Title: Holding chuck for ic component
Inventor: MARUO TOMOHIRO
IPC: H05K13/04
Filed: 1988-12-29
Abstract: PURPOSE:To accurately position even IC components having different lead pitches and the number of leads by using a magnetic attraction wall having the same width as that of the lead group of the IC component. CONSTITUTION:When a lower end face 4 approaches from above to an IC component 2 to be attracted and held, the IC component 2 is attracted to and held by the lower end face 4 by the magnetic attraction force to the leads 12 of a permanent magnet 5. Gas flow from a pressure gas source is injected from a gas jet port 9 in this state to attract and hold the IC component 2 in a noncontact state. The lead group 12 of the IC component 2 is so moved horizontally to the lower end face 11 of a magnetic plate 6 in a noncontact attracting and holding state that the number of lines of magnetic induction passing the leads 12 becomes maximum. In this case, since the lead group 12 and the lower end face 11 have the same width, the lead group 12 is so moved as to coincide at the lateral center with the lateral center of the lower end face 11. Thus, even IC components 2 having different lead pitches and number of leads can be accurately positioned.

Title: Reversible thermal recording material
Inventor: MARUYAMA KATSUJI
IPC: B41M5/36
Filed: 1989-12-22
Abstract: PURPOSE:To manufacture a reversible thermal recording material having a high contrast, excellent environment-resistant shelf stability and allowance in heating control by using one kind of a compound selected from a higher fatty acid having a hydroxyl group and a higher fatty acid having an oxo group as an organic low molecular substance dispersed into a resin base material. CONSTITUTION:A heat-sensitive body mainly comprising an organic low molecular substance dispersed into a resin base material is brought to a cloudy opaque state at normal temperature such as T0 or lower. When the heat-sensitive body is heated at a temperature between T1-T2, it is brought to a transparent state, and left as it is transparent even when the temperature between T1-T2 is returned to normal temperature of T0 or lower again. When it is heated at a temperature of T3 or higher, it is brought to a semitransparent state. When the temperature is lowered gradually, it is returned to the cloudy opaque state again, not the transparent state. Consequently, when heat is applied selectively, a cloudy picture can be formed on a transparent foundation and a transparent picture on a cloudy foundation, and the change can be repeated any time. A higher fatty acid (favorably 16C or more) having a hydroxyl group and/or a higher fatty acid (favorably 16C or more) having an oxo group is selected as the organic low molecular substance.

Title: Semiconductor device
Inventor: SHINOZAKI NAOHARU
IPC: G11C11/41
Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To obtain such constitution that a device performs normal operation even if an undefined input is inputted to a mode register setting an operation mode by selecting this when an input signal indicates one out of N operation modes, selecting the prescribed one when it is an undefined input signal other than the above, and operating in accordance with an operation mode selected by a selecting circuit.

A NOR circuit 20 receives output of the inverters 17-19, and outputs a HIGH (selection) signal only when output of inverters 17-19 are all LOW (non-selection). Output of a NOR circuit 20 is a code signal CL1 and output of the inverters 17-19 are code signals CL2-CL4 respectively. By using a decoder having such constitution, even if undefined setting is performed, malfunction of a device can be prevented by allotting the setting to one of defined output.
