Title: Stereo sound coding device
Inventor: SATO KAZUMI
IPC: H04B14/06
Filed: 1989-06-16
Abstract: PURPOSE:To reduce the deterioration in the reproduced sound quality of a sub channel caused at the changeover of main and sub channels by providing independently an adaptive control section when a right channel is a main channel and an adaptive control section when a left channel is a main channel. CONSTITUTION:Right main channel adaptive control sections 5, 15 and left main channel adaptive control sections 6, 16 are provided respectively to sender and receiver sides. For example, when some of plural talkers use right side microphone 1 and others of the talkers use left side microphone 2 alternately, the right main channel adaptive control sections 5, 15 reproduce adaptively the sound in the indoor acoustic state at that time in the case of using the right side microphone and the left main channel adaptive control sections 6, 16 reproduce adaptively the sound in the indoor acoustic state at that time in the case of using the left side microphone. when the left and right channels arc replaced, the device is at a halt to keep the preceding state and when the right and left channels are replaced, the device is in immediate adaptive operation as the continuity of the preceding state. Thus, the sound quality deterioration in the sub channel at the channel changeover is reduced.

Title: Exhaust emission control device for internal combustion engine
Inventor: ISHIZUKA YASUJI
IPC: F01N13/02
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To improve NOx treatment capacity at the time when an air-fuel ratio is switched from lean to stoichiometric or rich, by setting a total amount of components supported by a catalyst located at an upstream side of a three way catalyst, to be less than that supported by the three way catalyst, and contributing to the oxygen storage capacity, by almost specific times. SOLUTION: A NOx absorption catalyst 7 and the three way catalysts 6, 8 support ceria Ce as a component which contributes to the oxygen storage capacity. A ratio of the total amount A+B of ceria of the three way catalyst 6 and the NOx absorption catalyst 7, to an amount of ceria C of the three way catalyst 8, satisfies that [(A+B)/C] is almost 1.2 or less.  The oxygen storage capacity of the three way catalyst 6 and the NOx absorption catalyst 7 is lowered by the reduction of the amount of ceria (A+B), in comparison with a case when the amounts of ceria of the NOx absorption catalyst 8 and the three way catalysts 6, 8 are almost same each other, whereby an amount of desorbed oxygen is lowered even when the combustion is switched from lean to storichiometric (or rich), so that the NOx can be effectively reduced, and the atmosphere in the NOx absorption catalyst 7 and the three way catalyst 8 is comparatively quickly enriched to be a reducing atmosphere.

Title: Word processor

Filed: 1988-06-23
Abstract: PURPOSE:To perform the reconversion between KANJI (Chinese character) and KANA (Japanese syllabary) without holding the input reading KANA string by performing the KANJI/KANA conversion for a Japanese word sentence already converted into a KANJI-KANA sentence and restoring said reading KANA string. CONSTITUTION:A KANA/KANJI conversion part 2 converts the input reading KANA strings into a KANJI-KANA sentence and stores the result of this conversion into a sentence memory part 3. A partial character string is designated for the KANJI-KANA sentence stored in the part 3 and the reconversion is instructed. Thus a KANJI/KANA conversion part 4 converts the partial character string of the designated KANJI-KANA sentence into a reading KANA string and sends the result of this conversion to the part 2. The part 2 converts the reading KANA string into a KANJI-KANA sentence different from the previous one and replaces the result of this conversion with the contents stored previously in the part 3. Thus the reconversion is possible at an optional point even though no reading KANA string is held.

IPC: G11B7/24
Filed: 1981-09-30
Abstract: PURPOSE:To obtain the heat mode light recording medium which can be erased and rewritten by including a light absorbing dye or a pigment, and forming a light recording layer. CONSTITUTION:An acrylic resin is a solid which includes atomic group shown by the specified formula (where R1 is a hydrogen atom or an alkyl group and R2 is a substituted or non-substituted alkyl group) and has number averaged molecular weight of about 100,000 or less. The recording layer which includes said  acrylic resin and the light absorbing dye or the pigment, is formed on a substrate. The layer, which is generated from a semiconductor such as He and Ne and has the wavelength of about 400-850nm, is converged on said recording layer in order to soften the acrylic resin, and a minute recording bit is formed. In this case, the recording bit does not reach the bottom of the recording layer under the ordinary irradiating conditions, and the acrylic resin and the light absorbing dye or the pigment remain at the botton of the bit. Therefore, sensitivity is excellent and the broadening of recording energy is very small.

Abstract: PURPOSE:To make it possible to give the heating control under most suitable conditions for the weight of a food by transmitting the load received on a rail through the side wall of a heating chamber to its outside and holding and detecting the transmitted weight by a Roberval mechanism. CONSTITUTION:The load of a food 1 and a loading table 3 which bears on the right and left rails 4a and 4b penetrates the side walls and it is transmitted to a parallel motion metallic member 6 in the up-and-down direction through a connecting body 5. The load is pulled upwards by a suspension metallic member 10, and the left and right loads are changed in their direction and combined by means of a direction coversion metallic member 11. Those loads then concentrate on a load-combining metallic member 12. The combined loads are received by a metallic lever member 19, and the loads thus received is received by a pressure sensor 21 on the opposite side of the lever 19 using a fulcrum metallic member 20 as a fulcrum. The pressure sensor 21 receiving load changes in its electrostatic capacity and this change is converted to frequency by an oscillation circuit and frequency is counted by a microcomputer to obtain weight. The microcomputer 27 controls the outputs of the magnetron 17 and the heater 18 on the basis of most suitable heating output, heating time and heating mode.
