Patent JP-S6169303-A (JP)
Title: Controller for field chopper
Inventor: MAKI MIYOSHI
IPC: B60L15/22
Filed: 1984-09-13
Abstract: PURPOSE:To safely and effectively drive an electric railcar even when a field chopper becomes defective by disconnecting a shunt winding from the chopper and connecting in parallel with a main resistor. CONSTITUTION:When a chopper 9 becomes defective or a freewheeling diode 8 is damaged, a switch 11A is disconnected and switches 11C, 11D are switches. Thus, a shunt winding 3f is connected in series with an armature circuit, and a main resistor 4 is connected in parallel. Since the power drive characteristic of this circuit becomes series motor characteristic, it can be normally power driven.

Title: Production of 2,4-difluoroacetophenone
Inventor: MITSUHIYAERU MAIYAA
IPC: C07C45/46
Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To obtain the subject compound without problem on toxicity and environmental protection by using raw material 1,3-difluorobenzene as a reaction solvent when 1,3-difluorobenzene is reacted with an acetylating agent in the presence of Friedel-Crafts catalyst.  
     SOLUTION: 1,3-Difluorobenzene is reacted with an acetylating agent (especially preferably acetic anhydride or acetyl chloride) in the presence of Friedel- Crafts catalyst to provide the objective 2,4-difluoroacetophenone. In the reaction, 1,3-difluorobenzene as a reaction solvent is excessively used. Aluminum chloride, a fluoroalkanesulfonic acid, etc., is preferable as the Friedel-Crafts catalyst. 1,3-Difluorobenzene is preferably used in an amount of 1.2 to 5.0 mol, especially 1.8 to 3.0 mol based on 1 mol acetylating agent. After finishing the reaction, it is preferable to recover 1,3-difluorobenzene and reuse the compound in order to carry out the above reaction. The method can simply be carried out in industrial scale without using a solvent which is inadequate in respect of toxicity and environmental protection and is economical therefore.

Title: Instant camera
Inventor: NISHITANI YASUHIRO
IPC: G03B7/26
Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To provide an instant camera to which a power unit using an improved battery is suitably applied. SOLUTION: The instant camera is loaded with a main battery whose self- discharge rate is nearly equal to that of a primary battery and which can be repeatedly charged/discharged when a remaining amount is prescribed capacitance or more and a charging circuit for boosting the output voltages of auxiliary batteries, so as to charge the main battery. The auxiliary batteries 30A and 30B are stored in a film pack 22. When the film pack 22 is loaded in the instant camera, the auxiliary batteries 30A and 30B and the charging circuit are electrically connected to charge the main battery by the auxiliary batteries 30A and 30B. Thus, whenever the film pack 22 is exchanged, the auxiliary batteries are exchanged as well, so that the handling time of a battery exchange can be saved and there is no fear that the battery is dead.

Title: Speech decoding device
Inventor: MIURA TAKESHI
IPC: G10L19/005
Filed: 1993-08-02
Abstract: PURPOSE:To improve the aural speech quality by reducing the intermission of data due to decoding when an error is detected. CONSTITUTION:The number of limits N of a counter 12 and the number N of sent codes stored in a data buffer 13 are determined; when an error detector 11 decides that there is no error, sent codes from a transmission side are decoded by an ADPCM decoder 15 supplied with the codes through a selection switch 14 and the decoded codes are sent out as output data from a selection switch 17. If an error is detected, on the other hand, the counter 12 counts up in order of 1, 2, 3...N and data in buffers 2, 3...N in a data buffer 13 are passed through the selection switch 14 and decoded by the ADPCM decoder 15. When the counter 12 exceeds N, the decoded data whose amplitude is suppressed by a suppressing device 16 are sent out as output data from the selection switch 17.

IPC: H01L27/144
Filed: 1984-09-12
Abstract: PURPOSE:To obtain a semiconductor device having excellent consistency between a pattern for a light-receiving section and photosensitivity characteristics by implanting impurity ions to a region except the light-receiving section and inhibiting the generation of photocurrents in the region. CONSTITUTION:Four-divided light-receiving sections 20, 20, 20, 20 and electrodes 30, 30, 30, 30 are formed onto a chip 10. A lower layer in the chip 10 consists of an N<+> layer, and an N<-> layer is laminated onto the N<+> layer. An impurity is implanted to sections among each light-receiving section 20 and the external regions of the light-receiving sections 20 through an insulating film 40 to shape ion implanting regions 50. The impurity and defects are increased through the implantation of the impurity, the life time tau of carriers is shortened, and a photocurrent region moved by a diffusion is made small, thus improving crosstalk characteristics. Accordingly, the sharp change of photosensitivity in the light-receiving sections and regions except the light-receiving sections can be realized, thus acquiring photosensitivity characteristics excellently coinciding with patterns for the light-receiving sections.

Title: Electro-conductive transfer recording sheet
Inventor: HAYASHI SEIICHI
IPC: B41M5/26
Filed: 1983-10-13
Abstract: PURPOSE:To prevent the generation of shavings, by containing a specific amount of a higher aliphatic compound selected from aliphatic hydrocarbon, higher fatty acid, a higher aliphatic alcohol and higher fatty acid ester in an electro-conductive resistance layer. CONSTITUTION:0.2-20wt% of a higher aliphatic compound selected from aliphatic hydrocarbon, higher fatty acid, higher aliphatic alcohol, higher fatty acid ester and higher fatty acid amide is contained in the electro-conductive resistance layer of an electro-conductive transfer recording sheet. This higher aliphatic compound is added to and mixed in other components constituting the current passing resistance layer 2, that is, carbon black or a metal powder for imparting conductivity and a binder resin for sticking and dispersing the same in an amount of 0.2-20wt%. Because this higher aliphatic compound is well balanced in oleophilic and hydrophilic polar groups, it has good dispersibility in the binder resin and can be dispersed therein in a molecular state. When thermal transfer recording is performed by an electro-conductive head, shavings of the resistance layer is reduced to a large extent and image speckles can be almost eliminated.
