided to the tip part 2 and the upper end part of the rod 1. Further, a mirror part 6 is provided and then reflection is caused only at the measurement part 8 of the rod, so that large output variation based upon variation in the refractive index ratio to the sample can be extracted. Thus, the concentration of the liquid is easily and securely measured.
