Title: Disk reproducing device
Inventor: NISHIHARA MICHIHARU
IPC: G11B27/10
Filed: 1988-04-08
Abstract: PURPOSE:To select the desired part of the halfway course of a disk and to reproduce it correctly through the use of a simple operation by starting a repeating reproduction from a position, a prescribed time portion before the disk reproducing position at the time when the key input of a start position designating key is inputted, at the time of the repeating reproduction. CONSTITUTION:When an operator finds a spot, he wants to repeating reproduce, during a play mode, he pushes a repeat start memory (RSM) key 19b, and the track number of a recording track at the said spot is registered. Next, afterwards, when contents, he wants to reproduce again, are finished, the operator pushes a repeat end memory (REM) key 19c, and the track number of the recording track at the said finished spot is registered. In such a way, the device is constituted so that the track numbers SM, EM to be registered are stored after subtracting the prescribed value previously, considering a time lag from the finding of the spot, desired to be reproduced, till the pushing of the RSM key 19b. Thus, the time lag, accompanied with the key operation, can be compensated, and the positioning of the repeating reproduction starting position can be performed correctly.

Title: Image forming device
Inventor: KURITA ATSUMI
IPC: G03G15/20
Filed: 1995-04-13
Abstract: PURPOSE: To shorten the time required for copying and to improve productivity by executing a copying action at a high speed when the number of copying sheets is small and switching the copying speed to be high from low after a pressure roll is warmed when the number of copying sheets is large. CONSTITUTION: When a copying start signal is inputted from an interface, it is judged by a CPU whether the number of copying sheets is large or small by comparing it with the prescribed number of sheets N0. Then, when the number of copying sheets N is smaller than the prescribed number of sheets N0 (N<N0), the copying action is executed at a high speed (high speed rotation or high CPM). When the number of copying sheets N is larger than the prescribed number of sheets N0 (N>N0), the copying action is started at a low speed first and the high-speed copying action is started by switching the copying speed to be high when the temperature (t) of a heating roll is lower than the prescribed temperature (t2) and it becomes more than the prescribed temperature (t3) thereafter. Thus, an image can be fixed in the shortest copying time regardless of the number of copying sheets.

Title: Air conditioner for automobile
Inventor: UEDA TOSHIAKI
IPC: B60H1/32
Filed: 1981-06-10
Abstract: PURPOSE:To improve the durability of a heat exchanger by a method wherein coolant and exhaust gas are heat-exchanged through the heat exchanger and an exhaust gas heat exchanger, both of which are contacted with each other only during the time when the heat pump is put into operation, and the heat exchanger is prevented from becoming high temperatures by separating the heat exchanger from the exhaust gas heat exchanger when exhaust gas becomes high temperatures or the like. CONSTITUTION:The heat exchanger 19 is so constituted as to be able to contact with the separate from the exhaust gas heat exchanger 3 by being shifted through a motor 23, a screw 24 and a spring 25 by the use of flexible tubes 18a and 18b in the coolant passages before and after the heat exchanger 19. When the heating is intended by recovering the heat of exhaust gas by means of heat pump system, the heat exchanger 19 and the exhaust gas heat exchanger  3 are brought into contact with each other so that the heat is exchanged from exhaust gas into coolant and, after that, radiated from an interior heat exchanger 17. On the other hand, when the heating with coolant is not necessary, the heat exchanger 19 and the exhaust gas heat exchanger 3 are separated from each other so that the heat does not exchanged from exhaust gas into coolant. Consequently, the deterioration of the heat exchanger 19 due to high temperature and the thermal cracking of coolant are prevented, resulting in enabling to improve the durability of the heat exchanger.
