Title: Original reader and image forming device
Inventor: TAKEUCHI IKUO
IPC: H04N1/04
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To prevent decrease in the productivity of an original reader and an image forming device by properly correcting a drive condition of a scanning optical system even when the drive condition of the scaning optical system is changed due to a temperature change. SOLUTION: When copying is finished (2010), a counter starts counting and a RAM stores a temperature t1 of a motor at the time (2020). The count is set to a prescribed time T minutes (2030). A temperature t2 is again detected after the T minutes in a step 2040, and when a temperature change t1-t2 exceeds a preset temperarue Δt in a step 2050, preliminary scanning is conducted. The decision by the step 2050 is repeated every T min while updating the temperature t1 stored in the RAM (2070, 2080).

Title: Preparation of high-molecular weight phenolic resin
Inventor: SAKAMOTO TAKAAKI
IPC: C08G8/00
Filed: 1978-02-28
Abstract: PURPOSE: To obtain the title phenolic resin with a low free phenol content, by addition condensation of a phenol and an aldehyde in the presence of a Lewis acid and an acid catalyst.  
     CONSTITUTION: A phenol and an aldehyde are subjected to addition condensation in the presence of an acid catalyst, and a Lewis acid is added to the reaction mixture from the time the reaction is completed till the removal of the condensed water. If most of the aldehyde is reacted before the addition of the Lewis acid, a considerably high molecular weight phenolic resin is favorably prepared. The molar ratio of the phenol to the aldehyde in the first stage is as high as possible, and the maximum one, about 0.9:1 is advantageous free from fear of gelation even after the sufficient reaction of the aldehyde. The amount of the Lewis acid is 0.01W5 % based on the phenol charged.

Title: Method and device for inspecting leakage
Inventor: AARTS MATHIAS LEONARDUS C
IPC: G01M3/32
Filed: 1985-02-08
Abstract: A method and an apparatus for detecting a possible leak in a vacuum package 104, in which the vacuum package is received within a wrapping wall 102 at least essentially consisting of a gas- tight, flexible wrapping foil adapted for substantial adjustment to the contours of the vacuum package under the influence of overpressure, so that the vacuum package is tightly enveloped by the wrapping wall. Overpressure is applied to the wrapping foil such that this adjustment to the contours of the vacuum package is effected without sealing any leak present, ensuring that the pressure exteriorly of the vacuum package remains higher than the pressure within said vacuum package. Hermetic sealing from the outside air is effected in the residual space 118 remaining between the vacuum package and the wrapping wall during a predetermined detection period, the pressure being gauged in function of the time.

Title: Automatic key word extracting device
Inventor: KIMOTO HARUO
IPC: G06F17/30
Filed: 1987-02-05
Abstract: PURPOSE:To improve the retrieving efficiency with use of a key word by analyzing the syntax and context in a Japanese sentences via a parallel word processing part and a context processing part and deleting the parallel words and the rendered words together with the derivatives to be used as verbs and adjective verbs deleted out of the key word candidates via a suffix processing part. CONSTITUTION:A parallel word processing part 14 deletes the parallel words shown by 'YA' (verb), a punctuation mark ',' and a centered period '.', i.e., those words having low degrees of emphasis compared with a case where these words are expressed alone out of the Japanese sentences to undergo extraction of key words as the undesired key words. A context processing part 15 deletes the words expressing the same subject in different ways of expression, i.e., the rendered words out of said Japanese sentences as the undesired key words. Furthermore a prefix processing part 16 deletes such words that are derived from the adjective verbs like 'KINDAIKA (modernization)' and 'KINDAITEKI (modern)', the combination of nouns and suffixes, for example, out of the key words extracted as nouns as the undesired key words. Thus the retrieving efficiency is ensured with use of key words.

Title: Delay circuit
Inventor: FUIRITSUPU KENTO HAADEIJI
IPC: H03K5/13
Filed: 1983-02-15
Abstract: PURPOSE:To give a long delay for an input pulse having a short time width, by generating a ramp transition voltage with an even number of gate elements connected in series and delaying the input pulse. CONSTITUTION:A leading front edge L of the input pulse is inverted in the gate element 2 and a trailing ramp voltage RL is generated with a capacitor 5. When the voltage RL reaches a threshold voltage VRET of the element 3, a voltage of a capacitor 6 is changed rapidly with the inverting operation of the element 3 and a delayed front edge voltage DL is generated. Further, when a trailing tail edge T of the input pulse appears, a rapid positive transition voltage T is generated at the output of the element 2, and since this voltage is inverted at the element 3, the voltage RT is generated across the capacitor 6. When this voltage crosses with the threshold voltage of the gate element 4, a delayed transition voltage DDT is generated. When further delay is desired, gate elements 10, 11 are added.

Title: Platinum alloy for accessory
Inventor: TAMEMASA HIROSHI
IPC: C22C5/04
Filed: 1983-02-16
Abstract: PURPOSE:To obtain a Pt alloy for accessories with superior mechanical strength and castability as well as superior workability by adding specified amounts of Sn and Cu to Pt as a principal component. CONSTITUTION:The composition of a Pt alloy used as a material for a ring, a necklace, a brooch, a tiepin, cuff links, etc. is composed of 84-96wt% Pt, 1-10wt% Sn and the balance Cu. The reason for the addition of Sn is that Sn improves the mechanical strength and castability while satisfying the requirements that the reaction with a casting mold must be inhibited during casting and that the concn. of oxygen can be controlled during casting. When the Sn content exceeds 10wt%, the workability is remarkably deteriorated. The reason for the addition of Cu is that Cu further improves the mechanical strength by hardening.
