Abstract: PROBLEM TO BE SOLVED: To decrease the warping of a semiconductor element mounted by a TAB method and to improve the strength of the semiconductor element itsef at the same time by providing the protective film of a heat shrinkable resin on the main surface and providing a heat shrinking resin on the back surface. SOLUTION: First and second circut protective films 3 and 4 comprising glass-based material and polyimide resin are applied and formed under a wafer state. The formation of a back-surface layer 5 comprising the polyimide resin is conducted by applying the resin by a spinner on the back surface of the wafer and thereafter heating the resin at 20 deg.C for 30 minutes. Then, even if warping of the wafer is generated due to shrinking due to at the forming time of the second circuit protective film, the warping due to the shrinking of the second circut protective film 4 made of the polyimide resin is offset by the shrinking of the polyimide resin forming the back surface film 5. Therefore, as a result the warping of the wafer is decreased. By cutting out the wafer in a chip shape, the semiconductor device, wherein the warping is less when the shape is made thin and long, is obtained.

Title: Routing method
Inventor: CHIYAARUZU EDOWAADO PAAKINSU
IPC: H04L12/56
Filed: 1994-12-19
Abstract: PURPOSE: To transmit packets between the stations of the ad-hoc network of a mobile station by using a route specifying table stored in the respective stations of the network. CONSTITUTION: Corresponding to the three schedules of indicating a new route corresponding to a request, cyclically indicating a lately changed route and thus providing the complete dump of all the known routes though a frequency is low, route specifying information is multi-cast. Multi-address communication is immediately started again by the new route and as a result, the information is quickly spread. The route is cyclically published and the public announcement is mainly useful for informing all adjacent stations that all the stored ones are still correct relating to a multi-address communication moving host in almost all cases. In order to weaken vibration, the information relating to the frequency of route change is held.  Based on the data, it is decided to delay the public announcement of the route to be changed soon and thus, the vibration of the route specifying table is weakened.

Title: Sample temperature control method for thermal analysis device and its controller
Inventor: TOMURA KOICHI
IPC: G01N25/00
Filed: 1988-12-15
Abstract: PURPOSE:To prevent the generation of a transient disturbance at the time point of a start and an end of a rise/fall temperature by inputting an ideal temperature curve to a first-order lag element, setting its output as a target temperature curve, and smoothening a bent part of the ideal temperature curve by a simple operation processing. CONSTITUTION:An ideal temperature curve setting device 10 sets an ideal temperature curve at the time of allowing a sample to ascend and descend at a constant speed. Its output is inputted to a first-order lag element 20, and this element 20 smoothens a bent part of the ideal temperature curve. An output of this element 20 is inputted to a target temperature curve calculating element 30. Subsequently, the element 30 calculates a target temperature curve by a simple calculation, based on two correction temperature curves. That is, by a first correction temperature curve F(t), a switching point C is determined, and by using this point as an origin, a second correction temperature curve G(t) is drawn, and from a time constant tau1 of a temperature rise start and a time constant tau2 of a temperature rise end, an initial temperature difference T0 is derived by the switching point C. From this simple operation, the curve F(t) and the curve G(t) are connected in the same inclined direction at the point C, and the bent part is smoothened.

IPC: H02J3/38
Filed: 1994-12-19
Abstract: PURPOSE: To prevent the occurrence of the delay time until the reference signal of an inverter output is formed by inputting the output of each D flip-flop into a microcomputer, correcting the reference phase signal on an inverter output and synchronizing the inverter output with a commercial power supply. CONSTITUTION: The pulse of a wavelength sent out from 'Q output' of a first D flip-flop 6 is inputted into 'input 2' of a microcomputer 8. The pulse of a wavelength sent out from 'Q output' of a second D flip-flop 7 is inputted into 'input 3' of the microcomputer 8. Then, the microcomputer 8 counts the number of clock pulses corresponding to the respective wavelengths by a built-in counter. The reference phase signal of the inverter output is corrected so as to decrease each phase difference based on the number of the clock pulses and a commercial zero-crossing signal inputted into 'input 1' of the microcomputer 8, and the result is sent out from 'output!' of the microcomputer 8.

Title: Shape measuring device and method therefor
Inventor: SEKIMOTO KIYOHIDE
IPC: G01B11/00
Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To surely discriminate the reflected light of a target and perform a highly precise range finding by receiving and calculating the reflected light from the target of a pulse laser beam by opening a gate only for a prescribed time according to the target. SOLUTION: The shape measuring device applied to, for example, cokes or iron ore in a hold of ship scans a pulse laser beam 5 along the whole surface of a target, receives the reflected light, and three-dimensionally measures the shape of the target from the time difference. A time measuring counter 22 opens a gate only for a prescribed time set according to the position of the target and processes the received signal during it. Thus, a signal such as reflection from a window can be removed. When a plurality of signals are received, the reciprocating time of the slowest signal is outputted, whereby the influence of dust in front of the target can be avoided.  The transmitted signal and the received signal are detected by respective prescribed thresholds and maximum values and approximated by a parabola, whereby a highly precise range finding can be performed even when the received signal is attenuated.

Title: Atomic absorption analyser
Inventor: SASAKI KIKUO
IPC: G01N21/01
Filed: 1986-12-26
Abstract: PURPOSE:To allow the capacity o a single luminous flux analyser to approach to that o a two-luminous flux type analyser, by performing base line correction. CONSTITUTION:The output signal Vl of an absorbancy difference circuit SL is directly inputted to a subtractor circuit SUB and also inputted to the circuit SUB through a sample holding circuit SH2. Since a sampling switch is closed during a time when a burner BN is retracted from a light path (x) and the circuit SH2 outputs the input signal as it is, two inputs of the circuit SUB during this time are equal and the output of the circuit SUB has already become a zero level. That is, during a time when the sampling switches of circuits SH1, SH2 are closed, the correcting operation of a base line is performed and the base line is held to a zero level. Therefore, the base line varies during a time when the circuits SH1, SH2 are in a sample holding state but, when the sampling switches of the circuits SH1, SH2 are closed, the correcting operation of the base line is reopened and the base line is returned to the original zero level and a measuring result free from the variation of the base line is obtained.

Title: Frequency synthesizer
Inventor: NAKANE MASABUMI
IPC: H03L7/187
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To widen a band, while spuriousness due to a quantization error is suppressed to a low level by synthesizing a period signal from a phase-locked loop synthesizer with a period signal from a frequency up converter which receives the output signal of a direct digital synthesizer and up-converting it into a specified frequency. SOLUTION: A memory 6 receives a chirp data function from a chirp data function generating part 5 and outputs frequency rough setting data and frequency fine setting data to the PLL(phase-locked loop) synthesizer 2 and DDS 3(direct digital synthesizer). DDS3 and the frequency up-converter 4 output a signal which is up-converted into a desired frequency through frequency fine setting data. A mixer 7 synthesizes the period signals from the PLL synthesizer 2 and the frequency up converter, and a filter 8 removes an unwanted wave. Thus, a chirp signal which is arbitrarily set can be outputted.
