Title: Preparation of tin hydride
Inventor: SUZUKI NOBORU
IPC: C01B6/06
Filed: 1984-01-27
Abstract: PURPOSE:To obtain tin hydride with high yield by mixing a specified ether with SnCl4 and allowing the mixture to react with LiAlH4. CONSTITUTION:A mixture of SnCl4 with at least one among ethers expressed by the formula (wherein 1<=m<=3, 1<=n<=3, and methyl t-butyl ether, and tetrahydrofuran. The mixture is allowed to react with LiAlH4 at -60-40 deg.C. If the proportion of LiAlH4 to SnCl4 is insufficient, SnCl4 is left as unreacted material; if LiAlH4 is excessive, LiAlH4 remains unreacted. Therefore, >=1/4mol, pref. 4- 5mol LiAlH4 is used per 1mol SnCl4. Sufficient stirring is necessary for proceeding the above described reaction in order to avoid ununiform reaction temp. Moreover, it is preferred to mix LiAlH4 with ether to form slurry and to mix each slurry with each other in order to make the reaction temp. more uniform.

Title: Inverter circuit
Inventor: HARA TAKAHIRO
IPC: H02M7/537
Filed: 1982-01-30
Abstract: PURPOSE:To reduce power loss and to improve efficiency, by providing a power source circuit, which flows a base current to transistors constituting the inverter so that the transistors become the intermediate state between a satureted state and unsaturated state. CONSTITUTION:The base current to the transistor TR1 flows from an auxiliary power source E2 through a switch  SW1. At this time, when a switch SW2 is turned ON, the base current flows from the auxiliary power siurce E2 through the switch SW2, a resistor R1, and a primary winding NP. However, when the switch SW2 is OFF, the current does not flow the resistor R2. That is, the base current to the transistors TR1 and TR2 does not flow through a secondary winding NB. Therefore, the base current is not changed by the voltage of the feedback winding NB, and the transistors TR1 and TR2 can be turned ON and OFF in the ideal state.
