Title: Novel metal-free phthalocyanine crystal polymorphism and production thereof
Inventor: TAKANO SHIGEMASA
IPC: C09B67/50

Abstract: PURPOSE:To obtain the titled crystal polymorphism having specific greenish tint and excellent resistance to heat and solvents, by stirring an alpha-type metal-free phthalocyanine or milling it with mechanical stress for a sufficient period of time to convert its crystal form into other one. CONSTITUTION:An alpha-type metal-free phthalocyanine is stirred or milled with mechanical stress at 50-180 deg.C, pref. 60-130 deg.C for a sufficient period of time to convert its crystal form into other one, whereby the desired metal-free phthalocyanine crystal polymorphism characterized by an X-ray diffraction pattern with intensive lines at Bragg angles (2theta+ or -0.2 deg.) of 7.5, 9.1, 16.8, 17.3, 20.3, 21.4 and 27.4 can be obtd. Examples of the alpha-type phthalocyanines to be used are those prepd. according to method described by Moser and Thomas.

Title: Ic socket
Inventor: MATSUOKA NORIYUKI
IPC: H01L23/32
Filed: 1994-05-18
Abstract: PURPOSE:To interlockingly position the contact part of a contact so as to make contact with an IC lead, or to properly bring the contact part in contact with IC lead by letting the contact part wait at a contact release position for inserting IC by moving a contact open/close cover upward or downward. CONSTITUTION:When a contact open/close cover 4 is pressed down, the push pressing part 4a push-presses a pressure receiving part 3g against elasticity of a bent spring part 3d so as to rotationally move the contact part 3e of a contact 3 and presses down a pressure receiving arm 6d. Therefore, the contact part 3e and a separate fin 6b come in a waiting position and in this state, an IC package main body 5a is inserted into a space between ribs 13 so as to regulate is side face and stored in an IC storage part 2. At the same time, the tip part of a lead 5b is received by a lead support face 10 and when press- down force of the cover 4 is released, the cover 4 is raised by recovered elasticity of the spring part 3d. This raising allows the fin 6b to regulate the contact part 3e at its side face so as to pressure contact with the tip part of the lead 5b on the face 10. The contact 3 can thus make contact with the lead 5b properly while preventing twist and deviation.

Title: Clock demodulating circuit
Inventor: OOSHIMA KEN
IPC: H03L7/08
Filed: 1980-09-18
Abstract: PURPOSE:To obtain a continuous clock synchronous with an intermittent clock in the data in a stable way, by supplying an apparent continuous clock signal into a phase locked loop PLL circuit to perform a consecutive comparison of phase. CONSTITUTION:A D type flip-flop D-FF2 is set with the differential output of a differentiating circuit 9 to decide the point of initiation for the comparable range of phase. Then the D-FF2 is reset when the clock information gets into the comparable range. If no clock information gets into the comparable range, the output of a voltage control oscillator 8 is reset with a delayed signal. Accordingly if the clock information is within the comparator range, this information functions as the input of a phase comparator 6. Otherwise the output of PLL circuit 5, i.e. the output of the oscillator 8 is supplied to the comparator 6. In such constitution, the asynchronous clock getting into the phase comparable range can be reduced. As a result, a continuous clock synchronous with the intermittent clock in the data can be stably demodulated.

Title: Discharge exciting-type gas laser device
Inventor: KITAHARA TADASHI
IPC: H01S3/038
Filed: 1992-05-21
Abstract: PURPOSE:To provide a discharge exciting-type gas laser device which pre-ionizes uniformly and sufficiently the gap between main discharge electrodes, and can suppress consumption of pre-ionization electrodes. CONSTITUTION:Corona discharge electrodes 6 are mounted in the neighborhood of pre-ionization electrodes 3, 4. By generating corona prior to discharging between the pre-ionization electrodes, the gap between the pre-ionization electrodes 3 and 4 is ionized previously. Owing to this characteristics, discharge between the pre-ionization electrodes 3 and 4 becomes multi-arc discharge which has uniform expansion, and uniform ultraviolet light generates, and pre- ionization becomes also uniform. In the case of multi-arc discharge, the impact on the electrode surface is little. Therefore, consumption of the electrodes is suppressed, and metallic powder is reduced, and at the same time, the gap between the pre-ionization electrodes is kept constant.

Title: Catalyst for denitrifying exhaust gas and exhaust gas treating device
Inventor: MIZOGUCHI TADAAKI
IPC: B01D53/94
Filed: 1991-05-31
Abstract: PURPOSE:To simultaneously and economically remove the SOx and NOx in exhaust gases with high efficiency by bringing the exhaust gases and metal sult compd. into contact with a carrier consisting of a gypsum-contg. material. CONSTITUTION:An SiO2 compd. and/or Al2O3 compd. as well as lime and gypsum are used as raw materials and water is added to this mixture. After the mixture is kneaded, the mixture is subjected to curing and drying treatments under heating to form a desulfurizing agent. CaSO4 is formed from the limestone contained in this desulfurizing agent and the used desulfurizing agent is used if the desulfurizing agent is brought into contact with the gases contg. the NOx together with the SOx. Further, active components, such as iron, vanadium and copper, are deposited thereon to form a denitrifying catalyst. The carrier increases the gypsum content gradually to increase the acidity when this catalyst is brought into contact with the gases contg. the SOx and NOx. The activity as the denitrifying catalyst is then enhanced and the gases are denitrified with high efficiency. The desulfurization and denitrification are simultaneously executed in this way and the treatment is systematized.
