Title: Heat accumulating device
Inventor: KOUSOGABE HIROKATSU
IPC: F24H4/04
Filed: 1981-04-27
Abstract: PURPOSE:To improve the heat exchange efficiency of the titled device and the efficiency of a heat accumulating tank by a method wherein a partition wall is provided to  divide the space within the heat accumulating tank into a heat accumulating water  zone and a heat exchange water zone for receiving a heat adsorbing the heat radiating heat exchanger and circulation passages are formed at the upper and the lower ends  of the partition wall. CONSTITUTION:Water heated by a water-coolant heat exchanger rises upward within  the heat exchange water zone 2d as the density of the water becomes low and then  enters the heat accummlating water zone 2c through an upper clearance 2e. At the  same time, the water which is within the heat accumulating water zone 2c and which  is not yet subjected to a heat exchange action is supplied into the heat exchange  water zone 2d. In this case, the heat accumulating water zone 2c is divided into two  layers of which one is the layer in which hot water produced by a heat exchange action is pooled and the other is the layer in which is not heat exchanged is pooled. The boundary of the two layers comes to move downward gradually as time lapses while  keeping the densities of the two layers stabilized. Thus, when the boundary moves  down to the lower clearance 2e, the heat accumulating water zone 2c is filled with the  hot water produced after the heat exchange action so that no dead water zone is left  in the vessel 1.

Filed: 1988-03-16
Abstract: PURPOSE:To improve the reliability of data writing and to increase the speed of data writing by reading out written data via a reading head in parallel with a data writing action carried out via a writing head. CONSTITUTION:The data written successively in a floppy disk 13 by a writing head 10 are instantaneously given to a cyclic redundancy checker CRC31 via a reading head 12 set contiguous to the head 10. Thus it is not required to wait for the temporary end of a series of data writing actions and therefore the writing abnormality is roughly checked within the data writing time. As a result, the data writing reliability is improved and at the same time the data writing speed is increased.

Title: Production of 2,3,5-trimethylbenzoquinone
Inventor: SHIMIZU MASAO
IPC: C07B61/00
Filed: 1988-03-16
Abstract: PURPOSE:To improve the reaction efficiency in the production of the subject substance by the oxidation of 2,3,6-trimethylphenol, by using an oxidizing agent consisting of hydrogen peroxide and an oxidation catalyst consisting of a heteropolyacid having P or Si as a central element and containing Mo or W. CONSTITUTION:The subject substance is produced by reacting 2,3,6- trimethylphenol with H2O2. The reaction is carried out at 10-35 deg.C for 1-15hr using an oxidation catalyst consisting of a heteropolyacid having P or Si as a central element and containing Mo or W. The amount of H2O2 used as the oxidizing agent is 2-10 times the stoichiometric amount and that of the catalyst is 0.001-0.3 times mol of the raw material. The solvent is preferably a water-soluble organic solvent such as acetic acid. Since H2O2 is an inexpensive oxidizing agent which produces water as exclusive by-product, the process is excellent from the viewpoint of the environmental protection. The objective substance can be produced in one step and high yield by this process.

Abstract: PURPOSE:To enable a printing position to be designated in a single stroke, by a method wherein a signal from a detecting pen for detecting a pulse signal impressed on a signal wire of a tablet is selectively used as an item signal or a coordinate signal by a switching means. CONSTITUTION:With an input pen 8 brought into contact with desired coordinates on the tablet 6, a detecting switch 40 is turned ON, then X, Y counters 44, 46 are started by operating a controlling circuit, and the X, Y coordinates are latched by a detection signal. When a position-designating switch 42 is changed over, outputs from X, Y switching circuits 48, 50 are changed over. When normal use of the tablet 6 for outputting an item number is desired, the switch 42 is turned OFF, whereby data inputted into the circuits 48, 50 are outputted to an item number generator 51. When it is desired to designate a printing position, the switch 42 is turned ON, whereby the data inputted into the circuits 48, 50 are outputted to a coordinate-generating circuit 52. Accordingly, it is possible to designate a desired printing position on a printing paper directly from the tablet and to sequentially print characters thereafter, without using display devices.

Subsequently, when the body 1 is depressed forcibly, the lower end face of the body 1 contacts opposingly with a dial 7, and this body becomes a vertically upright state. In this case, the dial 7 is not damaged since a buffer material 2 is stuck to the lower end face of the body 1. When the rotating plate 6 is further rotated, the sliding frame 3 rises along a guide groove 3a vertically in a state that the detaining pawl 3b detains the hands 9-11, and when the upper end shoulder part of this sliding frame is made to press-contact with a stopper 1c of the body 1, its rise stops. In this case, the hands 9-11 are all detached from the hand shaft.

Title: Surface treatment of back plate of brake pad
Inventor: KAMITSUKURI TOSHIO
IPC: C23C8/56
Filed: 1979-05-22
Abstract: PURPOSE: To improve corrosion resistance, by salt nitriding and gas soft-nitriding of the surface of a back plate so as to form a compound layer penetrated deep into the back plate.  
     CONSTITUTION: The surface of a back plate is roughened and salt-bath-nitrided by dipping it in a salt bath of a prescribed composition to form an Fe-C-N compound layer. The back plate is further gas soft-nitrided in an atmospheric heat-treating furnace of a mixed gas of a carburizing gas with ammonia etc. because the compound layer has capillary pores. This treatment removes nearly all capillary pores and increases the thickness of the Fe-C-N compound layer, thereby improving the corrosion resistace. Consequently no rust is produced even under severe conditions at the adhesion interface of the friction material and the back plate, so that pad for disc brake excellent in adhesion is manufactured.
