Title: Method and equipment for manufacturing semiconductor device
Inventor: FUNATSU KATSUHIKO
IPC: H01L21/52
Filed: 1996-05-01
Abstract: PROBLEM TO BE SOLVED: To provide a technology which eliminates remaining voids by preventing gas from being taken in between conductive solder material and a semiconductor chip. SOLUTION: After applying conductive solder material 11 on a conductive board 11, a semiconductor chip 9 is tilted under the condition that the conductive solder material 11 is heated to the melting point or above, and one edge 9a of the conductive solder material 11 is placed on the conductive solder material 11. Then, the semiconductor chip 9 is placed on the conductive solder material 11 so as to be parallel as a whole to the conductive board 10, by gradually bringing down the other edge 9b. Thus, since the semiconductor chip 9 is placed on the conductive solder material 11 by gradually tilting from the edge 9a, gas is prevented from being taken in.

Title: Fuel injector
Inventor: KANOU KOUJI
IPC: F02M69/32
Filed: 1984-06-01
Abstract: PURPOSE:To prevent storage of fuel in the detouring path of a fuel injection valve arranged in the upstream of a throttle valve, by providing a detouring path communicating between the upstream and the downstream of the throttle valve while arranging a gate valve at the inlet of the detouring path. CONSTITUTION:A solenoid valve 7 is arranged at the inlet 5 of an air bypath of detouring path 8 opening above an injector 4. A screw 6 for regulating the maximum bypass airflow is arranged at the bypath air outlet 9 opening to the downstream of the detouring path 8. An orifice 10 is opened in the vicinity of the inlet 5 to flow the intake air continuously into the detouring path 8. Consequently, fuel is never stored in the detouring path 8 to achieve specific increase of air flow even upon provision of valve-open instruction to the solenoid valve 7 to open the valve body 71, resulting in optimization of the air/fuel ratio.

Title: Molding method for frp
Inventor: KUROKAWA IKUJI
IPC: B29C39/24
Filed: 1979-08-30
Abstract: PURPOSE: To raise the workability, moldability and productivity of FRP by a method wherein reinforcing fibers are blown into a cavity from an injection port for both pairing dies to fill up the cavity and then the liquefied synthetic resin for matrix is injected.  
     CONSTITUTION: By using both upper and lower pairing dies 11 and 12 to which the release treatment is applied, first, in the state of temporary die-pairing, reinforcing fibers 15 are blown from an injection port 14 into a cavity 13 by a filling device 16, thereby the cavity being filled up. Next, after the dies being paired closely, the synthetic resin for matrix such as, for instance, polyester resin combined with a curing agent and an accelerating agent is pressed into the cavity 13 filled up with the reinforcing fibers 15 through a nozzle part 21 arranged at the injection port 14 for both pairing dies 11 and 12. Then, the injection port is blocked up, and the resin is released from the dies after being set through chemical reaction, thus an FRP product being obtained. The reinforcing fibers to be employed are desirably 3W25mm in length. If they are 3mm or less in length, their reinforcing effect is small, while it turns to be difficult to fill every corners of the cavity when the length is 25mm or more.

Inventor: OGINO NAOYUKI
IPC: G09F9/00
Filed: 1989-04-30
Abstract: PURPOSE:To thin the constitution of the back-lighted switch device and also heighten the degree of freedom in selecting indication colors by forming a switch device using a liquid crystal plate which has a dousing function, and also providing a light source independently of the device. CONSTITUTION:Light emitted by a shared light source 4 provided independently of the device main body 7 is transmitted through a light transmission type liquid crystal cell 10 and a display panel 9 made of light transmitting material so as to display characters and figures on a display panel 9, the cell 10 exhibiting a light shuttering function by application of a voltage which is carried out according to control of the transparent sheet switch 11 of the main body 7. By the constitution in which the light source is provided independently of the switch main body, the constitution of the back-lighted switch device main body is thinned, and the use of liquid crystal makes unnecessary the use of a darkred-colored thin plate for preventing the inside from being seen and so the degree of freedom in choosing indication colors is heightened.

Title: Jamming eliminating device
Inventor: KONISHI YOSHIO
IPC: H04B1/10
Filed: 1987-05-08
Abstract: PURPOSE:To eliminate a disturbing radio wave with the same frequency as that of a desired wave but in different direction by converting a disturbing wave input to one of two antennas installed at a prescribed interval into a signal of the same level but with a phase difference of 180 deg. and mixing the result. CONSTITUTION:The antennas 8, 9 are installed at a prescribed interval. When the frequency of the desired wave and that of the disturbing wave are the same and the incoming direction differs, the output of the antenna 9 is given to an attenuator 11, an amplifier 12 and a phase shifter 13 so as to adjust the output of the disturbing wave to be of the same level as the output of the disturbing wave from the antenna 8 with a phase different by 180 deg.. Then the output is mixed with the output of the antenna 8 at a mixer 14 to cancel the disturbing wave. On the other hand, since the phase angle of the desired wave differs from that of the disturbing wave, it is not cancelled. Thus, the disturbing wave is eliminated without deteriorating the quality of the desired wave.
