Title: Production of pitch
Inventor: SATO MAKI
IPC: C01B31/00
Filed: 1987-04-15
Abstract: PURPOSE:To prepare pitch having a high degree of carbonization and free from mesophase, by hydrorefining coal tar pitch in the presence of a hydrogenating catalyst under particular conditions and conducting thermal reforming of the hydrogenation product. CONSTITUTION:Coal tar pitch (preferably soft pitch having a softening point of 70 deg.C or below from the standpoint of handleability) is hydrorefined in the presence of a hydrogenating catalyst (e.g., an Ni-Mo/alumina-base catalyst) to attain a degree of hydrogenation of at least 5g-H/kg-pitch in terms of the hydrogen absorption and a degree of denitrification of 80wt.% or less. The thermal reforming of the hydrorefined coal tar pitch is conducted at 350-450 deg.C for 0.5-10hr in a closed system. Thus, there is prepd. pitch having a high degree of carbonization and free from mesophase. The pitch thus prepd. exhibits high performance when used as binder pitch and impregnated pitch and is expected to improve the yield and properties of the product when used as a raw material for production of a graphite electrode for steel-making and a carbon electrode for aluminum refining.

Title: Complementary insulated gate field effect transistor integrated circuit
Inventor: SHIZUKUISHI MAKOTO
IPC: H01L21/8238
Filed: 1985-04-30
Abstract: PURPOSE:To obtain a complementary insulated gate field effect transistor integrated circuit in which the elements are highly integrated by selecting the material or the film thickness of the gate insulation film, thereby setting the electrostatic capacity of the gate portion depending on the elements. CONSTITUTION:A diffusion region 24 constitutes the drain of a transistor Q1 and is connected to an electrode 26 by means of a contact hole 34. A transistor Q2 includes two diffusion regions 20 and 38 which are formed in a P-type well 36 formed on one main surface of a substrate 30, and on the main surface therebetween a gate electrode 14 composed of a polycrystalline silicon layer is formed. The gate lengths of the transistors Q1 and Q2 are both L and are effectively equal. The gate width Wp of the transistor Q1 and that Wn of the transistor Q2 are set effectively equal. For instance, if the gate insulation film thickness d1 of the transistor Q1 is 1,200 angstrom and that d2 of the transistor Q2 is 300 angstrom, the ratio betaR of the gain factor beta2 of the transistor Q2 to that beta1 of the transistor Q1 is set to 4. As apparent from this example, a desired betaR can be obtained by changing the gate insulation film thickness according to the elements, and thus degree of freedom is increased in the selection of the width and length of the gate electrode.

Filed: 1994-04-28
Abstract: PURPOSE:To prevent the generation of the sag of the paint on a inclined surface by determining the thickness of the paint film sticking to a surface to be coated and the inclination of the surface to be coated with a gravity direction and evaluating whether the sag arises from the painting sag threshold on the perpendicular surface. CONSTITUTION:The vertical plane sag threshold film thickness muMAX1 of the paint is set. The paint film thickness muSuf1 of the specific surface Suf1 is detected. Further, the film thickness of the threshold at which the paint begins to sag when the perpendicular surface inclines by an angle thetagp1 with the painting sag threshold on the perpendicular surface as a reference is determined from the inclination of the specific surface determined from the angle thetagp1 formed by a gravity vector (g) and the normal vector p<1> of the surface Suf1. Whether the paint sag arises or not is then evaluated. The evaluation is similarly made with the surface Suf2 as well and the sag of the paint is evaluated for one patch to be enclosed. The sag of the paint is evaluated for all the surfaces to be coated as well.

Title: Starting clutch controller for automatic transmission
Inventor: YAMAGUCHI HIROSHI
IPC: B60W10/04
Filed: 1985-04-30
Abstract: PURPOSE:To alter clutch clamping timing in response to the operating amount of an accelerator pedal as well as to solve a problem of all drawbacks due to instability in a slow pace of the clamping timing, by controlling the clamping pressure according to an integration value of an engine output equivalent signal. CONSTITUTION:A signal (s) showing the starting time of an automatic transmission is gradually heightened in controlling the clamping pressure of a clutch via a clamping control valve 3 by means of input from an input sensor 5 after a control signal (c) corresponding to an integration value of an engine output equivalent signal (e) is outputted to an actuator 4 from a controlling device 6. That is to say, at the time of transmitting the signal, in the case where the operating amount of an accelerator pedal is large (engine output is large), clamping of a transmitting clutch 1 is hastened. Likewise, in the case where the operating amount of the accelerator pedal is small (engine output is small), the clamping of the transmitting clutch 1 is delayed to some extent. In consequence, a clamping shock due to instability in a slow pace of clutch clamping timing is eliminable.
