Title: Ignition timing control device for internal combustion engine
Inventor: NOMURA TOKUYUKI
IPC: F02P5/15
Filed: 1994-04-11
Abstract: PURPOSE:To improve the startability of an internal combustion engine while ensuring the ignition performance at low voltage. CONSTITUTION:An ignition timing control device has a CPU 38, a backup IC 42, and an AND gate 53. The CPU 38 consisting of an arithmetic processing circuit calculates the ignition timing according to the operating state of an engine, and outputs a soft ignition signal IGTs. The CPU 38 outputs a pseudo starter signal STAout (signal level 'H') showing that the engine is in the substantially starting state when the starter signal STA is ON (signal level 'H') and the operating state belongs to a predetermined area. The AND gate 53 inputs the starter signal STA and the pseudo starter signal STAout, and outputs its logical sum signal as the starter signal STA to the backup IC 42. The backup IC 42 outputs a hard ignition signal IGTh when the signal level of the starter signal STA is 'H' and a soft ignition signal IGTs when it is 'L' to the ignition device through an output interface circuit 46.

Title: Amplifier circuit
Inventor: KOBAYASHI KAZUHIKO
IPC: H03F1/26
Filed: 1990-03-20
Abstract: PURPOSE:To simply decrease noise at a high level with a small sized circuit by providing an oscillator whose oscillating frequency is a frequency of out-band of the operating frequency of a high gain amplifier, whose output level is higher than a peak of noise in the absence of a signal input of the operating frequency band and which generates the signal and inserts it to the input signal to the input stage of the amplifier and providing a filter eliminating the signal at the outside of the operating frequency band to the output stage of the amplifier. CONSTITUTION:An oscillator 2 generates a signal So whose oscillating frequency is at the outside of the operating frequency of a high gain amplifier 1 and whose output level is higher than a peak level of thermal noise in the absence of the signal input of the operating frequency band. Then the output signal So is inserted at the input terminal of the amplifier 1 in the absence of the input signal at the operating frequency band to the high gain amplifier 1, amplified together with the thermal noise in existence in the input, and since the input S/N of the amplifier 1 is high, the noise level in the output of the amplifier 1 is lower than the amplifier output level of the signal So and the noise does not give any adverse effect on the other part of the circuitry. Then the amplified output of the signal So at the outside of the operating frequency and is eliminated by a filter 3.

Title: Blanks and manufacture thereof
Inventor: KAWASAKI HIROSHI
IPC: B65B61/00
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To prevent a making-off crack during the folding operation by preventing an impregnating agent from being contained in a making-off part provided in a folded portion or in the vicinity thereof in a blank formed of an impregnated raw paper to provide the rigidity. SOLUTION: In order to prevent a marking-off crack in which a folded portion is cracked in a stage in which a blank formed of an impregnated paper of high rigidity is formed as a paper container, an impregnant to increase the rigidity is prevented from being contained in a marking-off portion or in the vicinity of the marking-off portion. A gravure coater, etc., is used for impregnating the chemical to increase the rigidity in a blank base material, and since a portion to impregnate the impregnant to increase the rigidity can be patternized by a gravure block, the impregnant can be easily prevented from being contained only in the marking-off portion and in the vicinity thereof. A whole area may be impregnated after a masking agent is applied to the marking-off portion or in the vicinity thereof of the blank base material in advance.
Patent JP-H01244236-A (JP)
Title: Air conditioner
Inventor: NAGANO MASATOSHI
IPC: F24F13/08
Filed: 1988-03-25
Abstract: PURPOSE:To prevent the occurrence of a drift current in an axial direction and to prevent the occurrence of surging phenomenon, by a method wherein ribs each having a uniform height, width, and mounting pitch are formed throughout the whole area on the discharge side of a casing front plate, and apart of the rib has a mounting pitch lower than that of the rest. CONSTITUTION:In the case rib 4 is lacking, when draft resistance on the suction side of a cross flow fan 1 is increased due to choking of a filter, a drift current W (shown by an arrow mark) is about to be generated from the central part of the cross flow fan 1 toward two end parts having low air resistance, and in turn surging phenomenon occurs. Meanwhile, in a section (two end parts) having low air resistance, ribs 4' having a rib higher than that of ribs in a region X are formed in a position region Y being a downstream and a mounting pitch distance is decreased. Thereby, the draft area of an air discharge passage 9 is decreased and throttled. The generation of the drift current W flowing from a place having high intake air resistance to a place having low intake air resistance can be prevented, resulting in the possibility to prevent the occurrence of surging phenomenon.

SOLUTION: A magnetic material which can be recorded magnetically only in a demagnetized state at normal temperature is used to form a 1st recording layer 10 having a 1st recording area 11 and a 2nd recording area 12 on the magnetic recording medium. Then when the magnetic recording medium is manufactured, the 1st recording layer 10 is initialized into the demagnetized state. Further, an analog signal is recorded as data in the 1st recording area 11 and then read out, and a digital signal generated on the basis of it is recorded as data in the 2nd recording area 12.

Moreover, the questioning frequency coefft. changing section 206 decreases the questioning frequency coefft. of other questions at every questioning, changes the questioning frequency coefft. in accordance with the past questioning order, the lapse time from the previous questioning and the response time at the time of the learner's answer and again inputs the questioning frequency coefft. to the min. questioning frequency coefft. retrieving section 201. The questioning is executed in the order taking the past questioning condition and the results of the learner's answers into consideration in such a manner and, therefore, the learning effect is enhanced.

Title: Fluorescent lamp
Inventor: URATA YOSHIZOU
IPC: H01J61/46
Filed: 1980-05-29
Abstract: PURPOSE:To improve both the luminous flux maintenance and the strength of a fluorescent lamp by using alumina and a metal borate in preparing a phosphor film. CONSTITUTION:The inner wall of a bulb having an outer diameter of 25-32mm. is coated with a phosphor film, which contains 0.1-1.5wt% of a metal borate, and alumina having a grain diameter of below 100mmu. The ratio of the former metal borate to the former alumina is below 0.2. As a result, the addition of a small  amount of the metal borate to the phosphor film formed on the inner wall of the  bulb of a lamp having a small outer diameter improves the luminous flux maintenance of the lamp. If the proportion of the metal borate to the phosphor exceeds  1.5%, the luminous flux maintenance will be decreased since the phosphor is hardly  sintered and binder which is not decomposed remains. In addition, the strength of  the lamp can be improved by restricting the ratio of the metal borate to alumina to  below 2.0, since the strain in the glass which is developed in the interface between  the glass and the metal borate is relieved.
