Title: Testing device for semiconductor device
Inventor: AMAI TAKASHI
IPC: G01R1/06
Filed: 1985-03-30
Abstract: PURPOSE:To enable an accurate test having high reliability by reducing the 'gouging' in a pad section on a test under the state of a wafer. CONSTITUTION:A testing device is formed in structure in which an approximately hook-shaped probe 13 is penetrated into an inserting hole 12 for a fixing card 11 vertically movably toward a lower surface from the upper surface of the card 11 and its midway of the probe 13 is fastened by a fixing member 15 fitted to the upper surface of the fixing card 11. An angle of bend theta of a bending section 13a in the probe 13 can be decreased without considering the height of a resin layer shaped to the lower surface of the fixing card to which a wafer is arranged. Accordingly, when the wafer to which a semiconductor device is manufactured is disposed on the lower surface side of the fixing card 11, the fixing card 11 is moved downward and the tip of the probe 13 is brought into contact onto an Al pad section for the semiconductor device, quantity of which the tip of the probe 13 is shifted in the horizontal direction while brought into contact onto the Al pad section for the semiconductor device can be inhibited, thus reducing the 'gouging' in the Al pad section by the tip of the probe 13.

Title: Production of thin-film transistor
Inventor: UEDA TORU
IPC: G02F1/136
Filed: 1991-03-29
Abstract: PURPOSE:To form a polycrystalline silicon layer to a smaller film thickness and larger crystal grains, thereby lower the threshold voltage of a thin-film transistor, increase mobility and decrease leak currents. CONSTITUTION:An amorphous silicone layer 2 is not yet subjected to a thickness reduction treatment and is in a thick state when the amorphous silicone layer 2 changes to the polycrystalline silicon layer 2' by receiving a heat treatment. The crystal grain sizes of the polycrystalline silicon layer 2' formed by the above-mentioned heat treatment, therefore, increase. Since such polycrystalline silicon layer 2' is formed thin, the polycrystalline silicon layer 2' is thin in the final and the crystal grain sizes thereof are large. The threshold voltage is consequently low, the mobility is large and the leak currents are less.

IPC: G11B5/31
Filed: 1990-03-19
Abstract: PURPOSE:To stabilize the length of a throat height by providing flat parts on a magnetic pole layer on the side nearer a slider substrate of two magnetic pole layers constituting paired magnetic poles and an inorg. material layer maintaining the gap of the front end throat height of the other magnetic pole layer. CONSTITUTION:A resin layer 20 for decreasing a step is formed on the lower magnetic pole layer 10 and in succession, the nonmagnetic inorg. material layer 18 is formed by sputtering. The beginning end of the inclined part of the upper magnetic pole layer 12 is th intersected point P 2 of the flat region part 18a of the inorg. material layer 18 and the rising region part 18b continuous therewith. The inorg. material, such as alumina, is hardly machineable and, therefore, even if the process of ion milling exits after the formation of this layer 18, the P 2 stabilizes as an invariable position. The length of the throat height 12e is, therefore, stabilized.

Title: Shift lever lock device for automatic transmission
Inventor: KOBAYASHI SUSUMU
IPC: B60K20/04
Filed: 1991-03-30
Abstract: PURPOSE:To prevent a careless start by locking a shift position at a neutral position interlocking with a brake operatin without making a shift operation difficult. CONSTITUTION:A regulating recess 7a is formed in a guide hole 7 of a detent plate 6 and fits and holds a grooved pin 8 of a shift lever 1 at a neutral position 10. A lock cam 15 can change over two positions of an allowable position for smoothing the regulating recess 7a and a preventing position for closing the regulating recess 7a. When the lock cam 15 is located at the allowable position, the regulating recess 7a is smoothed, a shift operation from the neutral position 10 can be performed without operating a release button of the shift lever 1. When the lock cam is located at the preventing position, the regulating recess 7a is closed and the shift operation from the neutral position cannot be performed. Thus, the start of a vehicle is prevented.

Filed: 1981-05-06
Abstract: PURPOSE:To prevent an overvoltage from being applied to a power transistor for controlling a current at the starting time of a motor by connecting a voltage drop element before reaching the prescribed number of revolution of the motor at the starting time. CONSTITUTION:A switching controlling circuit 8 conducts transistors 9-11 connected in series with motor coils 13-15 ON in response to the output of a Hall element which detects the rotating position of a rotor. On the other hand, a transistor 12 is controlled by a number of revolution control signal. A current is flowed through the motor via a resistor 23 at the time of starting the motor. When the number of revolution of the motor becomes the prescribed value, a relay 25 is closed, thereby shortcircuiting the resistor 23. In this manner, overvoltage is prevented from being applied to a power transistor at the time of starting the motor.

Title: Arrangement of functional block
Inventor: IDE MASAKO
IPC: H01L21/82
Filed: 1990-03-19
Abstract: PURPOSE:To make effective arrangement work and improve arrangement quality by performing delay calculation for each wiring and correcting an arrangement position based upon the result of the delay calculation. CONSTITUTION:Pairs of functional blocks B1 and B1', B2 and B2', and B3 and B3' are the same functional blocks but are different in their configurations. After among several combinations of temporal layout examples in such manner, a temporal layout being a minimum in the average of wiring lengths is selected, the delay calculation is performed. For the delay calculation, the existence of a flip-flop at the center of gravity of the blocks is assumed (the center of gravity is indicated by a mark X in the figure), and the center of gravity is taken as one end, and further the sum of the lengths of lines being perpendicular to each other is calculated, and finally a delay value corresponding to the sum is calculated. In such a manner, with an optimum layout taking the delay value into consideration, quality in an LSI design is improved and further preparation of the functional block and temporal layout of the functional block are automatically achieved. Hereby, effectiveness of the work is realized.
